mcp

Model Context Protocol transports and types.

mcp provides Riot's typed surface for speaking MCP. It is the package you use when you want to model MCP requests, responses, capabilities, and transport messages in OCaml instead of treating the protocol as an untyped JSON blob.

Install

riot add mcp

What it is for

  • building MCP servers or clients in Riot;
  • sharing protocol types between transport code and application logic;
  • writing tests against real protocol shapes instead of ad-hoc JSON.

What it is not

mcp is not an agent framework by itself. It gives you the protocol language. You still need to decide how you host tools, route requests, and integrate with your application.

Related packages

  • jsonrpc is the closest neighbor conceptually.
  • lsp is another example of Riot packaging a protocol as typed OCaml data rather than raw JSON.
