serpdive/serpdive-mcp

Give any MCP client real-time web search with answer-ready results. SERPdive is the AI Search API: ask a question, get the actual content of the best pages, extracted, cleaned, and sized for an LLM. On a public, replayable 1,000-question benchmark, SERPdive runs at the same speed as Tavily, feeds your LLM 20.2% fewer tokens, and wins 60.7% of decided quality duels. If you are evaluating Tavily alternatives, that benchmark is public and replayable end to end: same questions, same judge, your machine.
**There is a free tier, and it has no ceiling.** The krill model is free and unlimited under fair use — no card, no credits, nothing to decrement. It returns the shortest set of sentences that still answers (about 700 tokens a search, roughly half what the usual alternatives send), one request at a time, at low priority. Use it to build; switch one word to mako when you need depth and steady latency.
One tool, serpdive_search. Two ways to run it:
- **Hosted (recommended)**: https://mcp.serpdive.com, nothing to install.
- **Local (this package)**: npx -y serpdive-mcp, stdio, zero dependencies.

The tool
serpdive_search(query, model?, max_results?)
| Argument | Type | Description |
|---|---|---|
| query | string, required | The search, in any language. Localization is automatic. |
| model | "mako" \| "moby" | mako (default): the fact-carrying sentences of each page, fast. moby: full page text — slower (~1s more) and several times more tokens; use only when mako's key sentences are insufficient (long-document analysis, deep research). |
| max_results | integer, 1-10 | Cap on delivered results. Omit for the engine's calibrated mix. |
The response is the raw SERPdive JSON: query, model, response_time_ms, optional extra_info, and results as [{ url, title, date?, content }]. Failed searches are never billed.
