WHAT IT DOES

What copy_object does on Tencent Cloud COS MCP Server

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

RISK

Why copy_object is rated Medium

Copying objects in cloud storage creates or duplicates data, which is a reversible write operation. While the Chinese description '复制COS中的对象' translates directly to 'copy object in COS', this is a non-destructive modification that can be undone by deleting the copy. It does not delete, execute code, or commit financial transactions.

From the tool's definition Tool name 'copy_object' and description indicating the ability to copy objects in Tencent Cloud COS (Object Storage Service).

RECOMMENDED RULE

The rule that runs copy_object safely

copy_object Rate-limited

copy_object 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.
