mcp-gtex

GTEx — Genotype-Tissue Expression human gene-expression atlas

Part of Pipeworx — an MCP gateway connecting AI agents to 250+ live data sources.

Tools

Tool	Description
`gene`	Gene metadata by Gencode id or symbol.
`median_expression`	Median expression across tissues for a gene (TPM).

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

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

Or connect to the full Pipeworx gateway for access to all 250+ 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 Gtex data" })

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