AI agents call deactivate_license to retrieve information from Creem without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Even though deactivate_license only reads data, uncontrolled read access leaks sensitive information and racks up API costs — an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Attacks that exploit this kind of access
Deactivate a license key instance. It is categorised as a Read tool in the Creem MCP Server, which means it retrieves data without modifying state.
Register the Creem MCP server in PolicyLayer and add a rule for deactivate_license: 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 Creem. Nothing to install.
deactivate_license 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 deactivate_license 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 deactivate_license. 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.
deactivate_license is provided by the Creem MCP server (selenium39/mcp-server-creem). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
