Switch from Tavily MCP to Scavio MCP to stop hitting rate limits: 50 free credits on signup, no per-minute throttle, 50 platforms from one config block. Tavily's free tier MCP server hits rate limits after roughly 20 minutes of active agent use, blocking search calls until the window resets. Brave dropped its free tier entirely. SearXNG is free but gets blocked by Google after sustained use.
Why Tavily rate limits hit fast
Tavily's free tier has a per-minute rate limit, not just a monthly cap. An agent making 3-5 searches per task burns through the minute limit in under 20 minutes of continuous use. After the Nebius acquisition ($275M), Tavily shifted toward enterprise pricing, making the free tier more restrictive.
Alternative 1: Scavio MCP
50 free credits on signup with no per-minute throttle. Multi-platform search (Google, YouTube, Amazon, Walmart, Reddit, TikTok). Setup takes one config block.

}Alternative 2: Brave Search API
No free tier as of 2026 (removed). Starts at $5 prepaid/month, roughly $4-5 per 1,000 queries. Good for Google-equivalent web search but limited to one platform.
Alternative 3: Self-hosted SearXNG
Free and private, but requires Docker hosting and maintenance. Gets blocked by Google after heavy use. Good for hobby projects, unreliable for production agents.

Provider | Free tier | Rate limit | Paid
Tavily | 1K/mo | ~20 min wall | Enterprise focus
Scavio | 50 on signup | No per-min limit | $30/mo = 7K credits
Brave | None (removed)| Moderate | $5 prepaid/mo
SearXNG | Unlimited | Gets blocked | Self-host cost
Exa | 1K/mo | Moderate | $7/1K searchesRecommendation
For agents making fewer than 50 credits on signupnth: Scavio free tier. For 250-1,000/month: Exa or Tavily free tier (if you can tolerate the rate limit). Above 1,000/month: Scavio at $30/month for 7K credits covers most production agent workloads.
