Preview Execution monitoring

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.

About

Card Funding Risk

Stripe MCP Setup

Requires Stripe MCP connected via OAuth or restricted key. Docs: https://docs.stripe.com/mcp

  1. GetMcpTools with server: "user-Stripe" (or plugin-stripe-stripe) before any call
  2. Prefer stripe_api_search → stripe_api_details → stripe_api_read for list/retrieve
  3. Always paginate — limit: 100, follow has_more with starting_after
  4. Amounts are in cents unless noted
  5. Never expose secret keys in output

Workflow

  1. Paginate GetSubscriptions — statuses: active, past_due, trialing
  2. Expand data.default_payment_method
  3. Read payment_method.card.funding: credit | debit | prepaid | unknown
  4. Cross-tab: funding × status (active vs past_due)

MRR Normalization

Same as mrr-arr-snapshot — report prepaid/debit MRR separately.

Blocking Options

| Approach | Catches | Misses | |----------|---------|--------| | Radar: Block if :card_funding: = 'prepaid' | Prepaid, many disposable | Virtual debit | | Radar: 3DS on new cards | Fraud, some disposable | Low-balance debit | | Webhook reject on prepaid | Post-checkout cleanup | After first charge |

Requires Radar for Fraud Teams for custom rules.

Output Template

Card Funding Audit

| Status | Credit | Debit | Prepaid | Unknown |
|--------|--------|-------|---------|---------|

Past due with prepaid: [n] / [total past_due]
Active with prepaid: [n] / [total active]

Prepaid subs (detail):
| sub | last4 | country | MRR |

Recommendation: [block prepaid / 3DS / monitor debit past_due rate]
