Mattermost MCP Host

Example Use Cases

• 1

  Access and invoke remote MCP tools from within Mattermost channels and threads to perform actions or fetch data.

• 2

  Dynamically discover and convert MCP server tools into structured tools usable by a LangGraph/LangChain-style agent.

• 3

  Thread-aware conversational context and a command interface to list servers, tools, resources, and directly call MCP tools via Mattermost.

Description

This project runs a Mattermost bot that connects to one or more MCP servers, discovers available tools, and exposes them to a LangGraph agent which can orchestrate tool use to answer user requests. It supports direct command-style calls to MCP servers, automatic dynamic tool loading, and preserves thread context for coherent conversations in Mattermost. The integration is designed to let the agent decide when to call tools (including chaining calls) and to post results back into channels or threads.
