# Agentic AI Architecture

Design multi-agent systems that hold up in production, not just in the demo.

Architecture for agents that plan, call tools and hand off work, with the controls to run them at enterprise scale.

The Challenge

Most agent projects start as one prompt and a few tools. As tasks grow, agents loop, call the wrong tool or lose context, and nobody can say why a run failed.

The architecture

## Agents that fail safely and still finish the job.

Platforms we work with

## We build on the agent stack you've chosen.

What stays the same

- Your cloud, identity and security controls
- Your data sources and system permissions
- The tools your teams already use

What changes

- One architecture pattern across teams
- Every agent run traced and replayable
- Clear limits on what each agent can do

### LangGraph and LangChain

For stateful, multi-step agents with explicit control flow, checkpoints and human-approval steps.

### Amazon Bedrock, Azure AI Foundry and Google Vertex AI

Managed agent and model services inside the cloud you already run, under your existing security controls.

### Model Context Protocol (MCP)

A standard way to connect agents to tools and data, so new systems plug in without custom glue code.

### Your own services and APIs

Agents call the systems you already have, with the same permissions and audit trail as your people.

What the agent does

## From signal to action, with your team in control.

### Map the work

Route each workflow, plan decisions, and decide which need an agent and which need plain code.

### Choose the pattern

Single agent, planner-checker, or a supervised team, picked for the task, with clear limits on each agent.

### Connect tools and data

Tool calls, schemas and memory designed with permissions, timeouts and fallbacks.

### Make it observable

Every run stored step-by-step, so history can be replayed and fixed.
