This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.
Run this in your terminal
claude mcp add --transport http waitloop https://waitloop.dev/api/mcp --header 'Authorization: your-value'Fill in the empty values before running it.
Or copy the settings yourself
Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

Common questions
Is Waitloop safe?
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
You need to fill in: Authorization
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed –, and the latest version (0.1.0) reached the registry 4 months ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
What can I use instead?

● waitloop
Waitlists your agent can launch.
A hosted waitlist page with referral ranking, created by one MCP tool call. Agent-first: MCP server + JSON CLI + REST API. The dashboard is optional.
waitloop.dev · Docs · llms.txt
Your agent builds the product. Waitloop starts the line:
> create a waitlist for my new CLI tool, dark page, orange accent● waitloop create_waitlist(...) ✓ live at https://waitloop.dev/w/ship-faster
Every waitlist gets a live hosted page, email capture, referral links (each signup gets a unique URL — when someone joins through it, the referrer moves up the list), stats, CSV export, webhooks, and an embeddable widget.
For agents
MCP (the primary interface):
claude mcp add --transport http waitloop https://waitloop.dev/api/mcp \--header "Authorization: Bearer wl_YOUR_KEY"
8 tools: create_waitlist, list_waitlists, update_waitlist, delete_waitlist, get_stats, list_signups, export_signups, add_signup.
CLI — every command outputs structured JSON, designed for LLMs and pipelines:
WAITLOOP_API_KEY=wl_YOUR_KEY npx waitloop-cli waitlists:create --name "Acme Robots"npx waitloop-cli stats acme-robots npx waitloop-cli export acme-robots --format csv
REST:
curl -X POST https://waitloop.dev/api/v1/waitlists \-H "Authorization: Bearer wl_YOUR_KEY" -H "Content-Type: application/json" \ -d '{"name": "Acme Robots"}'
Docs are agent-readable: llms.txt, and every docs page is raw markdown when you append .md.
Self-host
git clone https://github.com/zexiro/waitloopcd waitloop docker compose up -d
App on :3000, Postgres included, migrations run on boot. No license keys, no feature gates — everything in the cloud product works self-hosted. See self-hosting docs.
Development
pnpm installpnpm --dir apps/waitloop dev
No database needed for local dev — it falls back to embedded Postgres (PGlite) under .data/. Log in at /login; without RESEND_API_KEY, the magic link is printed to the server log.
