Sifthound is an MIT-licensed, self-hosted web search / extract / crawl / map API for AI agents, exposing a Tavily-compatible interface plus an MCP server. It is brand-new and unproven — created 2026-09-23, last pushed 2026-09-25, 0 stars — so treat it as a fresh drop, not an adopted tool. The value is that it is self-hostable: an owned endpoint you run rather than a paid search API you call.
Agent enrichment and research flows lean on a search/extract API — usually a paid, hosted one billed per call. Sifthound's angle is to be that same shape of API, Tavily-compatible, but self-hosted: you run the endpoint, own the traffic, and swap it in wherever your agents already call a Tavily-style interface, with an MCP server on top. For a team doing agent-driven enrichment at volume, moving that layer in-house changes both the cost curve and the data-control story. The honest read: at 0 stars and two days old, this is a fresh drop with no adoption behind it — attractive as an owned alternative in principle, but the compatibility and extraction quality are unproven, so pilot it against your real workload before you build on it.
