About Braintrust MCP Server
Connect your Braintrust AI observation platform to any agent and maintain intense logic evaluation capabilities directly over conversation.
Windsurf's Cascade agent chains multiple Braintrust tool calls autonomously. query data, analyze results, and generate code in a single agentic session. Paste Vinkius Edge URL, reload, and all 10 tools are immediately available. Real-time tool feedback appears inline, so you see API responses directly in your editor.
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
The Braintrust MCP Server exposes 10 tools through the Vinkius. Connect it to Windsurf in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.

Why Use Windsurf with the Braintrust MCP Server
Windsurf provides unique advantages when paired with Braintrust through the Model Context Protocol.
Windsurf's Cascade agent autonomously chains multiple tool calls in sequence, solving complex multi-step tasks without manual intervention
Purpose-built for agentic workflows. Cascade understands context across your entire codebase and integrates MCP tools natively
JSON-based configuration means zero code changes: paste a URL, reload, and all 10 tools are immediately available
Real-time tool feedback is displayed inline, so you see API responses directly in your editor without switching contexts
Braintrust + Windsurf Use Cases
Practical scenarios where Windsurf combined with the Braintrust MCP Server delivers measurable value.
Automated code generation: ask Cascade to fetch data from Braintrust and generate models, types, or handlers based on real API responses
Live debugging: query Braintrust tools mid-session to inspect production data while debugging without leaving the editor
Documentation generation: pull schema information from Braintrust and have Cascade generate comprehensive API docs automatically
Rapid prototyping: combine Braintrust data with Cascade's code generation to scaffold entire features in minutes
