1.5.42

Patch Changes

• #1646 9ecc7cb Thanks @RhysSullivan! - Stdio MCP servers can negotiate the modern protocol (versionNegotiation: "auto")

  Spawned stdio MCP integrations previously always opened with the legacy 2025 initialize handshake, so an SDK v2 server running with its legacy compatibility lane disabled could not connect. Stdio integrations now accept versionNegotiation: "auto" (on mcp.addServer and the stored config) to probe server/discover per spec 2026-07-28, falling back to initialize on legacy servers. The default stays legacy: the SDK's stdio probe costs an extra short-lived child process per connect and stalls on silent legacy servers, which is the wrong trade for spawn-per-call CLI servers. The connect handshake span now records the negotiated era (plugin.mcp.protocol_era) so integration authors can verify which handshake a connection used.

1.5.41

Patch Changes

• #1617 a9b33d2 Thanks @RhysSullivan! - Support MCP spec 2026-07-28 end to end. The MCP client negotiates the protocol era automatically (server/discover probe with legacy fallback), so integrations hosted on modern-only MCP servers connect without the server enabling legacy compatibility. Executor-hosted MCP endpoints serve both eras, and the executor mcp stdio bridge passes either era through to the daemon.

1.5.35

Patch Changes

• #1435 af95edb Thanks @RhysSullivan! - Reuse downstream MCP sessions across tool calls. Remote MCP invocations now lease connections from a per-plugin-instance pool (one idle session per resolved credential identity, exclusive per invoke, 5-minute idle TTL) instead of dialing a fresh connection per call, so servers that key state by Mcp-Session-Id (workspace selection and similar) see consecutive calls in the same session. A reused session rejected with HTTP 404 is redialed once transparently; stdio transports and endpoint probing remain per-call.

1.5.28

Patch Changes

• #1246 1c48182 Thanks @RhysSullivan! - Keep MCP tool catalogs in sync with the server's live tool set. Previously a connection's tools were listed once at create time and never updated unless the integration's config changed or a user clicked Refresh, so server-side tool changes silently broke invocations.

  • tools/list discovery now follows nextCursor pagination per the MCP spec, so servers with paginated catalogs list completely instead of first-page-only.
  • The client handles notifications/tools/list_changed received during a tool call and marks the connection's persisted catalog stale; the next tools read re-lists from the server.
  • An unknown-tool rejection from the server (protocol error or the reference SDK's error envelope) returns a typed mcp_tool_unknown failure telling the caller to re-list, and marks the catalog stale so it heals on the next read.
  • Remote catalogs now also refresh on read once older than a freshness TTL (ExecutorConfig.toolsSyncTtlMs, default 15 minutes, null to disable), covering servers that change tools without notifying.
  • A failed listing (server unreachable, auth not ready) no longer wipes the previously persisted catalog; it is kept and retried after the TTL.
