Best for
  • Content teams already on Directus who want to read and write content via LLMs
  • Analysts querying Directus data with natural language
  • Directus projects wanting controlled, guardrailed data access for non-developers
  • Drug discovery and computational chemistry researchers
  • Bioinformatics teams needing ChEMBL data through AI assistants
  • Developers comfortable with Node.js or Docker
Not for
  • Projects not using Directus
  • Developers needing full destructive/admin operations on dev instances (field and collection deletion is intentionally limited)
  • Clients that do not support MCP
  • Production settings requiring official ChEMBL support (this is unofficial)
  • Users without a Node.js or Docker environment
  • General database tasks unrelated to ChEMBL
Required permissions
  • Requires the Directus instance URL plus a static token or email/password credentials
  • Actions are limited by the permissions of the associated Directus user
  • Outbound network access to https://www.ebi.ac.uk/chembl/api/data
  • Read-only access to public API data; no authentication credentials required
Risks and side effects
  • Has write access to create, update, and delete items and fields, so misconfiguration can still modify data
  • Leaked credentials grant LLM access to Directus data
  • While field/collection deletion is limited, item deletion remains available
  • Unofficial project with license marked NOASSERTION (README claims MIT); verify licensing yourself
  • Data accuracy depends on the ChEMBL REST API and the server's parsing may contain defects
  • 30-second request timeouts may constrain large batch queries
  • README inconsistency on tool count (22 vs 27) raises documentation reliability concerns
