Agent MCP Gateway runs on your own machine — the client starts it, so there is no endpoint to ping. 165 installs a week from pypi. Last commit 2 Dec 2025.
On-demand tool discovery for all your MCPs and per-subagent MCP controls to preserve context window.
Today is the operative word: we check Agent MCP Gateway every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

This one needs environment variables set before it will start:
GATEWAY_MCP_CONFIG (Path to MCP servers configuration file (default: .mcp.json)), GATEWAY_RULES (Path to gateway access control rules file (default: .mcp-gateway-rules.json)), GATEWAY_DEFAULT_AGENT (Default agent ID when not provided in tool calls), GATEWAY_DEBUG (Enable debug mode and expose diagnostic tools (default: false)).
The author declared them in the registry entry; get the values from the project itself.
