How to Use the Braintrust MCP in VS Code Copilot

Q: How do I share the Braintrust MCP Server with my team in VS Code Copilot?

Create a .vscode/mcp.json file in your repository root and define the MCP configuration. Once committed to Git, any team member running VS Code 1.96+ with Copilot can use the Braintrust tools.

Q: Can VS Code Copilot run Braintrust experiments?

Yes, Copilot invokes createexperiment to start a new evaluation trace. It tracks metrics and logs scores directly from the terminal, comparing your active branch against historical experiments.

Q: How does VS Code Copilot access Braintrust datasets?

Copilot uses listdatasets to locate your ground truth text banks. It then pulls specific schemas using the getdataset tool to guide its code generation.

Q: Does this integration expose my Braintrust gateway keys?

No, the server uses listenvvars to manage model API configurations securely. Your keys are handled within the IT-managed VS Code environment to prevent accidental exposure in public repos.

Share Braintrust evaluation workflows across your team with VS Code Copilot configuration files.

Standardize Braintrust projects for VS Code Copilot teams

This MCP Server implements `list_projects` and `create_project` to align your entire development team around shared evaluation spaces inside VS Code Copilot. By committing the server configuration to your repository, every engineer on your team gains access to the same project environments. This setup eliminates configuration drift across team members. Your developer team queries the same central project IDs directly from the Copilot Chat panel, maintaining consistency across local and CI evaluation runs.

Append local edge cases to Braintrust datasets

The `insert_dataset_row` and `get_dataset` tools let VS Code Copilot users contribute to shared ground truth matrices. When a developer encounters an unexpected model output, they ask Copilot to insert the row into the team's evaluation dataset. This turns your local editor into a direct feedback loop for production data. Copilot validates the JSON schema of your local test case and pushes it to Braintrust, making it instantly available directly via the active MCP client.

Inspect Braintrust prompts inside VS Code Copilot

The `list_prompts` and `get_prompt` tools fetch your team's version-controlled system prompts directly into Copilot Chat. Developers can inspect prompt templates and verify literal text structures without opening a browser. Copilot uses this context to suggest code changes that perfectly align with your production prompts. This ensures that any local modification to your LLM orchestration code matches the variables defined in Braintrust.

Setup guide

Set up Braintrust MCP in VS Code Copilot

Prerequisites

VS Code 1.99 or later with GitHub Copilot extension
Active Vinkius subscription with a valid endpoint token

1

Open MCP configuration

Open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and run "MCP: Add Server". Select HTTP (Streamable) as the server type. VS Code will create .vscode/mcp.json in your workspace.
2

Add the Braintrust MCP

Paste the JSON snippet shown on the right into your .vscode/mcp.json. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Switch to Agent mode

Open Copilot Chat (Cmd+Shift+I / Ctrl+Shift+I) and switch to Agent mode using the dropdown. MCP tools are only available in Agent mode — they do not appear in Edit or Ask modes.
4

Verify the connection

In the Copilot Chat input, type # to list available tools. You should see the Braintrust tools listed. Try asking: "List my recent Braintrust transactions" and Copilot will invoke them automatically.
