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-climatiq). View diagnostics → Pass
  • Clear OSI-approved license (MIT).Pass
  • Actively maintained (last published 4 days ago).Pass
  • Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability70
  • AI-judged instruction clarity (good).Pass
  • Context-footprint check failed: tool/resource definitions use about 448 tokens (~149/item across 3 items; 3 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 Management23
  • Stability observed for 7 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
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 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
  • An AI judge read all 4 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
Changelog

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.

  • 4 Nov 26 +1

    No change was recorded against any check on this day. Stability & Change Management went from 17 to 20. That category is still filling its 30-day observation window: 5 days of observed history at the previous scan, 6 at this one. The score rises as the window fills, whether or not the server changes.

MCP tools · 3 exposed · ~393 tokens

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 →

Tool Tokens
estimate_emissions ~139

Calculate kgCO₂e for an activity. Pass an emission_factor with at minimum `activity_id` (from search_factors) or `id`, plus the required `parameters` (e.g., `{ energy: 200, energy_unit: "kWh" }`). Returns CO₂e + breakdown.

NameTypeReqDescription
emission_factorobjectyesSelector object — at minimum {activity_id: "..."} or {id: "..."}. May add region, year, source for disambiguation.
parametersobjectyesActivity quantities matching the factor's required unit type (e.g., {energy:200, energy_unit:"kWh"}).

No output schema declared.

No examples provided.

list_unit_types ~30

List supported unit-type families (Energy / Volume / Distance / Mass / etc.) and their valid units.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

search_factors ~224

Search Climatiq's emission-factor database. Use to discover factor IDs and required parameters before calling estimate_emissions. Filter by query, category, source (e.g., "EPA", "DEFRA"), region (ISO code), or year.

Common questions

What is the Climatiq MCP server?

Climatiq is an MCP server listed in the public MCP registry as io.github.pipeworx-io/climatiq. Climatiq MCP, carbon footprint calculator with emission factors. This page covers its npm package (@pipeworx/mcp-climatiq).

Is the Climatiq MCP server safe to use?

Climatiq scores 83 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 Climatiq MCP server expose?

Climatiq exposes 3 tools: search_factors, estimate_emissions, list_unit_types. Their descriptions and schemas cost roughly 393 tokens of context every time the server is loaded.

Is the Climatiq MCP server still maintained?

Climatiq 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 Climatiq MCP server under?
