List all loaded modules/DLLs
AI agents call list_modules to retrieve information from MCP Debug Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information about loaded modules and DLLs in a debugged process. It performs a read-only query that returns data without modifying system state, executing code, or triggering external operations. While the server context involves debugging (a powerful capability), this specific tool is purely informational.
From the tool's definition Tool name 'list_modules' and description 'List all loaded modules/DLLs' indicate a querying/inspection operation with no side effects.
Attacks that exploit this kind of access
List all loaded modules/DLLs. It is categorised as a Read tool in the MCP Debug Server MCP Server, which means it retrieves data without modifying state.
Register the MCP Debug Server MCP server in PolicyLayer and add a rule for list_modules: 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 MCP Debug Server. Nothing to install.
list_modules 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_modules 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_modules. 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_modules is provided by the MCP Debug Server MCP server (nickzer0/mcp-debugserver). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
