AI agents for IT: Types, examples, and design practices

Traditional automation follows an effective, straightforward logic, but it lacks the flexibility to manage the nuance of a modern enterprise. If there’s ever a new process or an edge case, scripts break. That’s where AI agents change the equation.

Unlike a static script, AI agents for IT are goal oriented. Instead of following a set of instructions, they use large language models (LLMs) to understand intent, evaluate the environment, and determine the best course of action. For IT teams, this means moving beyond simple ticket routing toward independent AI agents that resolve complex issues end to end.

In this guide, we explain AI agents, common different types, and ways to implement them.

What’s an AI agent?

An AI agent is autonomous software that observes its environment and takes actions to achieve a specific goal. In the context of IT, this means the AI can independently answer questions and solve issues. These tools move beyond being a repository of information (like a knowledge base) or a communication interface (like a chatbot).

AI agents aren’t simple pre-programmed automation. Traditional automation is fragile because it’s linear and must follow the same procedure. For instance, if a UI element changes or an API returns an unexpected error, the process stops. But we only have to explain AI agents through their operational loop to show how much more resilient they are:

• Perception: The agent ingests the request (usually a Slack message or ticket) and checks the current state of the system, like Okta logs or Jira status.

• Reasoning: The AI determines the gap between the current state and the goal.

• Action: The agent executes a tool call, like a Python script or an API request.

• Observation: The AI evaluates the result. If it sees that the action failed, it can reiterate and try an alternative path.

Why IT teams are adopting agents

Many IT departments balance increasing ticket volumes and the pressure to maintain lean headcounts. Agents ease these capacity constraints while accelerating resolution time and leaving a clean audit trail. Let’s take a closer look.

Eliminating the access request backlog

Manual software provisioning puts a big strain on IT resources. An autonomous AI agent can verify identity, check peer access, and grant permissions in seconds. This end-to-end resolution removes the wait time present in human-managed queues. Mercor is a great example. This AI training company used Serval to automate over 60% of tickets, including database-access and onboarding requests.

Reducing mean time to resolution

Because agents act the moment a request is made, resolution is nearly instantaneous. This is a fundamental shift from reactive IT to real-time service. By automating routine, low-complexity tasks, IT leaders can refocus their human talent on high-value projects like security posture and infrastructure architecture. Perplexity, an AI answer engine, demonstrates how AI-native service management allows rapid growth without a linear increase in IT costs. Vernon Man, head of IT, says Serval allowed their small team to keep up with IT demands as the company scaled threefold.

Improving data accuracy and auditability

Humans can struggle with consistent logging; it simply slips through the cracks in a busy workday. But agents log every action, tool call, and conversation automatically. This provides a clean, structured audit trail that facilitates SOC2 compliance and internal reviews.

Types of AI agents in the enterprise

An AI agent’s complexity depends on its underlying logic and information processing. Here are the most common types of AI agents to help you decide which architecture fits your specific use cases.

1. Reactive agents

These are the simplest forms of agents. They operate by responding to specific inputs based on predefined rules. They don’t have memory of past events and only act on the system’s immediate state. They’re highly reliable for simple tasks, like provisioning software and resetting passwords.

2. Context-aware agents

These agents use a memory of recent interactions to inform decision making. If an employee asks a follow-up question, a context-aware agent uses the conversation history to provide a relevant answer. For example, these agents excel in help desk interactions where users might provide information in stages.

3. Adaptive agents

These agents learn from their environment. If a particular action fails to resolve a ticket, an adaptive agent refines its approach for future requests. This allows the AI system to get smarter over time without an admin manually updating every workflow.

4. Goal-driven agents

These AI agents focus on a specific outcome. They evaluate different paths to reach a goal and choose the most efficient one based on the tools available. They can handle multi-step workflows where the exact path might vary. For instance, if the goal is "onboard this employee," the AI agent executes distinct actions depending on the person’s role or department.

5. Utility-based agents

Utility-based agents go a step beyond goal seeking. They evaluate multiple ways to achieve a goal and choose the one that provides the highest efficiency, like the path that uses the fewest API calls or costs the least in compute resources.

6. Hierarchical and multi-agent systems

In an enterprise environment, a single agent rarely does everything. Multi-agent systems deploy specialized intelligent agents that work together under a shared system of record. Serval illustrates this through a three-agent model:

• The Automation Agent: Generates workflows from plain-English descriptions

• The Help Desk Agent: Interacts with employees, identifies intent, and executes workflows

• The Insights Agent: Works in the background to analyze patterns and surface new automation opportunities

Serval provides department-specific ticket queues, knowledge sources, and workflows under a shared system of record. Different teams, from IT and security to HR and finance, receive unified yet distinct support. This lets AI agents execute relevant actions across the company, enabling simple cross-team deployment.

Implementation: AI agent examples in IT

To see how this AI works in practice, look at the difference between a legacy workflow and an agentic one.

The legacy pattern

An employee loses their laptop. They file a ticket, which an AI agent routes to a team member. A technician reads the issue a few hours later. They then find the user in a spreadsheet and check the inventory in another tool, then email the employee to confirm the shipping address.

This process is still primarily manual. The agent is simply a tool that deflects issues to human professionals.

The agentic pattern

The employee reports the lost laptop in Slack. The AI agent immediately identifies the intent. It checks the user’s asset history in the internal database and cross-references the inventory in their procurement system. It then asks the employee to confirm their address. Finally, the agent requests approval from an asset coordinator before triggering a shipping label via the courier’s API. The entire process takes about 90 seconds.

Agent challenges and ways to design around them

Deploying autonomous systems requires a focus on safety and auditability. Without the right architecture, agents can create automation debt or security vulnerabilities. Here are the main obstacles to consider.

Agents acting outside their intended scope

The risk of an agent performing an unauthorized action is a common concern. This typically happens in platforms that lack control. For instance, an AI agent with broad permissions, access to tools, and allowed actions doesn’t have tight boundaries restricting performance.

A well-designed system separates the agent that builds the automation from the agent that runs it, which reins in control. In Serval’s architecture, the Automation Agent writes the code, but the Help Desk Agent can only invoke tools within strict rules set by a manager.

Approval gaps on sensitive operations

Some tasks, like granting admin access to a production environment, should never be fully autonomous. The design answer is to treat approval workflows as a first-class configuration. Every workflow should have the option to require a human review before execution. Serval’s access management module supports custom approval logic, like checking peer access in Okta before returning a decision.

The “triage-only” trap

Some ITSM platforms claim to offer AI agents but simply bolt a chatbot onto legacy architecture. While these agents can route tickets or summarize them, they can’t resolve them end to end. Real efficiency requires an AI-native platform where the agent has deep, programmatic access to the underlying infrastructure.

Poor audit trails

Black box AI conceals its thought process and decision-making logic. This lack of traceability complicates audit trails and troubleshooting. Serval offers detailed, auditable workflows with complete conversation and action logs. Teams can access full records for compliance and review’s sake and use traces to solve common errors.

Build an agentic architecture with Serval

Moving to an agentic model changes the IT department’s main goals. Instead of managing high volumes of individual tickets, teams focus on managing the workflows that resolve them. With AI agents, technical debt doesn't accumulate in a manual queue, and human teammates concentrate on high-priority tasks.
