OFFX MCP Server provides direct access to the OFFX (Target Safety) drug and safety database, allowing searches for drugs, adverse events, alerts, and scores. It is designed for researchers and developers needing drug safety data.
Install via npm (npm install @uh-joan/offx-mcp-server), set the OFFX_API_TOKEN environment variable, and run as an MCP server with npx offx-mcp-server or as an HTTP server with USE_HTTP=true. Configure it in Claude Desktop by adding the server to claude_desktop_config.json.
The OFFX (Target Safety) database is a drug and safety database that the server queries for drugs, adverse events, alerts, and scores.
You need to set the environment variable `OFFX_API_TOKEN` with your OFFX API token.
Yes, set `USE_HTTP=true` and optionally specify a `PORT` (default 3000) to run as an HTTP server with REST endpoints.
Alerts support filters such as `adverse_event_id`, `alert_type`, `alert_phase`, `ref_source_type`, `alert_level_evidence`, `alert_onoff_target`, `alert_severity`, and more. Values must use OFFX-API compatible formats (e.g., comma-separated numbers for multiple values).
Include a `page` parameter (integer) in your requests. It defaults to 1 if not specified.
