Discover URLs from a starting point. Can use both sitemap.xml and HTML link discovery.
AI agents call firecrawl_map to retrieve information from Mcp Registry Registry without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries URL information from web sitemaps and HTML pages. It performs discovery/enumeration without modifying, executing against, or deleting any data. The operations are read-only and informational in nature.
From the tool's definition Tool description states it 'Discover URLs from a starting point' using 'sitemap.xml and HTML link discovery' — purely informational operations with no side effects.

Register the Mcp Registry Registry MCP server in PolicyLayer and add a rule for firecrawl_map: 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 Mcp Registry Registry. Nothing to install.
firecrawl_map 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 firecrawl_map 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 firecrawl_map. 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.
firecrawl_map is provided by the Mcp Registry Registry MCP server (@mastra/mcp-registry-registry). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
