When does this happen?

IF Storing raw API keys or secrets directly in MCP server configuration within MetaMCP can lead to credential exposure in version control.

How others solved it

THEN Use environment variable references with ${VAR_NAME} syntax instead of raw values. Set the actual secret values in the MetaMCP container's environment variables. This keeps secrets out of configuration files and git repositories.

Before: "API_KEY=sk-..."
After: "API_KEY=${OPENAI_API_KEY}"
