Expression Atlas

pipeworx-io/mcp-expression-atlas
HTTPregistry active
Summary

Connects Claude to the EBI Expression Atlas, a genomics database for gene and protein expression data across biological conditions and organisms. Part of the Pipeworx gateway ecosystem that bundles 815+ data sources under one MCP endpoint. The implementation is streamable over HTTP and supports plain English queries through ask_pipeworx rather than direct tool calls. Reach for this when you need to query gene expression patterns, differential expression data, or baseline expression levels from EBI's curated datasets. The tool list isn't documented in the README, but the gateway handles argument mapping automatically. You can connect to this individual server or use the full Pipeworx gateway for broader scientific data access.

mcp-expression-atlas

EBI Expression Atlas MCP.

Part of Pipeworx — an MCP gateway connecting AI agents to 815+ live data sources.

Tools

ToolDescription

Quick Start

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

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

Or connect to the full Pipeworx gateway for access to all 815+ 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 Expression Atlas data" })

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