Overview

AI-generated overview

A local MCP server that connects an assistant to Weights & Biases so it can look up profiles, projects and runs.

What you can do
Look up Weights & Biases profiles, projects and experiment runs through the assistant, so it can report on tracked machine-learning work without leaving the conversation.
When to use it
Useful when you track experiments in Weights & Biases and want an assistant to answer questions about your projects and runs while you work.
Requirements
Runs as a local process via the npm package weightsbiases-mcp over stdio, so Node.js is needed. A free Weights & Biases API key is required; the manifest declares no environment variables or headers, so how the key is supplied is not documented here.
Before you install
You must provide a Weights & Biases API key, which grants access to your account's projects and runs; keep it private and check how the server stores or transmits it before installing.

Installation

In SourceWeft

  1. Open Weightsbiases Mcp 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.

25% 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.
