dsh-search-mcp

When using DeepSeek Harness for web searches, the built-in search provider might not fully meet your customized needs for specific search engines or result quality. The dsh-search-mcp plugin is designed to solve this exact pain point by completely replacing DSH's native web search functionality with MCP (Model Context Protocol) servers. From the model's perspective, it continues to use the familiar native web_search tool, but the underlying search requests are seamlessly intercepted and routed to your configured MCP servers.

The core strength of this plugin lies in its robust compatibility and flexible configuration experience. It comes with built-in presets for major search engines like Tavily, Brave, Exa, Perplexity, and DuckDuckGo, while also supporting custom HTTP or stdio-based MCP servers. Through an intuitive visual settings interface, you can easily manage multiple server nodes, securely store API credentials, and adjust global or node-specific result limits and timeout settings. Furthermore, the plugin automatically normalizes search results and deduplicates URLs, ensuring the model receives high-quality contextual information.

If you are a DeepSeek Harness user or developer who wants to take control of search data sources, achieve higher search relevance, or build a standardized toolchain based on the MCP protocol, this plugin is the ideal choice. It not only centralizes and secures your search configurations but also significantly enhances the precision and freedom of web retrieval without requiring any changes to the model's prompting habits.
