## Quality 91/100 (strong)

### protocol: 75 (weight 25)

- 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)

- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 20 of 20 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 2,045 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: 20, about 2,045 tokens to load them all
- tool set hash: 582384b582738215dae2217eeccc4b4f
- badge: [![protogrid quality](https://protogrid.dev/badge/xyz.chainverdict/chainverdict.svg)](https://protogrid.dev/servers/xyz.chainverdict/chainverdict)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.
