## Trust

- hygiene: 100
- liveness: 98
- freshness: 65
- provenance: 80
- drivers: +repository +namespace-matches-repo +reachable +uptime-94% ~updated-131d-ago
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 70/100 (needs work)

### protocol: n/a (weight 25)

- n/a `protocol.modern`, `protocol.stateless`, `protocol.transport`, `protocol.list_ttl`: no remote answered a protocol handshake (not probed yet, unreachable, or local-only)

### 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: calculate_hexagram (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); analyze_location (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); search_articles (readOnlyHint, destructiveHint, idempotentHint, openWorldHint)
- pass `tools.token_cost`: about 435 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: 67 (weight 15)

- pass `deps.known_vulns`: no known advisory in 98 resolved packages
- fail `deps.mcp_sdk_version`: @modelcontextprotocol/sdk 1.30.1 has 1 known advisory (GHSA-6qxp-vccf-f47h); update @modelcontextprotocol/sdk to 1.31.0 or later
- pass `deps.resolvable`: yiditu-mcp@1.1.0 resolved: 98 packages

- tools: 3, about 435 tokens to load them all
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.kingbbs/yiditu-mcp.svg)](https://protogrid.dev/servers/io.github.kingbbs/yiditu-mcp)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.
