STRING MCP Server

# STRING MCP Server Model Context Protocol (MCP) server providing access to the STRING protein-protein interaction database. ## Features 9 tools for protein interaction analysis: - Mapping protein identifiers to STRING IDs - Retrieving protein interaction networks - Finding interaction partners - Functional enrichment analysis (GO, KEGG, pathways) - PPI enrichment testing - Cross-species homology mapping - Protein name resolution Full endpoint documentation available in [ENDPOINTS.md](ENDPOINTS.md). ## Installation ### From GitHub ```bash npm install git+https://github.com/munch-group/string-mcp.git cd node_modules/string-mcp npm run build ``` ### From source ```bash git clone https://github.com/munch-group/string-mcp.git cd string-mcp npm install npm run build ``` ## Usage with Claude Desktop ```bash # Using built version claude mcp add string node /path/to/string-mcp/build/index.js # Or from npm global install claude mcp add string npx -y string-mcp ``` ## Configuration Add to your Claude Desktop config: ```json { "mcpServers": { "string": { "command": "node", "args": ["/path/to/string-mcp/build/index.js"] } } } ``` ## Common Species Taxon IDs - Human: 9606 - Mouse: 10090 - Rat: 10116 - Fruit fly: 7227 - C. elegans: 6239 - Yeast: 4932 ## Building ```bash npm run build ``` ## Dependencies - [@mcp/rest-utils](https://github.com/munch-group/mcp-rest-utils) - Shared REST utilities - @modelcontextprotocol/sdk - MCP SDK - zod - Schema validation ## License ISC
