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. (2026-07-27)
