Crate rig_mcp 

rig-mcp

Model Context Protocol bridge for rig-compose tool registries, backed by the official rmcp SDK.

Skills cannot tell an McpTool apart from a rig_compose::LocalTool — both implement the same Tool trait. The same registry can be exposed as an MCP server via serve_stdio and consumed by another process via StdioTransport::spawn, with all spec-level concerns (JSON-RPC framing, capability handshakes, protocol-version negotiation) delegated to rmcp.
