Why analyze_current_auth needs a policy

This tool queries and examines existing authentication configurations without creating, modifying, executing, deleting, or moving any data or resources. It performs analysis similar to audit or discovery operations, which are inherently read-only operations with no side effects.

From the tool's definition Tool name 'analyze_current_auth' and description 'Detect and analyze existing auth.js/next-auth implementation' indicate a read-only inspection operation.

POLICY

How to control analyze_current_auth

PolicyLayer is an MCP gateway — it sits between your AI agents and Better Auth MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for analyze_current_auth:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "analyze_current_auth": {}
  }
}

analyze_current_auth is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Better Auth MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

How do I enforce a policy on analyze_current_auth? +

Register the Better Auth MCP Server MCP server in PolicyLayer and add a rule for analyze_current_auth: 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.

What risk level is analyze_current_auth? +

Can I rate-limit analyze_current_auth? +

Yes. Add a rate_limit block to the analyze_current_auth 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.

How do I block analyze_current_auth completely? +

Set action: deny in the PolicyLayer policy for analyze_current_auth. 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.

What MCP server provides analyze_current_auth? +

analyze_current_auth is provided by the Better Auth MCP Server MCP server (jamesjohnsdev/better-auth-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Better Auth MCP Server tool call.

Start from Better Auth MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
