AI agents call get_dc_software 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 strongly suggests a read operation that retrieves domain controller software inventory data. Sibling tools with identical naming conventions (get_computers, get_dc_features, get_dc_file_locations, get_dc_network_config, get_dc_services) are all queries into Active Directory metadata.
From the tool's definition Tool name 'get_dc_software' follows the 'get_' prefix pattern consistent with sibling tools (get_computers, get_blocked_inheritance_ous, get_certification_authorities, etc.) which are all read operations.
Attacks that exploit this kind of access
get_dc_software. 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_software: 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_software 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_software 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_software. 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_software 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.
