# Verifreta Carrier Lookup

> Carrier first-look for freight brokers: DOT, MC/MX/FF, and name. SAFER/L&I stay source of truth.

**An agent can connect after a one-time OAuth consent by a human.** Remote endpoint behind OAuth 2. Tokens stay with the agent; the registry only exposes the authorization metadata.

## Quality 86/100 (good)

### 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: 100 (weight 15)

- pass `auth.prm`: Protected Resource Metadata (RFC 9728) published
- pass `auth.as_metadata`: authorization server metadata reachable
- pass `auth.cimd`: Client ID Metadata Documents supported
- 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: get_quota (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); lookup_dot (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); lookup_mc (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 408 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`: 3 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: 4, about 408 tokens to load them all
- tool set hash: 560ad27ea4a19f4b0f325a7fa477ac88
- tools last changed: 2026-09-28T14:19:42.358Z
- badge: [![protogrid quality](https://protogrid.dev/badge/com.verifreta/carrier-lookup.svg)](https://protogrid.dev/servers/com.verifreta/carrier-lookup)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.
