AI agents call transfer_detect-pii to retrieve information from Ruflo without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool reads content to identify personally identifiable information but does not modify, delete, or execute operations. It is a non-destructive analysis/detection function, making it a Read category tool. Severity is low because detection of PII presents minimal blast radius—the agent learns what PII exists but cannot act on that information destructively through this tool alone.
From the tool's definition Tool name 'transfer_detect-pii' with description 'Detect PII in content without redacting' indicates scanning/analysis operation. The phrase 'without redacting' clarifies it performs detection only, not modification. No side effects on data.
Attacks that exploit this kind of access
Detect PII in content without redacting Use when native package install (. It is categorised as a Read tool in the Ruflo MCP Server, which means it retrieves data without modifying state.
Register the Ruflo MCP server in PolicyLayer and add a rule for transfer_detect-pii: 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 Ruflo. Nothing to install.
transfer_detect-pii 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 transfer_detect-pii 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 transfer_detect-pii. 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.
transfer_detect-pii is provided by the Ruflo MCP server (ruvnet/ruflo). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
transfer_detect-pii is one line of Ruflo's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
