troubleshoot-braintrust-mcp

This Claude plugin automatically sets up a Braintrust MCP connection. The connection reads the BRAINTRUST_API_KEY environment variable to establish the MCP connection.

Troubleshooting steps

1. Verify the environment variable is set

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

2. Verify the API key is valid

Test the key by calling the Braintrust API:

curl -s https://api.braintrust.dev/api/self/me -H "Authorization: Bearer $BRAINTRUST_API_KEY"

• If valid: returns JSON with user info (id, email, organizations, etc.)
• If invalid: returns an authentication error

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

3. Check if the MCP server is reachable

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

• Any HTTP response (even 401 or 405) means the server is reachable
• Connection timeout or "connection refused" means the server may be down

4. Contact support
