Braintrust has introduced the Model Context Protocol (MCP) server, an open standard by Anthropic, designed to enhance AI tools' access to external data sources securely. This server seamlessly integrates Braintrust data with popular AI coding tools, improving the workflow by providing insights into an application's structure and performance without the need for frequent context switching. The MCP enables AI tools to naturally query experiments, debug failures, access contextual documentation, and compare model performances, thus eliminating the need for custom evaluation infrastructure. Supported by various AI coding tools like Cursor, Claude Code, VS Code, and Windsurf, the MCP ensures secure data handling through OAuth 2.0 and supports self-hosted instances to keep data within a user's infrastructure. Once integrated, AI assistants gain capabilities like semantic search, object resolution, schema analysis, and more, allowing them to understand the user's project context and access data directly to enhance the evaluation workflow.
