Best for
  • Teams on Tableau Cloud that want a quick managed OAuth-based setup
  • Tableau Server customers who need self-hosted infrastructure
  • Developers building AI applications that integrate with Tableau
  • Drug discovery and computational chemistry researchers
  • Bioinformatics teams needing ChEMBL data through AI assistants
  • Developers comfortable with Node.js or Docker
Not for
  • Users without a Tableau Cloud or Tableau Server environment or license
  • Scenarios that only need static report exports without agent interaction
  • Local environments that cannot meet the Node.js 22.7.5 or later requirement (self-hosted option)
  • 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
  • Access to the Tableau site and data (configured for self-hosting via SERVER, SITE_NAME, PAT_NAME, PAT_VALUE)
  • OAuth 2.1 sign-in with the user's own Tableau Cloud identity under the hosted service, inheriting existing per-user permissions
  • Read access to Tableau content to support data queries, content exploration, and view inspection
  • 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
  • Leaked PAT credentials (PAT_NAME, PAT_VALUE) could allow unauthorized Tableau access, so they must be kept secure
  • The data an agent can read is bounded by the signed-in identity's permissions, but sensitive data the user can access may still be exposed
  • The self-hosted option requires maintaining your own runtime and security updates
  • Using the hosted service means Tableau content is processed through https://mcp.tableau.com
  • 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
