WHAT IT DOES

What kinsta.sftp-users.add does on Kinsta MCP Server

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

WHY IT NEEDS A POLICY

Why kinsta.sftp-users.add needs a policy

Creating an SFTP/SSH user account is a reversible write operation that adds a new credential and access mechanism to the hosting environment. While this could enable unauthorized access if misused by an AI agent, the operation itself is not destructive (accounts can be deleted), not financial, and does not directly execute arbitrary code. It modifies infrastructure configuration, placing it in the Write category.

From the tool's definition Tool description states 'Add a new additional SFTP/SSH user account to an environment' — the verb 'Add' and 'new' indicate creation of a new account resource, which is a write operation that modifies infrastructure state.
