metamcp
MCP Aggregator, Orchestrator, Middleware, Gateway in one docker
Aggregating several MCP servers into one endpoint with middleware applied, from a single Docker deployment that plugs into any MCP client.
You need steady upstream maintenance; the author notes a maintenance delay, and the forward development branch carries AI-agent changes with a request to test before building from it.
About metamcp
Latest Update: This ai-dev branch will be the forward onging dev branch which contains ai agent changes. Please test before you build the image based on this branch. There has been many PRs thanks to the community but merging and reviewing them has been a growing effort too. I decided to include ai changes. At least so far the core functionality works. There is also a community maintained fork (ty a lot!): https://github.com/Umbrella-IT-Group/metamcp
Update: From the author: apologize for some recent maintainence delay, but will at least keep merging PRs, more background [here]
