AI agents call exportarTabla to retrieve information from MyPos MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool exports table data, which is a read-only operation that retrieves information from the database and outputs it without creating, modifying, or deleting any data. While the description provided is minimal, the naming convention and server context (focused on listing tables and executing SELECT queries) strongly suggest this is a data retrieval function rather than a write, destructive, or execute operation.
From the tool's definition Tool name 'exportarTabla' indicates data export/retrieval operation. Server description emphasizes SELECT queries and data retrieval capabilities. Export operations retrieve and output data without modifying the source.

exportarTabla 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 exportarTabla 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 exportarTabla. 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.
