Best for
  • Financial analysts and researchers needing fast, structured access to SEC filings.
  • Developers wanting to run SQL queries on SEC data directly within MCP clients.
  • Regtech and data scientists interested in XBRL data.
  • 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 requiring totally offline access to historical filings (though a local mirror option exists).
  • Scenarios needing real-time streaming or very low latency (SEC has rate limits and publication lag).
  • Users who want to avoid setting up their own EDGAR_USER_AGENT (but can use the hosted instance).
  • 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
  • Access to SEC EDGAR public API (no API key, but valid User-Agent required).
  • When self-hosting locally, runs a local server process that needs a Node/Bun runtime.
  • Optional: when using the local SQLite mirror, stores data and caches on disk.
  • 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
  • SEC requires a valid User-Agent like 'YourAppName [email protected]'; otherwise IP blocks could occur.
  • The tool accesses public APIs and may be rate-limited if too many requests are made.
  • As a non-official server, validate reliability and maintenance status before using in production.
  • 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
