AI agents call list_data_areas to retrieve information from AS400 MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves metadata about data areas within an AS400 library without modification, deletion, or code execution. It is purely informational with no side effects, aligning with the Read category. The 'list_' prefix and context of read-only ODBC access confirm this classification.

Register the AS400 MCP Server MCP server in PolicyLayer and add a rule for list_data_areas: 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 AS400 MCP Server. Nothing to install.
list_data_areas 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 list_data_areas 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 list_data_areas. 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.
list_data_areas is provided by the AS400 MCP Server MCP server (kozokaai/as400-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
