ChEMBL MCP
The ChEMBL MCP server connects AI agents to the EBI drug discovery database, enabling searches for molecules, targets, assays, and documents. It provides tools to retrieve full molecule records, target details, mechanism of action, bioactivity data, and drug indications. The server is accessible via a gateway with a free tier allowing 50 calls per day without authentication.
Package and access
