Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

Input Validation
Validate at the edge, before the data touches logic or storage.
- Schema — type, required fields, allowed values. Reject unknown fields rather than ignoring them.
- Bounds — string length, number ranges, array size. An unbounded input is a DoS and a memory bomb.
- Format — emails, UUIDs, dates parsed and re-validated, not trusted as strings.
- Files — size limit, type allowlist (check content, not just extension), no path traversal in names.
- Reject with a clear 4xx and a message that says what's wrong — without leaking internals.
Never trust "it comes from our own frontend". The request can come from anywhere.
