Category Maps and Location
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. How we score → Why this is hard to score →
Supply Chain Security100
- No malware found by supply-chain analysis.Pass
- No known CVEs affecting this package version or its production dependencies.Pass
- No install/post-install scripts declared.Pass
- No production dependencies, so there is no dependency health to assess. View diagnostics → Pass
Provenance & Transparency97
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Cryptographically verified build provenance (signed, bound to pipeworx-io/mcp-weather-gc-ca). View diagnostics → Pass
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 6 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability64
- AI-judged instruction clarity (good).Pass
- 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. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management0
- Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 6 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 7 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
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.
Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
active_alerts ~141
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.
| Name | Type | Req | Description |
|---|---|---|---|
| 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). |
No output schema declared.
No examples provided.
climate_daily ~173
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.
| Name | Type | Req | Description |
|---|---|---|---|
| climate_id | string | yes | ECCC climate identifier, e.g. "6158355" (TORONTO CITY). |
| end_date | string | yes | End date YYYY-MM-DD, e.g. "2026-05-07". Max 50 days returned. |
| start_date | string | yes | Start date YYYY-MM-DD, e.g. "2026-05-01". |
No output schema declared.
No examples provided.
current_observations ~136
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.
| Name | Type | Req | Description |
|---|---|---|---|
| latitude | number | yes | Latitude in decimal degrees, e.g. 43.65 (Toronto). |
| limit | number | – | Max observations to return (default 5, max 20). |

geomet_collections ~158
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.
| Name | Type | Req | Description |
|---|---|---|---|
| limit | number | – | Max collections to return (default 30, max 150). |

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.
| Name | Type | Req | Description |
|---|---|---|---|

hydrometric_stations_near ~285
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.
| Name | Type | Req | Description |
|---|---|---|---|
| latitude | number | – | Latitude in decimal degrees, e.g. 43.65 (Toronto). |
