Deepseek Thinker MCP Server is a Model Context Protocol provider that surfaces Deepseek's internal reasoning to MCP-enabled AI clients, such as Claude Desktop. It supports dual operation modes: OpenAI API mode, using API_KEY and BASE_URL for remote access to Deepseek's reasoning, and Ollama local mode, enabled by USE_OLLAMA=true for local hosting. The server exposes the get-deepseek-thinker MCP tool, which takes an originPrompt and returns a structured text response containing the reasoning process. It can be consumed either through the Deepseek API service or a local Ollama instance, enabling flexible deployment. Integration with AI clients like Claude Desktop is facilitated by a claude_desktop_config.json snippet, and a local server can be started via Node or by building the project and running node build/index.js. The project uses TypeScript, the @modelcontextprotocol/sdk, OpenAI API, Ollama, and Zod for parameter validation, and follows an npm-based development workflow (install, build, run).
