xano_create_api · Xano MCP Server MCP: Risk & Policy

WHAT IT DOES

What xano_create_api does on Xano MCP Server

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

WHY IT NEEDS A POLICY

Why xano_create_api needs a policy

Creating an API in Xano would generate new endpoints or configurations that can be modified or removed later, making this a Write operation rather than Read, Execute, Destructive, or Financial. The severity is high because misconfigured APIs could expose data or create unintended data access patterns, though the action itself is reversible.

From the tool's definition Tool name 'xano_create_api' indicates creation of API resources. Context from sibling tools (xano_bulk_create_records, xano_bulk_update_records, xano_bulk_delete_records) shows this server handles reversible data modifications.
