# Logging & Tracing ## Log Levels - `MCP_LOG_LEVEL`: `debug` | `info` | `warn` | `error` | `silent` (default `warn`). - `DEBUG`: enable debug logs by namespace; set to `swipl-mcp-server`. ## Wire/Child Tracing - `SWI_MCP_TRACE`: optional low‑level tracing of the spawned Prolog process (stdout/stderr) and protocol frames. ## Notes - Logs initialize early to help diagnose startup issues. - Prefer structured logs (`MCP_LOG_LEVEL`) for normal operation; enable `SWI_MCP_TRACE` only for deep debugging.
