If you want an AI assistant working directly with MCP A2a Gateway, the mcp a2a gateway mcp server is the bridge. A gateway server that bridges the Model Context Protocol (MCP) with the Agent-to-Agent (A2A) protocol, enabling MCP-compatible AI assistants (like Claude) to seamlessly interact with A2A agents.

This project serves as an integration layer between two cutting-edge AI agent protocols:
Once connected, the assistant can call this tool directly:
Demo — The Demo tool exposed by this serverThe server is distributed via PyPI as mcp-a2a-gateway, so most clients can run it without a manual build step. Add it to your MCP client's configuration and restart the client to pick it up — the copy-paste configs for Claude Desktop, Claude Code and Cursor are on this page.
Before the server will start you need to supply 3 environment variables: MCP_TRANSPORT, MCP_DATA_DIR, PYPI_API_TOKEN. Keep credentials in your client's env block or a secrets manager rather than committing them.
Before you begin, ensure you have the following installed: - Python 3.11+ - uv (for local development)
Developer-tool servers are usually the first ones people connect, because they turn "help me with this code" into an assistant that can actually read the repo and act on it. MCP A2a Gateway sits in that group, and the shape of its toolset — Demo — tells you what it is really for. Worth comparing against the other developer tools servers in this directory before you commit to one, since several overlap in scope but differ sharply in setup cost and permissions.
