SERPdive MCP Server

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.

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.

Get a free API key at serpdive.com/dashboard/keys (no card required).

Hosted server

Claude Code

claude mcp add --transport http serpdive https://mcp.serpdive.com \
  --header "Authorization: Bearer sd_live_YOUR_KEY"

Cursor and other JSON-config clients

{
  "mcpServers": {
    "serpdive": {
      "url": "https://mcp.serpdive.com/?key=sd_live_YOUR_KEY"
    }
  }
}

Both https://mcp.serpdive.com/ and https://mcp.serpdive.com/mcp answer, so either URL shape works.

The tool

serpdive_search(query, model?, max_results?)

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.

There is no answer argument here, on purpose. Over MCP the consumer is always an LLM, which can write its own answer from the extracted content — a second, server-side synthesis costs a round-trip on every search and buys nothing. The API still offers answer: true for callers that are not models.

Pricing and limits

A mako search costs 1 credit, moby 1.5. Every account gets free monthly credits, no card required. Full reference: serpdive.com/docs.
