Get a comprehensive overview of an Appstack system including basic info, attached applications, and members in one read-only call. Use this after discovering a system via list_systems.
AI agents call get_system_overview to retrieve information from Yunxiao without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
appLimit | number | — | Max attached applications returned. Defaults to 10. |

Parameters from the server's own tool schema.
This tool purely retrieves and queries system metadata with no side effects. The 'read-only' designation confirms it performs information retrieval only. The blast radius is minimal—an agent misusing this tool would at worst gain visibility into system structure and membership, posing only an information disclosure risk, not operational or financial impact.
From the tool's definition Tool is explicitly described as 'read-only call' that retrieves 'comprehensive overview' of system information including 'basic info, attached applications, and members'. No modification, deletion, or execution capabilities.
Attacks that exploit this kind of access
Get a comprehensive overview of an Appstack system including basic info, attached applications, and members in one read-only call. Use this after discovering a system via list_systems. It is categorised as a Read tool in the Yunxiao MCP Server, which means it retrieves data without modifying state.
get_system_overview accepts 6 parameters: appLimit, systemName, includeApps, memberLimit, includeMembers, organizationId. Required: systemName. The full parameter table on this page comes from the server's own tool schema.
Register the Yunxiao MCP server in PolicyLayer and add a rule for get_system_overview: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Yunxiao. Nothing to install.
get_system_overview is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_system_overview rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for get_system_overview. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
get_system_overview is provided by the Yunxiao MCP server (@futuretea/yunxiao-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
