dothub

The agent setup hub. Publish your whole coding-agent setup. Browse a feed of other people's. Pull one in with a single approval.

dothub is one FastAPI app that does two things: a web feed you read in the browser, and a remote MCP server your coding agent talks to. Your agent publishes your setup. You browse and install other people's. No upload forms, no export scripts.

It started for Claude Code, but it records provenance for any coding agent (Codex, Cursor, Windsurf, Gemini CLI, and more).

✨ Why dothub

• 🤖 Agent-native publishing. You tell your agent "publish my setup." It gathers your CLAUDE.md, skills, commands, agents, hooks, and MCP config. No form, no manual export.

• 🔒 Private by default. When your agent publishes, the setup lands private. It is hidden from the feed, search, and every other user. Only you can see it. Nothing goes public until you explicitly click Publish to everyone.

• 🛡️ Encrypted at rest. Your setup files are encrypted on the server's disk. They stay invisible to everyone but you until you publish.

• 📖 Effects manifest, always. Before you install anyone's setup, dothub shows you exactly what it does: every hook command verbatim, the MCP servers and plugins it adds, a runs_code flag, and any secret-looking strings it caught. You review, then you approve.

• 🏠 Self-hostable on one box. SQLite and local disk by default. Runs with nothing but Python locally, and deploys to a single small server with automatic HTTPS.

🚀 Quick start (local, zero infra)

git clone https://github.com/catancs/dothub.git
cd dothub
pip install -r requirements.txt

DATABASE_URL='sqlite+pysqlite:///./dothub.db' \
STORAGE_DIR='./dev-bundles' \
SESSION_SECRET='dev-secret' \
uvicorn app.main:app --reload

Then open:

• 🌐 Feed: http://localhost:8000/

• 🔌 MCP server: http://localhost:8000/mcp/

• 💚 Health: http://localhost:8000/healthz

🤝 Add it to Claude Code

Sign up at http://localhost:8000/signup and mint an API key on your account page (it starts with dh_ and is shown once). Then:

claude mcp add --transport http dothub http://localhost:8000/mcp/ \
  --header "Authorization: Bearer dh_your_key_here"

Once it's live, swap in https://dothub.nl/mcp/.

📤 Publishing your setup

The server never reads your disk. Your agent does. In a Claude Code session, say something like "publish my Claude Code setup to dothub as my-flow." The agent reads your ~/.claude/ (and the project .claude/ if you want), builds a {path: content} map, shows you a preview, and publishes when you approve.

Never upload secrets. The effects manifest flags patterns like sk-..., AKIA..., and PRIVATE KEY blocks under secret_flags, but you are responsible for leaving tokens and .env files out. Don't publish ~/.claude.json (it holds private state), memory files, or conversation history.

What happens to a setup you publish

1. Your agent sends it to dothub. It is encrypted and stored.

2. It lands private. Hidden from the feed and from your public profile. Only you can preview or install it.

3. You review it on its page. When you are ready, you click Publish to everyone.

4. It joins the public feed. Others can preview the effects and install it.

📥 Installing someone else's setup

Always preview first. In a Claude Code session: "preview their-slug" to see the effects manifest, review it, then "install their-slug." The agent writes the files to your ~/.claude/ (or project .claude/) only after you approve.

Installing code that runs on your machine (hooks, MCP servers, plugins) is your responsibility. Read the manifest before you say yes.

🧪 Tests

pytest -v          # in-memory SQLite + mocked S3, no infra needed

🚢 Deploy

The default production deploy runs the same SQLite + local-disk config on a single AWS EC2 box, with Caddy providing automatic HTTPS. See deploy/DEPLOY.md for the full runbook.

S3 and Postgres are still supported if you ever outgrow one box. Set the values from .env.example and the app switches backends with no code change.
