A powerful web crawler that initiates a structured web crawl starting from a specified base URL. The crawler expands from that point like a tree, following internal links across pages. You can control how deep and wide it goes, and guide it to focus on specific sections of the site.
AI agents call tavily-crawl to retrieve information from Tavily without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool reads and retrieves web content by crawling pages, following links. It does not create, modify, delete, or execute anything — it's a read/fetch operation. Severity is medium because crawling can be broad and touch many pages, potentially triggering rate limits or accessing sensitive public content, but it causes no direct side effects.

A powerful web crawler that initiates a structured web crawl starting from a specified base URL. The crawler expands from that point like a tree, following internal links across pages. You can control how deep and wide it goes, and guide it to focus on specific sections of the site. It is categorised as a Read tool in the Tavily MCP Server, which means it retrieves data without modifying state.
Register the Tavily MCP server in PolicyLayer and add a rule for tavily-crawl: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Tavily. Nothing to install.
tavily-crawl is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the tavily-crawl rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for tavily-crawl. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
tavily-crawl is provided by the Tavily MCP server (jackedelic/tavily-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
