What is the Braintrust MCP Server?
Connect your Braintrust AI observation platform to any agent and maintain intense logic evaluation capabilities directly over conversation.
What you can do
- Project Analytics — Retrieve logic banks and branch isolated AI test sets
- Experiments — Create real trace regression tests appending unique LLM scoring iterations
- Datasets — Query accurate Ground Truth sets and insert new prompt templates mapping your system accuracy
- Prompt Versioning — Grab perfectly frozen semantic prompts without editing core code boundaries
How it works
- Add this server to your AI cluster
- Bind your personal Braintrust API ID variables
- Leverage complex model tuning pipelines querying native AI logic regressions on chat
Automate LLM regression analyses effortlessly. Rather than scrolling tables, your bot handles strict semantic checking via Braintrust infrastructure logic directly.
Who is this for?
- AI Developers — push Ground Truth evaluation text datasets on the fly testing prompt differences
- Machine Learning Engineers — track specific variable distributions checking accurate regressions remotely
- Product Teams — observe exact string prompts dynamically pushing features validating response styles
- Data Scientists — construct massive matrices and evaluate test runs without pulling script queries
Built-in capabilities (10)
Establish a new historical experiment trace to record LLM pipeline tests
Create a new project environment for tracking AI evaluations and datasets
Retrieve a specific dataset containing exact schemas bounding LLM outputs
Retrieve exact variable contexts and literal text templates for a prompt
Append new test cases into a dataset matrix targeting specific evaluations

Why VS Code Copilot?
GitHub Copilot Agent mode brings Braintrust data directly into your VS Code workflow. With a project-scoped config, the entire team shares access to 10 tools. Copilot queries live data, generates typed code, and writes tests from actual API responses, all without leaving the editor.
- —
VS Code is used by over 70% of developers. adding MCP tools to Copilot means your team can leverage external data without leaving their primary editor
- —
Project-scoped MCP configs (
.vscode/mcp.json) let you commit server configurations to your repository, ensuring the entire team shares the same tool access - —
Copilot's Agent mode integrates MCP tools seamlessly with file editing, terminal commands, and workspace search in a single agentic loop
- —
GitHub's enterprise compliance and audit features extend to MCP tool usage, providing visibility into how AI interacts with external services

Frequently asked questions
Can I insert new test data dynamically tracking specific limits?
Yes. Utilizing the insert_dataset_row method, you can effortlessly inject exact JSON tracking payload mapping strings directly inside the text corpus evaluating the final results.
Does it pull out original Prompt definitions stored securely?
Certainly. The get_prompt command isolates and returns perfectly version-controlled bounding parameters slicing literal templates natively hosted under the Braintrust database.
How deeply can it inspect test regressions or scoring limits?
Using the robust list_experiments call, you can branch full arrays separating LLM version behaviors over massive iterations tracking the performance anomalies accurately.
Which VS Code version supports MCP?
MCP support requires VS Code 1.99 or later with the GitHub Copilot extension. Ensure both are updated to the latest version. Older versions of Copilot may not expose the Agent mode toggle.
How do I switch to Agent mode?
Open the Copilot Chat panel and look for two mode options: "Ask" and "Agent". Click "Agent" to enable autonomous tool calling. In Ask mode, Copilot provides conversational answers but cannot invoke MCP tools.
Can I restrict which MCP tools Copilot can access?
Yes. VS Code shows a tool consent dialog before any MCP tool is invoked for the first time. You can also configure tool access policies at the organization level through GitHub Copilot settings.
Does MCP work in VS Code Remote or Codespaces?
Yes. MCP servers configured via .vscode/mcp.json work in Remote SSH, WSL, and GitHub Codespaces environments. The MCP connection is established from the remote host, so ensure the server URL is accessible from that environment.
MCP tools not available
Ensure you are in Agent mode in Copilot Chat. MCP tools only appear in Agent mode.
