guardrails_scan_secrets
AI agents call guardrails_scan_secrets to retrieve information from ThinkNEO MCP SMB without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Based on naming patterns and context of a Guardrails security module, this tool likely scans data to detect secrets without modifying it. Confidence is moderate (0.6) because the description is empty, limiting certainty about actual implementation. If the tool could remediate or redact secrets, severity would increase, but scanning alone is Read-category with low severity.
From the tool's definition Tool name 'guardrails_scan_secrets' with 'scan' prefix suggests detection/analysis of secrets; sibling tools 'guardrails_check', 'guardrails_scan_injection', 'guardrails_scan_pii' are all scanning/detection tools.

guardrails_scan_secrets. It is categorised as a Read tool in the ThinkNEO MCP SMB MCP Server, which means it retrieves data without modifying state.
Register the ThinkNEO MCP SMB MCP server in PolicyLayer and add a rule for guardrails_scan_secrets: 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 ThinkNEO MCP SMB. Nothing to install.
guardrails_scan_secrets 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 guardrails_scan_secrets 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 guardrails_scan_secrets. 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.
