Overview

AI-generated overview

A small local MCP server that lets an assistant convert values between units of length, mass, temperature and data size, and list supported units.

What you can do
  • Convert a value from one unit to another across length, mass, temperature and data size
  • List the units the server supports
When to use it
Useful when you want an assistant to do quick, exact unit conversions without relying on its own arithmetic, for example turning measurements or file sizes into another unit.
Requirements
Runs as a local process via npx (Node.js), started with the package proofmark-units. No accounts, API keys, environment variables or network access are needed.
Before you install
The README states it is pure computation: it reads no files, opens no network connections and stores nothing. It only covers length, mass, temperature and data size, so other unit types are out of scope.

Installation

In SourceWeft

  1. Open Proofmark Units in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

Score

40% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.

  • Tools listed15 pts

    Answer tools/list without a credential, or ship a package that starts in a sandbox without one.
