将 Spec 内容同步到目标文件。deterministic 模式直接写入，agent 模式通过 AI 分析差异。
AI agents use qflow_spec_sync 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 creates or modifies file content by syncing specification data to target files. While it performs writes, it is reversible (files can be edited or reverted), so it is categorized as Write rather than Destructive.
From the tool's definition Tool description states '将 Spec 内容同步到目标文件' (sync Spec content to target file) with two modes: 'deterministic 模式直接写入' (deterministic mode writes directly) and 'agent 模式通过 AI 分析差异' (agent mode analyzes differences via AI).
Documented attack patterns abuse exactly the kind of access qflow_spec_sync 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_spec_sync:
{
"version": "1",
"default": "deny",
"tools": {
"qflow_spec_sync": {
"limits": [
{
"counter": "qflow_spec_sync_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}qflow_spec_sync 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.

Register the Qflow MCP server in PolicyLayer and add a rule for qflow_spec_sync: 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_spec_sync 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_spec_sync 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_spec_sync. 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_spec_sync 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.
