importarTabla · MyPos MCP: Risk & Policy

WHAT IT DOES

What importarTabla does on MyPos MCP

AI agents use importarTabla to create or update resources in MyPos MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your MyPos MCP environment.

WHY IT NEEDS A POLICY

Why importarTabla needs a policy

'Importar' means to import data into a table, which is a Write operation (inserting/loading data). It could potentially be destructive if it overwrites existing data, but the name alone implies creation/insertion rather than deletion. Confidence is moderate because the description is uninformative ('Sigue estas reglas para importar a una tabla' provides no detail on behavior), so the exact semantics are unclear.

From the tool's definition Tool name 'importarTabla' (import to a table) combined with server context of MySQL/PostgreSQL database operations. Sibling tools include 'crearTabla', 'agregarColumna', 'consultarSQL', suggesting data manipulation capabilities.
