## Tools

7 declared. Statically extracted from the shipped source — a floor on the surface, not a census.
- `search_catalog`
- `query_atmosphere`
- `diagnose_atmosphere`
- `compare_runs` — Compare forecast initialization cycles for GFS, GEFS, deterministic ECMWF IFS, or ECMWF IFS ENS through one dataset-aware contract. Deterministic GFS and IFS re
- `compare_datasets`
- `verify_forecast`
- `find_analogs` — Find locally materialized historical analyses similar to one target atmospheric profile. The current dataset is gfs-analysis; similarity uses the existing stand

## Install

**Verdict: install** — No blocking findings and no open coverage gaps — safe to install as configured.
**Config** (claude-code):
```json
"{\n  \"mcpServers\": {\n    \"weather-for-grown-ups\": {\n      \"command\": \"npx\",\n      \"args\": [\n        \"-y\",\n        \"weather-for-grown-ups\"\n      ]\n    }\n  }\n}"
```

## Blast radius

Contained to moderate — no credential declaration found, from the publisher, the upstream registry, or the README. Known so far: runs on your machine; read-only tool surface.
- Floor 12, ceiling 30 (tier: unknown)
- `unknown` means the floor and ceiling land in different bands — not measured enough to name one. It does not mean low.
- This is impact, not likelihood. A high radius is not a defect: a filesystem server is supposed to write files. It is never part of the trust score.
