## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Supply Chain Security**: 100/100
  - No malware found by supply-chain analysis.
  - No known CVEs affecting this package version or its production dependencies.
  - No install/post-install scripts declared.
  - No production dependencies, so there is no dependency health to assess.
- **Provenance & Transparency**: 97/100
  - Source repository is publicly reachable at the declared URL.
  - Cryptographically verified build provenance (signed, bound to pipeworx-io/mcp-weather-gc-ca).
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 6 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 64/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 1270 tokens (~211/item across 6 items; 6 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 6 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 7 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

**Unverified: 1 category.** A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

First indexed and scored.

## MCP tools (6)

### `current_observations` (~136 tokens)

Latest real-time surface weather observations from Environment Canada stations near a point (swob-realtime). Returns station name, observation time, air temp, dewpoint, humidity, wind, pressure, snow depth. Example: latitude 43.65, longitude -79.38 for Toronto. Keyless, official ECCC data.

Input parameters:

- `latitude` (number, required): Latitude in decimal degrees, e.g. 43.65 (Toronto).
- `limit` (number): Max observations to return (default 5, max 20).
- `longitude` (number, required): Longitude in decimal degrees, e.g. -79.38 (Toronto).

### `active_alerts` (~141 tokens)

Active Environment Canada weather alerts (warnings, watches, statements) across Canada, optionally filtered near a point. Returns alert name, type, risk colour, affected area, province, effective/expiry times and a text excerpt. Example: latitude 43.65, longitude -79.38 for Toronto-area alerts. Keyless, official ECCC data.

Input parameters:

- `latitude` (number): Optional latitude — if both latitude and longitude are given, alerts are filtered to a ±2° box around the point.
- `limit` (number): Max alerts to return (default 10, max 30).
- `longitude` (number): Optional longitude (used with latitude).

### `climate_daily` (~173 tokens)

Daily climate records (max/min/mean temperature °C, total precipitation mm, snow on ground cm) for an Environment Canada station over a date range. Use a 7-digit climate identifier, e.g. "6158355" (TORONTO CITY) or "1108395" (VANCOUVER INTL A). Station IDs come from the climate-stations collection. Keyless, official ECCC data.

Input parameters:

- `climate_id` (string, required): ECCC climate identifier, e.g. "6158355" (TORONTO CITY).
- `end_date` (string, required): End date YYYY-MM-DD, e.g. "2026-05-07". Max 50 days returned.
- `start_date` (string, required): Start date YYYY-MM-DD, e.g. "2026-05-01".

### `geomet_collections` (~158 tokens)

Directory of every dataset Environment and Climate Change Canada publishes through MSC GeoMet (100+ OGC API Features collections). Returns each collection id, title, description, keywords and geographic extent. Use it to find what Canadian weather, water, air-quality or climate-projection data exists and what its collection id is, before reaching for a purpose-built tool. Example: search "hydrometric" for river gauge datasets, "cmip5" for climate projections, "swob" for surface observations.

Input parameters:

- `limit` (number): Max collections to return (default 30, max 150).
- `search` (string): Case-insensitive substring matched against collection id, title, description and keywords, e.g. "hydrometric".

### `hydrometric_stations_near` (~285 tokens)

Water Survey of Canada river and lake gauges near a point, from the MSC GeoMet hydrometric-stations collection. AUTHORITATIVE for "which gauge measures the <Canadian river> at <place>" — these are the official federal hydrometric stations. Returns station number (the id you pass to hydrometric_realtime), station name, province, active/discontinued status, gross drainage area in km2, whether it reports in real time, and coordinates. Example: latitude 43.65, longitude -79.38 for Toronto-area gauges.

Input parameters:

- `latitude` (number): Latitude in decimal degrees, e.g. 43.65 (Toronto).
- `limit` (number): Max stations to return (default 20, max 100).
- `longitude` (number): Longitude in decimal degrees, e.g. -79.38 (Toronto).
- `province` (string): Optional two-letter province or territory code, e.g. "ON", "BC", "QC".
- `radius_deg` (number): Half-width of the search box in degrees (default 0.5, max 5). 0.5 deg is roughly 55 km north-south.
- `real_time_only` (boolean): When true, return only stations that report in real time (the ones hydrometric_realtime can serve). Default false.

### `hydrometric_realtime` (~321 tokens)

Real-time water level (metres) and discharge/flow (m3/s) readings from Water Survey of Canada gauges, typically every 5-15 minutes and covering the last 30 days. AUTHORITATIVE for "how high is the <Canadian river> right now" and for flood watching in Canada. Pass a station number from hydrometric_stations_near, e.g. "02HC003" (HUMBER RIVER AT WESTON), or give latitude/longitude to get the most recent readings from every real-time gauge in the area. Readings come back newest first.

Input parameters:

- `end_date` (string): Optional end of the time window, YYYY-MM-DD, e.g. "2026-09-17".
- `latitude` (number): Latitude, used instead of station_number to sweep an area, e.g. 43.65.
- `limit` (number): Max readings to return (default 20, max 200).
- `longitude` (number): Longitude, used with latitude, e.g. -79.38.
- `radius_deg` (number): Half-width of the area sweep in degrees (default 0.5, max 5).
- `start_date` (string): Optional start of a time window, YYYY-MM-DD, e.g. "2026-09-10". Data goes back 30 days.
- `station_number` (string): Water Survey of Canada station number, e.g. "02HC003". Get one from hydrometric_stations_near.

Weather Gc Ca is an MCP server listed in the public MCP registry as io.github.pipeworx-io/weather-gc-ca. Environment and Climate Change Canada (ECCC) GeoMet MCP. This page covers its npm package (@pipeworx/mcp-weather-gc-ca).

### Is the Weather Gc Ca MCP server safe to use?

Weather Gc Ca scores 79 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Weather Gc Ca MCP server expose?

Weather Gc Ca exposes 6 tools: current_observations, active_alerts, climate_daily, geomet_collections, hydrometric_stations_near, hydrometric_realtime. Their descriptions and schemas cost roughly 1,214 tokens of context every time the server is loaded.

### Is the Weather Gc Ca MCP server still maintained?

Weather Gc Ca is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the Weather Gc Ca MCP server under?

Weather Gc Ca declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
