What spawn_net_share does on Cobalt Strike MCP Server
AI agents invoke spawn_net_share 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 spawn_net_share is rated High
While the primary function is enumeration (Read), 'spawn mode' means it actively spawns a new beacon or process on a target system to perform the operation. Spawning processes on compromised hosts is an Execute-level action with significant blast radius in a red team/adversarial context. The Cobalt Strike context elevates severity considerably as this is offensive security tooling with live targets.
From the tool's definition 'spawn mode' indicates the tool spawns a process/beacon to enumerate shares, rather than passively querying; operates within Cobalt Strike red team C2 infrastructure
Attacks that exploit this kind of access
The rule that runs spawn_net_share 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 spawn_net_share, this is the rule to start with:
spawn_net_share 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 spawn_net_share call is checked against it from then on.
Questions about spawn_net_share
Enumerate shares (spawn mode). 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 spawn_net_share: 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.
spawn_net_share 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 spawn_net_share 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 spawn_net_share. 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.
spawn_net_share 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.
