Module server 

The in-process MCP server.

Holds a registry of Tool implementations and dispatches JSON-RPC requests to them. Transport is OUT of scope here - this type is a pure request/response router. The mcp::orchestration module wires dispatch calls to the mcp_message control-request arm of Client::handle_control.

Structs

McpServer

A fully-constructed MCP server. Clone is cheap (just bumps Arcs).

McpServerBuilder

Builder for McpServer.

Enums

Negotiated 🔒

What the client’s requested version resolved to. Kept distinct from the answered string because an unsupported version and a missing one are different events: protocolVersion is required, so the latter is a broken client rather than a negotiation outcome.

Functions

classify_protocol_version 🔒

negotiate_protocol_version 🔒

Echo the client’s requested protocol version when we speak it, else answer with our latest - the spec’s SHOULD for an unsupported request.
