Agent MCP Gateway

A Model Context Protocol (MCP) gateway that aggregates multiple MCP servers and provides policy-based access control for agents and subagents. Solves Claude Code's MCP context window waste by enabling on-demand tool discovery instead of loading all tool definitions upfront. It runs locally over stdio via the published package.

People connecting this server to Claude, Cursor, VS Code, or another MCP client. The project is written in Python.

01 · Install Agent MCP Gateway

before you install - you'll need

Set GATEWAY_MCP_CONFIG, GATEWAY_RULES, BRAVE_API_KEY, DATABASE_URL, GATEWAY_DEBUG before connecting. GATEWAY_DEFAULT_AGENT is optional or environment-specific per the README.

Claude Code

claude mcp add roddutra-agent-mcp-gateway -- uvx agent-mcp-gateway

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "roddutra-agent-mcp-gateway": {
      "command": "uvx",
      "args": [
        "agent-mcp-gateway"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

license MIT - declared in the repository

pypi package agent-mcp-gateway - check the name against the project README before installing (PyPI has no namespace ownership)

registry namespace io.github.roddutra is GitHub-verified and matches the repo owner

06 · Agent MCP Gateway FAQ

What is Agent MCP Gateway?

Is Agent MCP Gateway still maintained?

Yes - as of 2026-08-25, its last commit was 2025-12-02. We re-verify nightly.

How do I install Agent MCP Gateway?

Run `uvx agent-mcp-gateway`. The README documents 6 environment variables (GATEWAY_MCP_CONFIG, GATEWAY_RULES, GATEWAY_DEFAULT_AGENT…) to set first. Set GATEWAY_MCP_CONFIG, GATEWAY_RULES, BRAVE_API_KEY, DATABASE_URL, GATEWAY_DEBUG before connecting. GATEWAY_DEFAULT_AGENT is optional or environment-specific per the README. You can also paste the ready-made client config above.

Does Agent MCP Gateway run locally?

Yes - it's a stdio server: it runs on your machine (via uvx) with your user's permissions. Your data stays local unless the server itself calls external APIs.
