overview

What is OneCLI?

OneCLI is an AI agent harness tool developed by Jonathan Fishner that enables teams and employees to securely automate tasks using AI agents. It provides a secured, sandboxed environment for AI agents, managing secrets and permissions without the agents directly handling sensitive information like API keys or passwords.

features

Key Features of OneCLI

OneCLI provides a robust set of features focused on secure and managed AI agent deployment for organizational use. Its architecture ensures that AI agents can interact with external services while adhering to strict security protocols and operational policies.

use cases

Who Should Use OneCLI?

OneCLI is designed for organizations and teams that require secure and controlled deployment of AI agents across their workforce. It addresses the challenges of integrating AI automation with existing security policies and credential management.

  • Teams and Every Employee: For securely giving AI agents access to external services without exposing raw keys, enabling personal, secured AI agents.
  • Operations & Business Teams: For automating business workflows such as CRM hygiene, lead sourcing, meeting scheduling, and managing company lifecycles.
  • IT & Platform Teams: For managing secrets and permissions for AI agents, enforcing policies, and providing full audit logs for AI agent activities.
  • Developers using Coding Agents: For building and extending CLI applications with a robust foundation, including support for sub-commands and rich output formatting.

how to use

How to Use OneCLI

OneCLI can be deployed as an open-source platform, allowing teams to self-host and integrate it into their existing infrastructure. It functions by intercepting agent requests and injecting credentials at a proxy layer after authorization.

  • 1Deploy OneCLI using Docker for self-hosting, as detailed in a guide published on DEV Community on March 28, 2026.
  • 2Configure and manage secrets and permissions for AI agents within the OneCLI platform.
  • 3Integrate AI agents with OneCLI to enable secure access to external services like GitHub, Gmail, Notion, and Dropbox.
  • 4Define policies and guardrails for agent actions, including human approval for critical operations.
  • 5Monitor AI agent activities through comprehensive audit logs provided by OneCLI.

pricing

OneCLI Pricing & Plans

OneCLI operates on a freemium model, offering a trial period for users to evaluate its capabilities before committing to a paid plan. Specific long-term pricing tiers beyond the trial are not publicly detailed.

  • Free Trial: Free for 7 days, includes $5 in AI credits.

Pros

  • +Provides a highly secure, sandboxed environment for AI agents, preventing direct access to sensitive credentials.
  • +Open-source architecture allows for full transparency, auditability, and self-hosting capabilities.
  • +Enables deterministic human approval for critical AI agent actions, enhancing control and safety.
  • +Offers comprehensive audit logs for all AI agent activities, supporting compliance and oversight.
  • +Facilitates team collaboration by allowing individual sandboxed agents for each employee under centralized policy control.
  • +Reduces command latency by up to 30% due to performance optimizations in recent updates.

Cons

  • Specific long-term pricing tiers beyond the 7-day free trial are not extensively detailed.
  • Requires initial setup and configuration for self-hosting, which may involve technical expertise.
  • While open-source, the community support and ecosystem might be less mature compared to established enterprise automation tools.
  • The focus on secure agent access might introduce a slight overhead compared to direct API integrations for less sensitive tasks.
  • Integration with a wide array of niche or legacy systems might require custom development due to its specific agent harness model.

Similar Tools

OneCLI vs Competitors

OneCLI distinguishes itself in the automation and AI agent landscape through its dedicated focus on secure, sandboxed environments and robust credential management, particularly for team-based AI agent deployments.

1
Fabric

A Python library and command-line tool for streamlining the use of SSH for application deployment or system administration tasks.

Fabric focuses heavily on remote execution via SSH, which aligns with secure agent concepts. It requires Python knowledge and manual integration for advanced sandboxing or credential management beyond SSH keys, whereas OneCLI aims for a more out-of-the-box secure agent experience.

2
Invoke

A Python task execution tool and library, allowing you to define and run Python functions as command-line tasks.

Invoke is a general-purpose task runner, similar to how OneCLI automates tasks, but it's Python-centric. It doesn't inherently provide the 'secured sandboxed agent' features of OneCLI, requiring the user to implement security best practices within their Python tasks.

3
Task

A simple, YAML-based task runner written in Go, designed to replace `Makefile` for project-specific automation.

Task provides a straightforward way to define and run commands, similar to OneCLI's task automation. However, it lacks the built-in 'secured sandboxed agent' features and explicit credential management that OneCLI emphasizes, relying on the underlying system's security.

4
Ansible

An open-source automation engine that automates software provisioning, configuration management, and application deployment.

Ansible is a much broader and more powerful automation tool, offering robust credential management (Ansible Vault) and execution control, which aligns with OneCLI's security focus. However, it has a steeper learning curve and is designed for infrastructure-level automation, potentially being overkill for simple employee task automation compared to OneCLI's more focused agent approach.

5
Shell Scripts (e.g., Bash)

Native scripting capabilities of Unix-like operating systems for automating command-line tasks.

Shell scripts are the most fundamental and universally available CLI automation method, offering complete flexibility. The trade-off is that they require manual implementation of any security, sandboxing, or credential management, which OneCLI aims to provide as a built-in feature.
