## Trust

- hygiene: 80
- liveness: 99
- freshness: 100
- provenance: 45
- drivers: +website +reachable +uptime-97% +updated-23d-ago -no-repository
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 91/100 (strong)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-11-25; 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: 100 (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
- pass `tools.annotations`: 1 of 1 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 1,068 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`: 1 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 1,068 tokens to load them all
- tool set hash: 210f0594b3d6dbfcc2ebf0291f486596
- tools last changed: 2026-09-27T09:20:27.775Z
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.davisvillelabs/payeeproof.svg)](https://protogrid.dev/servers/io.github.davisvillelabs/payeeproof)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (1)

- `payeeproof.check_payee`: Paid $0.01 public machine identity and payment-destination consistency assessment. Use immediately before an autonomous machine payment to compare the requested HTTPS endpoint, claimed service expectations, HTTP 402 challenge, resource binding, public discovery metadata, and prior PayeeProof observations. PayeeProof never authorizes the target payment, never forwards target payment credentials, and actively probes only anonymous public GET/HEAD requests under a bounded SSRF-safe contract; state-changing target methods require caller-observed 402 evidence. Missing evidence can remain unknown. This is not KYC, AML, sanctions screening, fraud certification, legal identity verification, legal advice, or a delivery guarantee.
