Open-source enterprise agent harness

CUGA for real enterprise work

CUGA is the open-source agent runtime behind the Crafted AI Framework. Start with a benchmark-proven generalist harness, then configure domain tools, MCP servers, policies, reasoning modes, and deployment paths without rebuilding planning, orchestration, browser control, and governance from scratch.

Core Capabilities

The pieces enterprises usually have to assemble themselves, already wired into a configurable harness.

OpenAPI, MCP & LangChain tools

Wire existing REST APIs, MCP servers, and Python functions into one agent runtime without rebuilding orchestration.

Reasoning modes

Tune CUGA for fast, balanced, accurate, or experimental save-and-reuse runs depending on cost and reliability needs.

Hybrid API + browser execution

Use APIs for system data, then operate web interfaces with Playwright and the CUGA browser extension in the same task.

Policies and human approval

Configure Intent Guard, Playbook, Tool Approval, Tool Guide, and Output Formatter policies with HITL checkpoints.

Supervisor and remote agents

Compose CUGA as a worker, supervisor, or remote A2A collaborator for nested workflows and multi-agent execution.

Manage, publish, and audit

Draft tools, MCP servers, LLM choices, and policies in the manager UI, test them, then publish versioned configs.

Crafted AI Framework foundation

CUGA is the engine layer. Crafted turns it into shipped agents.

The Crafted AI Framework does not start from a blank agent scaffold. It uses CUGA as the governed runtime underneath, then adds the product work around it: domain modeling, tool contracts, deployment topology, evaluation loops, and the user-facing control plane.

CUGA runtime

The execution engine

CUGA supplies the agent loop: planning, tool selection, API calls, browser actions, memory hooks, approvals, and run visibility.

Crafted AI Framework

The product layer

Crafted wraps that runtime with reusable deployment patterns, domain templates, evaluations, operating surfaces, and managed implementation support.

Your workflow

The business system

Your tools, policies, data, and user experience become a governed agent that can run inside real enterprise processes.

Enterprise Use Cases

CUGA is strongest where the task crosses systems, interfaces, policies, and steps.

API-to-web workflows

Fetch account or operational data from APIs, then update the right web page, form, or internal console.

Digital sales updatesCRM enrichmentBack-office actions

Tool-rich enterprise agents

Coordinate OpenAPI services, MCP tools, and runtime LangChain functions in a single task plan.

Service integrationFilesystem operationsEmail and support tools

Governed execution

Pause at critical decisions, inspect planned actions, and require approval before sensitive tools run.

Tool approvalsIntent guardrailsPolicy-driven answers

Reusable domain playbooks

Package domain procedures as SKILL.md files so the agent loads full instructions only when a task needs them.

Compliance playbooksOps runbooksAnalyst workflows

Planner-executor + CodeAct

Structured planning, code execution, and smart variable management help CUGA handle long, multi-step tasks.

SDK and CLI friendly

Run demos with the CLI, embed CUGA from Python, or pass runtime tools directly when CUGA lives inside your app.

Optional memory

Enable memory when the workflow needs continuity, then keep lighter stateless runs for simpler automation.

Langflow integration

Use CUGA in low-code visual workflows when teams need to design and ship agent flows quickly.

Cluster-ready self-hosting

Deploy with included Docker assets, Helm chart, and scripts for local or cloud Kubernetes clusters.

Trajectory visibility

Inspect agent trajectories, tool calls, and decisions with the visualization dashboard after a run.

Why CUGA?

A practical comparison for teams deciding whether to build an agent stack or start with a harness.

Put CUGA behind your Crafted AI Framework deployment.

Crafted helps teams turn the open-source CUGA harness into production domain agents: tool wiring, policy design, evaluation, deployment, and the operating surface your users actually need.
