ARPA‑H API & Tools Registry

A machine-readable catalog of approved AI tools and data services available to ARPA‑H staff.

What this endpoint provides

This endpoint hosts an AI tool registry compatible with the Model Context Protocol (MCP) gallery standard. It allows GitHub Copilot and other MCP-capable platforms to discover and connect to curated AI tools and data sources approved for use within ARPA‑H.

Intended audience

ARPA‑H staff using MCP (e.g., GitHub Copilot) anywhere. Tool discovery is governed by your organization’s platform policies; in GitHub, Visual Studio Code, and other MCP clients. No manual configuration is needed on developer devices.

Curated & approved tools

All tools listed in this registry have been reviewed and approved by ARPA‑H. The catalog is maintained centrally and updated as new tools are onboarded. Use the #github channel in Slack with questions about tool availability or to request additions.

Usage & querying the registry

No setup is required for ARPA‑H GitHub members; GitHub Copilot and Visual Studio Code are already pointed at this registry as GitHub’s McpGalleryServiceUrl / MCP Registry URL. Approved tools just show up. If you want to see what’s currently in scope from the command line, the registry is a plain, unauthenticated JSON endpoint you can query with curl.
