AI agents call qf_query to retrieve information from Qingflow without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs read-only operations on Qingflow workflows. It retrieves lists, records, or summaries without modifying, deleting, or executing arbitrary operations. The sibling tools (qf_record_create, qf_record_update) clearly handle mutations, confirming this tool's read-only nature.
From the tool's definition Tool description states 'Unified read entry for list/record/summary' with 'query_mode=auto to route automatically.' The verb 'read' and absence of creation, modification, or deletion language indicate data retrieval only.
Attacks that exploit this kind of access
Unified read entry for list/record/summary. Use query_mode=auto to route automatically. It is categorised as a Read tool in the Qingflow MCP Server, which means it retrieves data without modifying state.
Register the Qingflow MCP server in PolicyLayer and add a rule for qf_query: 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 Qingflow. Nothing to install.
qf_query 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 qf_query 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 qf_query. 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.
qf_query is provided by the Qingflow MCP server (qingflow-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
