Why identity_update_oauth2_provider needs a policy

The word 'update' in the tool name implies a Write operation that modifies an existing OAuth2 provider's identity configuration. This could affect authentication/authorization for services, making misuse potentially high severity. However, the empty description significantly lowers confidence in this classification.

From the tool's definition Tool name: identity_update_oauth2_provider — 'update' suggests modifying an OAuth2 provider configuration; description is empty.

POLICY

How to control identity_update_oauth2_provider

PolicyLayer is an MCP gateway — it sits between your AI agents and Amazon Redshift MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for identity_update_oauth2_provider:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "identity_update_oauth2_provider": {
      "limits": [
        {
          "counter": "identity_update_oauth2_provider_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

identity_update_oauth2_provider 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.
