AI agents call list_programs to retrieve information from Nuclei without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only operation that queries and returns information about programs and their associated assets. There are no side effects, data modifications, or destructive operations. It is a simple list/fetch operation typical of Read category tools.
From the tool's definition Tool name 'list_programs' and description 'List all programs and their assets currently tracked in the' indicate a retrieval/query operation that returns program and asset information without modification.
Attacks that exploit this kind of access
List all programs and their assets currently tracked in the. It is categorised as a Read tool in the Nuclei MCP Server, which means it retrieves data without modifying state.
Register the Nuclei MCP server in PolicyLayer and add a rule for list_programs: 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 Nuclei. Nothing to install.
list_programs 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 list_programs 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 list_programs. 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.
list_programs is provided by the Nuclei MCP server (tobiasguta/nuclei-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
