AI agents use ssl_renew to create or modify resources in BorealHost. 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 ssl_renew 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 BorealHost.

Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Every attack above starts with a tool call. PolicyLayer checks each one against your policy first, so ssl_renew only ever does what you allow.

What does the ssl_renew tool do? +

Force SSL certificate renewal via certbot. Requires: API key with write scope. Args: slug: Site identifier Returns: {"renewed": true, "expires_at": "iso8601"}. It is categorised as a Write tool in the BorealHost MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on ssl_renew? +

Register the BorealHost MCP server in PolicyLayer and add a rule for ssl_renew: 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 BorealHost. Nothing to install.

What risk level is ssl_renew? +

ssl_renew is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit ssl_renew? +

Yes. Add a rate_limit block to the ssl_renew 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.

How do I block ssl_renew completely? +

Set action: deny in the PolicyLayer policy for ssl_renew. 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.

What MCP server provides ssl_renew? +

ssl_renew is provided by the BorealHost MCP server (pypi:borealhost-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every BorealHost tool call.
