Category Health and Science
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-coolprop). 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 Usability60
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 580 tokens (~290/item across 2 items; 2 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
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 2 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 3 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 →
coolprop_fluid_properties ~451
Thermophysical properties of a pure fluid, computed from two independent state variables (PropsSI-style — give e.g. temperature + pressure, get density, enthalpy, entropy, viscosity, thermal conductivity, specific heat, phase, ...). Covers ~124 fluids (water, refrigerants, hydrocarbons, cryogens, ...) via CoolProp (open-source, MIT), computed in-process rather than looked up from a table — valid over each fluid's full equation-of-state range, not just tabulated points. No aliases: call coolprop_list_fluids for exact names (e.g. "CarbonDioxide", not "CO2").
| Name | Type | Req | Description |
|---|---|---|---|
| fluid | string | yes | Exact CoolProp fluid name, e.g. "Water", "Nitrogen", "R134a", "CarbonDioxide" — see coolprop_list_fluids for the full list (no aliases) |
| input1_name | string | yes | First independent state variable code: T (temperature, K), P (pressure, Pa), D (mass density, kg/m3), H (mass enthalpy, J/kg), S (mass entropy, J/kg/K), U (mass internal energy, J/kg), or Q (vapor qu… |
| input1_value | number | yes | Value for input1_name, SI units |
| input2_name | string | yes | Second independent state variable code — must differ from input1_name. Same code set as input1_name. |
| input2_value | number | yes | Value for input2_name, SI units |
| outputs | array | yes | Property codes to compute, up to 12 per call: T, P, D (density kg/m3), H (enthalpy J/kg), S (entropy J/kg/K), U (internal energy J/kg), Q (vapor quality), CPMASS (isobaric specific heat J/kg/K), CVMA… |

coolprop_list_fluids ~76
The exact canonical fluid names this CoolProp build recognizes for coolprop_fluid_properties (~124 fluids: water, common refrigerants, hydrocarbons, cryogens, siloxanes, ...). No aliases — e.g. "CarbonDioxide", not "CO2"; use this list rather than guessing a short name.

What is the Coolprop MCP server?
Coolprop is an MCP server listed in the public MCP registry as io.github.pipeworx-io/coolprop. coolprop, thermophysical fluid properties (PropsSI-style: give two independent state variables… This page covers its npm package (@pipeworx/mcp-coolprop).
Is the Coolprop MCP server safe to use?
Coolprop scores 78 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 Coolprop MCP server expose?
Coolprop exposes 2 tools: coolprop_fluid_properties, coolprop_list_fluids. Their descriptions and schemas cost roughly 527 tokens of context every time the server is loaded.
Is the Coolprop MCP server still maintained?
Coolprop 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 Coolprop MCP server under?
Coolprop declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
