WHAT IT DOES

What identity_list_oauth2_providers does on Amazon Data Processing MCP Server

AI agents call identity_list_oauth2_providers to retrieve information from Amazon Data Processing MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

THE RISK

Low Risk

Why identity_list_oauth2_providers needs a policy

The 'list' verb strongly suggests a read-only operation that queries and returns a collection of OAuth2 providers. No side effects or data modification is implied. The empty description lowers confidence slightly, but the naming convention is consistent with AWS read operations. Listing identity providers is a non-destructive query operation.

From the tool's definition Tool name 'identity_list_oauth2_providers' uses the verb 'list', which indicates retrieval of data without modification.

POLICY

How to control identity_list_oauth2_providers

PolicyLayer is an MCP gateway — it sits between your AI agents and Amazon Data Processing MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for identity_list_oauth2_providers:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "identity_list_oauth2_providers": {}
  }
}

identity_list_oauth2_providers 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 Amazon Data Processing 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.
