Inspect a domain
AI agents call check_ssl to retrieve information from ToolCenter MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool performs SSL certificate inspection on a domain, which is a read-only diagnostic operation. It retrieves information about the domain's SSL/TLS certificate status, chain, and validity without making changes to any systems or data. This aligns with the 'Read' category as it queries security metadata. No code execution, data modification, deletion, or financial transaction is involved.
From the tool's definition Tool name 'check_ssl' and description 'Inspect a domain' indicate a query/inspection operation. SSL checking is a standard diagnostic read operation that retrieves certificate and security metadata without modifying any systems or data.
Attacks that exploit this kind of access
Inspect a domain. It is categorised as a Read tool in the ToolCenter MCP MCP Server, which means it retrieves data without modifying state.
Register the ToolCenter MCP server in PolicyLayer and add a rule for check_ssl: 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 ToolCenter MCP. Nothing to install.
check_ssl 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_ssl 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_ssl. 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_ssl is provided by the ToolCenter MCP server (toolcenter-dev/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
