WHAT IT DOES

What oauth_refresh_token does on Tencent Ad MCP Server

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.

RISK

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 definition 刷新 Refresh Token — this tool refreshes an OAuth refresh token, which modifies authentication credentials/session state

oauth_refresh_token Rate-limited

oauth_refresh_token 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.
