Feyod MCP Server

FastMCP-based Model Context Protocol (MCP) server for querying Feyenoord football match data using natural language. Compatible with Claude Desktop and other MCP clients.

The server is publicly available at https://mcp.feyod.nl/mcp and a Docker container is available on Docker Hub (jeroenvdmeer/feyod-mcp).

---

Overview

This MCP server provides a natural language interface to query Feyod: Feyenoord Open Data. The underlying database is maintained in the feyod GitHub repository. You will need to obtain the latest SQL file from that repository to set up the required database.

The server uses LangChain to:
1. Convert natural language questions into SQL queries (optionally leveraging few-shot examples for better accuracy).
2. Validate the generated SQL.
3. Attempt to fix invalid SQL using an LLM.
4. Execute the valid SQL against a SQLite database.
5. Return the raw query results.

LLM and embedding models are dynamically loaded based on configuration using a provider factory (llm_factory.py), allowing easy switching between providers like OpenAI, Google, etc.

Consumption

Using the Public Endpoint

The Feyod MCP server is publicly available at https://mcp.feyod.nl/mcp. You can connect to this endpoint from any MCP-compatible client, such as Claude Desktop.

Using the Docker Container

A Docker image of the Feyod MCP server is available on Docker Hub. You can pull and run it using the following commands:

1. Pull the Docker image:

    docker pull jeroenvdmeer/feyod-mcp

    

2. Run the Docker container:
You will need to provide the necessary environment variables for the LLM provider and API key. You can also mount the feyod.db file if you want to use a local database instead of the one included in the image.

    docker run -p 8000:8000 \
      -e LLM_PROVIDER="your_llm_provider" \
      -e LLM_API_KEY="your_api_key" \
      jeroenvdmeer/feyod-mcp
    

To mount a local database file:

    docker run -p 8000:8000 \

      -e LLM_PROVIDER="your_llm_provider" \

      -e LLM_API_KEY="your_api_key" \

      -v <absolute_path_to_feyod_db>:/app/feyod/feyod.db \

      jeroenvdmeer/feyod-mcp

Tools

This server exposes MCP tools for querying the Feyenoord database. Tools are discoverable via the MCP protocol (tools/list).

- query_feyod_database: Converts a natural language query about Feyenoord matches into a SQL query, executes it, and returns the SQL query and its result.

See the MCP Inspector or Claude Desktop's tool list for details.

Setup

1. Clone repositories:

    # Clone this repo for the MCP server

    git clone https://github.com/jeroenvdmeer/feyod-mcp.git

# Clone the Feyod database

    git clone https://github.com/jeroenvdmeer/feyod.git
# Change directory into the MCP server

    cd feyod-mcp

    

Refer to https://docs.astral.sh/uv/ for the installation instructions of uv.

    uv venv
    .venv\Scripts\activate  # Windows
    # or
    source .venv/bin/activate  # macOS/Linux
    

    # Using uv (recommended)
    uv add "mcp[cli]" langchain langchain-openai langchain-google-genai python-dotenv aiosqlite
    # Or using pip
    pip install -r requirements.txt
    

    # Change directory to the feyod directory with the SQL file
    cd ../feyod
# Build the SQLite database using the SQL statements

    sqlite3 feyod.db < feyod.sql
