## Trust

- hygiene: 100
- liveness: 0
- freshness: 65
- provenance: 85
- drivers: +repository +dns-namespace +website -unreachable(12 failures) ~updated-90d-ago
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 73/100 (needs work)

### 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: 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: preflight (readOnlyHint, destructiveHint, idempotentHint, openWorldHint)
- pass `tools.token_cost`: about 195 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

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

- n/a `stability.changes`, `stability.rug_pull`: tool history not recorded yet

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

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

- tools: 1, about 195 tokens to load them all
- badge: [![protogrid quality](https://protogrid.dev/badge/io.ironshell/preflight402.svg)](https://protogrid.dev/servers/io.ironshell/preflight402)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (1)

- `preflight`: One free call before your agent pays.

Probes the URL (no wallet, payment, or auth) and returns a
trust-preview.v1 verdict: liveness and latency, TLS validity, the 402
payment handshake with protocol detection (x402 v1/v2, MPP-capable),
detected networks/asset/price with a USD estimate, ERC-8004 identity
binding with Sybil-filtered reputation for the payee (which can adjust
the recommendation), and a proceed / caution / avoid recommendation with
human-readable reasons. Paid-tier fields (uptime history, reseller
analysis) are present but null on the free tier.
