DevSpace is a self-hosted MCP server that brings Codex-style coding workflows to ChatGPT and other AI agents.
The tool solves the problem of giving AI assistants secure access to your local codebase and development environment without uploading files to third-party services. It works by running as an MCP server on your machine, exposing a controlled endpoint through a reverse proxy tunnel you manage, and requiring password approval for each client connection. This lets ChatGPT or other coding agents read, edit, search, and execute code in your real projects using only tools and files on your own system.
DevSpace suits developers who want to use ChatGPT as a coding assistant while keeping their source code local and private. It works for both direct ChatGPT integration and as a backend for coding agents that delegate work through it. The setup process distinguishes between where you invoke DevSpace from and which agents it may use as subagents, allowing flexible configurations for different workflows. For ChatGPT users, you specify which local project folders are accessible and provide a public HTTPS URL from a tunnel service of your choice. For coding-agent-only setups, it operates against the current Git project or directory without requiring tunnel configuration.
The project maintains active CI automation and publishes to npm. Development activity shows consistent attention to protocol compatibility, including automatic support for both current and older MCP protocol versions through stateless handling at a single endpoint, with no manual configuration required.
