Problem

Fixes #28568.

A claude.ai connector that once failed its sign-in stays unavailable in every new Claude thread for up to 4 hours, even after the user reconnects it on claude.ai. Claude Code records the failure in ~/.claude/mcp-needs-auth-cache.json, and each new process skips that connector without dialing it until the entry expires. So the supported recovery path, a new thread or Stop and resend, does not work for claude.ai connectors.

Change

On the first system/init of each Claude process, the adapter calls the SDK's reconnectMcpServer for every claude.ai connector (source: "claudeai") reported as needs-auth. A reconnect dials the connector for real. When the dial succeeds, Claude Code connects it and removes the cache entry. When it doesn't, the error is ignored and the connector stays needs-auth, as it is today. The calls run in the background in the session scope, so turn start is not delayed.

  • New processes only. Later turns in the same process do nothing new. Mid-session reconnect stays out of scope, as decided in #19471.
  • Rate limit. Each connector is retried at most once a minute per provider instance. mcpServerStatus reports a cache-skipped connector exactly like one the user never authorized, so every attempt also dials the unauthorized ones. In my setup that was 15 extra dials, about 25 s of background work.
  • Closing a process. Closing a Claude query, or the process exiting on its own, interrupts its unfinished reconnects, and an interrupted attempt does not hold the cooldown. Without this, Stop-and-resend within the minute would skip a connector whose dial was cut short.
  • Plumbing. ClaudeAgentSdkQuerySession gains reconnectMcpServer, with a protocol-log frame written before the call. Replay transcripts never record these background reconnects, so the replay fake and the other test fakes treat it as a no-op.
  • Old CLIs. CLIs whose init has no source field are left alone. The existing replay fixture with a sourceless claude.ai needs-auth server replays unchanged.

Scope and approval

This is a focused bug fix. The new-process path is the one maintainers named as supported in #19471, and here it fails for claude.ai connectors. Nothing is added to the UI, contracts or settings, and in-session reconnect is not added.

Verification

Test. I added reconnects claude.ai connectors needing auth when a Claude process starts, at most once per cooldown to ClaudeAdapterV2.test.ts. It runs three Claude processes on one thread and checks:

  1. The first init reconnects only the claude.ai needs-auth connectors. It skips connected ones, non-claude.ai ones, and ones with no source.
  2. A later init in the same process reconnects nothing.
  3. A new process within a minute reconnects only a connector it hasn't tried yet.
  4. After a minute, the stuck connectors are retried.
  5. A reconnect cut short by closing its process, or by the process exiting on its own, is retried by the next process within the minute.

I checked that the test fails for each way the code could be wrong:

Related suites. ClaudeAdapterV2.test.ts, ClaudeReplayFixtures, OrchestratorReplayRecovery, OrchestratorReplayRestartBackgroundNote, ThreadFork, ThreadMergeBack and ClaudeAutomaticDelivery integration tests: 343/343 pass after merging main.

vp run check:changed. Format, lint, knip and tests pass. Typecheck reports 45 errors locally, in src/cli/*.test.ts, src/preview/ServerBrowserStream*, binCli.ts, HostPowerMonitor.ts and NativeTelemetryClient.ts. A clean main checkout gives the same 45 errors here, and none are in the files this PR changes.

Runtime check. I ran Claude Code CLI 2.1.316 through the bundled Agent SDK, with no model turn, on a machine where claude.ai Sentry was stuck in the cache:

1mcpServerStatus() -> claude.ai Sentry: needs-auth (cache entry present)
2reconnectMcpServer("claude.ai Sentry") -> resolved in ~1.5 s
3mcpServerStatus() -> claude.ai Sentry: connected, 14 tools
4~/.claude/mcp-needs-auth-cache.json -> entry for "claude.ai Sentry" removed

T3's own provider logs from the failing threads show that the first system/init of a new process already lists the claude.ai connectors with their status: claude.ai in init: 28 {pending: 8, needs-auth: 20} Sentry: needs-auth. That is why the first init works as the trigger.

Not checked. I did not run a live Claude turn through a vp run dev server with this branch. The path is covered by the adapter test above and by the SDK-level check against the real CLI.

Approvability

Verdict: Approved at 6f4e909

Macroscope's review found this PR approvable — New Claude processes retry existing claude.ai connectors stuck needing authentication, with a one-minute cooldown per connector. The recovery is scoped, runs in the background, and leaves other connector types and authorization policy unchanged.

Walkthrough

ClaudeAdapterV2 now requests reconnects for eligible Claude.ai MCP servers when a process initializes. The query session delegates reconnect requests to the SDK. Attempts use a 60-second per-server cooldown, and query shutdown or message-stream exit interrupts pending reconnects.

Merge Risk: External image Minimal · previous review 49a91

This change reconnects claude.ai connectors stuck as needing auth when a new Claude process starts. The reconnects run in the background, are rate-limited, and are interrupted when the process closes. No merge-blocking risk remains. The first turn may start before a slow reconnect finishes, which is an intended tradeoff of the background design.

Full details: Title check

Explanation

The title names the main change: new Claude sessions reconnect claude.ai connectors that are stuck in needs-auth. The changeset adds a reconnectMcpServer call on the first system/init of each Claude process for claude.ai needs-auth connectors, so the title matches the primary change. It uses a conventional commit format and is specific.

Full details: Linked Issues check

Explanation

The changes satisfy the coding requirements in [#28568]. On the first system/init for each Claude process, the adapter selects only source === "claudeai" servers with status === "needs-auth". It calls reconnectMcpServer in the session scope. A 60-second per-server cooldown limits retries. Later init frames do not trigger retries. Query close and stream exit interrupt pending reconnects and remove their cooldown entries. The focused test covers filtering, process boundaries, cooldowns, and interrupted retries. The SDK session logs the reconnect request before the call, and replay support uses a no-op implementation.

Full details: Out of Scope Changes check

Explanation

The changes stay within [#28568]. The protocol-log event, SDK session method, replay no-op, test fakes, and focused test support the new-process reconnect path. The changes add no UI, settings, contract, or mid-session reconnect behavior. The sourceless init case remains unselected.

Full details: Description check

Explanation

The description covers the problem, change, scope and approval basis, and verification. It reports focused tests and related suite results, identifies typecheck errors also present on main, and states that a live Claude turn was not tested. It also names the model and harness used.

Log reconnect requests before the SDK call and serialize reconnect effects.

Effect.tap logs only after queryRuntime.reconnectMcpServer(serverName) succeeds. A rejected reconnect is ignored by the caller, so its outbound frame is absent from the recorded transcript. Replay still calls assertNextOutboundFrame for that reconnect and can fail on the next frame.

Pre-logging alone does not guarantee order while reconnects run with unbounded concurrency. Log before the SDK call and serialize the reconnect effects.

Note

🤖 Claude Opus 5.5 responding on behalf of khaledDiZ

Partly applied in f299c3a7: the log now happens before the SDK call, the replay fake no longer expects a frame, and the reconnects stay parallel.

  • Log before the call: applied. Most attempts are expected to fail, and they should still appear in the provider log.
  • Replay: the hazard is real, but not via the protocol log. Replay transcripts are not built from the protocol log. recordClaudeAgentSdkReplayTranscript drives the SDK directly and writes its own expect_outbound entries, so it never records these background reconnects. The real problem was the replay fake asserting a query.reconnect_mcp_server frame. I checked it: adding "source":"claudeai" to the claude.ai Google Drive needs-auth server in thread_fork_native_fork_local_rollback, as a current CLI records it, made ThreadFork.integration.test.ts fail with ClaudeReplayFrameMismatchError on the previous commit. With the fake now a no-op, it passes 4/4.
  • concurrency: 1: not applied. These reconnects run in the background, alongside the turn's other outbound frames, so serializing them would not make the order deterministic. It would make a stuck connector wait behind every unauthorized one. In my setup that was 15 failing dials, about 25 s of work in parallel. No test or replay asserts the order of these reconnects.
CcoderabbitaiBot12d ago

@khaledDiZ Thanks for the correction. I conflated the provider protocol log with the replay recorder.

  • The supplied code now logs query.reconnect_mcp_server before the SDK call. This preserves visibility when a reconnect fails.
  • Your recorder explanation identifies the replay mismatch correctly: the fake expected a frame that the recorder did not produce. Making that operation a no-op addresses that mismatch.
  • I withdraw the concurrency: 1 recommendation. Serializing reconnects would not establish ordering against other outbound operations. It would also delay later connectors behind slow attempts.

No further change is needed for this finding. I have not independently rerun the reported 4/4 integration tests.

Outside diff Cancel reconnect work when its Claude query closes.

10392-10398: External image Minor · Functional Correctness · Quick win

Cancel reconnect work when its Claude query closes.

The first system/init records the connector in the adapter-wide cooldown map before starting the reconnect fiber. The fiber belongs to sessionScope, so replacing the process closes the old query but does not cancel the fiber. The fiber can call reconnectMcpServer on the closed query, and the ignored failure consumes the 60-second cooldown. A replacement process during that interval skips the reconnect, so the connector can remain in needs-auth.

Tie the reconnect fiber to the individual query and cancel it when that query closes. Only record the cooldown for an attempt that belongs to the current query.

Note

🤖 Claude Opus 5.5 responding on behalf of khaledDiZ

@coderabbitai Your follow-up finding was valid ("Cancel reconnect work when its Claude query closes"). It is fixed in 828cba8a.

  • Closing a Claude query now interrupts its unfinished connector reconnects before the process closes.
  • An interrupted attempt removes its cooldown entry, so the next process dials that connector again. Attempts that finished, whether they succeeded or failed, still hold the cooldown.
  • The adapter test now runs a fourth process. Sentry's reconnect is still dialing when process 3 closes, and process 4 is expected to retry it within the minute. The test fails if either half of the fix is removed.

Branch merged with main in 9b85fe86. The only conflict was the result-ledger block that sits next to the init handling, and both blocks are kept.

Cancel reconnects when the query stream ends.

connectorReconnects is interrupted only by querySession.close. The query-stream exit path finalizes state and resolves closed, but does not interrupt the reconnect fiber. Because both effects run in sessionScope, a terminated stream can leave the reconnect pending and keep its 60-second cooldown active. Add the same interruption cleanup to the stream-exit path.

Valid, and fixed in 05f8e607. If the Claude CLI exited by itself, only an explicit close interrupted the reconnects, so they stayed pending and held the cooldown. The query stream's exit handler now runs the same interrupt first, before it finalizes the turn and resolves closed. The adapter test now ends the fourth process's stream without close and checks that the fifth process retries the stuck connector. The test fails without this line.

@khaledDiZ The supplied code confirms that the query-stream exit handler now calls stopConnectorReconnects before turn finalization and resolution of closed. This addresses the pending reconnect and cooldown issue when the CLI exits without an explicit close.

@khaledDiZ Thanks for the fix in 828cba8a. The reported behavior addresses both parts of the finding: query close interrupts unfinished reconnects, and interrupted attempts release their cooldown entries. Completed attempts retain their cooldown.

The fourth-process regression test covers the retry after interruption. I have not independently verified the merged revision.

Merged current main again (merge commit 926240f521, no rebase) to clear a new conflict in ClaudeAdapterV2.

  • Main started recording claude_code_version on the first init. The resolved block keeps that and this PR's processInit narrowing: context.claudeCodeVersion = processInit.claude_code_version.
  • d4fa22cbc1 adds the reconnectMcpServer no-op to a test fake main added since the last merge.

No behavior change to the fix. vp run check:changed passes (format, lint, knip, typecheck, 361 tests in ClaudeAdapterV2, ClaudeAutomaticDelivery and AgentContextBudget). All review threads were already resolved.

Verified in a real dev environment

Head d4fa22cbc1, vp run dev on Linux, web client driven with Playwright and Chrome. Project: a local git repo added through "Add project > Local folder". Provider: Claude Code CLI 2.1.322, model Claude Haiku 5.5, real turns.

  • First turn in a new Claude process works. "Reply with exactly the word: pong" returned pong. The process's first system/init reports mcp_servers: [{computer, connected, source: "user"}, {t3-code, connected, source: "dynamic"}], so CLI 2.1.322 does send the source field this PR filters on.
  • No reconnects for connectors that are not claude.ai. The provider protocol log has no query.reconnect_mcp_server frame across 7 init messages and 2 processes. That is correct here because no server has source: "claudeai".
  • Follow-up turn in the same process works. "second" was answered with no new process and no reconnect.
  • Stop and resend still work. This path goes through the PR's wrapped close and stream-exit stopConnectorReconnects. I stopped a turn 10 s into a 90 s Bash command. The log shows query.interrupt and query.close, and the UI shows "Run interrupted · Stopped by user". The resent message opened a second process (query.open ×2) and replied resumed. The server log has no errors or defects.

First Claude Haiku 5.5 turn on the PR head: pong reply

After Stop on a running Bash tool call and a resend: Run interrupted, then resumed reply

Recording of the stop and resend: https://uploads-production-47e4.up.railway.app/files/bc87fe49-8e2b-440b-a947-77821817224d/stop-resend.mp4

Not verified

  • The fix itself. This VM's Claude login is an OAuth token through a proxy with no claude.ai account connectors. init lists no source: "claudeai" servers, so I could not reproduce a connector stuck in ~/.claude/mcp-needs-auth-cache.json, on main or on this head. Untested paths: a real reconnectMcpServer dial, cache-entry removal, the 1-minute cooldown, and interrupt-releases-cooldown against a live connector. Those are covered only by the PR's adapter test and the author's SDK-level check.
  • Desktop and mobile clients. The change is server-only and was exercised through the web client.

The automated pipeline stopped on this pull request and will not merge it:

the fix is written and reviewed, but proving it needs something no worker has:

  • Permanent blocker: A first-party Claude OAuth account with a claude.ai connector whose authorization has lapsed is required and is explicitly unavailable on this VM. Therefore cached needs-auth behavior on base and restoration of connector tools after external reauthentication on head could not be demonstrated.
  • Background reconnect, the one-minute retry cooldown, and reconnect cancellation when a process stops were not demonstrated in the real app.

It stays open for a person to finish or close.
