Show HN: Mcp-plugins CLI/py equips your MCP with powerful prebuilt plugins

mcp-plugins is an open source project that ships with a collection of prebuilt MCP middleware plugins to let you add logging, rate limiting, error handling, cherry pick tools you only need, human approval etc. to your MCP, within one command setup. You can use mcp-plugins cli with a config.json input to proxy on top of your MCP servers or you can use it as prebuilt middleware lib in python with FastMCP.

As MCP gains more and more adoption, proxy, gateways & middleware become important pattern but there limited resources of prebuilt middleware as examples. This project is pretty early stage and experimental, but try to demonstrate a few use cases. And the provided python lib and cli will give you very easy and quick setup to try it out. You can also fork and customize the middleware there.

You can check the repo README for list of prebuilt plugins and how to use it.
