Bumps rmcp from 1.7.0 to 3.0.0.

Release notes

Sourced from rmcp's releases.

rmcp-macros-v3.0.0

  • release stable 3.0.0

rmcp-v3.0.0

RMCP 3.0 adds support for MCP 2026-07-28. Review the protocol key changes and the RMCP 3.0 migration guide before upgrading from 2.x.

Breaking changes

  • Sessionless Streamable HTTP: MCP 2026-07-28 removes protocol-level sessions: no Mcp-Session-Id, standalone GET stream, DELETE-based session termination, or Last-Event-ID resumption. RMCP creates a fresh handler per request, so persistent state must live outside the handler. stateful_mode is renamed to legacy_session_mode and now only controls older protocol versions; custom SSE clients must also accept an optional session ID.
  • Stateless lifecycle and discovery: the 2026-07-28 protocol removes initialize/notifications/initialized; each request carries the protocol version and client capabilities in _meta, and servers expose server/discover. RMCP clients opt into this lifecycle with serve_with_lifecycle and ClientLifecycleMode::Discover or Auto; the existing serve() path remains available for legacy initialization.
  • Subscriptions and removed methods: subscriptions/listen replaces the standalone GET stream and resources/subscribe/resources/unsubscribe. ping, logging/setLevel, and notifications/roots/list_changed are unavailable under 2026-07-28; RMCP retains their APIs for legacy protocol sessions.
  • Multi Round-Trip Requests and result types: ServerHandler::call_tool, get_prompt, and read_resource now return MRTR-aware response enums. Manual handler implementations and exhaustive ServerResult matches must handle InputRequiredResult, and result models carry an optional result_type for legacy wire compatibility.
  • Tasks: the experimental core tasks API is replaced by the io.modelcontextprotocol/tasks extension, including new task handlers, methods, and TaskManager APIs.
  • Rust model types: metadata is split into MetaObject, RequestMetaObject, and NotificationMetaObject; Annotations::last_modified is now Option<String>; and tool structured content accepts any serde_json::Value.
  • OAuth: authorization startup is consolidated around AuthorizationRequest; metadata discovery is renamed to resolve_metadata and returns provenance; and custom OAuth HTTP errors are now boxed source errors.
  • Compatibility: APIs deprecated before 3.0 have been removed, and the minimum supported Rust version is now 1.88.
