Summary

AI summary

Fixed /message POST endpoint to properly forward JSON-RPC messages through SSE for standard MCP clients.

Full changelog

Bug fix

The /message POST endpoint was a stub that returned {status:"ok"} without forwarding JSON-RPC messages to the SSE transport. Standard MCP-over-SSE clients (e.g. mcp-remote, used by Claude Desktop) connected successfully but observed zero tools because their initialize and tools/list requests vanished — the responses were never streamed back through the SSE channel.

What changed

Active SSEServerTransport instances are now tracked by sessionId, and /message?sessionId=... POSTs are routed through transport.handlePostMessage() — the canonical SDK pattern.

This bug had been present since SSE support was added and silently broke any client using the standard flow. The custom POST /sse shortcut still works as before, so clients that hit that path were unaffected.

Affected versions

All prior 1.x releases.
