# How do I install Neonjelly MCP in Cursor, Claude, or ChatGPT?

One click in Cursor, Claude, VS Code, ChatGPT, or Windsurf. Trial starts on click.

Fast path: [/start](https://www.neonjelly.io/start.md). One button mints a trial, hits the catalog, then **Open in Cursor**. That is three actions.

The site buttons call `POST https://mcp.neonjelly.io/v1/trial`, then hand the client a **connect URL**. Auth is in the path. You do not paste `nj_`.

Listed: [Official MCP Registry](https://registry.modelcontextprotocol.io/?search=neonjelly) (`io.neonjelly/mcp`), [Smithery](https://smithery.ai/servers/ops-qunq/neonjelly), public connect repo [germanas/neonjelly-mcp-public](https://github.com/germanas/neonjelly-mcp-public).

Same device (browser install id) or live IP → same trial (secret is not shown again). Browser keeps the connect URL in `localStorage` as `nj_trial_v2` and a device id as `nj_install_v1`.

## Cursor

Opens `cursor://anysphere.cursor-deeplink/mcp/install` with `{ url: connectUrl }`. Accept the prompt.

## Claude.ai / Claude Desktop

Opens Claude’s add-connector URL with name Neonjelly and the connect URL. Click **Add**.

## VS Code

`vscode:mcp/install` with `type: http` and the connect URL. Accept.

## Claude Code

Copies:

```bash
claude mcp add --scope user --transport http neonjelly https://mcp.neonjelly.io/c/njc_…/mcp
```

Run in a terminal, not inside a Claude session.

## ChatGPT

Copies the connect URL and opens Settings → Connectors. Developer mode → Create → name Neonjelly → auth **none** → paste URL.

## Windsurf

Copies the connect URL. Cascade → Manage MCPs → Add Server. Or `~/.codeium/windsurf/mcp_config.json`:

```json
{
  "mcpServers": {
    "neonjelly": { "serverUrl": "https://mcp.neonjelly.io/c/njc_…/mcp" }
  }
}
```

## After install

Ask: “What's my quota?” (MCP `whoami` — plan, used today, remaining, expiry; not metered). Then: “Call list_playbooks, then diligence_pack on gruntstyle.com.”

Do not scrape. Do not probe. Missing store stays `not_found`. Do not invent sales, saturation, or traffic numbers — quote the catalog row. Signals (ads and daily units) are paid only. Trial keys get 403 on create_signal and signal reads. Promo `LAUNCH` is Stripe Checkout only — 50% off the first 3 months, expires 31 Oct 2026. Not MCP metadata.
