Jev Search MCP

Jev Search packaged for agents in three forms: a Claude Code plugin that answers the built-in WebSearch with Jev, an npm MCP server, and a CLI. It is a zero-runtime-dependency JavaScript package, and when installed as a plugin the built-in WebSearch takes over only when Jev cannot answer.

WebSearch calls are answered by Jev: the response keeps the built-in format plus a line saying Answered by Jev Search and a ranked list with relevance percentages. If Jev errors, is rate-limited, has no network, or domain filtering removes every result, it silently falls back to the built-in search with a dim one-line note.

Claude Code 2.1.271+ with function hooks enabled, e.g. CLAUDE_CODE_ENABLE_FUNCTION_HOOKS=1 in ~/.claude/settings.json, then `claude plugin marketplace add mukiwu/muki-ai-plugins` and `claude plugin install jev-search@muki-ai-plugins`. Installation asks for the Jev Search instance URL, whether to intercept WebSearch, and results per query; defaults point at jev.s1.dev.

Run `npx -y jev-search-mcp` as a stdio MCP server, for example `codex mcp add jev-search -- npx -y jev-search-mcp`, with JEV_SEARCH_BASE_URL set when not using the default instance. Node 22 is required, and this path does not intercept the built-in web search.

Requests go to POST /api/ask (same-origin Origin header, over 300 characters truncated at a word boundary) and stream back NDJSON events. Results are deduplicated by URL, merging engines that hit the same link; ordering is Jev's relevance percentage first, then how many engines matched, then original rank, with unscored results last.

Google, DuckDuckGo and Yandex through Search1API, plus Hacker News, Reddit, GitHub, X, arXiv, YouTube, Wikipedia, IMDb and WeChat when needed. Jev picks the sources, time window and keywords from your plain-language sentence.

No — Jev decides and ranks; it does not fetch page content, so the README's agent instructions tell the model to fetch and read the links it receives. There is also a skill-only install path via `npx skills add mukiwu/jev-search-mcp` that uses the CLI from the shell instead of MCP.
