Codexia by Milisp is a free MCP server tool functioning as a lightweight agent workstation designed for AI coding agents. Built with Rust for its desktop backend and TypeScript for its frontend, it offers a platform for managing and interacting with AI-driven development tasks. Codexia supports integration with various AI clients and providers, including OpenAI and Claude, and connects to external agents via the Agent Client Protocol. It provides a set of tools for developers seeking to automate and manage their coding workflows using AI assistance.

What does Codexia connect to?

Codexia acts as a command center for the OpenAI Codex CLI and Claude Code CLI. It integrates with the MCP server marketplace and supports external agents that speak the Agent Client Protocol (ACP). This workstation is compatible with AI clients implementing the OpenAI Codex CLI and Claude Code CLI. It also enables connections to various AI providers such as OpenAI, Anthropic, Gemini, and local models via LM Studio or Ollama, extending its utility across a broad ecosystem of AI development tools.

Core features and tools

Codexia exposes a browser-accessible API in web/headless mode, offering tools such as GET /health, GET /ws for WebSocket streams, and various endpoints for managing codex threads, turns, and models. It includes API access for automation job creation and management, filesystem operations, Git actions, and terminal access. Specific integrations are available through api/cc for Claude and api/notes. The platform supports both HTTP for its REST API and WebSocket for real-time updates and broadcast streams.

Who is it for?

Codexia targets developers and users actively engaged with AI coding agents, especially those who utilize the OpenAI Codex CLI and Claude Code CLI. Its design caters to individuals requiring a centralized environment for managing AI-assisted development tasks and interacting with multiple AI providers. The platform supports automation of development workflows and exploration of codebases. Skip this if you do not work with OpenAI Codex CLI or Claude Code CLI and do not intend to integrate with other AI coding agents.

How to get started

The server authenticates using an API key passed as an environment variable or through a browser-based OAuth flow. For remote MCP servers, access is granted through MCP OAuth.

Use cases

• Interactive AI agent sessions: Launch Codexia, add a project directory, enter a prompt, and initiate an AI agent session for coding tasks.
• Automated task scheduling: Create Agent Task Scheduler jobs for recurring workflows to automate development tasks.
• Codebase exploration and management: Utilize features like Git worktree management, a project file tree, an IDE-like editor, and local web preview for codebase interaction.

Codexia provides a dedicated workstation for managing and automating AI coding agent interactions. It offers extensive API capabilities and broad compatibility with major AI providers and client protocols. The platform is built using modern technologies and is distributed through popular package managers and direct releases. It is a capable tool for developers integrating AI into their coding workflows.
