gc-eval-mcp 1.2.0

MCP server for BizChat Gov Cloud quality evaluation data

GC-Eval MCP Server

A manifest-driven MCP server that exposes BizChat Gov Cloud quality evaluation data to any MCP-compatible client (e.g., Copilot CLI).

No repo access required. Install once, always up-to-date — data is fetched from a hosted endpoint at runtime.

Quick Start (for consumers)

pip install gc-eval-mcp

Add to .copilot/mcp.json in any project:

{
  "mcpServers": {
    "GC-Eval": {
      "command": "gc-eval-mcp"
    }
  }
}

Done. Restart Copilot CLI and the tools are available.

Adding New Data (for maintainers)

To expose new data through the MCP, update the manifest — no server code changes needed:

{
  "id": "my-new-data",
  "type": "sqlite",
  "tool_prefix": "my_data",
  "path": "data/my_new_data.db",
  "description": "My new dataset"
}

Supported types: html-collection, markdown, json, sqlite.

Upload the data file to the hosted endpoint, add the entry to manifest.json, and all MCP users instantly have access.

Development

cd mcp-server
pip install -e .
gc-eval-mcp

Or run directly:

python -m gc_eval_mcp
