For Agents
Programmatically create, list, and update GCP projects, folders, organizations, and tags, plus manage IAM bindings on those resource containers. Lets agents structure tenancy and apply policy across a Google Cloud hierarchy.
Use for: I need to create a new Google Cloud project under a folder, List all folders my service account can access, Search for projects whose display name contains a keyword, Get the IAM policy attached to a specific organization
Not supported: Does not provision compute, storage, or networking resources, and does not manage service account keys — use for the GCP project, folder, organization, and tag hierarchy only.
The Cloud Resource Manager API creates, reads, and updates metadata for Google Cloud Platform resource containers including projects, folders, organizations, tag keys, and tag values. It exposes hierarchical IAM controls for managing access to those containers and supports lien protection to prevent accidental project deletion. Resource Manager is the foundation for organizing GCP resources at scale and underpins billing, policy enforcement, and asset inventory across the platform.
Install Jentic One Beta
Connect the Cloud Resource Manager API to your agent
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Cloud Resource Manager API, or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.
Two steps, two machines. Install the instance in a safe environment, then register your agent from wherever it runs.

Step 1: Jentic One Host machine
# On the machine that will host your Jentic One instance:
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh2
Step 2: Agent machine
# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh
jentic register # connects your agent to your Jentic One instanceJentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.
Capabilities
What an agent can do with Cloud Resource Manager API.
Create and undelete GCP projects under a parent folder or organization
Search and list folders, organizations, and projects accessible to the caller
Get, set, and test IAM policies on projects, folders, and organizations
Apply tag keys and tag values to resources for policy and billing segmentation
Place liens on projects to prevent unintended deletion
Look up effective tags inherited through the resource hierarchy
Use Cases
Patterns agents use Cloud Resource Manager API for, with concrete tasks.
★ Programmatic Project Provisioning
Automate the creation of new Google Cloud projects for each customer, environment, or workload. Cloud Resource Manager exposes project create, get, and update operations alongside folder placement so platform teams can spin up isolated tenants on demand and attach the correct billing account and tags. End-to-end provisioning typically completes in under a minute per project.
Create a new project named acme-prod-eu under folder folders/12345 and tag it with environment=production
Hierarchy-Wide IAM Audit
Enumerate organizations, folders, and projects to retrieve their IAM policies and identify over-permissioned principals or stale bindings. Cloud Resource Manager pairs search endpoints with getIamPolicy on every container, giving compliance teams a single source for hierarchy-wide access reviews without scraping the console.
Iterate through every project in organizations/9999 and return any binding granting roles/owner to a non-corporate identity
Tag-Driven Cost Allocation
Apply tag keys and tag values to projects and folders so billing exports and policy controls can group spend by team, product, or environment. Cloud Resource Manager creates tag bindings programmatically, letting finance and platform teams roll out a consistent tagging taxonomy across thousands of projects without manual click-ops.
Create tag value tagValues/cost-center-42 under tag key environment and bind it to project projects/acme-prod-eu
Agent-Driven Landing Zone Setup
An AI agent invoked through Jentic can stand up a complete landing zone by calling Cloud Resource Manager to create the folder structure, provision projects, and apply baseline IAM and tag policies. Because Jentic returns the operation schema directly, the agent does not need to crawl Google's discovery docs to build each request.
Use Jentic to search 'create gcp project', load the projects.create schema, and provision three projects under folders/dev, folders/stage, and folders/prod

Why Jentic?
Three things that make agents converge on Jentic-routed access.
Credential isolation
Google OAuth 2.0 client credentials and refresh tokens for Cloud Resource Manager are encrypted in the Jentic vault. Agents receive scoped, short-lived access tokens at execution time — long-lived secrets never enter the agent context.
Intent-based discovery
Agents search Jentic with intents like 'create a gcp project' or 'set iam policy on folder' and Jentic returns the matching Resource Manager operation along with its request schema, so the agent calls the correct endpoint without parsing Google's discovery document.
Time to first call
Direct integration with Cloud Resource Manager: 1-3 days for OAuth setup, scope review, and long-running operation polling. Through Jentic: under 1 hour — search, load schema, execute.

FAQs
Specific to using Cloud Resource Manager API through Jentic.
What authentication does the Cloud Resource Manager API use?
It uses Google OAuth 2.0 with scopes such as https://www.googleapis.com/auth/cloud-platform and https://www.googleapis.com/auth/cloud-platform.read-only. Through Jentic, the OAuth refresh token and client secret are stored in the Jentic vault and never exposed to the agent runtime.
Can I create new GCP projects with the Cloud Resource Manager API?
Yes. Send a POST to /v3/projects with the parent folder or organization, a project ID, and a display name. The endpoint returns a long-running operation that you can poll until the project is fully provisioned.
What are the rate limits for the Cloud Resource Manager API?
Google enforces per-project read and write quotas on Resource Manager, with mutating operations like project creation and IAM policy updates limited far more aggressively than reads. Run heavy hierarchy scans against the search endpoints with backoff and request quota increases for large landing-zone rollouts.
How do I apply tag bindings to a project through Jentic?
Search Jentic for 'apply tag binding to gcp project', load the tagBindings.create schema, and execute a call against /v3/tagBindings with the parent project resource name and the tag value. Jentic returns the input schema so the agent can fill the required fields without reading Google's discovery doc.
Is the Cloud Resource Manager API free?
The API itself has no per-call charge — you only pay for the underlying Google Cloud resources you create. Quota limits apply at the project level even when usage is free.
How does the API handle deletion protection?
Place a lien on a project via /v3/liens to block deletion until the lien is removed. Liens are useful guard rails when an agent or CI pipeline has broad project-write permissions but you want explicit confirmation before destructive actions.
