Hostilo

Hostilo MCP server

Publish and update websites from your AI chat. Hostilo is hosting for AI-generated websites: ask Claude, ChatGPT, Gemini, Cursor or any MCP client to create a site, publish a single page or a whole multi-file project, start from a ready-made template, check visitor stats or roll back a change. It goes live at https:// .hostilo.page in seconds.

This is a remote MCP server. There is nothing to install or run: connect your client to the URL below and sign in to Hostilo.

https://hostilo.app/mcp

• Transport: Streamable HTTP
• Authentication: OAuth 2.1 with PKCE (S256) and dynamic client registration. No API key.
• Docs: https://hostilo.app/agents#mcp
• Step-by-step guide: https://hostilo.app/blog/publish-website-from-claude-mcp-connector
• Server version: 1.7.0
• Claude connector directory: https://claude.ai/directory/connectors/hostilo-app

Connect

Claude (claude.ai, desktop, mobile): Hostilo is listed in Claude's connector directory. Open Hostilo in the directory, click Connect and sign in. You can also find it in Settings → Connectors → Browse connectors, or add it by hand: Add custom connector → paste https://hostilo.app/mcp.

Cursor and other agent tools: this repository is also an Agent Plugin: plugin.json, mcp.json with the server, the publish-website skill and a Cursor rule in rules/hostilo.mdc. In Cursor you can also add the server directly in Settings → MCP with the URL above.

ChatGPT, Perplexity and other apps: look for custom connectors or MCP servers in the app's settings and add the same URL. Which plans can add custom connectors is up to each app.

Gemini CLI (extension with the server and usage notes for Gemini):

gemini extensions install https://github.com/hostilo/hostilo-mcp

Then run /mcp auth hostilo in Gemini CLI and sign in to Hostilo in the browser. Without the extension: gemini mcp add --transport http hostilo https://hostilo.app/mcp.

Gemini on the web: where Google offers custom apps for your account, open Gemini settings, Connected apps, add a custom app and paste the same URL.

Claude Code:

claude mcp add --transport http hostilo https://hostilo.app/mcp

One-click install for Cursor and VS Code: buttons at https://hostilo.app/agents#install

Cursor, Windsurf, VS Code and other clients (`mcp.json`):

{

"mcpServers": { "hostilo": { "url": "https://hostilo.app/mcp" } } }

Tools

Example prompts

• "Build a one-page site for my bakery and publish it on Hostilo as sweet-crumbs."
• "Make a landing page with separate CSS and JS files and a logo, and publish it on Hostilo as launch-day."
• "Create a Hostilo site called sparks-electric from the local business template, electrician version. Name: Sparks Electric, phone +1 555 010 0200."
• "Import this ZIP into my site portfolio, but show me what will change first."
• "How many visitors did sweet-crumbs get this week, and where did they come from?"
• "Undo the last change on my landing page."

Limits

• Single page: up to 5 MB of HTML.
• Multi-file publish: up to 300 files; ZIP up to 20 MB, one file up to 10 MB; MCP request body up to 28 MB.
• 60 tool calls per minute per account.

Safety

• You choose permissions on a consent screen; the assistant sees only the tools you allowed.
• There is no tool that deletes a site, and every publish keeps the previous version.
• import_zip removes existing files only when asked (clear_assets), and its dry run changes nothing.
• Site HTML is returned as data, never as instructions.
• Every published page goes through a phishing scanner.
• Connections can be revoked at any time in the Hostilo dashboard (API & tools → AI connections).

Plans

• Free: 5 sites on name.hostilo.page with HTTPS, a working contact form (50 messages a month) and 7-day visitor stats. No credit card.
• PRO ($29/year, net): custom domains, 20 sites and 1 GB, no "Powered by Hostilo" badge, unlimited form messages, form webhooks and CSV export, password-protected pages, and stats for 30, 90 or 365 days with countries, sources and devices.
