## Connection (mcpServers)

```json
{
  "mcpServers": {
    "au-business-identity": {

## Trust

- hygiene: 100
- liveness: 28
- freshness: 100
- provenance: 80
- drivers: +repository +namespace-matches-repo -unreachable(1 failures) +updated-7d-ago
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 83/100 (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 declares ttlMs 0, so clients re-fetch it on every use

### 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: verify_abn (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); validate_acn (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); validate_abn (readOnlyHint, destructiveHint, idempotentHint, openWorldHint)
- pass `tools.token_cost`: about 300 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: n/a (weight 15)

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

- tools: 3, about 300 tokens to load them all
- tool set hash: 4e2117461f0ec079e2ade39dd5370f82
- tools last changed: 2026-10-14T05:27:05.922Z
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.creatorhub121/au-business-identity.svg)](https://protogrid.dev/servers/io.github.creatorhub121/au-business-identity)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.
