## Trust

- hygiene: 100
- liveness: 100
- freshness: 85

- drivers: +repository +namespace-matches-repo +reachable +uptime-100% ~updated-62d-ago
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 86/100 (good)

### protocol: 88 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- warn `protocol.list_ttl`: tools/list carries no ttlMs, so clients re-fetch it

### 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: create_server (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); register_operator (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_operator_info (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 1,355 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: 100 (weight 15)

- pass `deps.known_vulns`: no known advisory in 73 resolved packages
- pass `deps.mcp_sdk_version`: mcp 2.2.0, no known advisory
- pass `deps.resolvable`: mcp-billing-gateway@0.1.2 resolved: 73 packages

- tools: 12, about 1,355 tokens to load them all
- tool set hash: 92990112be69a9f2e77049c496af2a54
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.sapph1re/mcp-billing-gateway.svg)](https://protogrid.dev/servers/io.github.sapph1re/mcp-billing-gateway)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.
