MCP support
The host0 plugin bundles a skill for publishing and an MCP server for managing live projects, including sharing, versions, analytics and shared data.
Configuration
Remote servers need no local install. Pick your client, then copy the config or install in one click.

Servers that need sign-in will prompt on first connect.

Details
From the project READMEhost0 skills
host0 hosts whatever your agent creates — HTML pages, sites, apps with a shared database, Markdown, PDFs — at a link you can share. This repo holds the host0 skill: it teaches any coding agent to publish a file or folder to a live https://<slug>.host0.app URL in one step.
Install
npx skills add host0-ai/skills
Works with Claude Code, Cursor, Codex, Gemini CLI, GitHub Copilot, Windsurf, Cline and every other agent the skills CLI supports. Add -g to install it for all your projects. npx skills add https://host0.ai installs the same skill straight from host0.
No Node? One curl command installs the same files into your agent's skills folder. It uses no sudo and never overwrites a copy you changed without --force:
curl -fsSL https://host0.ai/install.sh | bash
As a plugin: the skill and the MCP server in one install
The skill publishes; the MCP server manages what's live (sharing, versions, analytics, shared data). The plugin brings both.
Claude Code:
/plugin install host0 --marketplace host0-ai/skills
Codex:
codex plugin marketplace add host0-ai/skills
Then install host0 from the plugin directory. Cursor reads the same plugin.json and mcp.json: add this repository as a plugin from Cursor's plugin settings.
Use it
Ask your agent:
- "Deploy this to host0"
- "Give me a link to this PDF"
- "Build a team todo list with a shared database and publish it"
- "Roll back the last deploy"
The first publish starts a device login: the agent shows a link and a short code, you approve it on host0.ai in your own browser, and the agent gets an API key. Nothing personal is typed into the chat.
What you get
- Private by default. Only you and people you invite by email can open an app. Open it to anyone with the link, or make it public on the web, when you want to.
- A shared database with no server code. Declare record collections in an
h0.jsonand the app's frontend reads and writes them on its own origin. - Versions and one-click restore, cookieless analytics, and a readable URL whenever you rename it.
- Any file or folder: a static site, a single HTML page, a PDF, images, video, Markdown.
There is a free plan. Docs: host0.ai/docs.

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
