The syncRoots call should be idempotent, requesting roots if they haven't been yet for the session, but always retuning the cached roots otherwise. That could be deferred but setting the handler for roots_list changed note should not.
* In server/roots.ts
- only set the notification handler and call for initial roots list if the roots aren't already cached for this client.
* In server/index.ts
- in the oninitialized handler
- get the sessionId from the transport
- set a 350ms timeout to call syncRoots with the server and sessionId
- this delay cause it to run after the `notifications/initialized` handler finishes, otherwise, the request gets lost.
* All other changes attributable to prettier
* In server/roots.ts
- in syncRoots, if roots are supported fetch them
* In get-roots-list.ts,
- Don't import and inspect current roots map, just call syncRoots to get the list.
* In how-it-works.md,
- added a section on conditional tool registration
* In server/index.ts
- import registerConditionalTools
- in an oninitialized handler for the server, call registerConditionalTools
- removed clientConnected from ServerFactoryResponse and all mentions in docs
* In tools/index.ts
- export a registerConditionalTools function
- refactor/move calls to registerGetRootsListTool, registerTriggerElicitationRequestTool, and registerTriggerSamplingRequestTool out of registerTools and into registerConditionalTools
* In server/roots.ts
- only act if client supports roots
- remove setInterval from call to requestRoots. It isn't happening during the initialze handshake anymore, so it doesn't interfere with that process if called immediaately
* In get-roots-list.ts, trigger-elicitation-request.ts, and trigger-sampling-request.ts,
- only register tool if client supports capability
* Throughout the rest of the files, removing all references to `clientConnected`
* In get-roots-list.ts, query the server's cache of the latest roots from the client and only request the list from the client if it doesn't exist.
* In roots.ts, export the roots map
* In get-roots-list.ts, query the server's cache of the latest roots from the client and only request the list from the client if it doesn't exist.
* In roots.ts, export the roots map
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
Adding Trigger Elicitation Request and Get Roots List tools
* Updated architecture.md
* Added roots.ts
- tracks roots by sessionId
- setRootsListChangedHandler
- listens for roots changed notification from the client
- updates the roots map by sessionId
- sends log notification or error to the client
* In server/index.ts
- import setRootsListChangedHandler
- in clientConnected callback
- call setRootsListChangedHandler passing server and sessionId
* In sse.ts, stdio.ts, and streamableHttp.ts
- receive clientConnected from server factory
- call clientConnected when server is connected to transport
* Added get-roots-list.ts
- registerGetRootsListTool
- Registers the 'get-roots-list' tool with the given MCP server.
* Added trigger-elicitation-request.ts
- registerTriggerElicitationRequestTool
- registered tool sends an elicitation request that exercises all supported field types
* In tools/index.ts
- imports registerTriggerElicitationRequestTool and registerGetRootsListTool
- in registerTools
- call registerTriggerElicitationRequestTool and registerGetRootsListTool, passing server
