DevSpace

Bring a Codex-style coding workflow to ChatGPT.

Give ChatGPT a secure connection to your own machine and Turn ChatGPT into Codex

DevSpace is a self-hosted MCP server that lets ChatGPT read, edit, search, and run code in your real local projects — your files, your tools, your terminal — without uploading anything to a third party. You run it on your machine, expose it through a tunnel you control, and approve the connection with a password only you have.

Installation

DevSpace requires Node >=20.12 <27. Node 22 LTS is recommended.

Install the DevSpace CLI:

npm install -g @waishnav/devspace

Then initialize and start the server:

devspace init
devspace serve

Or run it without a global install:

npx @waishnav/devspace init
npx @waishnav/devspace serve

During setup, DevSpace asks for:

• the local project folders ChatGPT is allowed to open through DevSpace
• the local port, usually 7676
• your public HTTPS base URL from Cloudflare Tunnel, ngrok, Pinggy, Tailscale Funnel, or another reverse proxy

Use the public origin without /mcp during setup:

https://your-tunnel-host.example.com

You will configure your MCP client with the public /mcp URL after setup.

When the client connects, DevSpace opens an Owner password approval page. Enter the Owner password printed by devspace init. It is also stored in:

~/.devspace/auth.json

Keep that password private.

Connect Your MCP Client

The default local endpoint is:

http://127.0.0.1:7676/mcp

Most users should connect through a public HTTPS tunnel:

https://your-tunnel-host.example.com/mcp

What ChatGPT Can Do

Once connected, ChatGPT can open one of your approved project folders as a workspace. From there, it can inspect the repo, make scoped edits, run commands, and show you what changed.

DevSpace gives ChatGPT tools to:

• read, write, and edit files inside the opened workspace
• search code and inspect directories
• run shell commands for tests, builds, git, and package scripts
• use isolated Git worktrees for parallel coding sessions
• follow project instructions from AGENTS.md and CLAUDE.md
• discover local agent skills from your skill folders
• show tool cards and optional change summaries in ChatGPT Apps-compatible hosts

Mental Model

DevSpace is remote access to selected local folders.

You decide which roots are allowed. The MCP client still has powerful local capabilities inside an opened workspace, including shell execution. Treat a connected client like a trusted coding partner with access to your machine.

For a normal ChatGPT coding session:

1. Start your tunnel.
2. Run devspace serve.
3. Connect the MCP client to your public /mcp URL.
4. Approve the connection with the Owner password.
5. Ask ChatGPT to open a project inside one of your allowed roots.

Platform Support

DevSpace supports Linux, macOS, and Windows environments with a Bash-compatible shell.

Platform	Status	Notes
Linux	Supported	Requires Node, npm, Git, and Bash.
macOS	Supported	Requires Node, npm, Git, and Bash.
Windows with Git Bash, WSL, MSYS2, or Cygwin Bash	Supported	Git Bash is the simplest native Windows setup.
Windows PowerShell or cmd.exe only	Not supported yet	Install Git Bash or use WSL.

Run this to inspect your local setup:

devspace doctor

Philosophy

Every piece of software is becoming conversational. Natural language is redefining how we interact with tools, workflows, and systems.

My bet is that ChatGPT becomes the operating system for everything. Once we reach AGI, we will simply talk to ChatGPT, and it will prompt, coordinate, and orchestrate sub-agents that set up the right loops for us.

We are not there yet.

DevSpace is one attempt to fast-forward that future: a way for MCP-capable hosts like ChatGPT and Claude to work directly with local project files through explicit, inspectable tools.

Local Development

For working on DevSpace itself:

npm install --include=dev
npm run dev
npm run typecheck
npm test
npm run build
npm run start
