## Why oauth_refresh_token is rated Medium

Refreshing an OAuth token is a Write operation as it creates/updates a new access token (and potentially a new refresh token), modifying authentication state. It is high severity because misuse could allow an AI agent to maintain or extend unauthorized access to the Tencent Ads Marketing API, potentially enabling further manipulation of ad campaigns, financial commitments, and sensitive account data.

From the tool's own definition: "刷新 Refresh Token — this tool refreshes an OAuth refresh token, which modifies authentication credentials/session state"

## Use case

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