Install Jentic One Beta

Connect the Compute Engine API to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Compute Engine 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 | sh

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 instance

Jentic 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.

For Agents

Provision VMs, disks, networks, firewalls, and load balancers on Google Cloud across more than 800 endpoints. Lets agents stand up and operate full Compute Engine infrastructure programmatically.

Use for: I need to create a Compute Engine VM, Stop a running VM instance, Resize a managed instance group to handle more load, Create a persistent disk and attach it to an instance

Not supported: Does not run managed Kubernetes, serverless containers, or managed databases - use for IaaS primitives (VMs, disks, networks, load balancers) on Google Cloud only.

Use Cases

Patterns agents use Compute Engine API for, with concrete tasks.

★ Programmatic VM Provisioning

Create Compute Engine VMs from automation, CI/CD pipelines, or platform tooling without going through the Cloud Console. The instances.insert endpoint accepts the machine type, image, network, and metadata, and the API returns a long-running operation that resolves once the VM is RUNNING. This is the core building block for self-service developer environments and ephemeral build runners.

Create a VM named build-runner-42 in us-central1-a from image debian-12 with machine type n1-standard-2 and the default VPC

Managed Instance Group Autoscaling

Operate managed instance groups that scale a stateless web service in response to load. The API exposes resize, recreateInstances, and policy update endpoints so platform teams can codify scale events, rolling restarts, and version rollouts without manual clicks. Most teams keep the autoscaler in charge for normal load and use the API only for surgical interventions.

Resize managed instance group projects/acme/regions/us-central1/instanceGroupManagers/web from 4 to 12 and wait for the operation to complete

Network And Firewall Codification

Define VPCs, subnets, firewall rules, and routes through the API so the network topology is codified rather than clicked together. Compute Engine exposes networks, subnetworks, firewalls, and routers under one API, which keeps Terraform-style automation, drift detection, and disaster recovery rebuilds straightforward.

Create a firewall rule allow-https in the default network that permits TCP/443 from 0.0.0.0/0 to instances tagged web-server

Disk Snapshot Backup And Restore

Snapshot persistent disks on a schedule and restore from them to recover from accidental deletions or corruption. The disks.createSnapshot endpoint takes an incremental snapshot stored in Cloud Storage, and disks.insert with sourceSnapshot creates a new disk from any prior snapshot, giving operators a fast point-in-time recovery path.

Take a snapshot of disk projects/acme/zones/us-central1-a/disks/db-data named db-data-2026-06-10 and store it in the default project

Agent-Driven Infrastructure Operations

An AI agent can run controlled infrastructure operations - restart a stuck VM, expand a disk, or open a firewall port for a debug session - by calling Compute Engine through Jentic. Because Jentic returns the operation schema, the agent can target the exact endpoint it needs out of the 800+ surface area without parsing the discovery doc.

Use Jentic to call instances.reset on projects/acme/zones/us-central1-a/instances/api-server-3 and poll the returned operation until DONE

Key Endpoints

802 endpoints — the compute engine api creates and runs virtual machines on google cloud platform and is one of the largest control surfaces in gcp, covering instances, instance groups, disks, images, networks, subnetworks, firewalls, load balancers, routers, vpns, and global networking primitives.

Why Jentic?

Three things that make agents converge on Jentic-routed access.

Credential isolation

Your Compute Engine OAuth credential is stored once, encrypted, by your own Jentic One instance and injected at execution time. It never enters the agent's prompt, logs, or context.

Intent-based discovery

Agents search Jentic by intent such as 'create a GCP VM' or 'add a firewall rule', and Jentic returns the matching Compute Engine operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

FAQs

Specific to using Compute Engine API through Jentic.

What authentication does the Compute Engine API use?

It uses Google OAuth 2.0 with scopes such as https://www.googleapis.com/auth/compute and the broader cloud-platform scope. Through Jentic the OAuth credentials are stored encrypted in your Jentic One instance and the agent receives only short-lived access tokens at execution time.

Can I create and start a VM with a single API call?

Yes. Send a POST to /compute/v1/projects/{project}/zones/{zone}/instances with the machine type, source image, network interface, and metadata. The endpoint returns a long-running operation that resolves once the VM transitions to RUNNING.

What are the rate limits for the Compute Engine API?

Compute Engine enforces per-project read and write quotas per minute, with regional resource quotas (CPUs, IPs, disks) governing actual provisioning. Heavy automation should batch reads, use list pagination, and respect the operation polling backoff so you do not exhaust the per-minute control-plane budget.

How do I provision a VM through Jentic?

Search Jentic for 'create gcp vm', load the instances.insert schema, and execute the call against /compute/v1/projects/{project}/zones/{zone}/instances with the machine type, source image, and network. Jentic returns the schema so the agent fills only the required fields out of Compute Engine's 800+ endpoint surface.

Is the Compute Engine API free?

The API has no per-call charge - you pay only for the underlying resources you create such as VM-hours, persistent disks, and egress. Free-tier credits cover small e2-micro instances in eligible regions.

How do I take a disk snapshot for backup?

Call POST on /compute/v1/projects/{project}/zones/{zone}/disks/{disk}/createSnapshot with a name and labels. Snapshots are incremental and stored in Cloud Storage, and a new disk can be created from any snapshot via disks.insert with sourceSnapshot.

Can I limit what my agent is allowed to do with the Compute Engine API?

Yes. Because you run Jentic One yourself, your own rules decide which Compute Engine operations and credentials the agent may use. Compute Engine puts the project, zone, and instance ids in the URL path, such as /projects/{project}/zones/{zone}/instances/{instance}/reset, so you can pin the agent to a single project where it may only create and list instances and nothing else. Operations like instance reset, firewall creation, or disk snapshots are excluded unless you explicitly add them to the agent's allowed set.
