Bring Machine Learning
to Mastra AI
Create your Vinkius account to connect Weights & Biases to Mastra AI and start using all 6 AI tools in minutes. Fully managed, enterprise secure, and ready to use without writing a single line of code. No hosting, no server setup — just connect and start using.
Compatible with every major AI agent and IDE
What is the Weights & Biases MCP Server?
Connect your Weights & Biases (WandB) account to any AI agent and manage your machine learning experiments through natural conversation.
What you can do
- Project Management — List all projects within your WandB entity (user or team) to browse your experiment folders
- Run Monitoring — List and track individual experiment runs within a project to monitor real-time activity
- Deep Run Analysis — Retrieve full details for any run, including latest accuracies, losses, and hyperparameters
- Artifact Management — List versioned datasets, models, and other artifacts to track data lineage and dependencies
- Sweep Tracking — Monitor automated hyperparameter search sweeps to see optimization progress
- Reports & Collaboration — List saved analysis reports and dashboards to access collaborative documentation
How it works
- Subscribe to this server
- Enter your WandB API Key and optional Base URL
- Start managing your ML experiments through Claude, Cursor, or any MCP-compatible client
No more manual browsing through complex experiment dashboards to check model performance. Your AI agent becomes your ML research assistant.
Who is this for?
- Machine Learning Engineers — monitor model training progress and compare hyperparameters across multiple runs
- Data Scientists — track data lineage and manage versioned artifacts for reproducible research
- Research Teams — collaborate on experiment reports and monitor shared project sweeps through chat
- AI Developers — quickly surface model metrics and experiment summaries for faster development cycles

Frequently asked questions
Can I check the latest metrics for a specific ML run?
Yes. Using the get_run_details tool, your AI agent can pull the latest logged metrics (like accuracy or loss) and hyperparameters for any specific run ID within your projects.
Is it possible to list versioned datasets and models?
Absolutely. The list_project_artifacts tool allows you to see all artifacts, including datasets and models, helping you track data lineage and versioning directly through conversation.
Can I monitor hyperparameter search sweeps via chat?
Yes. Use the list_project_sweeps tool to monitor automated optimization tasks. Your agent will return a list of sweeps in the project so you can track progress without leaving your workspace.
How does Mastra AI connect to MCP servers?
Create an MCPClient with the server URL and pass it to your agent. Mastra discovers all tools and makes them available with full TypeScript types.
Can Mastra agents use tools from multiple servers?
Yes. Pass multiple MCP clients to the agent constructor. Mastra merges all tool schemas and the agent can call any tool from any server.
Does Mastra support workflow orchestration?
Yes. Mastra has a built-in workflow engine that lets you chain MCP tool calls with branching logic, error handling, and parallel execution.
