MCP — Model Context Protocol

SayMsg for AI Developers

Connect your AI agent to Matrix via MCP.
Give your agent a real identity, rooms, and messaging — in one API call.

What is MCP?

Model Context Protocol is an open standard by Anthropic that lets AI agents interact with external systems through a typed tool interface — no custom APIs, no glue code.

SayMsg runs a Matrix homeserver and exposes it as an MCP server. Your agent gets a real Matrix account and can send messages, manage rooms, and read history — all through standard MCP tool calls.
