Verdicts

Payman Genie MCP

OAuth 2.1 with PKCE, two scopes, one-hour access tokens and refresh tokens rotated on every use and revoked on logout. No published pricing, status page, rate limits or changelog.

Stripe API + MCP

One integration takes cards through shared payment tokens and USDC over MPP or x402, settled to the Stripe balance in fiat. Card payments from agents have a 0.50 USD minimum, so per-call micropayments must use stablecoins.

Before you call either

Payman Genie MCP

  1. Pass the person's request to ask_genie in their own words; don't pick accounts or fill payment fields
  2. On needs_approval, stop and tell the person; approval happens in their Genie account
  3. Retry only after NOTHING_RAN or BUSY, never after OUTCOME_UNKNOWN
  4. Treat done as acted, not settled; check the activity history before confirming a payment
  5. Sign-ins from bridge 0.3.x lack genie:self; log out and sign in again to use the self-service tools

Stripe API + MCP

  1. Switch to an Agent-tagged restricted key or OAuth before 31 October 2026; other keys get a 401
  2. Call stripe_api_search and stripe_api_details before stripe_api_write to get the method and parameters right
  3. When a write needs approval, give the person the URL and retry only after they approve; approvals expire after 24 hours
  4. Send an Idempotency-Key on every create so a retry can't charge twice
  5. On 429, read Stripe-Rate-Limited-Reason and back off with jitter; a 429 without it is a lock timeout
