chat_completion
Primary DeepSeek V4.1 chat tool for text, images, and multi-turn generation. Defaults to the configured model (`deepseek-flash` by default). 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.
completion
DeepSeek FIM completion tool for prompt/suffix fill-in-the-middle workflows. Defaults to the configured model (`deepseek-flash` by default) 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_response
Create a stateless DeepSeek V4.1 response using the OpenAI-compatible Responses API. Defaults to the configured model (`deepseek-flash` by default) and accepts text, image URLs, base64 images, and Files API `file_id` inputs. Use `reasoning.effort` for thinking control, `tools` for functions, the `apply_patch` custom tool, or `web_search` (server-side with `deepseek-v4-pro`, ignored with Flash; provider Search requests may incur separate charges), and `stream=true` for semantic SSE aggregation. Send full input history for multi-turn work. Set `include_raw_response=true` only for provider-payloa…
delete_filecan change or delete data
Delete one uploaded DeepSeek image by `file_id`. This permanently removes that provider-side file reference.
echo
get_user_balanceread-only
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.
list_conversationsread-only
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.
list_filesread-only
List images uploaded to the DeepSeek Files API. Supports cursor pagination, creation-time order, and the `user_data` purpose filter.
list_modelsread-only
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.
reset_conversationcan change or delete data
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.
retrieve_fileread-only
Retrieve metadata for one DeepSeek Files API image by `file_id`.
upload_file
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.
