* url elicitation
* single tool for normal and error path
* Address review feedback on URL elicitation tool
- Remove src/everything/pnpm-lock.yaml (monorepo uses npm workspaces)
- Drop redundant TriggerUrlElicitationSchema.parse(args) in the handler;
destructure directly from args like the other tools, since the SDK
validates against the registered schema before invoking the handler
- Add explicit accept/decline/cancel messaging in the request path,
mirroring trigger-elicitation-request.ts
- Clarify the registerTool count comment in registrations.test.ts
(task-based tools register via registerToolTask, counted separately)
- Add tests covering the no-url / undefined-capability registration
guards, the randomUUID() elicitationId fallback, and the
decline/cancel response paths (100% coverage of the tool)

* Add tool annotations to trigger-url-elicitation
Match the annotations block on sibling elicitation tools and the
CLAUDE.md guidance. Uses openWorldHint: true since the tool drives an
external browser flow.

* fix(everything): prevent URL elicitation error-path infinite loop
The trigger-url-elicitation tool's error path (errorPath=true) threw
UrlElicitationRequiredError (-32042) carrying the same URL that failed and
re-threw it on every retry, so clients looped (and tripped their own loop
detection).
- Point the prerequisite elicitation at a different URL
(https://modelcontextprotocol.io) than the failing request.
- Track issued prerequisites by the inputs a client resends on retry
(session + url + caller-supplied elicitationId); a plain retry is then
recognized, ignores errorPath, and proceeds via the request path instead
of re-throwing the prerequisite.
- Update tests and docs accordingly.

* fix(everything): address review on URL elicitation error path
- Replace raw NUL byte delimiters in errorPathKey with the \u0000 escape
sequence so the source stays plain text and the diff is reviewable
(same collision-proof delimiter at runtime).
- Add a one-shot test reset helper + beforeEach so the suite is robust to
the module-level marker state regardless of order.
- Use a dedicated prerequisite message instead of reusing the caller's.
- Document the unbounded-growth tradeoff as a demo simplification and note
the one-shot marker semantics in docs/features.md.

"Everything Server crashes when multiple clients reconnect"
* In index.ts
- added a variable to hold the initialize timeout
- store the timeout in the oninitialized handler
- clear the timeout in the cleanup callback
* In roots.ts
- In the catch block of syncRoots, log the error to the console via .error rather than attempting to send to the client because the most probable case here is that we don't have a connection.
* In simulate-research-query.ts
- remove redundant local variable in getTask
* Everywhere else, prettier.
Update documentation to reflect that simulate-research-query now sends
elicitation requests directly from the background task instead of using
the tasks/result side-channel approach.

Add tools that demonstrate bidirectional MCP tasks where the server
sends requests to the client for async execution:
- trigger-sampling-request-async: Send sampling request with task
params, client creates task and executes LLM call in background,
server polls for completion and retrieves result
- trigger-elicitation-request-async: Same pattern for user input,
useful when user may take time to fill out forms
Both tools:
- Check client capabilities (tasks.requests.sampling/elicitation)
- Accept both CreateTaskResult and direct result responses
- Poll tasks/get for status updates
- Fetch final result via tasks/result
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
- Add tasks capability with list, cancel, and requests.tools.call
- Add InMemoryTaskStore and InMemoryTaskMessageQueue from SDK experimental
- Add simulate-research-query tool demonstrating task lifecycle
- Task demonstrates working -> input_required -> completed status flow
- Uses elicitation for ambiguous queries when client supports it
Closes#3037🦉 Generated with [Claude Code](https://claude.ai/code)
Finalized Roots list changed handling and initial request. Final fit and finish work.
* Updated architecture.md
- Added links to other docs
- Refactor/extracted sections into extension.md, features.md, how-it-works.md, startup.md, and structure.md
* Removed everything.ts
- all features are ported
* In roots.ts
- refactor/renaned setRootsListChangedHandler to syncRoots
- refactor handler logic to requestRoots function
- Calls for roots list directly to get initial list
* In server/index.ts
- import setRootsListChangedHandler
- in clientConnected callback
- call setRootsListChangedHandler passing server and sessionId
* In sse.ts, stdio.ts, and streamableHttp.ts
- update inline and function docs
* In index.ts,
- updated usage output
* In server/index.ts
- refactor/extracted readInstructions to resources/index.ts
- defined ServerFactoryResponse response type
