# Croissant MCP Server POC A Model Context Protocol (MCP) server POC for indexing and providing access to Croissant datasets. ## Interact w MCP server at your MCP client (e.g. Cursor) Copy paste following (dont worry about "your-api-key", just copy paste as you see below) into the mcp.jsonof your MCP client: ```json { "mcpServers": { "croissant-mcp": { "url": "http://54.188.239.243:8000/sse", "transport": "sse", "env": { "API_KEY": "your-api-key" } } } } ``` ## Available Endpoints - `/health` - Health check endpoint - `/mcp` - MCP endpoints - `/events` - SSE events for real-time updates - `/docs` - API documentation ## Available Tools ### Dataset Discovery - `list_datasets()` - List all available datasets - `search_datasets(query: str)` - Search datasets by name, description, or tags - `list_sources()` - List all data sources - `get_source_datasets(source: str)` - Get datasets from a specific source ### Data Access - `get_dataset_metadata(dataset_id: str)` - Get detailed metadata ### Adding New Tools 1. Create a new tool function in `src/tools/` 2. Decorate with `@tool()` 3. Add type hints and docstrings 4. Register in `src/server.py`
