- `SYSDIG_MCP_LOGLEVEL`: Log Level of the application (`DEBUG`, `INFO`, `WARNING`, `ERROR`). Defaults to: `INFO`
- `SYSDIG_MCP_LISTENING_PORT`: The port for the server when it is deployed using remote protocols (`streamable-http`, `sse`). Defaults to: `8080`
- `SYSDIG_MCP_LISTENING_HOST`: The host for the server when it is deployed using remote protocols (`streamable-http`, `sse`). Defaults to: `localhost`
- `SYSDIG_MCP_LISTENING_HOST`: The host for the server when it is deployed using remote protocols (`streamable-http`, `sse`). Defaults to all interfaces (`:port`). Set to `127.0.0.1` for local-only access.

You can find your API token in the Sysdig Secure UI under **Settings > Sysdig Secure API**. Make sure to copy the token as it will not be shown again.
