What inject_postExDll does on Cobalt Strike MCP Server
AI agents invoke inject_postExDll to trigger actions in Cobalt Strike 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.
Why inject_postExDll is rated High
This tool loads a post-exploitation DLL into a beacon/process context within a Cobalt Strike red team framework. Loading arbitrary DLLs executes code in the target environment, enabling privilege escalation, lateral movement, credential theft, or full system compromise. This is an Execute-category action with critical severity due to the unrestricted code execution capability in an offensive security context.

The rule that runs inject_postExDll safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Cobalt Strike MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For inject_postExDll, this is the rule to start with:
inject_postExDll stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Cobalt Strike MCP Server, apply this rule, and every inject_postExDll call is checked against it from then on.
Questions about inject_postExDll
Load post-exploitation DLL. It is categorised as a Execute tool in the Cobalt Strike MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Cobalt Strike MCP Server MCP server in PolicyLayer and add a rule for inject_postExDll: 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 Cobalt Strike MCP Server. Nothing to install.
inject_postExDll 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 inject_postExDll 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 inject_postExDll. 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.
inject_postExDll is provided by the Cobalt Strike MCP Server MCP server (mickeydb/cobalt-strike-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
