Job J125: MCP adapter over the shared action route.

Scope:

  • Add infraternal mcp over stdio with initialize, tools/list generated from the shared action registry, and tools/call dispatched through the existing action route using MCP's own signed-in API-key authority.
  • Assess streamable HTTP against the current server and existing dependencies; include it only if it is a small adapter with no unjustified new dependency.
  • Preserve the registry's action names, descriptions, JSON schemas, CLI help text, refusal codes, and refusal guidance. Do not define actions or dispatch handlers a second time.
  • Add protocol and unauthorized-call coverage, plus a real MCP-client end-to-end case if a compatible client is present in the VM dev shell.
  • Measure the static binary before and after and report the delta.

Plan and estimate (4–6 hours of implementation and review, excluding VM queue time):

  1. Start from J94's route branch origin/apikey-actions-303 at 067c3e233bcf0235332abf278a74f89c34172bf8, rebase onto current origin/dev 7add126405a9205bb817a154af11fad2c438cd45, and confirm the route contract with #303.
  2. Read D318, D299, D303, D304, D314, docs/CLI.md, and the action registry; trace CLI text, authority, errors, and shared dispatch.
  3. Implement the narrow MCP transport adapter and authority handoff; avoid a new dependency unless measured and justified.
  4. Add protocol, authority, and available real-client coverage; record before/after static sizes.
  5. Check both VM build queues, run scripts/verify fast on the less-loaded eligible VM through build-slot, wait for completion, then commit and push this branch and post the final SHA, size table, and gate output verbatim.

Contract constraint: MCP is a thin adapter over the one shared action route. No MCP-only action definitions, second dispatch path, or changes to numbered decisions.

Started implementation on branch j125-mcp in /home/kayg/Developer/Worktrees/infraternal-J125. The branch started from the current #303 route head 067c3e233bcf0235332abf278a74f89c34172bf8 and was rebased onto origin/dev base 7add126405a9205bb817a154af11fad2c438cd45. I will keep MCP as a generated thin adapter and use the shared action route. Estimate: 4–6 hours implementation and review, excluding VM queue time.

Finding: the current CLI registry already carries each hosted ActionDef alongside its CLI description and JsonSchema. CLI execution uses cli/api_actions.rs, which loads the private sign-in credential, enforces the descriptor's explicit api_scope, scrubs bearer material from responses, and dispatches normal calls to POST /v1/actions/{action_id}. The existing SSH bootstrap and host-removal approval flows are special cases within that same hosted adapter. MCP can therefore generate from registered hosted definitions and reuse that adapter instead of adding action definitions or server dispatch.

Streamable HTTP assessment: the CLI crate currently compiles Hyper with its client/http1 features, and its current networking helper is client-only. An HTTP MCP transport would need an inbound listener plus an ingress authentication and lifecycle boundary in addition to stdio. That is not a small adapter over the current action route, so J125 will ship stdio only and add no HTTP dependency or second listener.

Finding: D28 requires a dry run before a destructive MCP call. The registered remote.host.remove action is destructive and marks dry-run as required, but its registered MCP input schema contains only host_id and has no dry_run field. J125 therefore excludes destructive actions from tools/list unless their shared schema requires a boolean dry_run input, and tools/call rejects calls to excluded actions. This keeps the action registry and route unchanged and does not create a duplicate dry-run action.

Progress: MCP stdio, registry-generated tool metadata, shared hosted credential/scope dispatch, protocol errors, and unauthorized-call coverage are committed on j125-mcp at f73d3e6fb. Baseline static sizes from compute01 at the unmodified base 28ffb4bfdf: x86_64 22,762,256 bytes; aarch64 20,735,176 bytes. No dependency added. Next: run scripts/verify fast on the least-loaded VM, measure both final sizes, then amend to the final commit message and post the gate receipt.

J125c takeover (Claude Sonnet 5.5) of J125 after the previous job stopped on a provider 429 at about 07:00 UTC.

State found:

  • Branch j125-mcp head f73d3e6fb (3 WIP commits on base origin/dev 7add12640: two are J94's #303 route commits, one is J125's MCP commit). No uncommitted work in the control-host worktree or in either VM worktree (~/worktrees/J125 on compute01 at f73d3e6fb, on dev-02 at 28ffb4bfd). Current origin/dev is 7c082bddf.
  • No J125 process is running on either VM. Leftovers: a 14 GB target/ in compute01 ~/worktrees/J125 and ~/.cache/codex-scratch/J125 (baseline-size.log: x86_64 22,762,256 B, aarch64 20,735,176 B, recorded in the previous progress comment). No gate log exists, so the two unit failures I was told about are not on record and I will reproduce them myself.
  • The base is stale: J94c's apikey-actions-303 head 73664b9d5 changed cli/api_actions.rs, command_tree.rs, main.rs and sign_in.rs after J125's base, and J125 rewrote most of api_actions.rs. I rebuilt the stack as origin/dev 7c082bddf + J94's three WIP commits (clean rebase) + J125's commit (one conflict in api_actions.rs, resolved by keeping J125's shared call_action_with_output and J94's clone_into lint fix) on a new branch j125c-mcp. I will not force-push j125-mcp.
  • Contract of record on #313 is the J94 comment of 2026-11-02 23:06 UTC (POST /v1/actions/{action_id}, hosted_action CLI hook). J94c has not re-published; I will re-check after its squash and rebase onto it.

Remaining plan:

  1. Build and run the infraternal crate tests; reproduce the root help line width and hosts list parser failures on unmodified origin/dev and on the stack without my commit, to separate inherited failures from ones J125 caused (30-60 min).
  2. Fix the failures J125 caused, with a failing test first (30 min).
  3. Review the MCP adapter against the #313 contract (no duplicated auth, schemas from the registry) and fill protocol gaps (30-60 min).
  4. Squash into atomic commits with full messages, rebase onto J94c's published head, measure static sizes, run scripts/verify fast through build-slot on the freer VM, and post the head SHA and output verbatim (gate time plus queue).

Estimate: 3-4 hours plus queue time.

J125c findings (Claude Sonnet 5.5). Branch j125c-mcp, stacked as origin/dev 7c082bddf + J94's three WIP commits (rebased, clean) + one MCP commit. j125-mcp is untouched.

1. Which failures are inherited, and which J125 caused. cargo test -p infraternal --bins on compute01:

  • Unmodified origin/dev 67556332b: 128 passed, 0 failed. Nothing is inherited from dev.
  • J125's original head f73d3e6fb: 8 failed, 138 passed.
    • J125's own: root_help_lines_fit_80_columns (95 columns: mcp Serve registered server actions to an MCP client over standard input and output.), mcp::an_unauthorized_call_keeps_the_cli_refusal_text_and_code, mcp::initialize_and_tool_list_follow_the_registered_cli_metadata.
    • Inherited from the J94 WIP commits it was built on, and fixed by J94c's 73664b9d5: server_action_commands_use_the_shared_action_definitions (this is the hosts list parser expectation, panic at command_tree.rs:391), every_command_in_the_tree_takes_json, public_help_is_plain_words, removal_and_retention_inputs_keep_the_production_runtime_bindings (clap debug assert at debug_asserts.rs:110) and sign_in::stored_key_selection_requires_one_server_or_an_explicit_origin. They all pass on the rebased stack.
  • Stack with my fixes: 147 passed, 0 failed, 1 ignored.

2. Safety hole in J125's destructive-action filter (D28). Two registrations share the hosted id remote.host.remove: hosts remove and the remote plugin's remove-host. The plugin sets effect=Destructive and dry_run=Required in its contract but leaves the advisory safety notes empty. J125's is_mcp_tool read only the notes, so remove-host (inputs host, server, no dry_run) was listed and callable. Fixed: the filter now reads the contract and the hosted ActionDef. A test covers every registration that shares that id.

3. Refusal text was split across lines. The error text came from the pretty renderer, which clamps at 100 columns, so the 109-character "not signed in" sentence was hard-wrapped for a client reading one string. The text now comes from the unwrapped message, detail and next steps.

4. Real-client coverage. The VM dev shell has no MCP client (claude, codex, inspector and the Python mcp package are all absent; no SDK in the lockfile). I added crates/infraternal/tests/mcp_stdio.rs, which drives the real infraternal mcp binary over stdin/stdout: handshake, tools/list, an unsigned call refused with not_allowed, the removal tool absent, pre-initialized calls refused, clean exit at end of input, and stdout holding only JSON-RPC. I did not add a client library for this.

5. First gate run on 4b8e00030: fmt FAIL, clippy FAIL (9 findings, all in mcp.rs / emit_failure), test FAIL. The test failure was a link error caused by my own probe: a shared target kept a build-script linker path inside a probe worktree I had removed. Everything else passed, including static builds. Fixed in e4baecdd6; the gate is rerunning.

J125c finish (Claude Sonnet 5.5). Branch j125c-mcp, head 2636dc9c03b3fd78429ceb8e2bbbf60c1bdde3a3: one commit on J94d's apikey-actions-303 head 842fbf1d7 (which sits on dev bcca3054f). j125-mcp is untouched. When J94 is rebased or squashed again, replay the one MCP commit with git rebase --onto <new J94 head> 842fbf1d7 j125c-mcp.

Contract changes since the first takeover comment. I rebased onto J94d's new head after reading its updated route contract on #313 (comments 76765, 77006). MCP now asks ActionDef::key_callable() instead of api_scope.is_some(), as the contract says. The D28 rule stays on top: a destructive or dry-run-required action is listed only when its registered input requires a boolean dry_run. No auth, dispatch or action definition was added; MCP reuses the hosted adapter, the stored device credential and the POST /v1/actions/{id} route.

+---------------------------+--------------+
VERIFY_EXIT=1

Both failing rows come from J94d's commits, not from the MCP commit:

  • fmt: diffs in infraternal-plugin-api/src/lib.rs, infraternal-server/src/api_actions.rs, auth/api_actions_tests.rs, bootstrap_api_tests.rs, infraternal/src/sign_in.rs, and two places in infraternal/src/cli/api_actions.rs (terminal_safe and a test). git blame puts those lines in J94d's 64764d79a; my commit touches none of them.
  • clippy: clippy::double_must_use in infraternal-server (lib test). It stops the run at that crate.
  • Because that stops the workspace clippy, I linted my crate on its own at this head: cargo clippy -p infraternal --all-targets --locked -- -D warnings passes (rc 0; the one warning is in vendored russh). rustfmt --check is clean on cli/mcp.rs, cli/actions.rs, tests/mcp_stdio.rs.
  • The test row passes, so the 10 infraternal-server failures seen on the earlier stack are fixed upstream. It includes the MCP unit tests (new no_destructive_registration_is_listed_without_a_dry_run_input) and tests/mcp_stdio.rs.

Flaky tests in the infraternal bin (not reproduced on this head): on the previous head e4baecdd6, one run failed cli::command_tree::tests::public_help_is_plain_words (I did not capture its message) and a workspace run failed restart::tests::deleted_path_review::relative_recovery_after_atomic_install_keeps_live_install_path ("Text file busy", a fork/exec race). Eight repeated cargo test -p infraternal --bins runs at that head all passed, and the help test passes when run alone. I could not prove the help flake pre-exists; the 24 other failures in that workspace run were identical with and without my commit.

Static size (musl release, compute01), exact before/after:

target J94d head 842fbf1d7 with MCP 2636dc9c0 delta

No dependency added. Streamable HTTP is not included (decided earlier on this issue).

Cleaned up: VM worktree ~/worktrees/j125c and its target removed; nothing of mine is running. ~/worktrees/J125 (the previous job's, now without its target) is left for its owner.

Flaky tests in the `infraternal` bin (not reproduced on this head): on the previous head `e4baecdd6`, one run failed `cli::command_tree::tests::public_help_is_plain_words` (I did not capture its message) and a workspace run failed `restart::tests::deleted_path_review::relative_recovery_after_atomic_install_keeps_live_install_path` ("Text file busy", a fork/exec race). Eight repeated `cargo test -p infraternal --bins` runs at that head all passed, and the help test passes when run alone. I could not prove the help flake pre-exists; the 24 other failures in that workspace run were identical with and without my commit. **Static size (musl release, compute01), exact before/after:** | target | J94d head 842fbf1d7 | with MCP 2636dc9c0 | delta | |---|---|---|---| | x86_64 | 22,795,408 B | 22,864,496 B | +69,088 B | | aarch64 | 20,761,576 B | 20,819,080 B | +57,504 B | No dependency added. Streamable HTTP is not included (decided earlier on this issue). **Cleaned up:** VM worktree `~/worktrees/j125c` and its target removed; nothing of mine is running. `~/worktrees/J125` (the previous job's, now without its target) is left for its owner.

J147 (Claude Sonnet 5.5): design for MCP events on the thin adapter. Branch mcp-events-j147 on J125c 2636dc9c0 (J94d 842fbf1d7; origin/apikey-actions-303 is now b0d41158a, I will rebase when it lands). Spec reading done 2026-11-03.

What the spec offers (latest = 2026-07-28; previous 2025-11-25)

  • Changelog: https://modelcontextprotocol.io/specification/2026-07-28/changelog
  • 2025-11-25 and older ("legacy"): initialize handshake; resources capability {subscribe, listChanged}; resources/subscribe -> notifications/resources/updated {uri}; notifications/resources/list_changed; notifications/tools/list_changed; progress; logging. https://modelcontextprotocol.io/specification/2025-11-25/server/resources
  • 2026-07-28 ("modern"): stateless, no initialize, every request carries _meta (io.modelcontextprotocol/protocolVersion, clientCapabilities, clientInfo); mandatory server/discover; UnsupportedProtocolVersionError (-32022, data.supported); subscriptions/listen replaces resources/subscribe and the HTTP GET stream (filter toolsListChanged, resourcesListChanged, resourceSubscriptions: [uri]; first message notifications/subscriptions/acknowledged; every notification tagged _meta."io.modelcontextprotocol/subscriptionId"; client cancels with notifications/cancelled; server ends with a complete result; stdio reconnect = client re-sends listen); results carry resultType; list results carry ttlMs/cacheScope; Logging, Roots, Sampling deprecated; resource-not-found is -32602. https://modelcontextprotocol.io/specification/2026-07-28/basic/patterns/subscriptions , .../server/discover , .../basic/versioning , .../basic/transports/stdio
  • There is no separate "events" feature. Server-to-client events are: resource updates (subscriptions), list_changed, request-scoped progress and message. Notifications are invalidations: the client re-reads the resource. That is the same shape as our changed events (contracts/mesh-api.md section 4).
  • Compatibility rule (versioning page): a dual-era server picks the era from how the client opens. _meta on the first request -> modern. initialize -> legacy, scoped to the stdio process. Clients probe stdio with server/discover and fall back to initialize on any non-modern error.

Design

  1. Dual-era stdio server. initialize keeps today's behaviour (negotiate down to 2024-11-05 / 2025-03-26 / 2025-06-18 / 2025-11-25). Requests with modern _meta are served statelessly: server/discover, tools/list, tools/call, resources/*, subscriptions/listen. Unknown modern version -> -32022 with supported. Capabilities only advertised to clients that can use them: resources.subscribe and listChanged are only sent in the initialize result (legacy), and honoured in subscriptions/listen (modern) per the client's filter. Old clients see no change in tools.
  2. Event -> MCP mapping (resources are views of registered read actions, so reads go through the one action route):
infraternal event source (server, existing) MCP resource read via scope MCP mechanism
remote.hosts topic (host added, removed, connected, disconnected) infraternal://hosts remote.host.list hosts:read resources/updated
terminal.sessions topic (session started, ended) infraternal://sessions sessions.list sessions:read resources/updated
none (no change feed) infraternal://status server.status status:read readable, not subscribable
key revoked/expired, scopes tools stream closes; adapter emits tools/list_changed after re-listing
mesh changes not exposed: no key-callable mesh read action yet add a resource when one is registered
approvals pending, inbox items no server event or read action exists not invented here; resource is added with the action
long-running action notifications/progress only for the add-host stream, if a progressToken is sent (follow-up)
Logging is deprecated in 2026-07-28 and is not implemented (diagnostics stay on stderr).
3. One event route (D318). The adapter subscribes on the server's existing GET /v1/ws control stream with Subscribe frames, the same topics the web app uses. contracts/wire.md section 7 already says leg A admits "the session cookie or a device API key", but the code only admits the cookie. So the one server change is: /v1/ws admits a bearer key in a events-only profile (Subscribe/Close only, topic -> scope check before dispatch, key revocation/expiry closes the socket through the existing authority watchdog). No second endpoint, no second authorization path, no terminal or action traffic on a key socket.
4. No new dependency. Wire codec is the workspace's infraternal-protocol; WebSocket client is the tokio-tungstenite the CLI already ships under remote. An MCP SDK crate is not needed: the adapter is ~1k lines and the spec surface is small.
5. Adapter becomes async (stdin reader task + select over requests, event stream, cancellation) so notifications can be pushed between requests. Reconnect: bounded backoff, resubscribe, and on every (re)connect send one updated per subscribed URI (the missed-change case), as our snapshot-on-subscribe semantics allow.

Open items / blockers

  • test.ssh.kayg.org runs an older build: POST /v1/actions/remote.host.list answers 405 (the SPA fallback). Without J94d's route there is no key-callable action there, so the action and event scenarios cannot run against it until it is deployed with this stack. I was told not to deploy. Plan: run the scenario suite against a server built from this branch on compute01 (same code, real sign-in flow, real passkey approval via the software authenticator), and run against test.ssh.kayg.org whatever its build supports (sign-in, key issue). I will report this for the owner/orchestrator to decide on a test-server deploy.
  • Tool listing per scope: the adapter lists by registry, not by key scope. I will check whether the server exposes the key's scopes.

J147 progress (Claude Sonnet 5.5), branch mcp-events-j147 at 3fa688f62 (WIP commits; I will regroup them into atomic commits before the final report). Based on J125c 2636dc9c0; J94d's branch has since moved to b0d41158a, I rebase when it lands.

Built

  • Server: GET /v1/ws now admits Authorization: Bearer <key> in an events-only profile (the access wire.md section 7 already promised). Hello/Welcome as for the browser (no resume), then only Subscribe/Close. Topics: remote.hosts needs hosts:read, terminal.sessions needs sessions:read; auth.recovery, mesh, canvas.layout are not offered to keys. Key liveness is event-driven (account revocation event + one timer at the key's deadline), same J90 authorizer and per-key limit/audit as the action route. Files: websocket/key_events.rs, small hooks in websocket.rs, api_actions.rs, runtime.rs.
  • CLI infraternal mcp: dual-era stdio server. initialize keeps the old eras (2024-11-05..2025-11-25) and adds resources + resources/subscribe. Requests with _meta protocolVersion 2026-07-28 are served statelessly: server/discover, tools/*, resources/*, subscriptions/listen (ack first, tagged notifications, notifications/cancelled, graceful completion at end), resultType, ttlMs/cacheScope, -32022 with the supported list. Tools and resources are listed per the stored key's scopes. Resources: infraternal://hosts, infraternal://sessions (subscribable), infraternal://status. A read is the registered read action through the one action route. Event link mcp/events.rs is a client of the same /v1/ws. No new third-party dependency (the workspace's own infraternal-protocol crate is now a CLI dependency under remote; Cargo.lock edited by hand for that edge).
  • stdin is read by a thread so notifications can be pushed between requests; a tool call in flight is cancellable.

Evidence so far (compute01, cargo test, CARGO_TARGET_DIR under codex-scratch/j147)

  • cargo test -p infraternal -p infraternal-server -- mcp key_events: 21 CLI protocol tests ok, 5 server real-socket tests ok (admission, scope-limited topics, frame allow-list, revocation closes the socket, deadline closes the socket).
  • cargo test -p infraternal --test mcp_stdio: 4 ok (process boundary, both eras, listen ack/completion at EOF).
  • cargo check -p infraternal-server -p infraternal --tests --locked: no warnings from my files.

Next: live scenarios. Reminder of the blocker from the design comment: test.ssh.kayg.org runs a build that predates POST /v1/actions (405), so key-callable actions and the event socket do not exist there. I was told not to deploy, so route-dependent scenarios will run against a server built from this branch on compute01; sign-in/approval will run against the real test server.

J147 scenario run (Claude Sonnet 5.5). Server: infraternal server built from branch mcp-events-j147 head 50ca636c7 (J94d d8c8f4a04 + J125c + this work), HTTPS with a throwaway CA, on compute01 (own HOME/runtime dir). Client: the real infraternal mcp process over stdio, plus the official TypeScript SDK 2.4 and 1.32 clients and the official Inspector CLI 2.13 (installed in a temp dir, no repo dependency).

Totals: 36 pass, 0 fail, 7 blocked (blocked = the environment cannot run it; the reason is in the row).

What this is not: the keys are seeded in the local server's SQLite (owner row + api_keys rows), because the passkey approval ceremony cannot run on a local origin with the orchestrator's software authenticator (bound to test.ssh.kayg.org), and because the real test server cannot complete infraternal sign-in at all (rows R2 to R4). The ceremony itself is J94d's and J79d's.

BLOCKED rows, in plain words

  • S10c, S10d, S11: the test host runs the server as a non-root account; starting a terminal needs a per-person login, which the agent refuses (terminal unavailable, reason invalid). So no real session could start to cause a change on this host. What is covered instead: the first notification after each subscribe on the live server (S10b, C1, C2), the resync after a server restart (S12), and the Rust test a_session_inventory_change_is_pushed_to_a_subscribed_key_socket that bumps the same signal the server bumps when a session starts or ends.
  • R2 to R5: test.ssh.kayg.org runs a build that predates J94d's route. POST /v1/actions/... answers 405; /auth/device-start accepts only hosts:read, terminal:connect, actions:dry-run (the CLI always asks for sessions:read and status:read, so it gets 400 and prints "The server returned a response this command could not use"). Sign-in, key-callable actions and the event socket therefore cannot be exercised there until the stacked branch is deployed. I did not deploy (task rule).

Things the run found that are fixed in the branch

  1. ssh.start (add-host) through a key could never open its stream: hand-built WebSocket request without the handshake headers (comment 77118 on #303; fixed in commit 6dff335bd).
  2. The official v2 client rejected resources/read results without ttlMs/cacheScope (2026-07-28); fixed.
  3. A script that wrote requests and closed stdin lost the answers of calls in flight; fixed, with a regression test.
  4. Host removal had vanished from MCP under D333; it is back with a required dry_run and a preview-first rule (D28).

Found in J94d's code, not changed here: a remote.host.remove dry run for an unknown host returns 403, which the CLI renders as "Signed out: your key expired or was revoked" (S07d). A valid key gets told it is signed out; the server should answer 404 or 400 for a host it does not know, or the CLI should not map every 403 to the key diagnostic.

Driver and raw results are attached to this comment (j147_scenarios.txt is a Python 3 script, standard library only; run with INFRATERNAL_BIN=<binary> J147_REAL=1 J147_CONF=<dir with the SDK clients> python3 j147_scenarios.txt).

J147 scenario run (Claude Sonnet 5.5). Server: `infraternal server` built from branch `mcp-events-j147` head `50ca636c7` (J94d `d8c8f4a04` + J125c + this work), HTTPS with a throwaway CA, on compute01 (own HOME/runtime dir). Client: the real `infraternal mcp` process over stdio, plus the official TypeScript SDK 2.4 and 1.32 clients and the official Inspector CLI 2.13 (installed in a temp dir, no repo dependency). **Totals: 36 pass, 0 fail, 7 blocked** (blocked = the environment cannot run it; the reason is in the row). **What this is not:** the keys are seeded in the local server's SQLite (owner row + `api_keys` rows), because the passkey approval ceremony cannot run on a local origin with the orchestrator's software authenticator (bound to test.ssh.kayg.org), and because the real test server cannot complete `infraternal sign-in` at all (rows R2 to R4). The ceremony itself is J94d's and J79d's. | ID | Scenario | Expected | Observed | Result | |---|---|---|---|---| | S01a | stateless client: server/discover, no handshake | supportedVersions [2026-07-28], resultType complete | {"supportedVersions": ["2026-07-28"], "resultType": "complete"} | PASS | | S01b | unknown protocol version in _meta | error -32022 with data.supported | {"code": -32022, "supported": ["2026-07-28"]} | PASS | | S01c | no _meta, no initialize | error -32002 not initialized | -32002 | PASS | | S01d | stateless tools/list carries cache hints | resultType, ttlMs, cacheScope=private | {"resultType": "complete", "ttlMs": 60000, "cacheScope": "private"} | PASS | | S02-2025-11-25 | handshake-era client asks for 2025-11-25 | negotiates 2025-11-25; no 2026-only fields | negotiated 2025-11-25; tools=3; resources=3; leaked=[] | PASS | | S02-2025-06-18 | handshake-era client asks for 2025-06-18 | negotiates 2025-06-18; no 2026-only fields | negotiated 2025-06-18; tools=3; resources=3; leaked=[] | PASS | | S02-2025-03-26 | handshake-era client asks for 2025-03-26 | negotiates 2025-03-26; no 2026-only fields | negotiated 2025-03-26; tools=3; resources=3; leaked=[] | PASS | | S02-2024-11-05 | handshake-era client asks for 2024-11-05 | negotiates 2024-11-05; no 2026-only fields | negotiated 2024-11-05; tools=3; resources=3; leaked=[] | PASS | | S02-2099-01-01 | handshake-era client asks for 2099-01-01 | negotiates 2025-11-25; no 2026-only fields | negotiated 2025-11-25; tools=3; resources=3; leaked=[] | PASS | | S03 | tools and resources listed per stored key scope | status:read -> server.status only; read -> +sessions.list, remote.host.list; write (hosts:write) -> +ssh.start, +remote.host.remo… | {"status": ["server.status"], "status:resources": ["status"], "read": ["remote.host.list", "server.status", "sessions.list"], "read:resources": ["hosts", "sessions", "status"], "write": ["remote.host.list", "remote.host.remove", … | PASS | | S04 | read actions through tools/call and resources/read | all six succeed | {"server.status": true, "sessions.list": true, "remote.host.list": true, "read:hosts": true, "read:sessions": true, "read:status": true} | PASS | | S05a | write without the scope (client-side, key file lacks hosts:write) | isError with sign-in --scope guidance | This device key does not include hosts:write.

J94f (#303, D336) → J147: apikey-actions-303 moved past 3900a11c5. Head is now 7b781b33a, and more commits may follow (fmt/clippy folds, then the gate). I will post the final gated head here and on #303. Please rebase the MCP stack onto that one.

What changed (auth only, no MCP files touched): a per-action passkey tap is now bound to one action (login-start {action} → sessions.tap_action, migration 0048, spent once within 120 s). Files: crates/infraternal-server/src/auth/{action_tap,devices,security_settings,recovery_rotation,sessions,webauthn,http,mod}.rs, tests, contracts/{keywrap,plugin}.md, apps/tracer/src/{auth,device-approval.on-demand,recovery-auth}.ts. remote_migration_tests.rs now expects 0043..0048. If your branch adds a migration, it needs 0049+. The key-callable action set, /v1/actions and the API key paths are unchanged.

J147: request to deploy the rebased stack to test.ssh.kayg.org. Branch mcp-events-j147, head b9f970e89d1c655316fd27592022616fa6f0b356 = J94e's 3900a11c5 + J125c's MCP commit + my commits (events-only key socket on /v1/ws, MCP resources and both protocol generations, the J154 fixes, and the server's review token carried by the MCP removal tool in place of my session-local rule). Not merged. Please deploy this head; I then run the blocked scenarios R2 to R5 and S10c, S10d, S11 against it with keys approved through infraternal sign-in and the software passkey, and post the table here. I am watching the server (POST /v1/actions/... stops answering 405) and will start on my own when it changes.

Rebase: git rebase --onto 3900a11c5 d8c8f4a04. Conflicts were only in cli/api_actions.rs (J125c's commit against J94e's CLI removal flow). Result there: a person's hosts remove keeps J94e's review, confirm, remove flow; MCP calls the route's two steps directly (dry_run true returns review_token and review_expires_in in structuredContent; the real call passes the token back; the server's review_required / review_invalid text is the tool error). yes and root are not offered to an AI client. My session-local "preview first" code is deleted. A test checks the token passes through unchanged and that nothing in the adapter holds a real call back.

VERIFY_EXIT=0

Notes on the gate: (1) The first full run at this head failed test on ten_concurrent_streams_deliver_their_first_keyframe_through_the_server_relay (desktop plugin, code this stack does not touch); it passed 5 of 5 alone with its features, host load average was 26 to 36, and the second full run is the green one above, so I treat it as a load flake. (2) scripts/verify quick does not finish on this stack. Because the stack changes Cargo.lock, quick picks --workspace scope, and cargo test --workspace --lib --bins then runs the fuzz crate's binaries as unit tests: the libFuzzer binary auth_cookie ran unbounded for 50 minutes until I stopped it. fmt and clippy (the first two quick stages) passed in that run. A bounded run (-runs=N) or leaving the fuzz crate out of quick's test scope fixes it; I did not touch scripts/verify.d/quick.sh.

Static size at this head (musl release, compute01): x86_64 23,020,976 B, aarch64 20,951,224 B. Against J94d's d8c8f4a04 (22,719,024 and 20,701,320 B) that is +301,952 B and +249,904 B; J94e's own part of the change is included in both numbers, so the MCP and event part is the smaller share.

J147: first run against the deployed test server (keys approved through infraternal sign-in and the software passkey). CLI at b9f970e89. Totals: 11 pass, 9 fail, 2 blocked.

What the run shows about the deployed build: it is not the stack I asked for. A valid key on GET /v1/ws answers 403 Forbidden (R5: my events-only key profile is absent), and a dry run of an unknown host still answers 'Signed out: your key expired or was revoked' (J94e's 404 fix 3900a11c5 is absent). Everything that depends only on J94's route and scopes works, with real keys: sign-in with the 24 h approval page (E1a, E1b), tool listing per scope (E2), reads (E3), write with and without scope (E4), a key revoked from the app (E6b), the rate limit (E7), and the official Inspector (E10-C3). The subscription tests fail because the server side of the one event route is not there: the adapter's subscriptions/listen is acknowledged, but no event ever arrives (E9a, E10-C1, E10-C2).

Two things I need:

  1. Deploy my head, not an older J94 build. mcp-events-j147 @ b9f970e89d1c655316fd27592022616fa6f0b356 (it contains J94e's 3900a11c5). J94f says apikey-actions-303 has moved to 7b781b33a and will move again; when J94f posts the final gated head I rebase and give you the new SHA. If you would rather deploy now, b9f970e89 is gated and green.
  2. Enrol one throwaway host into test.ssh.kayg.org (for example infraternal-dev-02-std). The test server runs without root and has no account matching orchestrator, so opening a terminal answers no_login (E9b: This server runs without root and has no user account matching your name). No session can start there, which keeps S10c, S10d, S11 (a real session start causing a sessions change) blocked, and there is no host to dry-run a removal against (E5b). With one enrolled host I can run all of them, and the removal dry run only previews: I will not remove a host unless you say so.

Notes: the browser helper hits the server's sign-in rate limit when two passkey sign-ins run within a minute ('Too many attempts. Wait a minute'), so my runs space them 75 s apart. My helper scripts and the results file are attached.
