List SSL certificates for a domain
AI agents call list_certificates to retrieve information from Domain Suite without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves existing SSL certificate information without creating, modifying, or deleting certificates. It is a straightforward read operation analogous to 'list' or 'get' actions. The severity is low because exposing certificate metadata (existence, expiration dates) presents minimal direct risk; the information is already associated with public infrastructure.
From the tool's definition Tool name is 'list_certificates' with description 'List SSL certificates for a domain' — a retrieval operation with no side effects or data modification.
Attacks that exploit this kind of access
List SSL certificates for a domain. It is categorised as a Read tool in the Domain Suite MCP Server, which means it retrieves data without modifying state.
Register the Domain Suite MCP server in PolicyLayer and add a rule for list_certificates: 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 Domain Suite. Nothing to install.
list_certificates 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 list_certificates 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 list_certificates. 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.
list_certificates is provided by the Domain Suite MCP server (oso95/domain-suite-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
