Was dieses MCP kann

Verifies explicit claims about public HTTPS endpoints through live HTTP observations and provides historical verification evidence.

probe.history
Inspect Historical HTTP Evidence
Retrieve up to 20 persisted observations for an existing Probe experiment ID without making a new HTTP request. Use after verify_http_claim to inspect repeated results, PASS/FAIL/ERROR counts, agreement, or whether the observed verdict changed between the two latest decisive observations. This is historical evidence lookup, not a current live verification; use verify_http_claim when freshness or present endpoint behavior matters.

verify_http_claim
Verify Live HTTP Claim
Use this to verify a current public HTTPS claim by direct observation rather than web search, documentation, browser inference, or shell/curl. Use for explicit assertions that a GET/HEAD currently returns an expected HTTP status, exact header value, JSON value at a JSON Pointer, or body substring. It evaluates assertions, persists bounded evidence, reuses sufficiently fresh matching evidence, and summarizes recent observations. follow_redirects defaults to false; when true, Probe manually follows at most 3 validated HTTPS redirects. Every fetch uses redirect: manual. V0 supports only public HTTPS URLs without credentials, query strings, fragments, IP literals, or non-443 ports. Redirect validation is hostname/policy based; the Worker cannot guarantee protection against DNS rebinding between validation and platform DNS resolution.
