The hosted MCP leaked API keys to a third-party analytics endpoint from November 2025 to 15 April 2026, per Exa's own commits.\n\n**SearchAPI.io.** 99.9% SLA on every plan and no incidents on the status page since August. MCP exposes over 100 tools with no toolsets.\n\n## Before you call either\n\n### Exa API + MCP\n\n1. Send the key as `x-api-key` or a Bearer header, never `?exaApiKey=` in the MCP URL\n2. Ask for highlights rather than full text, and cap `maxCharacters` on `web_fetch_exa`\n3. Request only the results you'll read. More than 10 costs extra, and x402 calls stop at 10\n4. On 429, honour `Retry-After`. The QPS limit is shared by every key on the team\n5. Add `?tools=web_search_advanced_exa` for domain and date filters instead of packing them into the query\n\n### SearchAPI.io\n\n1. Send the key as `Authorization: Bearer`, not `api_key=` in the URL\n2. Connect the MCP through OAuth or the `X-MCP-Token` header, not the registry's `?token=` URL\n3. Call the REST API with `engine=` when context is tight. The MCP loads over 100 tool definitions\n4. Page Google results with `page`. `num` is fixed at 10\n5. Pace bursts. One hour can use at most 20 per cent of the plan's monthly searches\n\n## Other comparisons with Exa API + MCP or SearchAPI.io\n\n- [Brave Search API + MCP vs Exa API + MCP](https://www.anchorterminal.com/compare/brave-search-mcp-vs-exa-mcp.md)\n- [Brave Search API + MCP vs SearchAPI.io](https://www.anchorterminal.com/compare/brave-search-mcp-vs-searchapi-io.md)\n- [Exa API + MCP vs Firecrawl MCP](https://www.anchorterminal.com/compare/exa-mcp-vs-firecrawl-mcp.md)\n- [Exa API + MCP vs Linkup](https://www.anchorterminal.com/compare/exa-mcp-vs-linkup.md)\n- [Exa API + MCP vs Parallel Search and Task APIs](https://www.anchorterminal.com/compare/exa-mcp-vs-parallel-search-api.md)\n- [Exa API + MCP vs SerpApi](https://www.anchorterminal.com/compare/exa-mcp-vs-serpapi.md)\n- [Exa API + MCP vs Serper](https://www.anchorterminal.com/compare/exa-mcp-vs-serper.md)\n- [Exa API + MCP vs Tavily API + MCP](https://www.anchorterminal.com/compare/exa-mcp-vs-tavily-mcp.md)\n- [Exa API + MCP vs Valyu](https://www.anchorterminal.com/compare/exa-mcp-vs-valyu.md)\n- [Exa API + MCP vs You.com APIs](https://www.anchorterminal.com/compare/exa-mcp-vs-you-com-api.md)\n- [Firecrawl MCP vs SearchAPI.io](https://www.anchorterminal.com/compare/firecrawl-mcp-vs-searchapi-io.md)\n- [Linkup vs SearchAPI.io](https://www.anchorterminal.com/compare/linkup-vs-searchapi-io.md)\n- [Parallel Search and Task APIs vs SearchAPI.io](https://www.anchorterminal.com/compare/parallel-search-api-vs-searchapi-io.md)\n- [SearchAPI.io vs SerpApi](https://www.anchorterminal.com/compare/searchapi-io-vs-serpapi.md)\n- [SearchAPI.io vs Serper](https://www.anchorterminal.com/compare/searchapi-io-vs-serper.md)\n- [SearchAPI.io vs Tavily API + MCP](https://www.anchorterminal.com/compare/searchapi-io-vs-tavily-mcp.md)\n- [SearchAPI.io vs Valyu](https://www.anchorterminal.com/compare/searchapi-io-vs-valyu.md)\n- [SearchAPI.io vs You.com APIs](https://www.anchorterminal.com/compare/searchapi-io-vs-you-com-api.md)\n- [Exa API + MCP vs Fetch (MCP reference server)](https://www.anchorterminal.com/compare/exa-mcp-vs-fetch-reference-server.md)\n",
