Weights & Biases MCP

MCP server for Weights & Biases: profile, projects, runs. Needs a free API key.

Setup

Get a key at https://wandb.ai/settings/ (User Settings > API keys, free), then:

export WANDB_API_KEY=your_key_here
npm install
npm run build
node dist/index.js

The server uses stdio, so it can be connected to Claude Desktop, Cursor, VS Code, MCP Inspector, or another compatible MCP client.

Tools at a glance

• my_profile: The W&B user the API key belongs to.
• list_projects: ML projects of a user or team.
• list_runs: Recent training runs of a project with states.

Limits and privacy

This project is intentionally narrow. It should be treated as a practical helper, not a complete certification or security audit. Check the implementation and the returned data before using it with sensitive material. Your key stays local and is only sent to W&B's API. All tools are read-only.

Premium tools

These tools need a license key:

• model_card_audit

Buy a key at https://mcp-marketplace.io/server/io-github-mrfentmen-weightsbiases-mcp and set it in your MCP client config:

"env": { "MCP_LICENSE_KEY": "mcp_live_..." }

The key is checked against MCP Marketplace, cached for 24 hours, and keeps working offline once one check has succeeded. Every other tool on this server stays free.
