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.
The same /mcp endpoint serves the 2026-07-28 per-request protocol and automatically supports older 2025-era clients through stateless compatibility handling. There is no protocol mode to configure.
DevSpace is open to new sponsors.

Installation
DevSpace requires Node >=22.19 <27.
Install the DevSpace CLI:
npm install -g @waishnav/devspace
Then initialize DevSpace:
devspace init
Or run it without a global install:
npx @waishnav/devspace init
During setup, DevSpace asks for:
- where you will use it: ChatGPT, Coding Agents, or both
- which Coding Agents DevSpace may use
If you select ChatGPT, setup also asks which local project folders it may open
and for your public HTTPS base URL from Cloudflare Tunnel, ngrok, Pinggy,
Tailscale Funnel, or another reverse proxy. A Coding Agents-only setup asks
neither question: local commands use the current Git project, or the current
directory outside a repository.
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.
Run devspace serve when using ChatGPT. For Coding Agents, setup prints a
skills command and lets the Skills CLI handle installation.
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
[!NOTE]
Using DevSpace as an MCP connector isn't against OpenAI's Usage Policies — it's
a standard custom App/connector setup, and writing or running code isn't a
restricted use case. But your account is governed by your usage, not by
DevSpace. Don't point it at anything that would violate your provider's terms.
Used normally, you're fine. (Based on OpenAI's Usage Policies and Service Terms
as of June 2026.)
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:
- Start your tunnel.
- Run
devspace serve.
- Connect the MCP client to your public
/mcp URL.
- Approve the connection with the Owner password.
- Ask ChatGPT to open a project inside one of your allowed roots.
DevSpace supports Linux, macOS, and Windows environments with a Bash-compatible
shell.

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:
Install pnpm 11.25.0, the version pinned in package.json, with
npm install --global [email protected], then:
pnpm install --frozen-lockfile
pnpm dev:seed
pnpm dev
pnpm typecheck
pnpm test
pnpm build
pnpm start
dev:seed forks your normal DevSpace config and SQLite state into an ignored
checkout-local .devspace-dev/ directory so source builds and migrations do not
modify your normal installation. Use pnpm dev:reset to discard that QA state
and fork it again. See Development and Manual QA for
worktree switching, ChatGPT, and database-migration workflows.
DevSpace 是一个自托管的 MCP 服务器，让 ChatGPT（或其他支持 MCP 的客户端，如 Claude）能够读取、编辑、搜索和运行你本地真实项目中的代码，无需将任何内容上传到第三方。
