AI agents call get_domain_controllers 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.
This tool retrieves information about domain controllers in Active Directory. While the description is empty, the naming convention and server context strongly indicate a query operation.
From the tool's definition Tool name 'get_domain_controllers' indicates a retrieval operation. The server context describes 'exposing AD data as queryable tools'; sibling tools like 'get_blocked_inheritance_ous', 'get_computers', 'get_dc_features', and 'get_dc_file_locations' are all…
Attacks that exploit this kind of access
get_domain_controllers. 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_domain_controllers: 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_domain_controllers 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_domain_controllers 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_domain_controllers. 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_domain_controllers 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.
