add_import · Ast Editor MCP: Risk & Policy

WHAT IT DOES

What add_import does on Ast Editor

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

WHY IT NEEDS A POLICY

Why add_import needs a policy

This tool creates or modifies code by adding import statements—a reversible change that alters source files but does not execute code or delete data. The lack of a description lowers confidence slightly, but the naming convention and server context clearly indicate a Write action.

From the tool's definition Tool name 'add_import' paired with sibling tools like 'add_field', 'add_method', 'add_parameter', 'add_top_level' that perform structural code additions.

Verdict

add_import Rate-limited

add_import stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
