au-weather-mcp: Instructions file for Claude Code

CLAUDE.md

au-weather-mcp CLAUDE.md is an instructions file for Claude Code from Bigred97/au-weather-mcp. It costs 1,773 tokens per session, scanned A, a copy of ato-mcp CLAUDE.md, MIT.

Repository instructions for an Australian weather MCP server. It retrieves JSON weather data from Open-Meteo, which aggregates licensed Australian Bureau of Meteorology observations, and resolves Australian postcodes and place names.

In plain words
What is it for?
Use them when developing or reviewing this weather server. They help with weather lookups for Australian cities, regional centres, postcodes, and place names, plus caching, data shaping, and source attribution.
Why use it?
They document the trusted data source, attribution requirements, package structure, and the project-specific modules that must be kept consistent.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

au-weather-mcp CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

84% identical to ato-mcp CLAUDE.md — 44 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Curated datasets (45 cities + AU postcode/place-name lookup)

8 state/territory capitals + 37 regional centres + on-the-fly resolution of any AU postcode or place name

Repo-specific module set

Required (every sister): server.py, models.py, curated.py, client.py, cache.py, shaping.py, data/curated/*.yaml

Repo-specific extras:

  • resolution.py — Australian postcode + place-name fuzzy resolution via OpenStreetMap Nominatim
  • (no parsing.py / discovery.py — Open-Meteo returns clean JSON directly)

Repo-specific gotchas

  • Different response model — uses WeatherResponse not DataResponse. Weather isn't time-series-table-shaped; has current, hourly, daily instead of records. Documented exception to the uniform envelope.
  • Tool names diverge from sister pattern: search_locations / describe_location / get_weather (instead of _datasets / _dataset / get_data).
  • Uses Open-Meteo, NOT direct BOM — BOM 403s non-browser User-Agents and has no documented commercial-use path below their $5k/yr Registered User Service.
  • End-date in the past >5 days routes to Open-Meteo's historical archive (1940+); otherwise routes to forecast endpoint (today + 16 days).

The core 5-tool surface (uniform across sisters — mandatory)

The 5 below are the uniform brand. Additional tools (e.g. top_n, stats) are allowed where the data shape genuinely needs them — they must use the same Annotated[Field] discipline and DataResponse envelope as the core 5.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
