What extend_package_add does on Tencent Ad MCP Server
AI agents use extend_package_add 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.
Why extend_package_add is rated Medium
This tool creates a new application extension package within the Tencent Ads system. This is a Write operation because it creates a new resource that can be modified or deleted later, with reversible effects. It is not Destructive (no deletion), Execute (no arbitrary code execution), Financial (no direct money movement), or Read (has side effects via creation).
From the tool's definition Tool name 'extend_package_add' and description '创建应用分包' (create app extension package) indicate creation of a new package resource. The 'add' operation and 'create' semantic in the description point to a Write operation that creates or modifies data.
Attacks that exploit this kind of access
The rule that runs extend_package_add safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Tencent Ad MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For extend_package_add, this is the rule to start with:
extend_package_add 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Tencent Ad MCP Server, apply this rule, and every extend_package_add call is checked against it from then on.
