- add .idea/ for Jetbrains IDEs
* in everything.ts
- remove import of SetLevelRequestSchema
- remove logLevel var
- add sessionId var
- in startNotificationIntervals function
- add optional sid argument
- set sessionId to sid
- define messages to be sent, adding sessionId if present
- remove setRequestHandler call for SetLevelRequestSchema
- replace server.notification calls that sent "notifications/message" objects with calls to server.sendLoggingMessage, passing just the parameters and sessionId.
* In package.json & package-lock.json
- bump TS SDK version to 1.17.5
* In sse.ts, pass transport.sessionId to startNotificationIntervals call
* In stdio.ts
- destructure startNotificationIntervals from createServer call
- implement custom logging request handler and server.sendLoggingMessage implementation, as a
workaround for the fact that the SDK's automatic log level handling currently only tracks requested log level by session id. This will be fixed in a followup PR for the SDK
- call the startNotificationIntervals function after connecting the transport to the server
* In streamableHttp.ts
- destructure startNotificationIntervals from createServer call
- call startNotificationIntervals passing the transport.sessionId after connecting the transport to the server
For both sse and streamableHttp, a server instance needs to be created for each transport. Otherwise, when a new client connects and its new transport is connected to the single server, the previous transport is overwritten in the server instance and can no longer communicate.
* In sse.ts
- remove global server, cleanup, and transport vars
- add transports map
- in sse GET handler,
- check for sessionId, there shouldn't be one, so comment "Reconnecting?" and do nothing if present
- if sessionId not present
- create new server and transport instance
- connect server to transport
- add transport to transports map
- in server.onclose, delete the transport from the transports map and call cleanup
- in /message POST handler
- get the sessionId from the request
- get the transport from the map by sessionId
- handle the message if the transport was found
* In streamableHttp.ts
- remove the global server and cleanup vars
- change transports var to Map
- in /mcp POST handler
- when creating a new session
- create a server instance
- in server.onclose, delete the transport from the transports map and call cleanup
- remove the calls to cleanup and server.close in the SIGINT handler, because the transport is closed and its onclose handler closes the server.
- Replace console.log with console.error throughout
* In src/everything/sse.ts
- remove the process.exit() in the server.onclose handler so reconnections are possible
# Run the default (stdio) server
```npx @modelcontextprotocol/server-everything```
# Or specify stdio explicitly
```npx @modelcontextprotocol/server-everything stdio```
# Run the SSE server
```npx @modelcontextprotocol/server-everything sse```
# Run the streamable HTTP server
```npx @modelcontextprotocol/server-everything streamableHttp```
* In src/everything/index.ts
- refactor/extracted contents to stdio.ts
- replaced with code that
- Gets the single argument from the commandline as scriptName
- switches on scriptName
- imports the appropriate server script or outputs usage options
- scripts run on import
* In src/everything/stdio.ts
- added console log "Starting default (STDIO) server..."
* In src/everything/sse.ts
- added console log "Starting SSE server..."
* In src/everything/streamableHttp.ts
- added console log "Starting Streamable HTTP server..."
* This fixes#1594
