process.env. You'll be asked to provide them before it can run.API_BASE_URL— "": "http://localhost:1234/v1",API_KEY— Universal compatibility — works with MCP sampling (Claude Desktop) or direct LLM HTTP calls (OpenAI, LMStudio, Ollama, any OpenAI-compatible API). Set to use direct mode.BASE_TEMP— 0.1 Initial sampling temperature.CACHE_MAX_ENTRIES— 100 Maximum cached results before evicting oldest.CACHE_TTL— 3600000 Result cache TTL in ms (default 1 hour). Set to 0 to disable.COT_PARSERS— (all) Comma-separated parser names to use (e.g., direct-json,fenced-block). Skips others.FALLBACK_MODELS— (not set) Comma-separated list of fallback models (e.g. gpt-4o,claude-3-5-sonnet). Cycled on failure.LOG_LEVEL— Structured logging — timestamped, level‑filtered logs to stderr (supports ).MAX_RETRIES— 2 Number of retry attempts before returning raw output.MODE— "": "direct",MODEL— "": "gemma-4-e4b-it-mlx"REASONING_OVERHEAD— Token budgeting with tiktoken — accurate token counting using OpenAI's cl100k_base encoding, with fallback to character heuristic. Tweak via .TIMEOUT— 60000 / 120000 Sampling timeout in ms (60s). Direct HTTP mode uses longer default (120s) since local models are slower.TRUNCATION_THRESHOLD— Output truncation detection — detects when the LLM response hits the token limit and retries with a conciseness hint ().[](https://m8ven.ai/mcp/islobodan-cotforce-mcp-ojtqwf)
