Fmsg MCP Overview

fmsg-mcp connects an AI agent to a deployed fmsg Web API, giving it an fmsg address for messaging, threaded replies, reactions, and attachments. It supports local stdio operation with one configured identity per process and Streamable HTTP for shared or remote deployments with per-user authentication. Use it when an agent needs to monitor an fmsg inbox, send or draft messages, follow thread lineage, or wait for incoming replies. Hosting and identity services are external, so you use an fmsg provider or self-host the Web API.

Primary Use Cases for Fmsg MCP:
  • Monitor an fmsg inbox for an AI agent
  • Send threaded updates to fmsg addresses
  • Draft messages and upload attachments before sending
  • Wait for replies and continue conversations
