Unit Converter

The Unit Converter MCP provides a set of precise unit-conversion utilities you can access from an MCP client. It lets you convert temperatures, lengths, masses, volumes, times, energies, areas, and more, enabling you to perform quick, accurate calculations within your workflows and tools that integrate MCP servers.

How to use

You connect to the Unit Converter MCP with an MCP client and send requests for conversions. Start by choosing the type of measurement you want to convert, pick the source unit and the target unit, and then supply the numeric value. The MCP handles the rest and returns the converted value. You can chain multiple conversions in a single session to build complex calculations from different unit types.

How to install

Prerequisites: you need a supported environment for MCP clients, typically Node.js for tooling and the MCP runtime. Ensure you have Node and npm or uvx installed as described below.

Step 1: Install the MCP client tooling if you do not already have it.

Step 2: Configure an MCP server connection using one of the available options shown here.

Configuration and running notes

Two ready-to-use MCP connection options are provided for this Unit Converter server. You can run the MCP either via a direct runtime command or through the UVX runtime with a path to the server package.

Remote HTTP connection (default/recommended for centralized MCP management): you can reach the server via a remote endpoint and standard MCP request path. The following STDIO option is available as an alternative if you prefer local execution.

Development and tooling details

The Unit Converter MCP exposes a set of conversion tools you can invoke to perform specific unit conversions. Each tool is designed to handle a particular measurement domain, from temperature to density to speed.

Security considerations

Treat MCP endpoints as you would any external service: use trusted transports, manage access with appropriate credentials, and validate inputs to prevent malformed requests from causing issues in conversions.

Troubleshooting tips

If a conversion fails, ensure your input value is numeric, the from_unit and to_unit strings match the supported unit identifiers, and the MCP server is reachable from your client. Check the active connection, and review any error messages returned by the MCP for clues.

Notes

The Unit Converter MCP supports a broad set of units across multiple domains, including temperature, length, mass, volume, time, energy, area, and more. Use the provided tools to list supported units or to perform direct conversions.
