Drift ledger · contract changes observed
Drift ledger
Public proof of the problem the gate solves. mcpindex crawls the public MCP registry every day and records which tool contracts silently change. This is that record — the same corroborated drift the gate asks the network about when you pin a tool, so it can warn you on the first call. A contract-diff, not a safety verdict, and not prevention; the gate is what HOLDs the call.
Observed
85 tools changed their contract
across 876 contract changes observed (a tool can change more than once)
- Servers affected
- 17
- Safety-relevant contract changesChanges that touch a safety-relevant field - not confirmed vulnerabilities.
- 57
Honesty
These are contract changes mcpindex's crawler OBSERVED between two daily registry snapshots - a contract diff, not a safety verdict, and not an in-path prevention (that is the gate).
Absence from this list is not a clean bill of health: a private or un-crawled tool never appears here.
No server pays to be listed or de-listed.

Events
Tools and servers are shown as content fingerprints, not names: mcpindex reports that a contract changed without publicly naming a specific server. A dash means no server fingerprint was recorded.
