Real-time monitoring of authentication processes
AI agents call monitor_auth_flows to retrieve information from Better Auth MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and observes real-time authentication process data for analysis and visibility purposes. It has no capability to modify authentication configurations, execute authentication flows, delete data, or trigger financial transactions.
From the tool's definition Tool name 'monitor_auth_flows' and description 'Real-time monitoring of authentication processes' indicate passive observation and querying of authentication data without modification or execution of code.
Attacks that exploit this kind of access
Real-time monitoring of authentication processes. It is categorised as a Read tool in the Better Auth MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Better Auth MCP Server MCP server in PolicyLayer and add a rule for monitor_auth_flows: 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 Better Auth MCP Server. Nothing to install.
monitor_auth_flows 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 monitor_auth_flows 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 monitor_auth_flows. 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.
monitor_auth_flows is provided by the Better Auth MCP Server MCP server (lexiconalex/better-auth-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
