AI agents call qf.query.rows 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.
The tool queries rows and returns handles/links, which is a read operation. No creation, modification, deletion, or execution semantics are described. Severity is low as it only retrieves data, though the DSL could potentially be expressive; confidence is slightly reduced because 'canonical DSL' scope is not fully specified.
From the tool's definition "Query rows" and "return query handles plus resource links" — retrieves data via a DSL with no mention of mutation
Attacks that exploit this kind of access
Query rows through the canonical DSL and return query handles plus resource links. 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.rows: 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.rows 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.rows 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.rows. 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.rows 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.
