Best for
  • Teams already using the kintone platform who want an AI assistant to operate on apps and records
  • Administrators who need to bulk-maintain kintone fields, forms, or general settings
  • Developers who want to drive kintone REST API operations via natural language
  • Teams already using ClickHouse who want AI assistants to access data directly.
  • Scenarios requiring fast, read-only data queries and schema exploration.
  • Drug discovery and computational chemistry researchers
  • Bioinformatics teams needing ChEMBL data through AI assistants
  • Developers comfortable with Node.js or Docker
Not for
  • Users who do not use the kintone platform
  • Scenarios requiring access to apps inside kintone guest spaces (unsupported)
  • Bulk record imports that need to set attachment field contents directly (unsupported)
  • Scenarios requiring write access to the database without explicit opt-in.
  • Production environments with stringent security requirements that avoid default permission settings.
  • 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
  • A kintone login username and password, or API token(s) (up to 9, comma-separated)
  • Optional Basic auth username and password
  • Optional client certificate (PFX file and password) for secure-access domains
  • Actual app access depends on the View/Add/Edit/Delete kintone permissions granted to the account or token used
  • Requires read-only access to ClickHouse database (default).
  • Optional: write access via CLICKHOUSE_ALLOW_WRITE_ACCESS.
  • Optional: destructive operations via CLICKHOUSE_ALLOW_DROP.
  • 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 server can directly call the kintone REST API to add, update, and delete records, fields, and app settings, so mistakes can cause data loss or broken app configurations
  • Credentials (password, API token, client certificate password) are passed via command-line arguments or environment variables, so config files and env vars must be protected from exposure
  • Guest space apps are not supported, which can cause access issues if business processes rely on them
  • The README states this server is outside kintone's official API support channel; issues must be reported via GitHub Issues
  • If write access is enabled, AI might make unintended modifications.
  • If DROP access is enabled, data deletion could occur accidentally.
  • Credentials may be exposed via environment variables.
  • 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
