## Trust

- hygiene: 100
- liveness: 100
- freshness: 85
- provenance: 90
- drivers: +repository +namespace-matches-repo +website +reachable +uptime-100% ~updated-67d-ago
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 86/100 (good)

### protocol: 100 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- pass `protocol.list_ttl`: tool list is cacheable (ttlMs 3600000)

### 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: 86 (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`: 18 of 18 tools declare readOnlyHint or destructiveHint
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: resolve_name (destructiveHint, idempotentHint); aura_read (destructiveHint, idempotentHint); roast_target (destructiveHint, idempotentHint); …
- pass `tools.token_cost`: about 3,014 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: 50 (weight 15)

- warn `deps.known_vulns`: 1 advisory of lower severity or without a published fix: GHSA-5r4p-p66f-jhc7 in hono@4.13.9 (indirect, fixed in 4.13.11)
- fail `deps.mcp_sdk_version`: @modelcontextprotocol/sdk 1.30.1 has 3 known advisories (GHSA-22jm-h49p-29qw, GHSA-6prh-2h8m-c8cw, GHSA-6qxp-vccf-f47h); update @modelcontextprotocol/sdk to 1.32.0 or later
- pass `deps.resolvable`: anchor-x402-mcp@0.2.3 resolved: 116 packages

- tools: 18, about 3,014 tokens to load them all
- tool set hash: 3e7414b2148a3c8d0aa43fb8e079553c
- tools last changed: 2026-10-18T01:08:56.389Z
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.hypeprinter007-stack/anchor-x402.svg)](https://protogrid.dev/servers/io.github.hypeprinter007-stack/anchor-x402)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.
