List available modules for a protocol or get options for a specific module.
AI agents call cme_modules to retrieve information from CrackMapExec MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only retrieves metadata about available CrackMapExec modules and their configuration options. It performs no side effects, executes no commands, modifies no data, and poses no direct security risk. The blast radius of misuse is minimal—an attacker gains only information about what capabilities exist, not the ability to exercise those capabilities.
From the tool's definition Tool description states it 'List[s] available modules for a protocol or get options for a specific module' — purely informational retrieval with no modification, execution, or destructive capability.
Attacks that exploit this kind of access
List available modules for a protocol or get options for a specific module. It is categorised as a Read tool in the CrackMapExec MCP Server MCP Server, which means it retrieves data without modifying state.
Register the CrackMapExec MCP Server MCP server in PolicyLayer and add a rule for cme_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 CrackMapExec MCP Server. Nothing to install.
cme_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 cme_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 cme_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.
cme_modules is provided by the CrackMapExec MCP Server MCP server (schwarztim/sec-crackmapexec-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
