AI agents call sandbox_get_pulse to retrieve information from 9192 Public Compute 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 sandbox_get_pulse 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 sandbox_get_pulse gives an agent. Each links to the full case and the policy that stops it:
Other read tools across the catalogue. The same approach applies to each: allow, with a rate cap to control cost.
Run the free sandbox quote/accept/execute/verify flow for integration testing.. It is categorised as a Read tool in the 9192 Public Compute MCP Server, which means it retrieves data without modifying state.
Register the 9192 Public Compute MCP server in PolicyLayer and add a rule for sandbox_get_pulse: 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 9192 Public Compute. Nothing to install.
sandbox_get_pulse 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 sandbox_get_pulse 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 sandbox_get_pulse. 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.
sandbox_get_pulse is provided by the 9192 Public Compute MCP server (https://nineoneninetwo.com.br/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
