consultarSQL · MyPos MCP: Risk & Policy

WHAT IT DOES

What consultarSQL does on MyPos MCP

AI agents invoke consultarSQL to trigger actions in MyPos MCP. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why consultarSQL needs a policy

The server description mentions executing SELECT queries, suggesting this tool runs SQL queries. However, with sibling tools like 'crudTabla' (CRUD operations), 'crearTabla' (create table), 'eliminarColumna' (delete column), it's plausible this tool could execute arbitrary SQL beyond just SELECT. The empty description lowers confidence.

From the tool's definition Tool name 'consultarSQL' (query with SQL) on a server described as 'allowing users to execute SELECT queries' — but the description body is empty/uninformative beyond the name itself.
