AI agents call get_dc_network_config to retrieve information from LegacyMCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The 'get_' prefix and alignment with other query-only sibling tools indicate this retrieves Domain Controller network configuration data without modification. The empty description reduces confidence slightly, but the naming convention strongly suggests a Read operation (queries AD data with no side effects).
From the tool's definition Tool name 'get_dc_network_config' uses the 'get_' prefix, consistent with sibling tools like 'get_blocked_inheritance_ous', 'get_certification_authorities', 'get_computer_summary', 'get_computers', 'get_dc_features', 'get_dc_file_locations',…
Attacks that exploit this kind of access
get_dc_network_config. It is categorised as a Read tool in the LegacyMCP MCP Server, which means it retrieves data without modifying state.
Register the Legacy MCP server in PolicyLayer and add a rule for get_dc_network_config: 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 LegacyMCP. Nothing to install.
get_dc_network_config 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 get_dc_network_config 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 get_dc_network_config. 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.
get_dc_network_config is provided by the Legacy MCP server (marco-lelli/legacy-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
