## Quality 79/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-03-26; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 71 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: check_stripe_code (readOnlyHint, destructiveHint, idempotentHint, openWorldHint)
- pass `tools.token_cost`: about 219 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: no tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 1, about 219 tokens to load them all
- tool set hash: 09a7e46b8d3c4f30397613c76452e576
- badge: [![protogrid quality](https://protogrid.dev/badge/app.vercel.stripecheckup/stripecheckup.svg)](https://protogrid.dev/servers/app.vercel.stripecheckup/stripecheckup)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (1)

- `check_stripe_code`: Paste Stripe integration source code (a webhook handler, a checkout-session-creation route, or both concatenated) and get back pattern-based findings for the most common integration bugs: missing webhook signature verification, missing customer.subscription.updated handling (the single most common bug -- dunning marks a subscription past_due/unpaid, not canceled, so a handler that only reacts to .deleted leaves non-paying customers with access forever), missing checkout metadata/client_reference_id, and premature customer creation. This is regex pattern matching over text, not a real parser -- treat a clean result as 'didn't find a problem', not a guarantee. Nothing pasted is stored.
