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

Why Pydantic AI?
Pydantic AI validates every Weights & Biases tool response against typed schemas, catching data inconsistencies at build time. Connect 6 tools through Vinkius and switch between OpenAI, Anthropic, or Gemini without changing your integration code. full type safety, structured output guarantees, and dependency injection for testable agents.
- —
Full type safety: every MCP tool response is validated against Pydantic models, catching data inconsistencies before they reach your application
- —
Model-agnostic architecture. switch between OpenAI, Anthropic, or Gemini without changing your Weights & Biases integration code
- —
Structured output guarantee: Pydantic AI ensures tool results conform to defined schemas, eliminating runtime type errors
- —
Dependency injection system cleanly separates your Weights & Biases connection logic from agent behavior for testable, maintainable code

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 Pydantic AI discover MCP tools?
Create an MCPServerHTTP instance with the server URL. Pydantic AI connects, discovers all tools, and generates typed Python interfaces automatically.
Does Pydantic AI validate MCP tool responses?
Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.
Can I switch LLM providers without changing MCP code?
Absolutely. Pydantic AI abstracts the model layer. your Weights & Biases MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
