Register the Deadlink Checker MCP server in PolicyLayer and add a rule for check_sitemap: 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 Deadlink Checker. Nothing to install.
check_sitemap 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 check_sitemap 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 check_sitemap. 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.
check_sitemap is provided by the Deadlink Checker MCP server (yifanyifan897645/deadlink-checker-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
