AI agents call security_detect_secrets to retrieve information from Musubix without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool reads and analyzes code or configuration to identify sensitive information. While the security risk of misuse is moderate (an agent could use it to find secrets to exfiltrate), the tool itself performs only detection/scanning without side effects. It is fundamentally a Read operation.
From the tool's definition The tool description explicitly states it 'detect[s]' secrets - a scanning/analysis operation with no modification capabilities. The verb 'detect' indicates retrieval and inspection of data patterns, not creation, execution, or deletion.
Attacks that exploit this kind of access
Detect hardcoded secrets like API keys, passwords, and tokens. It is categorised as a Read tool in the Musubix MCP Server, which means it retrieves data without modifying state.
Register the Musubix MCP server in PolicyLayer and add a rule for security_detect_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 Musubix. Nothing to install.
security_detect_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 security_detect_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 security_detect_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.
security_detect_secrets is provided by the Musubix MCP server (@nahisaho/musubix-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
