Seed Oil Tracker MCP Server

A free, hosted MCP server that gives AI assistants live access to the largest restaurant seed oil database: 500+ US chains, 40,000+ menu items, each with an estimated PUFA (polyunsaturated fat) value built from published nutrition data and disclosed cooking oils.

Ask your assistant things like:

• Does Chick-fil-A use seed oils?

• What oil does Chipotle cook with?

• What is the cleanest thing to order at Five Guys?

• Which chains have the lowest seed oil overall?

Run locally (stdio)

Prefer a local process, or your client only speaks stdio? This repo ships a zero-dependency stdio server (server.py, Python 3.8+, standard library only). It answers the MCP handshake locally and forwards tool calls to the hosted endpoint.

python server.py

Claude Desktop config example:

{
  "mcpServers": {
    "seed-oil-tracker": {
      "command": "python",
      "args": ["/path/to/server.py"]
    }
  }
}

Or with Docker:

docker build -t seed-oil-tracker-mcp .
docker run -i seed-oil-tracker-mcp
