Query registry value
AI agents call execute_reg_queryv to retrieve information from Cobalt Strike MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool reads registry values from a target system, which is a read operation. However, in the context of a Cobalt Strike red team framework operating on compromised beacons, even read operations carry high severity — registry queries can expose credentials, configuration secrets, installed software, and security tool presence on victim systems. The blast radius of misuse is high given the offensive tooling context.
From the tool's definition 'Query registry value' indicates a read operation on the Windows registry

Query registry value. It is categorised as a Read tool in the Cobalt Strike MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Cobalt Strike MCP Server MCP server in PolicyLayer and add a rule for execute_reg_queryv: 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.
execute_reg_queryv 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 execute_reg_queryv 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 execute_reg_queryv. 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.
execute_reg_queryv 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.
