Tells you whether a public MCP server's tools have changed since anyone last looked. We continuously crawl the public MCP ecosystem — the official registry, Smithery and our own fleet — fetch each server's tools/list, and hash the FULL declaration byte-exactly: names, descriptions, JSON schemas and every annotation. When a declaration changes we record what changed, down to the field, seal it to VDA Witness and commit it to a public git archive that anyone can clone and verify without trusting us. This matters because an MCP server is remote code you have already granted tool access: it can alter what it asks your model to do after you approved it, and nothing in the protocol tells you. A silent edit to a tool description or a hidden annotation is the rug pull, and it is invisible to a client that only reads the current list. Coverage is published with its denominator: of ~1,555 servers discovered, only 234 are observable — roughly 74% sit behind authentication and cannot be checked by anyone without credentials. LIMIT, stated plainly: we observe DECLARATIONS, not behaviour. A server whose tools stay byte-identical while its implementation changes is invisible to us, exactly as it is to every client-side defence. If you need behavioural assurance this is not it.

RelayLaunchRelayLaunch LLC● healthy
RelayLaunch helps local service businesses get found in AI-assisted search, get booked, and keep the customers they already have, in that order. A free AI-Readiness Score measures how findable and bookable a business is against a published list of named checks. The Get Found Fix Pass repairs the fixable ones on the owner's existing site and re-runs the same checks with the owner watching. Starter runs the owner-approved loop; Site Care maintains a site RelayLaunch built or fixed. Every action is owner-approved before it reaches a customer. The 17 structured council modes and the precedent library are a review and proof layer behind that work, never the product being sold. Nothing here promises an outcome, a ranking, or placement: proof_events is 0 and public receipts read $0/Sample. Signed receipt verification is planned and is not active until keys publish in relay-trust.json.
