Perform password spraying attacks across multiple targets. Supports jitter and continues on success options.
AI agents invoke cme_spray to trigger actions in CrackMapExec MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.
Password spraying is an active attack that attempts to authenticate with multiple credentials across target systems. While it could be considered Write (modifying authentication state) or Destructive (potentially locking accounts), it is most accurately Execute because: (1) it runs a coordinated attack sequence whose effects depend on argument values (target list, passwords, timing), (2) the primary effect is…
From the tool's definition Tool description states it performs 'password spraying attacks across multiple targets' with options for jitter and continuing on success.
Attacks that exploit this kind of access
Perform password spraying attacks across multiple targets. Supports jitter and continues on success options. It is categorised as a Execute tool in the CrackMapExec MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the CrackMapExec MCP Server MCP server in PolicyLayer and add a rule for cme_spray: 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_spray is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the cme_spray 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_spray. 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_spray 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.
