## Quality 78/100 (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: best_bridge_days (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); public_and_school_holidays (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); childcare_gap (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 1,688 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 75 (weight 15)

- warn `stability.changes`: 17 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: 5, about 1,688 tokens to load them all
- tool set hash: a54d86339f0290823feed071cd8fda76
- tools last changed: 2026-10-02T10:26:07.739Z
- badge: [![protogrid quality](https://protogrid.dev/badge/de.urlaub-smart/planner.svg)](https://protogrid.dev/servers/de.urlaub-smart/planner)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

Answers "can we cover the school holidays" for parents.
