What wps_cache_data does on Wps Office
AI agents call wps_cache_data to retrieve information from Wps Office without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
key | string | Yes | 缓存键名，用于后续获取数据 |
data | object | Yes | 要缓存的数据（任意JSON对象） |
appType | string | — | 数据来源应用类型：et（表格）、wps（文字）、wpp（演示） |
Parameters from the server's own tool schema.
Why wps_cache_data is rated Low
Even though wps_cache_data only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Attacks that exploit this kind of access
The rule that runs wps_cache_data safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Wps Office, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For wps_cache_data, this is the rule to start with:
wps_cache_data is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Wps Office, apply this rule, and every wps_cache_data call is checked against it from then on.
