Why reset_oauth_client_secret needs a policy

Resetting an OAuth client secret modifies a security credential, invalidating the old secret and generating a new one. This is a Write operation (creates new secret value) rather than Destructive since the client itself isn't deleted. However, severity is high because misuse could break all applications using the old secret or allow an attacker to take over OAuth flows.

POLICY

How to control reset_oauth_client_secret

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "reset_oauth_client_secret": {
      "limits": [
        {
          "counter": "reset_oauth_client_secret_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

reset_oauth_client_secret stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Questions about reset_oauth_client_secret

What does the reset_oauth_client_secret tool do? +

Reset an OAuth client secret. It is categorised as a Write tool in the Linode MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on reset_oauth_client_secret? +

Register the Linode MCP Server MCP server in PolicyLayer and add a rule for reset_oauth_client_secret: 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 Linode MCP Server. Nothing to install.

What risk level is reset_oauth_client_secret? +

reset_oauth_client_secret is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit reset_oauth_client_secret? +

Yes. Add a rate_limit block to the reset_oauth_client_secret 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 reset_oauth_client_secret completely? +

Set action: deny in the PolicyLayer policy for reset_oauth_client_secret. 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 reset_oauth_client_secret? +

reset_oauth_client_secret is provided by the Linode MCP Server MCP server (takashito/linode-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 Linode MCP Server tool call.

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