How are credentials and API keys handled?

Connection strings and API keys are set as environment variables in the Cursor AI MCP configuration file (`~/.cursor/mcp.json`). The README warns never to commit these keys to version control.

All in one place for my MCP servers Confirm the tools offered by your installed version in the connected client. Tool availability and permissions depend on the server and account configuration.

What credentials does it need?

It reads `PG_DB_MAP`, `OBSIDIAN_API_KEY`, `N8N_BASE_URL`, `N8N_API_KEY`, `GEMINI_API_KEY` from the environment. Store these in your client's env block or a secrets manager — never commit them to a repository — and grant the narrowest scope that still covers your use case.
