Remote servers need no local install. Pick your client, then copy the config or install in one click.

Cursor plugin
This repo is a Cursor plugin. Install it from the Cursor Marketplace (after it’s published) or add the repo in Cursor to use the demo.st MCP server.
Getting your MCP token
Authenticated tools (reserve subdomain, upload zip, clear, release) require a Bearer token:
- Sign in at https://demo.st (create an account if needed).
- Open https://demo.st/api/mcp/token or the MCP page and copy the token.
- Set it as an environment variable:
- Windows (PowerShell):
$env:DEMO_ST_MCP_TOKEN = "your-token-here" - macOS / Linux:
export DEMO_ST_MCP_TOKEN="your-token-here" - Or add to your shell profile (
.bashrc,.zshrc) so Cursor picks it up.
- Windows (PowerShell):
- Restart Cursor (or reload the window). The Agent can then use demo.st tools.

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.
