CLI-first multi-source web research for AI agents and terminal users.
Connect Onesearch to Claude, Cursor or any other MCP client and it stops being a tab you switch to. CLI-first multi-source web research for AI agents and terminal users. The onesearch mcp server is what makes that connection.
onesearch 是一个 CLI-first 的研究与证据工具，面向 AI 助手、脚本和终端用户。它把综合搜索、来源发现、文档检索、网页抓取、站点结构读取、Deep Research 离线规划、配置诊断和内置 skill 分发放在同一个可复现命令层里。
The toolset is worth reading before you wire it up, because it tells you what the integration is really for:
deep — research、deep、researchInstallation goes through your MCP client rather than a global install: point it at duckduckgo-mcp-server on PyPI and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.
Configuration is passed through the environment: DEEPWIKI_API_KEY, EXA_API_KEY, OPENAI_COMPATIBLE_API_KEY. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Onesearch's toolset — deep — is a fair guide to whether it matches your workflow. It is maintained by GitHub Actions; worth a glance at recent repository activity before you build anything load-bearing on it.
