Works with Claude, ChatGPT, Cursor, and more

The Model Context Protocol standardizes how applications expose capabilities to LLMs. Instead of operating in isolation, your AI gains direct access to external platforms, live data, and real-world actions through secure, standardized connections.

This connection provides 4 powerful capabilities that interface natively with Claude, ChatGPT, Cursor, and other compatible AI platforms. No middleware. No custom integration required.

Dealing with metric vs. imperial units is a constant pain point.

When you're working on international projects, it’s tedious. You find an old spec sheet that lists pipe diameters in inches, but the new local code requires everything in millimeters. This means opening spreadsheets, cross-referencing unit charts, and manually running conversion formulas—a process ripe for simple decimal mistakes.

With this MCP server, you feed your agent the measurement and tell it to use `convert_length`. The agent handles the math behind the scenes, giving you the precise millimeter value instantly. It’s a direct replacement for that messy, error-prone manual calculation.

The Universal Unit Converter MCP Server gives you mathematical certainty.

You no longer have to worry about whether an AI model is using the right multiplier—is it 1000 for metric, or 1024 for digital storage? The server runs a dedicated engine that knows the difference between `convert_digital_storage` and other tools. It's built specifically for these unit rules.

The math is clean. The output is exact. You get back reliable numbers every time, whether you're checking weights with `convert_weight` or calculating temperatures with `convert_temperature`. That’s the difference.

What your AI can actually do with this

Listen up. You know how general-purpose AI models approximate unit conversions? That's dangerous when you’re doing real math—whether it’s for embedded systems or logistics reports, those guesses can cost you serious money. This MCP Server fixes that mess by routing every calculation through an exact, deterministic JavaScript engine. Your metrics never leave your system; they just get the right number.

When you need to normalize physical dimensions, start with convert_length. You run this tool anytime you gotta switch a dimension from feet to meters, or vice versa, and it guarantees the precise ratio every time. For mass measurements, use convert_weight when you’re reconciling shipment manifests that mix kilograms, pounds, and ounces; it handles both metric (kg, g) and imperial (lb, oz) units so your inventory counts are accurate.

Climate data is complex. If you're building a global report that requires switching between Celsius, Fahrenheit, and Kelvin, the convert_temperature tool takes care of those shifts in one call. Dealing with digital storage capacity—like logging or memory specs—requires convert_digital_storage. This tool specifically manages binary prefixes (B, KB, MB, GB, TB), ensuring it uses the correct 1024 multipliers; you can’t rely on general approximations for that kind of math.

You use these tools to check data integrity across systems. Run any one of them to validate metrics before they enter a database or are incorporated into code generation. The output is pure, verifiable mathematics. It's not writing code; it just gives you the correct number.

Questions you might have

How does convert_digital_storage handle units? +

It uses binary prefixes (B, KB, MB, GB, TB) and specifically employs 1024 multipliers. This is crucial because it prevents the common error of assuming a simple base-10 conversion for memory or file sizes.

Can I use convert_length for any type of distance? +

The convert_length tool handles standard length measurements, including kilometers and miles. It supports both metric units (like meters) and common imperial units (like feet).

Is the conversion done by convert_temperature safe for engineering use? +

Yes. The convert_temperature tool is built using deterministic algorithms to ensure accurate math between Celsius, Fahrenheit, and Kelvin. It's designed for technical precision.

What if I need to convert weight units, which tool should I use? +

You must use convert_weight. This tool is dedicated solely to mass measurements, handling the conversion between kilograms, grams, pounds, and ounces accurately.

Does using `convert_digital_storage` expose my data to external APIs? +

No. The conversion runs 100% locally on your machine. This means there are zero API calls, and sensitive engineering metrics or server logs never leave your environment.

How fast is the calculation when I call `convert_temperature`? +

It delivers zero-latency conversion results. Since it uses deterministic JavaScript algorithms instead of approximation models, you get instant and mathematically guaranteed precision every time.

If my input for weight conversion is malformed, how does the `convert_weight` tool handle errors? +

The engine validates inputs before running calculations. It returns specific error codes or throws a clear exception if the unit or value format isn't recognized, keeping your workflow from breaking.

Is the conversion logic provided by `convert_length` compatible with all major AI clients? +

Yes. This is an open standard MCP Server. Any client that supports the Model Context Protocol—like Cursor or Claude—can invoke these tools directly.

Are digital storage conversions based on base-10 (1000) or base-2 (1024)? +

The digital storage tool strictly uses base-2 (binary multipliers of 1024), which is the standard for memory and file system operations (e.g., 1 KB = 1024 B).

Why use this instead of letting Claude or ChatGPT convert the values? +

LLMs hallucinate subtle decimal errors when converting odd metrics (like 17.3 miles to centimeters). This tool forces the AI to use exact deterministic formulas.

Does it require internet access? +

No. The entire engine is local and executes purely on local hardware without any API requests.
