## Quality 91/100 (strong)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-11-25; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- 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)

- 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`: 3 of 3 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 1,130 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: 3, about 1,130 tokens to load them all
- tool set hash: 34193113a0849d3f881b7327627defff
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.rccaoki-wq/license-guard.svg)](https://protogrid.dev/servers/io.github.rccaoki-wq/license-guard)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (3)

- `check_dependency_license`: Determine whether adding or keeping a single open source dependency creates a legal obligation, given how this project ships. Call this BEFORE adding a new dependency to a project, and when auditing an existing one. A permissive result means no source-disclosure duty; a blocked result means the license obligates you and the dependency should be replaced or the shipping model reconsidered.
- `check_manifest_licenses`: Scan an entire dependency manifest and report every dependency whose license creates an obligation for this shipping model. Use when reviewing a project as a whole, preparing for due diligence, or after a large dependency change. Pass a package-lock.json when one exists: problematic licenses usually arrive as transitive dependencies rather than ones you added directly, and only a lockfile reveals those.
- `explain_license`: Given an SPDX license identifier or expression, explain what it requires across every shipping model at once. Use when the question is about the license itself rather than a specific package — for example when comparing AGPL-3.0 against GPL-3.0 for a hosted service, or deciding what a project may safely depend on.
