The MCP server exposes the same Lofty Developer API documented on this site to any Model Context Protocol client — Claude, or any other MCP-compatible agent — so it can find a lead, log a call, book an appointment, or move a deal forward with no integration code. There is no generated SDK and nothing to install; you point your client at one URL.
The server speaks Streamable HTTP (JSON-RPC 2.0) and is stateless by design — no session affinity between requests, so it’s safe to call from behind a load balancer or a serverless client.
