WHAT IT DOES

What inject_net_shares does on Cobalt Strike MCP Server

AI agents call inject_net_shares to retrieve information from Cobalt Strike MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why inject_net_shares is rated Low

Enumeration of network shares is a read operation that queries system information to discover available network resources. While the context (Cobalt Strike red team tool) indicates this operates in an adversarial/post-exploitation scenario where it could support further attacks, the tool itself only retrieves data.

From the tool's definition Tool name and description indicate 'Enumerate shares on a target' — a reconnaissance operation that retrieves network share information without modifying, deleting, or executing code on the target.

RECOMMENDED RULE

The rule that runs inject_net_shares 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_net_shares, this is the rule to start with:

inject_net_shares Allowed

inject_net_shares is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "inject_net_shares": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Cobalt Strike MCP Server, apply this rule, and every inject_net_shares call is checked against it from then on.
