For Agents

Manage Azure Arc-enabled servers as Azure resources — list machines, install or update machine extensions, and trigger reconnects.

Connect the HybridComputeManagementClient to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the HybridComputeManagementClient, or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.

Install Jentic One Beta (Self-Hosted)

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

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.

View OpenAPI Document

Jentic publishes the only available OpenAPI document for HybridComputeManagementClient, keeping it validated and agent-ready.

Jentic publishes the only available OpenAPI specification for HybridComputeManagementClient, keeping it validated and agent-ready. The Azure Hybrid Compute Management API manages Azure Arc-enabled servers — the resource projection that makes on-premises and other-cloud machines first-class Azure resources. It exposes machine and machine-extension lifecycle operations alongside a reconnect endpoint used when an agent needs to re-onboard a machine. Authentication is Azure AD OAuth2 against management.azure.com, scoped under Microsoft.HybridCompute.

Use Cases

Patterns agents use HybridComputeManagementClient API for, with concrete tasks.

★ Hybrid fleet inventory

List Arc-enabled machines across a subscription via GET /subscriptions/.../providers/Microsoft.HybridCompute/machines, returning an inventory of on-prem and other-cloud servers projected into Azure. Combine with the resource-group-scoped list to filter by environment. Useful for hybrid CMDB sync and licensing audits.

GET /subscriptions/{sub}/providers/Microsoft.HybridCompute/machines and return each machine's name, OS, and connection state.

Standardise extensions across hybrid hosts

Install or update machine extensions on every Arc machine via PUT /subscriptions/.../machines/{name}/extensions/{extensionName}. Useful for rolling out the Microsoft Monitoring Agent or DSC across a hybrid fleet so every machine reports telemetry. PATCH the same path to upgrade an extension version.

PUT /subscriptions/{sub}/resourceGroups/hybrid-rg/providers/Microsoft.HybridCompute/machines/datacenter-01/extensions/MMAExtension with the agreed agent settings, then poll until provisioningState is Succeeded.

Decommission and reconnect flows

When a server is retired, DELETE its Arc record via /subscriptions/.../machines/{name}. When an agent loses connection but the machine is still alive, POST .../machines/{name}/reconnect to refresh credentials and rejoin Arc. These operations bracket the lifecycle that field operators care about most.

POST /subscriptions/{sub}/resourceGroups/hybrid-rg/providers/Microsoft.HybridCompute/machines/datacenter-01/reconnect to bring the machine back into Arc inventory.

AI agent hybrid operations via Jentic

An infrastructure agent uses Jentic to sweep Arc-enabled servers, ensure the right extensions are installed, and trigger reconnects when machines drop out. Jentic resolves natural-language intents to the correct ARM operation and injects a scoped bearer token at execution time.

Use Jentic to search for 'install machine extension on azure arc', load MachineExtensions_CreateOrUpdate, and apply MMAExtension to every Arc machine in resource group 'hybrid-rg'.

Why though Jentic?

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

Credential isolation

Azure service principal credentials sit encrypted in the Jentic vault. Agents receive a scoped Azure AD bearer token at execution time and never see the raw client secret.

Intent-based discovery

Agents search Jentic for 'list azure arc machines' or 'install azure arc extension' and Jentic returns the matching Machines or MachineExtensions operation with its full input schema.

Time to first call

Direct ARM integration: 1-2 days for AAD setup, async polling, and per-extension input shapes. Through Jentic: under 30 minutes — search, load schema, execute.

Related APIs

Alternatives and complements available in the Jentic catalogue.

Alternative

Azure Compute Management

Manages native Azure VMs and their VM extensions.

Use Azure Compute when the machine in question is a native Azure VM rather than an Arc-enabled on-prem or other-cloud server.

Complementary

Azure Guest Configuration

Apply in-guest configuration baselines, including on Arc-enabled servers.

Pair with Hybrid Compute when the agent needs to enforce baseline configuration on Arc machines after extensions are installed.

Complementary

Azure Policy

Define policies that enforce required extensions across Arc machines.

Use Azure Policy when the agent should declaratively require an extension on every Arc machine rather than imperatively install it.

FAQs

Specific to using HybridComputeManagementClient API through Jentic.

Why is there no official OpenAPI spec for HybridComputeManagementClient?

Microsoft Azure does not publish a stand-alone OpenAPI specification for the 2019-12-12 Hybrid Compute management surface. Jentic generates and maintains this spec from the Microsoft.HybridCompute ARM surface so that AI agents and developers can call HybridComputeManagementClient via structured tooling. It is validated against the live API and kept up to date. Get started at https://app.jentic.com/sign-up.

What authentication does this API use?

It uses Azure AD OAuth2 against management.azure.com, declared as the azure_auth security scheme. Through Jentic, your service principal credentials sit encrypted in the vault and are exchanged for a scoped bearer token at execution time.

Does this API onboard new servers to Arc?

No. The initial onboarding handshake is performed by the Azure Connected Machine agent on the server itself, which calls into Azure to register. This management API operates on the resulting Microsoft.HybridCompute/machines record. Use POST /subscriptions/.../machines/{name}/reconnect when a known machine has lost its agent connection and needs to refresh.

What are the rate limits?

Standard ARM throttles apply at the subscription level — about 12,000 reads and 1,200 writes per hour per subscription. Bulk extension installs across a large fleet should batch and back off on 429 responses.

How do I install a machine extension on every Arc machine through Jentic?

Run jentic.search('install extension on azure arc machine'), load the MachineExtensions_CreateOrUpdate schema, and execute it for each machine with the extension name and properties. Iterate over the list returned by Machines_ListBySubscription to cover the whole fleet.
