What the code does

Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Builds a database query by concatenation src/dsl/editor/ScriptEditor.tsx:289 
    changes: { from, to, insert },
    selection: EditorSelection.cursor(from + insert.length),

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Available tools 3

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

fluid
fluid_state
A fluid's state from two properties, with CoolProp: T, P, h, s, x, v, and "properties" (D density, u, cp, cv, mu viscosity, k conductivity, Pr, Z, a speed of sound, g). state: "T = 25 °C, P = 1 bar", "P = 1 MPa, sat vapor". Processes and cycles: solve_worksheet.
language
language_reference
The script language's whole manual, for what solve_worksheet's cheat sheet leaves out.
solve
solve_worksheet
Solves processes and whole cycles with CoolProp, written as a Thermoprops Worksheet script. Answers a table of the states, the printed results, errors by line, and a link that opens it solved with diagrams: give it to the user. One statement per line, # comments: fluid R134a units celsius # or kelvin, imperial reference ASHRAE # zero of h, s: DEF, ASHRAE (textbook refrigerant tables), IIR, NBP 1: T = -10 °C, sat vapor # two properties; sat liquid is x = 0 2: from 1, compressed to P = 1.2 MPa, eta = 80% 3: P = P2, sat liquid 4: from 3, throttled to P = P1 COP = (h1 - h4) / (h2 - h1) print COP, T2 in °F, cp2 Processes: isentropic, compressed/expanded (eta), throttled, isobaric, isothermal, isochoric, isenthalpic, polytropic (n).

Thermoprops — questions

Answers built from our own checks of this server.

What can Thermoprops do?
It exposes 3 tools, read directly from the server on our last check. Among them: fluid_state, language_reference, solve_worksheet. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Thermoprops working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 86 of 86 checks got a reply (100.0%), average response time 606 ms. The bar chart above shows every period we have measured.
How do I connect Thermoprops?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Thermoprops need an API key?
No. Thermoprops completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Thermoprops?
It answers our handshake in 606 ms on average, which is faster than 19% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is Thermoprops open source?
The code is open source: it is published under the MIT licence, written in TypeScript and 4 stars on GitHub. The licence covers the code in the repository, not the hosted service at thermoprops-api.luisbedoia.workers.dev, which runs on its operator's own terms.
