It is a Model Context Protocol server that provides access to curated biological pathway and systems biology data from the Reactome database. Developed by Augmented Nature, it is designed for researchers and scientists exploring cellular processes, disease mechanisms, and drug targets.
Install via npm (npm install), build (npm run build), then run with node build/index.js. Configure your MCP client (e.g., Claude Desktop) by adding a reactome-server entry that points to the built script. Use any of the eight available tools by sending JSON‑RPC requests with the specified arguments.
No. It is an unofficial server developed independently by Augmented Nature. It uses the public Reactome Content Service API but is not affiliated with or endorsed by the Reactome project.
You need Node.js installed. The server is built from TypeScript source using `npm install` and `npm run build`, then runs via `node build/index.js`.
All data is fetched live from the Reactome Content Service REST API (`https://reactome.org/ContentService`, v79). No authentication is required for normal research use, and rate limits are generous.
It provides access to over 2,500 curated pathways, 25,000+ reactions, and 14,000+ proteins across 20+ species, including human, mouse, and rat. It covers signal transduction, metabolism, gene regulation, cell cycle, DNA repair, immune response, and disease mechanisms.
