Trigger.dev Docs added to the registry — baseline recorded with 3 tools
Public MCP servers publish a tool contract and change it without notice: no versions,
no deprecation policy, no changelog feed. This registry reads
tools/list from 79 of them on a schedule, canonicalises every
schema and records the difference. Deterministic, no model in the loop.
Read the row count with its caveat: those 79 endpoints resolve to
21 independent contract families, because 51 of them are served by a single hosted platform (mintlify-docs). One template change there moves dozens of rows on the same day, and that is one event, not dozens.
How that was measured →
Which contract each of them serves →
Newest first. A silent drift is a schema change shipped while the human-readable description stayed byte-identical — the case no changelog and no RSS feed can report.
Fingerprint is a SHA-256 over the canonicalised tool set. Identical fingerprint, identical contract. Rows sharing a platform are not independent observations. Rows marked unstable are under reachability quarantine: their up/down events are withheld, their contract is still diffed.

No language model decides anything here. Schemas are canonicalised — keys sorted, whitespace dropped — then compared structurally. A change is breaking when a parameter or enum value disappears, a type changes, or a field becomes required.
A heartbeat canary runs every pulse against a source guaranteed to move, because “nothing changed” and “the collector is broken” otherwise look identical.
Healthy. Reference source last moved 2026-09-09; the collector and the diff path are both confirmed live.
79 endpoints checked on the last pulse: 79 counted healthy, 0 in reachability quarantine, 0 unreachable.
No host is flapping; the quarantine is empty. It fills at four up/down transitions in seven days and empties on its own.
79 endpoints, 21 independent contract families. Each declared platform counts once; each endpoint with no identified platform counts as its own, since an unlabelled server is unproven, not proven independent.
mintlify-docs51 endpointsopenapi-explorer5 endpointsmintlify-search-only4 endpointsgitmcp2 endpoints74 of 79 contracts came back from a direct POST;
5 needed a full initialize handshake. 76 arrived as an SSE stream rather than a plain body. 4 went through a method-preserving redirect, and 4 were read from a URL other than the declared one.
A redirect that would change the method is refused, not followed — a page fetched instead of an endpoint is not an observation, and every record says which of the two it is.
Pulses are idempotent against the last committed snapshot, so a delayed or skipped run costs latency and nothing else. First pulse 2026-09-09.
