## 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**: 71/100
  - Repository presence not verified: we could not reach the forge to check. This is a gap on our side, not a finding about the repository.
  - Cryptographically verified build provenance (signed, bound to pipeworx-io/mcp-climate).
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 5 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 65/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 287 tokens (~143/item across 2 items; 2 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 23/100
  - Stability observed for 7 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **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 2 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 3 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.

## MCP tools (2)

### `get_climate_projection` (~120 tokens)

Get historical and future temperature and precipitation projections for a location (1950–2050). Returns daily forecasts with temperature, precipitation, and weather conditions.

Input parameters:

- `end_date` (string, required): End date in YYYY-MM-DD format (must be between 1950 and 2050).
- `latitude` (number, required): Latitude of the location in decimal degrees.
- `longitude` (number, required): Longitude of the location in decimal degrees.
- `start_date` (string, required): Start date in YYYY-MM-DD format (must be between 1950 and 2050).

### `compare_models` (~116 tokens)

Compare temperature projections across climate models for the same location and date range. Returns side-by-side daily mean temperatures to assess model agreement and uncertainty.

Input parameters:

- `end_date` (string, required): End date in YYYY-MM-DD format (must be between 1950 and 2050).
- `latitude` (number, required): Latitude of the location in decimal degrees.
- `longitude` (number, required): Longitude of the location in decimal degrees.
- `start_date` (string, required): Start date in YYYY-MM-DD format (must be between 1950 and 2050).

## Common questions

### What is the Climate MCP server?

Climate is an MCP server listed in the public MCP registry as io.github.pipeworx-io/climate. Climate MCP, wraps Open-Meteo Climate API (free, no auth). This page covers its npm package (@pipeworx/mcp-climate).

### Is the Climate MCP server safe to use?

Climate scores 77 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 Climate MCP server expose?

Climate exposes 2 tools: get_climate_projection, compare_models. Their descriptions and schemas cost roughly 236 tokens of context every time the server is loaded.

### Is the Climate MCP server still maintained?

Climate 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 Climate MCP server under?

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

### What did VerifyMCP test on the Climate MCP server?

VerifyMCP ran 15 checks on Climate, covering Malware scan, Known CVEs, Install scripts, Dependency health and 11 more. One item could not be completed, a gap on our side rather than a finding about Climate: Provenance. Endpoint Security and Transport & Reachability do not apply to an npm package, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
