The Tavily MCP Server brings production-ready, real-time web intelligence to AI agents running inside Caylex projects. It equips agents with the ability to perform live web searches, extract structured content from specific URLs, crawl entire websites, and map site structures — making it ideal for use cases such as live research, competitive analysis, content monitoring, and intelligent data retrieval. Tavily is purpose-built for AI agents rather than general-purpose browsing, meaning its results are optimized for relevance, freshness, and AI consumption. By adding this server to a Caylex project, agents gain a comprehensive suite of web-access tools that span from broad topic searches down to deep, targeted page extraction and crawling.
Prerequisites:
  • A Tavily account with an active API key is required; sign up at app.tavily.com.
  • Sufficient Tavily API credits on your account are needed before invoking search, extract, crawl, or map tools.
Important API details:
  • A valid Tavily API key is required to authenticate all tool calls; the key must be provided as a header when configuring the server in Caylex.
  • Tavily API usage is metered against your Tavily account’s credit quota — high-frequency crawling or extraction tasks may consume credits quickly.
  • The tavily_crawl and tavily_map tools operate on entire site structures and may be subject to depth and page-count limits depending on your Tavily plan.
  • tavily_skill provides pre-built agent skill workflows (e.g., research pipelines) that internally compose multiple Tavily operations in a single call.
