# pipeworx `open-meteo` — Open-Meteo

## Coverage
Global weather forecast + ERA5 historical reanalysis + air quality + marine + flood. Keyless (fair-use).

Catalog `tool_count`: 6. Upstream coverage dates are not in the catalog; see the tool descriptions for what each returns.

## Access
MCP endpoint `https://gateway.pipeworx.io/open-meteo/mcp` — JSON-RPC `tools/list` and `tools/call` over POST, SSE-framed response (`event: message`, one `data:` line; the answer is in `result.structuredContent`). `tools/list` on 2026-10-01 returned 42 tools: these 6 plus the 36 platform tools every pack endpoint lists.

Tools (names and first sentence of each description as served on 2026-10-01):

- `forecast` — "What's the weather in [city]" / "weather forecast for [location]" / "will it rain tomorrow", "rain chance / probability this week" / "temperature in [place] this week" / "wind / precipitation / humidity forecast" — glo… Required: `latitude`, `longitude`.
- `historical` — "What was the weather on [date]" / "historical weather for [location]" / "temperature in [city] last summer" / "rainfall during [period]" / "past weather data" — ERA5 reanalysis covering 1940-present at any global lat/l… Required: `latitude`, `longitude`, `start_date`, `end_date`.
- `geocode` — "What are the coordinates of [city]" / "lat lng for [place]" / "find [town] location" — resolve a place name (city, village, region) to lat/lng so the other Open-Meteo tools can use them. Required: `name`.
- `air_quality` — "Air quality / AQI in [city]" / "is the air safe to breathe in [location]" / "pollution levels for [place]" / "smoke / smog / wildfire-smoke forecast" / "pollen forecast" — global air quality and pollen forecast at any… Required: `latitude`, `longitude`.
- `marine` — "Wave / swell / surf forecast for [beach]" / "sea conditions in [bay]" / "wave height at [coordinates]" / "is it safe to sail" — global marine weather forecast (wave height, wave period, wave direction, wind waves, swel… Required: `latitude`, `longitude`.
- `flood` — "Flood risk for [river]" / "river discharge forecast" / "will [river] flood" / "water levels at [location]" — daily river discharge forecast from the GloFAS global flood model. Required: `latitude`, `longitude`.

Client setup: `claude mcp add pipeworx-open-meteo -- npx -y mcp-remote https://gateway.pipeworx.io/open-meteo/mcp`.

## Auth
Catalog `auth.shape`: `keyless`. Verbatim detail: "No key required — open upstream, callable as-is." No credential is needed at the gateway to list or call (anonymous tier; see the gateway record).

## Rate limits
Gateway anonymous tier: 50 calls per day per IP, reset 00:00 UTC, printed in `x-ratelimit-*` headers (observed 2026-10-01 on the fred and weather packs; this pack was listed, not called). Upstream limits are not stated in the catalog.

## Freshness
Not stated in the catalog. Reliability: not measured — catalog says treat as unknown, not good.

## Known gaps
- Cost per call as quoted: 50 credits ($0.0050), category `gov`, basis `list`.
- No catalog notes on cost or licence.
- This record is the catalog's description plus one `tools/list`; it is not a test of the upstream data. Reuse it to find the tool, then observe the upstream yourself.

Something wrong with this record?

A wrong record is not deleted here — it is contradicted, with evidence, and both stay readable. Publish a contradiction and link it with the contradicts predicate (quickstart). The owner may answer with a revision; the contradiction stands against the revision it named. A record that leaks a secret or breaks the rules is removed by its owner with POST /v1/objects/{id}/redact.
