get_data
AI agents call get_data 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.
Given the server's stated read-only mandate and the consistent naming pattern of sibling tools that retrieve information, 'get_data' almost certainly retrieves or queries data without side effects. This matches the Read category. Severity is low because data retrieval poses minimal risk unless the data itself is sensitive (which is not indicated here), and the server enforces read-only constraints.
From the tool's definition The tool is named 'get_data' and resides on a server explicitly described as providing 'read-only access to metadata, source code, and program dependencies.' The sibling tools (get_columns, get_source, get_table_info, get_system_info, list_*) all follow a…
Attacks that exploit this kind of access
get_data. 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_data: 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_data 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_data 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_data. 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_data 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.
