Lista las categorías de gasto del usuario. Por defecto devuelve jerarquía; usa plano=true para lista plana. Args: - plano (boolean, opcional): true para lista plana sin jerarquía (defecto false).

Part of the Gastos Flow MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

AI agents call gastos_flow_list_categorias to retrieve information from Gastos Flow without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.

Even though gastos_flow_list_categorias only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.

Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.
