Materialize provides built-in Model Context Protocol (MCP) endpoints that AI agents can use. The MCP interface is served directly by the database; no sidecar process or external server is required. These endpoints use JSON-RPC 2.0 over HTTP POST (default port 6876) and support the MCP initialize, tools/list, and tools/call methods.
