AI agents call list_programs 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 performs a query/list operation to retrieve metadata about programs from an AS400/IBM i system. It has no side effects—it only retrieves and displays information. This aligns with the Read category pattern (list, get, fetch). The server is documented as read-only, and this tool fits the retrieval use case without modification, deletion, or execution of arbitrary code.
From the tool's definition Tool name 'list_programs' and description indicating retrieval of program list within a library ('ライブラリ内のプログラム一覧を取得します' = 'Get a list of programs in a library').

Register the AS400 MCP Server MCP server in PolicyLayer and add a rule for list_programs: 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_programs 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_programs 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_programs. 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_programs 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.
