Show HN: MetaMCP – Open-Source MCP Aggregator, Middleware, Gateway in One Docker

Hi HN! I am James, author of MetaMCP and we recently rewritten MetaMCP 2.0 and invite you to test the new app. It is open source and MIT licensed.

How it works

- Group MCP servers into namespaces

- Expose them as unified meta-MCP endpoints (with SSE or SHTTP in MCP or openapi.json to use in Open Web UI etc.)

- Plug in middlewares: widely used one is to filtered out unused tools. More to come soon like loggings, human-in-the-loop, guardrails, you can also leave github issues to discuss

- Pre-built docker image to quickly setup

Things you might find interesting:

- We pre-warm idle sessions to reduce cold start latency

- You can debug via a built-in MCP inspector

- You can even run multiple MetaMCPs inside a MetaMCP (yes, we tried )
