This MCP Server acts as a bridge between Claude's Model Context Protocol (MCP) clients and the Drug Gene Interaction Database (DGIdb) API. It enables Claude Desktop to query DGIdb data—such as drug–gene interactions and related drug attributes—via the DGIdb GraphQL API at https://dgidb.org/api/graphql. The server code is defined in src/index.ts, which specifies how the server connects to DGIdb and what tools it exposes to MCP clients. Deployment can be performed on Cloudflare Workers, and, once deployed, clients connect via an SSE endpoint (e.g., /sse). Claude Desktop configuration is demonstrated by embedding the server URL within Claude's mcpServers configuration (e.g., using npx mcp-remote). Example queries mentioned in the README include asking for interactions of a drug (e.g., Imatinib), finding genes that interact with a drug, or showing drug attributes. The project is licensed under MIT with an Academic Citation Requirement, and the README provides practical guidance for connecting Claude Desktop to the MCP server and restarting the application after changes.
