Primary DeepSeek V4 chat tool for single-turn and multi-turn generation. Defaults to deepseek-v4-flash; use deepseek-v4-pro for higher-capability reasoning. Provide either message (simple single user turn) or messages (full chat history); if both are provided, messages is used. Thinking mode is enabled by DeepSeek by default; pass thinking:{type:"disabled"} for non-thinking mode, and use reasoning_effort:"high"|"max" when thinking is enabled. Use conversation_id to persist context across calls and clear_conversation=true to reset stored state before sending the next turn. Set include_raw_response=true only for debugging because it returns the full provider payload.

DeepSeek V4 Pro FIM completion tool for prompt/suffix fill-in-the-middle workflows. Defaults to deepseek-v4-pro. Use this when you need raw completion text instead of chat message formatting. Set include_raw_response=true only when you need the full provider payload for debugging.

List available DeepSeek models for model selection and validation. This tool takes no parameters. Use it before passing an explicit model ID to generation tools.

Return the current DeepSeek account balance and availability status. This tool takes no parameters and is read-only. Use it for account health checks when diagnosing provider-side failures.

Delete stored in-memory chat history for a conversation_id. Use this when you want to keep the same ID but start a fresh thread. This only affects server-side memory in the current MCP process.

List all conversation IDs currently stored in this MCP process memory. This tool takes no parameters and does not call the DeepSeek API. Useful for debugging conversation persistence behavior.
