AI agents call get_forest_info 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 queries forest-level information from Active Directory without creating, modifying, deleting, or executing operations. It is purely informational and has no side effects on the system. The scope is read-only access to forest configuration metadata, which presents minimal risk even if accessed by an unauthorized agent.
From the tool's definition Tool name 'get_forest_info' and description 'Return forest-level information' indicate data retrieval with no modification. Returns metadata (name, functional level, schema version) about the Active Directory forest.
Attacks that exploit this kind of access

Register the Legacy MCP server in PolicyLayer and add a rule for get_forest_info: 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_forest_info 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_forest_info 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_forest_info. 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_forest_info 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.
