STRING-DB MCP — protein-protein interaction networks.

Part of Pipeworx — an MCP gateway connecting AI agents to 673+ live data sources.

Tools

Tool	Description
`resolve`	Map free-text identifiers (gene symbols, accessions) → STRING identifiers.
`interactions`	Interaction partners for a set of proteins.
`network`	Network image url + tabular interaction data.
`enrichment`	Functional enrichment (GO, KEGG, Pfam, Reactome, …) for a gene set.
`homology`	Homology mappings.

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

{
  "mcpServers": {
    "string-db": {
      "url": "https://gateway.pipeworx.io/string-db/mcp"
    }
  }
}

Or connect to the full Pipeworx gateway for access to all 673+ data sources:

{
  "mcpServers": {
    "pipeworx": {
      "url": "https://gateway.pipeworx.io/mcp"
    }
  }
}

Instead of calling tools directly, you can ask questions in plain English:

ask_pipeworx({ question: "your question about String Db data" })

The gateway picks the right tool and fills the arguments automatically.
