I’m a rabbit checking reports with care,
I wait ten seconds, then poll the status there.
If issues are ready, I hop along,
If work continues, I note what’s still going on.
The next page needs no pause from me,
I nibble a carrot and bound off free.

Stop polling when the MCP request is canceled.
fetchAccessibilityIssues receives the MCP cancellation signal, but waitForProcessing does not use it. After cancellation, the polling delay can still complete and trigger repeated reportFetcher.reportStatus(source) calls for up to five minutes. Pass the signal to waitForProcessing, reject its delay when the signal aborts, and check the signal before each status request.
One status request can still finish after cancellation because apiClient does not support abort signals. This localized fix prevents subsequent polling requests without changing that transport.

<excerpt>citeturn1search0 [wordlim: 200] Crawled: 2 weeks ago; None of the three takes type parameters — v1's `RequestHandlerExtra<TRequest, TNotification>` arguments selected request/notification unions that the v2 context carries intrinsically, so their removal loses no type information; review only handlers that passed custom (non-standard) unions, whose `sendRequest` / `sendNotification` typing was narrowed by them. ... import { CreateMessageResultSchema } from '@modelcontextprotocol/sdk/types.js';
### Low-level protocol & handler context (`ctx`)
The second parameter to every request handler — previously the flat `RequestHandlerExtra` object named `extra` — is now a structured context object named `ctx`. This is the `ctx` that appears throughout the rest of this guide.
The codemod renames the parameter and remaps property access via `contextPropertyMap.ts`. A few mappings need optional-chaining adjustment (the `http` group is `undefined` on stdio):
v1 (`extra.*`) | v2 (`ctx.*`) | Note
--- | --- | ---
`extra.signal` | `ctx.mcpReq.signal` |
`extra.requestId` | `ctx.mcpReq.id` |
`extra._meta` | `ctx.mcpReq._meta` |
`extra.sendRequest(...)` | `ctx.mcpReq.send(...)` |
`extra.sendNotification(...)` | `ctx.mcpReq.notify(...)` |
`extra.sessionId` | `ctx.sessionId` |
`extra.authInfo` | `ctx.http?.authInfo` | optional — `undefined` on stdio
`extra.requestInfo` | `ctx.http?.req` | a standard Web `Request`; `ServerContext` only
`extra.closeSSEStream` | `ctx.http?.closeSSE` | `ServerContext` only; the member itself is also optional — defined only when the transport has an `eventStore` AND the client's negotiated protocol version supports resumable close (2025-11-25+); an `eventStore` transport serving a 2025-06-18 client still leaves it `undefined`. Call as `ctx.http?.closeSSE?.()`
`extra.closeStandaloneSSEStream` | `ctx.http?.closeStandaloneSSE` | `ServerContext` only; member optional as above — `ctx.http?.closeStandaloneSSE?.()`
`extra.taskStore` / `taskId` / `taskRequestedTtl` | removed | see Experimental tasks
The transport-level seam behind `ctx.http?.authInfo` is unchanged from v1: a transport that passes `{ authInfo }` as the second argument to `onmessage(message, extra)` — e.g. an `InMemoryTransport` test seam — still surfaces it as `ctx.http?.authInfo` on any transport, and `ctx.http` is defined whenever `authInfo` is supplied, even without an HTTP transport.
`BaseContext` is the common base; `ServerContext` and `ClientContext` extend it. None of the three takes type parameters — v1's `RequestHandlerExtra<TRequest, TNotification>` arguments selected request/notification unions that the v2 context carries intrinsically, so their removal loses no type information; review only handlers that passed custom (non-standard) unions, whose `sendRequest` / `sendNotification` typing was narrowed by them. `ServerContext.mcpReq` adds convenience methods that replace calling `server.*` from inside a handler:
`ctx.mcpReq.*` (new) | Replaces (inside a handler)
--- | ---
`ctx.mcpReq.log(level, data, logger?)` | `server.sendLoggingMessage(...)` — ⚠ `@deprecated`, see §Deprecated in v2; the notification also becomes request-related on every era — see §`ctx.mcpReq.log()` is request-related on every era
`ctx.mcpReq.elicitInput(params, options?)` | `server.elicitInput(...)`
`ctx.mcpReq.requestSampling(params, options?)` | `server.createMessage(...)` — ⚠ `@deprecated`, see §Deprecated in v2
#### Deprecated in v2 (SEP-2577)
The roots, sampling, and logging subsystems are deprecated as of protocol version 2026-07-28 (SEP-2577). Everything below is still fully functional in v2 and marked `@deprecated` for removal in a later major; on a 2026-07-28 connection prefer the multi-round-trip `input_required` pattern instead.

<excerpt>citeturn0search0 [wordlim: 200] Published: 8 months ago; Crawled: 3 weeks ago; @modelcontextprotocol/sdk (npm) ... In-flight request handler abort controllers are cleaned up on `close()`, and `sendNotification`/`sendRequest` in handler extras check the abort signal before sending, preventing messages from leaking after a transport is replaced
What is affected: This depends on what features your server uses:
* Final responses (the return value from a tool/resource/prompt handler): Affected in most cases. The Protocol captures this._transport at request-handling time, not the transport that delivered the request. This means:
* If a request is already in-flight when a second connect() occurs (i.e., the request
arrived before the transport was overwritten), the captured reference is correct and
the response routes properly.
* If a request arrives on the old transport after a second connect() has overwritten
this._transport, the captured reference points to the new transport, and the response
is mis-routed. The requesting client will time out.
* Progress notifications sent during tool execution via `sendNotification`: Affected. These are dispatched through `this._transport`. When the transport has been overwritten and message IDs collide on the new transport, notifications are routed to the wrong client's HTTP stream.
* Sampling (`createMessage`) and elicitation requests sent during tool execution via `sendRequest`: Affected. * You are in stateless mode and reuse both a transport and a server across requests → affected by both issues; all request types can leak.
* You are in stateless mode and create a new transport per request, but reuse the server → affected by Issue 2 only; safe if your tools only return results without sending progress notifications, sampling, or elicitation during execution.
* You create a new server + transport per request → not affected.
* Single-client environments (e.g., local development with one IDE) → not affected.
### Patches
The fix (v1.26.0) adds runtime guards that turn silent data misrouting into immediate, actionable errors:
1. `Protocol.connect()` now throws if the protocol is already connected to a transport, preventing silent transport overwriting (addresses Issue 2)
2. Stateless `StreamableHTTPServerTransport.handleRequest()` now throws if called more than once, enforcing one-request-per-transport in stateless mode (addresses Issue 1)
3. In-flight request handler abort controllers are cleaned up on `close()`, and `sendNotification`/`sendRequest` in handler extras check the abort signal before sending, preventing messages from leaking after a transport is replaced

### Summary
In v2, `Protocol.setRequestHandler` / `setNotificationHandler` require a method-string literal as the first argument and no longer accept the request/notification Zod schema object (the v1 API). Two consequences motivated this request while migrating a client:
1. v1-peer libraries break at runtime with a confusing error. Any library still on the v1 peer that calls `client.setNotificationHandler(SomeNotificationSchema, handler)` now throws:
`'[object Object]' is not a spec notification method; pass schemas as the second argument to setNotificationHandler()

Treat progress notifications as best effort.
When context.sendNotification rejects, waitForProcessing propagates the rejection before getReportLink or CSV parsing. The outer handler converts it to an error response, so the rejection does not escape, but available issues are not returned.

Update waitForProcessing so failures from notifyScanProgress are caught and
ignored as best-effort progress delivery, allowing report retrieval and CSV
parsing to continue. Keep the existing notification message, progress
calculation, polling, and returned ProcessingState behavior unchanged.

…ading its issues
An agent that fetched an SDK build's issues right after the test run got 14
issues, called final ("All issues retrieved"); the build completed minutes
later with 27. After the tests end a build stays "finalizing" (advanced
issue processing, for an advanced scan) and the export serves whatever
exists so far.
fetchAccessibilityIssues now reads the report's status first: a scan run's
status endpoint, a Workflow Analyzer report's summary, and for a build its
project's build list, since the build overview carries no status. While it
is queued, running, processing or finalizing, a first read waits, polling
every 10 s for up to 5 min with progress notifications, then reads the
issues and says it waited. If processing outlasts the wait, the answer
says the issues are only those found so far and to fetch again, instead of
"All issues retrieved". A later page does not wait again, and a status
that cannot be read is not waited on.

… its tests run
A build whose suite is still running can take as long as the suite; blocking the first
read for five minutes and then returning partial results anyway serves nobody. The wait
now covers only the post-run advanced-issue processing ("finalizing"), which ends
within minutes. A run in progress is read as it is, with the note that the issues are
those found so far.

An agent that fetched an SDK build's accessibility issues right after the test run reported 14 issues as final ("✅ All issues retrieved"). The build completed minutes later with 27. After the tests end, a build stays
finalizing, which on an advanced scan is the dashboard's "advanced issue processing", and the export serves whatever exists so far.Recorded on a fresh build, polling every 5 s:

fetchAccessibilityIssuesreads the report's status before reading its issues:GET …/scans/{id}/scan_runs/{run}/statusGET …/reports/{id}→summary.statuslist_buildsrow (the build overview has no status), found by id in the newest buildsqueued/running/processing/finalizing), a first read waits: it polls every 10 s for up to 5 min, the same budgetstartAccessibilityScanuses, and sends progress notifications. Then it reads the issues and says it waited.Verification
Ran a fresh SDK test (accessibility + advanced on) and called this branch's build over MCP the moment the run ended:
Without this change the same call returns 14. New tests cover each source's status read (including a build found on the second page of its project's list, and an unreadable status), no wait when complete, waiting through
finalizing(fake timers), the warning when processing outlasts the wait, no wait on later pages, and progress notifications.npm run build(lint, format, 1336 tests, tsc) passes.API follow-up (optional): the Automated Tests build overview (
GET /api/automated-tests/v1/builds/{id}) has nostatus, so the MCP reads it from the project's build list.get_build_summaryalready holds the TestHub objectlist_buildstakes it from, so adding it there is one line and would make this a single call.🤖 Generated with Claude Code
