AI agents call get_source 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 source code from AS400/IBM i systems without executing it or modifying data. It is a read-only operation consistent with the server's read-only access model for development support. No side effects, code execution, or data modification occurs. Typical blast radius is very low—exposure of source code is a confidentiality concern but not reversible damage.
From the tool's definition Tool name is 'get_source' which retrieves source code. Server description explicitly states 'read-only access to metadata, source code, and program dependencies via ODBC'.
Attacks that exploit this kind of access
ソースコードを取得します。. It is categorised as a Read tool in the AS400 MCP Server MCP Server, which means it retrieves data without modifying state.
Register the AS400 MCP Server MCP server in PolicyLayer and add a rule for get_source: 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.
get_source 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_source 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_source. 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_source 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.
