Register the loc8n Geographic Data MCP server in PolicyLayer and add a rule for compare_demographics: 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 loc8n Geographic Data. Nothing to install.
compare_demographics 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 compare_demographics 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 compare_demographics. 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.
compare_demographics is provided by the loc8n Geographic Data MCP server (gener8v/gener8v.mcp.geographic-data). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
