v0.10.1

Patch Changes

• #​4237 23ce761 Thanks @​gesh! - Read the MCP client name/version and protocol version from each request's _meta (io.modelcontextprotocol/clientInfo and io.modelcontextprotocol/protocolVersion), so $mcp_client_name, $mcp_client_version, and $mcp_protocol_version keep populating under the MCP 2026-07-28 stateless revision, which removes the initialize handshake. Existing clients are unaffected — when _meta is absent, the values from the session token / initialize still apply.

Minor Changes

• #​4210 e732595 Thanks @​gesh! - feat(mcp): capture the negotiated MCP protocol version as $mcp_protocol_version

  The SDK now stamps $mcp_protocol_version — the MCP spec version negotiated at initialize (read off the server's initialize response) — on the $mcp_initialize event and on every subsequent event for the session (tool calls, listings, and the $exception sibling). It's persisted in per-server session info and, on stateless / multi-pod deployments, recovered on other pods from the session token, which now carries the client's requested version in a new pv field. Use it to track MCP spec-revision adoption and to break event metrics (error rate, latency) down by spec version.

  SessionTokenPayload gains an optional protocolVersion, and PostHogMCP.captureInitialize accepts an optional protocolVersion. (2026-07-21) (2026-07-22)
