Manages access control across Resource Manager resources (Organization, Folder, Project) and individual resources. Use when creating, updating, listing, or deleting IAM allow policies or deny policies. Don't use for access denial troubleshooting (use iam-helper-for-troubleshooting), temporary privileged access (use iam-helper-for-privileged-access-management), configuring VPC Service Controls, or managing network firewall rules.

IAM Helper for Policy Management
Orchestrates the lifecycle and management of IAM allow and deny policies across
IAM v1 (allow policies) and IAM v2 (deny policies).
Core Concepts & Paradigms
IAM operates across two policy paradigms:
- IAM v1 (Allow Policies): Grants roles to principals (users, service
accounts, groups, domains) on specific resources. Supports Resource Manager
resources (organizations, folders, projects) as well as individual resources
across supported Google Cloud services. - IAM v2 (Deny Policies): Sets explicit organization-, folder-, or
project-level guardrails that prevent specified principals from using
designated permissions, regardless of any allow policies granted. Evaluated
before allow policies.
Workflow & Decision Tree
When receiving a policy management request, determine whether the operation is
Read-Only or Mutating, and whether it targets IAM v1 (Allow
Policies) or IAM v2 (Deny Policies):
1. Read-Only Operations (Autonomous Execution)
Read-only actions include the following:
- IAM v1 Allow Policies:
get-iam-policyon project/folder/organization,
orgcloud iam list-testable-permissions //cloudresourcemanager.googleapis.com/projects/PROJECT_ID. - IAM v2 Deny Policies:
gcloud iam policies listorgcloud iam policies getwith--attachment-pointand--kind=denypolicies.
For read-only actions, execute the command autonomously to inspect state, and
present the query results clearly to the user.
2. Mutating Operations (Plan & Confirm Protocol)
Mutating operations include the following:
- IAM v1 Allow Policies:
add-iam-policy-binding,
remove-iam-policy-binding, orset-iam-policyacross project, folder,
organization, or resource levels (see
references/v1-allow-policies.md). - IAM v2 Deny Policies:
create,update, ordeletedeny policies on
attachment points
(cloudresourcemanager.googleapis.com/projects/PROJECT_ID,
cloudresourcemanager.googleapis.com/folders/FOLDER_ID, or
cloudresourcemanager.googleapis.com/organizations/ORG_ID) using YAML/JSON
policy files (see
references/v2-deny-policies.md).
For mutating operations, follow the Plan & Confirm Protocol below. DO
NOT execute mutating commands autonomously without prior user approval.
Execution & Safety Protocol
- Plan and Confirm (No Autonomous Mutation): Mutating allow and deny
policy changes modify live security perimeters and access controls. You MUST
NOT execute mutatinggcloudcommands directly via tool calls without
explicit prior confirmation from the user. When asked to apply a mutating
change, do the following:- Formulate the Command: Generate the exact, fully constructed
gcloudcommand (including all parameters such as--member,--role,
--attachment-point,--kind=denypolicies, and--policy-file). - Warn of Impact & Propagation: Issue a general warning that the
change could impact access in a live environment and takes time to
propagate across Google Cloud global infrastructure. - Request User Confirmation: Prompt the user for approval before
applying the changes to the live environment.
- Formulate the Command: Generate the exact, fully constructed
- Post-Execution Verification: After the user approves and the mutating
policy change is executed, run the corresponding verification command (see
references/v1-allow-policies.md and
references/v2-deny-policies.md for exact
verification steps) to verify that the active state matches expectations
before reporting completion. - Security Guardrail (Public & Blanket Access Refusal): Never grant
allUsersorallAuthenticatedUsersbasic roles (roles/owner,
roles/editor,roles/viewer,roles/admin,roles/writer, and
roles/reader) or broad permissions. Explicitly refuse blanket public
access requests, explain the severe security risks of public project
ownership/access, and propose scoped, least-privileged role bindings for
specific authenticated identities instead.
