AI agents call get_network to retrieve information from Defined without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves network information by ID, which is a pure read operation. It does not create, modify, delete, or execute any actions—it simply queries and returns data. There is no capability for unintended consequences or blast radius beyond information disclosure, making severity low.
From the tool's definition Tool name 'get_network' and description 'Get a network by ID' indicate a retrieval operation with no modification or execution of side effects.
Attacks that exploit this kind of access
Get a network by ID. It is categorised as a Read tool in the Defined MCP Server, which means it retrieves data without modifying state.
Register the Defined MCP server in PolicyLayer and add a rule for get_network: 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 Defined. Nothing to install.
get_network 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_network 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_network. 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_network is provided by the Defined MCP server (quickvm/defined-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
