Primary DeepSeek V4.1 chat tool for text, images, and multi-turn generation. Defaults to deepseek-flash. Provide either message (a text string or text/image/file content parts) or messages (full chat history); if both are provided, messages is used. Images may use an HTTP(S) URL, supported base64 data URL, or Files API file_id. Thinking is enabled by default; use reasoning_effort for current effort controls. Use conversation_id for explicit in-memory context. Set include_raw_response=true only for provider-payload debugging.

DeepSeek FIM completion tool for prompt/suffix fill-in-the-middle workflows. Defaults to deepseek-flash in non-thinking mode. 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.

Create a stateless DeepSeek V4.1 response using the OpenAI-compatible Responses API. Defaults to deepseek-flash and accepts text, image URLs, base64 images, and Files API file_id inputs. Use reasoning.effort for thinking control, tools for function or server-side web-search tools, and stream=true for semantic SSE aggregation. Send full input history for multi-turn work. Set include_raw_response=true only for provider-payload 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.

Upload a JPEG, PNG, GIF, or WebP image to DeepSeek and return a reusable file_id. Supply base64 image data directly; server-local file paths are intentionally not accepted. Optional expiry is 3,600 to 2,592,000 seconds.

List images uploaded to the DeepSeek Files API. Supports cursor pagination, creation-time order, and the user_data purpose filter.

Retrieve metadata for one DeepSeek Files API image by file_id.

Delete one uploaded DeepSeek image by file_id. This permanently removes that provider-side file reference.

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.
