AI agents call get_install_instructions to retrieve information from Codex Pets Registry without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though get_install_instructions only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

These attack patterns abuse exactly the kind of access get_install_instructions gives an agent. Each links to the full case and the policy that stops it:

Use for a known approved pet slug when the user wants CLI or manual install instructions. Do not use to search for pets or inspect general metadata; use search_pets or get_pet instead. This tool is read-only and does not increment install or download counters.. It is categorised as a Read tool in the Codex Pets Registry MCP Server, which means it retrieves data without modifying state.
Register the Codex Pets Registry MCP server in PolicyLayer and add a rule for get_install_instructions: 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 Codex Pets Registry. Nothing to install.
get_install_instructions 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 get_install_instructions 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 get_install_instructions. 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.
get_install_instructions is provided by the Codex Pets Registry MCP server (https://pets.ydb-qdrant.tech/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
