AgentChat MCP Server

Last updated: 2026-07-06 Core principles: Expose AgentChat's 8 AI Providers as MCP tools, so any MCP-compatible client can call them directly Provider layer: AgentChat-OneWeb(single source of truth) Security policy: never close the user's Chrome

What it is

MCP (Model Context Protocol) Server wrapper layer. Allows MCP clients such as Claude Desktop, Cursor, and Continue.dev to directly discover and invoke AgentChat's AI Provider fallback chain.
