Overview

AI-generated overview

Local MCP server that gives an assistant access to ChEMBL drug molecule and bioactivity data, with no API key required.

What you can do
  • Look up drug molecules and their bioactivity data from the ChEMBL database.
  • Retrieve compound and assay information for research questions about drugs and their measured effects.
  • No tool list is published, so the exact queries available are not documented; the server is described only as covering molecules and bioactivity.
When to use it
Useful when you want an assistant to answer questions about drug compounds, targets or bioactivity measurements and prefer a local, key-free connection to ChEMBL over manual lookups.
Requirements
Runs as a local process on the user's machine, installed from the npm package chembl-mcp over stdio. Node.js is needed for the npm package. No API key, environment variables or headers are declared. Desktop-only; not available as a web executable.
Before you install
The server queries the public ChEMBL database, so the substance of your queries leaves your machine. No credentials are requested, and no write, send or delete actions are documented, but the tool set is unpublished, so review what it exposes before relying on it.

Installation

In SourceWeft

  1. Open Chembl Mcp in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Score

25% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.

  • Tools listed15 pts

    Answer tools/list without a credential, or ship a package that starts in a sandbox without one.
