AI agents use qflow_task_batch to create or update resources in Qflow — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Qflow environment.
This tool primarily performs reversible write operations (create, update, rewrite) on tasks in bulk. While it includes a query component ('查询状态'/query status), the write operations (create/update/rewrite) are the dominant functionality. These are reversible changes that don't permanently destroy data, placing it in the Write category rather than Destructive or Execute.
From the tool's definition Tool description states '批量任务操作：创建/更新/查询状态/重写' (batch task operations: create/update/query status/rewrite). The presence of '创建' (create) and '更新' (update) indicates data modification capabilities. '重写' (rewrite) suggests overwriting existing data.
Documented attack patterns abuse exactly the kind of access qflow_task_batch gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Qflow, and nothing reaches the server without passing your rules. This is the rule we recommend for qflow_task_batch:
{
"version": "1",
"default": "deny",
"tools": {
"qflow_task_batch": {
"limits": [
{
"counter": "qflow_task_batch_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}qflow_task_batch 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.

批量任务操作：创建/更新/查询状态/重写. It is categorised as a Write tool in the Qflow MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Qflow MCP server in PolicyLayer and add a rule for qflow_task_batch: 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 Qflow. Nothing to install.
qflow_task_batch is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the qflow_task_batch 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 qflow_task_batch. 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.
qflow_task_batch is provided by the Qflow MCP server (pangu-immortal/qflow). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Qflow, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
