This Claude plugin automatically sets up a Braintrust MCP connection. The connection reads the `BRAINTRUST_API_KEY` environment variable to establish the MCP connection.
Diagnoses and fixes MCP server connection issues between Claude Code, Claude Desktop, and MCP servers. Covers Windows argument parsing, authentication failures, transport issues, and platform-specific debugging.
Guides MCP server integration into Claude Code plugins via .mcp.json or plugin.json, covering stdio, SSE, HTTP for external tools like filesystems and APIs.
Handles Claude Code MCP integration: installs/manages servers (HTTP/SSE/stdio), scopes, enterprise configs, OAuth auth, resources/@mentions, prompts, limits, security; delegates to docs-management.

Run echo $BRAINTRUST_API_KEY to check if the variable is exported
API keys can be created at https://www.braintrust.dev/app/settings?subroute=api-keys
Test the key by calling the Braintrust API:
curl -s https://api.braintrust.dev/api/self/me -H "Authorization: Bearer $BRAINTRUST_API_KEY"
NOTE: Even if you can curl the api via http, continue to attempt MCP setup. Http is just a troubleshooting tool, not a replacement for MCP
If the key is valid but connection still fails, check if the MCP server is up:
curl -s -o /dev/null -w "%{http_code}" https://api.braintrust.dev/mcp
