Metering
- One call = one unit by default (some tools may be weighted).
- Usage is aggregated month-to-date, broken down by connector and by tool.
GET /api/usage (same Stytch identity as MCP) returns:
Fair use
A fair-use policy guards against runaway automation. It has three modes:| Mode | Behaviour |
|---|---|
off (default) | Usage is recorded; nothing is ever blocked. |
soft | Over-limit is flagged but not blocked. |
hard | Calls beyond the limit are blocked once the quota is exceeded. |
Fair use fails open: if the usage store is unavailable, calls are allowed
(
withinQuota: true) rather than blocked. Normal usage within your plan is
included, and you’re warned before approaching any limit.
