## Quality 100/100 (strong)

### protocol: 100 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- pass `protocol.list_ttl`: tool list is cacheable (ttlMs 3600000)

### 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: 100 (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
- pass `tools.annotations`: 2 of 2 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 372 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: 2, about 372 tokens to load them all
- tool set hash: 5f7046a09fbe829c3418149a0c262085

## Tools (2)

- `get_example_number`: Return the libphonenumber example (mobile) number for a region, in all formats, for format testing only (do not dial). Read-only. Same data and limits as GET /v1/example/{country}.
- `parse_phone_number`: Validate one phone number offline against libphonenumber metadata and return E.164, international, national and RFC 3966 formats, region, calling code and line type (from the original allocation). Valid means the number fits an allocated range, not that the line is connected or reachable; no carrier/HLR lookup. Read-only. Same engine, keys and limits as POST /v1/parse.
