Eunomia MCP Server
Open Source Data Governance for LLM-based Applications — with MCP integration
Made with ❤ by the team at What About You.
Eunomia MCP Server is an extension of the Eunomia framework that connects Eunomia instruments with MCP servers. It provides a simple way to orchestrate data governance policies (like PII detection or user access control) and seamlessly integrate them with external server processes in the MCP ecosystem.
With Eunomia MCP Server, you can:
git clone https://github.com/whataboutyou-ai/eunomia-mcp-server.git
Eunomia MCP Server uses the same “instrument” concept as Eunomia. By defining your set of instruments in an Orchestra, you can apply data governance policies to text streams that flow through your MCP-based servers.
Below is a simplified example of how to define application settings and run the MCP server with uv.

Once your settings are defined, you can run the MCP Orchestra server by pointing uv to the directory containing your server code, for example:
uv --directory "path/to/server/" run orchestra_server
