Validate AI claims against live data.
An MCP server that lets AI agents fact-check their own research in real time — probing endpoints, counting competitors, and testing hypotheses against live registries instead of guessing.
Origin
This tool was born from an AI agent catching itself giving bad advice. During a research conversation about MCP business opportunities, the agent recommended building products based on claims like "competition is low" and "this API is freely available" — then built a prototype to test those claims and discovered several were wrong. Competitors it said didn't exist already had packages on npm. An API it recommended building on top of couldn't even be reached.
Ground Truth is the tool that conversation needed.
Tools
check_endpoint
Probe a URL or API endpoint. Returns HTTP status, content type, response time, auth requirements, rate limit headers, and a structural summary of the response.
"Is this API actually accessible, or am I recommending something that doesn't work?"
estimate_market
Count packages/servers in a space on npm or PyPI. Returns total count, top results with version history and update dates, and activity signals.
"I'm about to say 'competition is low' — is that actually true?"
test_hypothesis
Test a factual claim against multiple live checks. Returns pass/fail per test and an overall verdict: SUPPORTED, REFUTED, or PARTIALLY SUPPORTED.
"Before I present this conclusion, let me verify it."
