Chembl

ChEMBL drug discovery DB — molecules, targets, activities (EBI)

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

Tools

Tool	Description
search	Search molecules / targets / assays / documents.
molecule	Full molecule record by ChEMBL ID (e.g. "CHEMBL25" = aspirin).
target	Target record by ChEMBL target ID.
mechanism	Mechanism of action records (filtered by molecule_chembl_id).
activities	Activity records — filter by molecule or target.
drug_indications	Drug indication records.

Quick Start

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

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

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

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