Streamable-HTTP MCP server (io.modelcontextprotocol.sdk:mcp 2.0.0) mounted on the daemon's Jetty at /mcp, exposing three tools as thin adapters over MessageService/Rendezvous — the primary calls bridge_send/bridge_status, the worker calls bridge_reply. Tool logic in unit-testable static methods (parity tests); SDK owns the wire protocol. Resolves the Jackson 2/3 split by pinning jackson-annotations 3.0-rc5 (works for both our Jackson 2.19 and the SDK's Jackson 3). Live-verified: initialize handshake + tools/list return all three tools. Documents the residual Jackson-3 CVE (loopback, trusted clients). 52 tests green, IDE-clean.
