AI agents call list_source_files 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 retrieves metadata about source files within a library—a read-only operation analogous to 'list' and 'get' actions. It has no side effects, does not execute code, modify data, delete resources, or move money. The limited blast radius of misuse (information disclosure of internal source code structure) warrants low severity.
From the tool's definition Tool name 'list_source_files' and description indicate retrieval of source file listings. The server description explicitly states 'read-only access to metadata, source code, and program dependencies via ODBC.' The Japanese description translates to 'Retrieve…

Register the AS400 MCP Server MCP server in PolicyLayer and add a rule for list_source_files: 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_source_files 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_source_files 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_source_files. 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_source_files 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.
