AI agents use unassign_proxy_from_account to create or update resources in Telegram MCP Complete — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Telegram MCP Complete environment.
This tool modifies account proxy settings by removing an assignment. It is reversible (a new proxy can be reassigned), so it falls under Write rather than Destructive. The severity is medium because misuse could redirect an account's traffic, potentially for surveillance or man-in-the-middle attacks, but the action is not irreversible and does not directly move money or execute arbitrary code.
From the tool's definition Tool name 'unassign_proxy_from_account' and description '取消账号的独立代理分配' (cancel/remove independent proxy assignment from account) indicates modification of account configuration settings. This reverses a prior proxy assignment without deleting data.

"window": "minute",
"max": 30,
"scope": "grant"
}
]
