Best for
  • Teams already on Snowflake who need to study or reproduce a legacy MCP integration for migration purposes
  • Developers researching this project's architecture before moving to the official Snowflake MCP Server
  • Drug discovery and computational chemistry researchers
  • Bioinformatics teams needing ChEMBL data through AI assistants
  • Developers comfortable with Node.js or Docker
Not for
  • Any new project or production deployment, since the project is officially deprecated with no further fixes or features
  • Users unfamiliar with Snowflake RBAC and SQL statement allowlisting who cannot audit the permission configuration themselves
  • 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 valid Snowflake credentials (username/password, PAT, key pair, OAuth, or SSO)
  • Server behavior is fully bound by the RBAC permissions of the connecting role, which needs access to the target databases/schemas/warehouses/Cortex services
  • Enabling SQL execution or object-management tools requires explicitly allowlisting SQL statement types (Create, Drop, Update, etc.) in the configuration file
  • 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
  • The project is officially marked deprecated and unmaintained, so unresolved security or functional issues may exist — not recommended for new deployments
  • Misconfigured sql_statement_permissions or an 'Unknown' statement type set to True can allow destructive SQL (DROP, DELETE, UPDATE) to execute beyond intended scope
  • Sensitive credentials (private keys, passwords) are passed via environment variables or CLI arguments, requiring careful protection of the deployment environment
  • Programmatic Access Tokens (PATs) do not evaluate secondary roles, forcing a single broadly-privileged role and coarser permission control
  • 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
