fix: add an MCP status command and report discovered-config drift - #1160
Conversation
Two defects where the diagnostic information already exists in the
process and is discarded before it reaches the user.
`server unavailable` logged `status.status` — the constant string
`"failed"` on that branch — and dropped `status.error`, the field
holding the actual message (`401 Unauthorized`, a transport error,
`Invalid MCP URL for "<key>"`). Extracted `unavailableLogFields()` as a
pure function so the payload is testable without standing up a
transport, and so a later edit cannot quietly drop the field again.
Environment variables that resolve to empty were never named. A
`{env:VAR}` with nothing set becomes `""`, the config parses clean, and
the server launches with a blank credential — usually a password —
failing later with an error naming neither the variable nor the file.
The names are now recorded at both substitution sites: per-server for
discovered external configs, per-file for the main config. They surface
in `/mcps` and `mcp list`, shown even when the server reports connected,
because a blank credential often connects and fails on first real use.
An unresolved bare `${VAR}` is deliberately left literal by the config
layer so a later runtime layer can fill it (the bedrock provider fills
`${AWS_REGION}` from the effective region). That case is not reported.
Closes #1121
Closes #701

`status` is the name people reach for when a server will not connect, and it was the one name that did not exist. The gap was narrower than it looks: `mcp list` already probed live and already printed the failure reason, so `status` is registered as a sibling sharing that handler rather than a second view to keep in sync. It is a distinct command rather than an alias because an alias widens yargs' alias column enough to rewrap unrelated sibling rows in the help output. MCP discovery is first-source-wins, so a server already present in the user's config was skipped outright and a changed `.vscode/mcp.json` — a new port, a moved command — was never mentioned. `driftFields()` now reports which fields disagree, naming nested keys individually (`environment.ALTIMATE_EXTENSION_RPC`) so the message points at the thing to fix. The configured value still wins; silently overwriting a user's own config would be worse than the silence it replaces.

WARNING: DRIFT_IGNORED omits updatedAt, so datamate-synced servers always report a spurious updatedAt drift
normalizeMcpConfig preserves updatedAt on configured entries (config.ts:107, config.ts:127) and datamate-transport.ts writes it when syncing the datamate entry from .vscode/mcp.json into altimate-code.json. Discovery's transform in this file never copies updatedAt, so every comparison sees it present on the configured side and undefined on the discovered side — JSON.stringify(undefined) !== JSON.stringify("...") reports it as drift. A datamate-synced server therefore prints "differs from ...: updatedAt (config wins)" on every mcp list/mcp status.

SUGGESTION: sources.join(", ") attributes drift to every contributing source, not the source that defined the server
sources is the full contributingSources list from discoverExternalMcp, so when a project has servers from several files (.vscode/mcp.json, ~/.claude.json, ...), the "differs from X" message names all of them for every server. This weakens the "where to look" signal that #878 is meant to provide. Consider tracking the per-server source (e.g. in addServersFromFile) and passing that instead.

Addresses the review findings on this PR.
`_unresolvedEnv` only ever grew. The recording site sits inside an
`unresolvedNames.length > 0` guard, so a discovery run where every
variable resolved never touched the map — a server whose `{env:VAR}`
had since been set kept its old entry and `/mcps` went on telling the
user to set a variable that already worked. It is now cleared at the
start of each `discoverExternalMcp` and unioned within that run, which
is what the docstring already claimed. Clearing per run also stops one
project's discovery from mixing into another's under a shared server
name, and stops the map growing for the life of the process.
`_blankedEnv` had the mirror-image defect. A remote config substitutes
its `url` and then each header separately, all under one source, and
each call *replaced* that source's record — so a blank credential found
in the url was erased by a later clean header call and `mcp list` never
mentioned it. Substitution now unions, with an explicit
`resetBlankedEnvVars` at the two load sites.
Two tests were not testing what they claimed:
- The `/mcps` "says nothing extra" case compared `formatMcpStatusForDisplay(..., [])`
against the same call with the argument omitted, which defaults to `[]`.
Both sides were byte-identical, so it passed even if the function
appended an "unresolved" suffix. It now asserts against a literal.
- The `mcp list` E2E test asserted only that the server name appeared
and that argument parsing had not broken. It never asserted the
failure reason reached the user, which is this PR's entire point — it
passed with `status.error` dropped. It now requires the surfaced
error text.
New tests cover the staleness fix in both directions: a variable that
gets set stops being reported, and one that stays unset keeps being
reported across runs. Mutation-tested — removing the reset fails the
first.
Full opencode suite: 11489 pass, 0 fail.

Merges the env-diagnostics branch and addresses this PR's review findings.
`updatedAt` now joins DRIFT_IGNORED. `normalizeMcpConfig` preserves it on
the configured entry and discovery never produces one, so every
comparison saw a string against `undefined` and reported drift on every
`mcp list` for any datamate-synced server — the feature cried wolf on
the exact servers it was built for.
Comparison is order-independent. `JSON.stringify` made `{a,b}` and
`{b,a}` look like drift, so equivalent `oauth`/`headersCommand` objects
were reported as differing.
Nested blocks are compared when EITHER side has one, not only when both
do. A server that gained or lost an `environment` wholesale used to
report the bare word "environment" and lose the key that actually
differs, which is the detail this function exists to provide. An empty
block against a missing one has no key to name, so that case still
reports the top-level field.
Drift is attributed to the file that actually defined the server rather
than to `sources.join(", ")`, which named every contributing file for
every drifted server and destroyed the "where to look" signal.
Drift and blank-variable warnings are cleared at the start of each
discovery run — a removed server or a resolved difference left a stale
entry that `mcp status` kept reporting — and they now survive the
nothing-to-list early return, where an enabled-only override for a
discovered server previously silenced them entirely.
Marker scoping fixed: the "per-field env-var resolution" block ran
unclosed to three stacked `altimate_change end` lines, swallowing the
#701 and #878 blocks. Marker Guard checks balance, not scoping, so this
passed CI while over-claiming unrelated code. They are siblings now.
Full opencode suite: 11503 pass. The two failures in that run
(`pty` ordering, `opencode run` subprocess) are pre-existing flakes —
both pass on isolated re-runs and neither file is touched here.

Follow-up to the previous commit on this PR, from the second review round.
Switching `_blankedEnv` from replace to union meant callers must clear
first, and two paths were not migrated:
* The well-known remote flow records the blanks it finds while
substituting `remote_config.url` and each header under the wellknown
URL, then hands the fetched body to `loadConfig` under that *same*
source — whose reset promptly deleted them. Those names were never
re-recorded, because the text `loadConfig` receives is already
substituted. `loadConfig` now takes `keepDiagnostics` and that nested
call sets it.
* `config/tui.ts` calls `substitute` directly with no paired reset.
Previously a clean parse self-healed via the `else delete` branch;
without it a `{env:VAR}` in tui.json that was later fixed would have
been reported blank for the life of the process. It resets now.
The staleness tests also mutated process-wide `process.env` without
saving what was there. They now capture and restore it in
`beforeEach`/`afterEach`, so a parallel `bun test` cannot observe a
variable this file removed or left behind.
Full opencode suite: 11489 pass, 0 fail.

…fix/mcp-status-drift
…Config Replaces the `keepDiagnostics` flag from the previous commit. That flag required widening `loadConfig`'s signature, and a modified signature line in an upstream-shared file cannot be wrapped in `altimate_change` markers in a form Marker Guard accepts — it flagged the line whatever the surrounding markers looked like. The signature is restored untouched. The reset now sits with the callers that actually begin a load: every file-based load via `loadFile`, `OPENCODE_CONFIG_CONTENT`, the console-managed config, and macOS managed preferences. The well-known remote flow is deliberately left out — it records the blanks found in `remote_config.url` and its headers under that same source before handing the fetched body to `loadConfig`, so a reset in there discarded them. Keeping the reset out of `loadConfig` makes that ordering explicit instead of encoding it in a flag. Behaviour is unchanged from the previous commit; this is about where the clearing lives and keeping the shared signature pristine. config/mcp suites: 458 pass, 0 fail.

SUGGESTION: _drift and _discoveredSource are process-wide singletons cleared at the top of the async discoverExternalMcp and repopulated across its await boundary — racy under concurrent discovery
resetConfigDrift() and _discoveredSource.clear() run before the first await, but _discoveredSource.set() (in addServersFromFile) runs only after several await readJsonSafe(...) calls, and _drift is repopulated by setConfigDrift in config.ts after this function returns. The comment above already contemplates "a daemon that discovers for a second project"; if two projects' config loads run discovery concurrently (two sessions in opencode serve), the clears/writes interleave, so one project's discoveredSource(name) can return the other project's file and resetConfigDrift() can wipe the other run's just-written drift. The configured value still wins, so this is only wrong diagnostic attribution — consider keying these maps by projectDir or serializing discovery if concurrent loads are possible.

Same missing spawnSync error guard flagged in PR 1159 mcp-env-diagnostics.test.ts — this is a copy-paste without that fix. spawnSync returns { status: null, error } on timeout or ENOENT rather than throwing. The output() helper swallows that silently, so spawn failure produces empty output and the first assertion fails as 'expected empty string to contain datamate' with no indication that the subprocess never ran. Same fix applies: check r.error and r.status === null before reading stdout/stderr, and throw a clear message.

There was a problem hiding this comment.
configDrift() is exported and read by reportConfigDiagnostics() in mcp list / mcp status, but prompt.ts's /mcps handler never calls it. A user debugging a silently-failing server via /mcps mid-session sees neither drift warnings here nor blankedEnvVars warnings (the latter flagged in PR #1159). Both diagnostic surfaces are supposed to solve the same 'why won't this server connect' problem, but the session command /mcps consistently receives only unresolvedEnvVars while the CLI surfaces the full picture. The pattern repeats with each new diagnostic type added, so the gap between CLI and session view will keep widening without an explicit design decision to sync them.
…eted
The reset in `loadFile` sat after `if (!text) return {}`, so a config
file that was deleted or emptied never cleared what it had recorded
while it still contained a `{env:VAR}`. `mcp list` and `/mcps` went on
warning about a variable that appears in no config at all. It runs at
the top of `loadFile` now, before the file is even read.
Three reviewers flagged this independently, and it is the third
placement mistake in this record — the reset landing after an early
return, inside the wrong function, or on a shared signature that cannot
be marked. The underlying reason is that `blankedEnvVars` had no test
coverage whatsoever, so nothing failed when the placement was wrong.
`test/config/blanked-env.test.ts` now pins the contract every call site
has to honour: substitution unions into a source, a later clean pass does
not erase an earlier finding, and only a reset clears. Mutation-tested —
restoring the old replace-semantics fails two of the five.
Full opencode suite: 11652 pass. The single failure in that run
(`pty` ordering) is the pre-existing flake; it passes on an isolated
re-run and no pty file is touched here.

…fix/mcp-status-drift
…rness
`/mcps` reported only the per-server unresolved variables from discovery,
while `mcp list` also reported file-scoped blanks. A server templated as
`"url": "https://{env:MY_HOST}/mcp"` records against the config file
rather than the server, so with `MY_HOST` unset the CLI named it and the
session view said nothing — and the session view is where someone is
when a server will not connect. The wording is extracted into
`formatBlankedEnvForDisplay` so it is testable without standing up a
session; `/mcps` is otherwise only reachable through the whole handler.
The subprocess harness moves to `test/cli/fixtures/isolated-cli.ts`. It
was duplicated verbatim across the MCP CLI tests, and the duplication was
not cosmetic — each copy carried the `bun run --cwd` bug, so fixing one
left the other reading the repo's own config instead of the temp project.
That harness also swallowed spawn failures. `spawnSync` does not throw on
ENOENT or timeout; it returns `{ status: null, error }` with null stdout,
so a subprocess that never ran surfaced as `expected '' to contain
'broken'` and read like a test-logic bug. It now says the subprocess did
not complete, and why.

…fix/mcp-status-drift
`configDrift()` was read by `mcp list` and `mcp status` but never by the `/mcps` session handler, so someone debugging a server mid-session saw neither drift nor the file-scoped blank variables the CLI reported. Both surfaces answer the same "why won't this server connect" question, and the session view is the one people are actually looking at. `/mcps` now renders drift through an exported `formatConfigDriftForDisplay`, testable without standing up a session, and the response is assembled from whichever of table/drift/blanks are non-empty. `mcp-status.test.ts` drops its verbatim copy of the subprocess harness in favour of `test/cli/fixtures/isolated-cli.ts`, which also carries the `spawnSync` guard — the copy here had neither, so a spawn failure showed up as `expected '' to contain 'datamate'` with no hint the CLI never ran. Full opencode suite: 11675 pass. The single failure in that run (`opencode run` subprocess) is the known flake — `test/cli/run` and `test/session` pass 927/0 in isolation, and the failing set varies between runs.

SUGGESTION: New #878/#701 marker blocks are nested inside the #972 "shared text formatter" block, and the /** @internal Exported for tests. */ docstring is left dangling above formatConfigDriftForDisplay
The #972 block previously contained only formatMcpStatusForDisplay, whose /** @internal Exported for tests. */ docstring sat directly above it. This diff inserts the #878 and #701 blocks between the #972 opening marker (line 2900) and that function, so both are nested inside it — the same over-scoping Marker Guard checks presence but not correctness for (cf. the #878 block in discover.ts). The docstring now sits above formatConfigDriftForDisplay, which already has its own /** Config-drift lines ... */, leaving formatMcpStatusForDisplay undocumented. Close the #972 block after its docstring and place the new blocks as siblings.

Add teardown for the module-level drift store.
setConfigDrift mutates shared module state. beforeEach only resets state before a test. Add afterEach(resetConfigDrift) so each test restores the store after completion or failure.
Proposed fix
-import { describe, expect, test, beforeEach } from "bun:test"
+import { describe, expect, test, beforeEach, afterEach } from "bun:test"
describe("configDrift record", () => {
beforeEach(() => resetConfigDrift())
+ afterEach(() => resetConfigDrift())As per coding guidelines, tests using shared state “must provide teardown and isolation safe for parallel bun test execution.”

What does this PR do?
1. Adds
mcp status(#790).statusis the name people reach for when a server won't connect, and it was the one name that didn't exist.Being straight about the size of this: the gap was narrower than the issue implies.
mcp listalready probed live (mcp.status()initialises the MCP service) and already printed the failure reason. The missing piece was the entry point, not the view — sostatusshares that handler rather than duplicating a view that would then need keeping in sync.It's a sibling command rather than an alias because
aliases: ["ls", "status"]widened yargs' alias column enough to rewrap an unrelated row (mcp auth listlost its[aliases: ls]onto a second line). As its own command the help output stays additive — the diff against the committed snapshot is exactly one added line.2. Reports discovered-config drift (#878). Discovery is first-source-wins, so a server already in the user's config is skipped outright, and a changed
.vscode/mcp.json— a newALTIMATE_EXTENSION_RPCport, a moved command — was never mentioned.driftFields()now reports which fields disagree, naming nested keys individually (environment.ALTIMATE_EXTENSION_RPC) so the message points at the thing to fix rather than justenvironment.enabledis excluded, since discovery sets it for its own reasons.The configured value still wins. This reports the disagreement and where to look, and leaves the decision to the user — silently overwriting someone's own config would be worse than the silence it replaces. That's the "detect and report" option of the three the issue offered.
How did you verify your code works?
opencodesuite: no regressions.HOMEplus a temp project containing a drifted.vscode/mcp.json, asserting both that the drifted field is named and that an agreeing config stays silent.statusregistration, each fails exactly one test.origin/main; typecheck clean.Flaky tests, flagged rather than hidden: the subprocess-heavy suites (
test/pty,test/cli/run) fail intermittently under parallel load — different tests each run, all passing across repeated isolated runs. These flakes pre-date this PR, but it does make them more likely to surface: it adds two more e2e files that each spawn real CLI subprocesses.Test-harness fix worth knowing about: the e2e pattern copied from
mcp-add.test.tsusesbun run --cwd <pkg>, which makes the CLI's working directory the repo package — so it read the repo's own.opencodeconfig and never saw the temp project, meaning discovery never ran and the drift assertion couldn't fire. Fixed here by setting the spawn cwd to the project.mcp-add.test.tsis unaffected in practice (it passes--global), so it's left alone.Screenshots / recordings
Not a UI change.
