Overview

What is ChEMBL-MCP-Server?

ChEMBL-MCP-Server is a FastMCP wrapper server based on the chembl_webresource_client package that provides complete API access to the ChEMBL database. It is designed for researchers and developers who need programmatic access to drug discovery data and chemical tools.

How to use ChEMBL-MCP-Server?

Install dependencies with pip install -r requirements.txt, then start the server by running python chembl_searver.py. You can configure the host, port, transport method, and log level using command-line arguments such as --host, --port, --transport, and --log-level.

FAQ from ChEMBL-MCP-Server

What dependencies does ChEMBL-MCP-Server require?

It requires chembl_webresource_client, mcp, fastapi, uvicorn, and asyncio.

How do I start the server with the stdio transport?

Run python chembl_searver.py --transport stdio to use stdio transport instead of HTTP.

What API functions are available?

The server provides data entity APIs (activity, assay, target, molecule, drug) and chemical tool APIs (canonicalize SMILES, SMILES to InChI, SMILES to SVG, structural alerts).
