OpenNIH is a free, anonymous public service — the website at opennih.org and the public MCP endpoint at https://mcp.opennih.org/mcp. There are no accounts, so there is no support login: everything below is open to anyone.

How to reach us

The correction and report form is the working contact channel. It needs no account, it reaches the maintainers, and it is the same intake used for data corrections. Choose the surface your issue is about — pick “other” for a bug report, an MCP integration problem, a question about these policies, or anything that is not a specific wrong number. Leave an email in the optional contact field if you want a reply; leave it blank to stay anonymous.

Data coverage

Which fiscal years are loaded, which release each figure came from, and when the corpus was last retrieved. Check here first when a number looks stale or a year looks missing.

Methodology

The exact ranking formula, the RPG-research-only scope, entity resolution, and the documented limitations. Most "why is this number different from RePORTER?" questions are answered here.

Trust & governance

Independence and conflict-of-interest policy, how corrections are tracked and resolved, and what governance is in place versus still pending.

Using the MCP endpoint

The public MCP server is at https://mcp.opennih.org/mcp over streamable HTTP. It is anonymous and needs no API key. Before reporting a problem, two checks resolve most integration issues:
