code_convert · Onion MCP: Risk & Policy

WHAT IT DOES

What code_convert does on Onion

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

WHY IT NEEDS A POLICY

Why code_convert needs a policy

This tool transforms/converts code between programming languages. It creates new content (converted code) based on input, which is a Write operation. It does not execute code, delete data, or have financial implications. Severity is medium because converted code could introduce bugs or vulnerabilities if misused, but the blast radius is limited.

From the tool's definition 将代码从一种编程语言转换为另一种语言 (Convert code from one programming language to another)

code_convert Rate-limited

code_convert 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.
