Build a Munder Difflin Agent Orchestration MCP Server for Multi-Clone Coordination in 2026

The Orchestration Gap

Munder Difflin runs autonomous clones on your machine, but coordinating them requires the CLI. This FastMCP server wraps Munder Difflin's core operations into 6 MCP tools that any agent can call — enabling Claude, ChatGPT, or Cursor to manage your clone office programmatically.

Production Reality Check

Security: All inter-clone messages use E2E encryption. The MCP server runs locally on 127.0.0.1 with no external network access. Clone API keys stay on the local machine.

Last tested: August 2026 with Node v22, Munder Difflin v1.0, FastMCP v1.2.0, and MCP 2026-07-28 specification.
