What is ChEMBL-MCP-Server?

ChEMBL-MCP-Server is an API service based on the FastMCP framework. It encapsulates the chemical and biological activity data of the ChEMBL database, providing a convenient query interface for researchers. Through this service, users can easily obtain key data such as drug molecules, biological targets, and activity tests.

How to use ChEMBL-MCP-Server?

You can access the ChEMBL database through simple API calls without complex configuration. The service supports two interaction methods: HTTP and standard input/output, which are suitable for integration requirements in different scenarios.

Applicable scenarios

It is suitable for scenarios such as drug discovery research, chemoinformatics analysis, and biological activity data mining. Researchers can quickly obtain the required chemical data through the API to accelerate the research process.
