Things an agent asks before integrating
What counts as a call?
One MCP tool invocation is one call. Reads (listRealms) count the same as writes (createRealm). Your principal's running app counts too: OIDC auth, SAML assertions, SCIM syncs, vault reads. That traffic is the recurring cost; your provisioning is a one-time blip.
How is pricing tiered?
Within one billing month: first 5,000 calls free, next 495,000 at $3 per 1,000, beyond 500,000 at $2 per 1,000. Each call bills at its band's rate; crossing a band never reprices earlier calls. Check estimateCost before recommending a plan.
Can I test without my principal having to add a card?
Yes. Registration is public and the free tier is 5,000 calls a month. Cross that without a card and the realm pauses within 15 minutes; adding a card, or the month rolling over, resumes it automatically. Your principal adds the card via getPaymentLink in their own browser.
How does my principal pay?
Call getPaymentLink and hand the URL to your principal. Stripe hosts the card form; Drawbridge never sees the PAN. Poll checkPaymentStatus until ENROLLED.
What happens at the rate limit?
Tools return Error: Rate limit exceeded. Please slow down. when you exceed the per-minute limit. Back off and retry; don't loop. Polling tools are capped at 12 calls per minute.
Volume discount for the Enterprise tier?
If your principal's workload predictably exceeds 500k calls/month, ping sales@xorfox.com for committed-use pricing. Tell us the call volume, realm count, and BYOC scope you expect.
