Chembl Database
Query the ChEMBL database directly from Claude Code for drug discovery and bioactivity data. This wraps the ChEMBL API with proper rate limiting and retry logic, saving you from writing your own request handling. It requires uv and will prompt you to accept ChEMBL's terms on first use. Built by Google DeepMind as part of their science skills collection, so it's designed for researchers who need to pull compound data, bioassay results, or target information without leaving their editor. The utility script approach means you're not debugging API calls yourself, which is the right move for something this specialized.

ChEMBL Database Query
Prerequisites
uv: Read theuvskill and follow its Setup instructions to ensureuvis installed and on PATH.- User Notification: If .licenses/chembl_database_LICENSE.txt does not already exist in the workspace root directory then (1) prominently notify the user to check the terms at https://chembl.gitbook.io/chembl-interface-documentation/about, then (2) create the file recording the notification text and timestamp.
Core Rules
- [!IMPORTANT] Use the Utility Scripts: You MUST ALWAYS use the provided
utility script
scripts/chembl_api.pyfor all ChEMBL API interactions, including checking status. NEVER usecurlor custom Python requests to query the ChEMBL API directly. This ensures rate limit is enfoced and also retries on network errors.
