Returns a huge JSON object
AI agents call huge_return to retrieve information from Debug Test 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 large JSON object without creating, modifying, deleting, or executing any operations. It is a pure read operation. Severity is low because returning large data poses minimal direct risk, though in extreme cases could cause resource exhaustion (low blast radius for a typical AI misuse scenario).
From the tool's definition Tool name 'huge_return' and description 'Returns a huge JSON object' indicate retrieval of data with no modification, deletion, or side effects.
Attacks that exploit this kind of access
Returns a huge JSON object. It is categorised as a Read tool in the Debug Test MCP Server, which means it retrieves data without modifying state.
Register the Debug Test MCP server in PolicyLayer and add a rule for huge_return: 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 Debug Test. Nothing to install.
huge_return 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 huge_return 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 huge_return. 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.
huge_return is provided by the Debug Test MCP server (matsjfunke/debug-test-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
