## 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: get_tourism_preflight (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_evidence_pack (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); search_rules (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 924 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: 7, about 924 tokens to load them all
- tool set hash: d66d4a9e284de74eb7789d3b9b9c7e1d
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.kadopi/japan-rulewatch-mcp.svg)](https://protogrid.dev/servers/io.github.kadopi/japan-rulewatch-mcp)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (7)

- `get_commercial_terms`: Free: return the current business-only commercial terms profile for a supported paid product. A status other than ready means Mainnet purchase is unavailable.
- `get_entry_pack`: Paid: return the fixed Iya soba entry-preparation pack with sources, contacts, consultation text, unknowns, and next actions. It gives no customer-specific legal verdict. Japan Rule is not a government service.
- `get_evidence_pack`: Return a concise evidence pack for one rule ID returned by search_rules. Includes official URLs, scope limits, and no legal-compliance verdict.
- `get_tourism_evidence_pack`: Paid: return official Japanese primary-source URLs, evidence locations, checked dates, source versions, general requirements, traveler-screen checks, and re-check triggers for a complete supported A/B/C flow. This is informational evidence, not a legal verdict.
- `get_tourism_preflight`: Free: classify a Japan-bound hotel service flow into the supported A/B/C model, list missing facts, and flag manual review. It does not return primary-source evidence.
- `search_entry_cases`: Free: search the fixed Japan tourism entry-case catalog by region, activity, and language. Returns a model-case preview, key decision themes and what the paid preparation pack adds. It does not include source locations, contact routes, inquiry text or an action plan. Japan Rule is a private commercial service, not a government service.
- `search_rules`: Search a small curated index of official Japanese sources about mail-order sales advertising. Use this before get_evidence_pack. Results are evidence pointers, not legal conclusions.
