glue-mcp

glue-mcp

A model context protocol (MCP) server to AWS Glue Data Catalog

Usage

Once you've built a binary (see below), ensure you have your AWS credentials set.

Then simply start the server:

./glue-mcp
2025-04-29T21:25:37.623408Z  INFO glue_mcp: Metrics & logging initialised
2025-04-29T21:25:37.623453Z  INFO glue_mcp::util: Starting server on 127.0.0.1:8000

The server is ready for MCP calls on port 8000.

Development

Nix

Just run nix develop, then cargo build.

Demo

We'll demonstrate using Ollama.

1. Install & configure mcphost

go install github.com/mark3labs/mcphost@latest

Configure mcphost with this MCP server:

{
  "mcpServers": {
    "aws_glue": {
      "url": "http://localhost:8000/sse",
      "transport": "sse"
    }
  }
}

2. Configure Ollama

Get a model:

ollama pull llama3.1:latest

4. Run glue-mcp

cargo run

5. Run mcphost & query

~/go/bin/mcphost --config ./mcp.json --model ollama:llama3.1
