AI agents call get_app_release_workflow_stage 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 |
|---|---|---|---|
appName | string | Yes | Application name. Use list_applications to discover valid app names. |
organizationId | string | — | Yunxiao organization ID. When omitted, the server uses the user's default organization. |
releaseStageSn | string | Yes | Release stage serial number. Use list_app_release_stage_briefs to discover valid values. |
releaseWorkflowSn | string | Yes | Release workflow serial number. Use list_app_release_workflows to discover valid values. |
Parameters from the server's own tool schema.
The verb 'Get' combined with read-only intent (retrieve configuration details for inspection) places this in Read. No creation, modification, deletion, code execution, or financial action occurs. Low severity because disclosing deployment configuration details has limited blast radius in isolation, though could inform further attacks if combined with other tools on this DevOps platform.
From the tool's definition Tool retrieves a release workflow stage 'by serial number' with 'configuration details'—a data query operation with no side effects. Description explicitly states it gets/retrieves information about deployment phases.
Attacks that exploit this kind of access
Get an AppStack release workflow stage by serial number. Stages represent individual deployment phases with configuration details. It is categorised as a Read tool in the Yunxiao MCP Server, which means it retrieves data without modifying state.
get_app_release_workflow_stage accepts 4 parameters: appName, organizationId, releaseStageSn, releaseWorkflowSn. Required: appName, releaseStageSn, releaseWorkflowSn. 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_app_release_workflow_stage: 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_app_release_workflow_stage 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_app_release_workflow_stage 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_app_release_workflow_stage. 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_app_release_workflow_stage 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.
