AI agents call get_privileged_accounts 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 and lists privileged account information from AD. While the data it exposes is sensitive (privileged accounts), the operation itself is non-destructive read-only access. It performs a query similar to other sibling tools (get_computers, get_certification_authorities, etc.) that are clearly Read operations.
From the tool's definition Tool name 'get_privileged_accounts' and description 'Return accounts that are members of privileged groups' indicates a query/retrieval operation that surfaces existing data from Active Directory without modification or deletion.

Attacks that exploit this kind of access
Return accounts that are members of privileged groups. 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_privileged_accounts: 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_privileged_accounts 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_privileged_accounts 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_privileged_accounts. 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_privileged_accounts 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.
