How to Use the Braintrust MCP in Cline

Q: How does Cline handle Braintrust prompt versioning?

Cline uses getprompt to fetch the exact prompt text and variables. It then writes code to integrate these templates into your local application.

Q: Can Cline create a new Braintrust project?

Yes, Cline calls createproject to establish the project. It then sets up your local configuration files to point to this new environment.

Q: How do I feed test cases to Braintrust from Cline?

Cline runs insertdatasetrow to append new evaluation rows. It parses your local test failures and registers them as new evaluation targets.

Q: Can Cline view my gateway configurations?

The agent runs listenvvars to inspect API routes. This helps Cline debug connection issues with your LLM providers.

Let Cline build your evaluation pipelines and update Braintrust datasets via this MCP Server.

Cline builds Braintrust projects end-to-end

The `create_project` tool lets Cline set up a brand-new evaluation environment inside your workspace using this MCP connection. The agent initializes the workspace, writes the test runner, and links it to the newly created project in one shot. Cline doesn't just show you commands; it executes them. It creates the files, configures the environment, and verifies the connection to ensure your evaluation workspace is fully functional.

Sync ground truth data via Cline MCP Server

The `list_datasets` tool pulls your ground truth text banks directly into VS Code. Cline reads these schemas to write local integration tests that match your production evaluation criteria. If a test schema changes, Cline updates your local files to align. You get instant feedback on whether your local code changes will break your remote evaluations.

Run and log experiments with Cline

The `list_experiments` tool lets Cline fetch historical evaluation scores to compare them against your current local runs. The agent runs your test suite, checks the delta, and writes a markdown summary of the performance shift. This gives you a clear picture of regression risks. Cline handles the execution and comparison, so you only review the final diff.
