groundcheck-mcp
MCP connector that verifies a claim's grounding against reality (quotes, citations, code, repos, math) with no LLM in the verification path. Works in Claude and Gemini.
I built this MCP connector to check whether the grounding behind a claim is real. Is the quote actually on the page? Does the arXiv id resolve? Does the code print what someone says it prints, and is the number right? There's no language model anywhere in the verification path. It works in any MCP host, so Claude, Gemini or something else. The checkers under verify/ re-derive every verdict it returns. They run against the same fixtures and don't share the server's code. If a re-derivation drifts, the build stops.
