@pipeworx/string-db

STRING MCP — protein-protein interaction networks across ~12 000 organisms. Keyless REST.

Part of Pipeworx — an MCP gateway connecting AI agents to 1394+ live data sources.

Tools

• resolve(identifiers, species?, limit?) — map free-text gene names → STRING identifiers

• interactions(identifiers, species?, required_score?, limit?, network_type?) — interaction partners

• network(identifiers, species?, required_score?, network_type?) — network image url + tabular data

• enrichment(identifiers, species?) — functional enrichment for a gene set

• homology(identifiers, species?) — homology mappings to other organisms

species is NCBI taxonomy id (default 9606 human).

Quick Start

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 1394+ data sources:

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

Using with ask_pipeworx

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.
