AI agents call cat_say to retrieve information from SSMCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and returns a cat image with custom text overlay. There are no modifications to data, no code execution, no destructive operations, and no financial implications. It is a simple read-only operation that queries an external service or resource and returns the result to the user.
From the tool's definition Tool name 'cat_say' and description 'Get a cat image with custom text' indicate data retrieval with no side effects. The verb 'Get' explicitly denotes a read operation.
Attacks that exploit this kind of access
Get a cat image with custom text. It is categorised as a Read tool in the SSMCP MCP Server, which means it retrieves data without modifying state.
Register the SS MCP server in PolicyLayer and add a rule for cat_say: 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 SSMCP. Nothing to install.
cat_say 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 cat_say 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 cat_say. 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.
cat_say is provided by the SS MCP server (olahol/ssmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
