AI agents use generate_leads to create or modify resources in Google Maps Mcp Server. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call generate_leads repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Google Maps Mcp Server.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Extract B2B lead lists from Google Maps by business category and geography. Returns company name, full address, contact phone, website, business category, and review metrics. Use for sales prospecting, market research, or building vendor lists. Returns 20+ leads per query by default.. It is categorised as a Write tool in the Google Maps Mcp Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Google Maps Mcp Server MCP server in PolicyLayer and add a rule for generate_leads: 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 Google Maps Mcp Server. Nothing to install.
generate_leads is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the generate_leads 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 generate_leads. 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.
generate_leads is provided by the Google Maps Mcp Server MCP server (https://nexgendata-mcp-proxy.steve-corbeil.workers.dev/google-maps-mcp-server/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
