Install

In your terminal, with SkillFoxx CLI

npx skillfoxx add mcp/earlypass

Detects the agents on your machine, checks the risk and pins the version.

Other ways to install

Assembled automatically, review before installing.

Run in a terminal

Checked against the repository on Sep 26, 2026, commit 9a26007.

Text for your agent

On your server, run curl -O https://www.earlypass.app/docker-compose.yml, set DASHBOARD_JWT_SECRET and bring it up with docker compose up -d, then connect your MCP client to https://your-domain/mcp via OAuth or an Authorization Bearer ep_acc_your_key header.

Other ways from the author
curl -O https://www.earlypass.app/docker-compose.yml
export DASHBOARD_JWT_SECRET=$(openssl rand -hex 32)
docker compose up -d

The main self-hosted install path; needs your own Postgres and Redis, or the ones started by docker-compose.

This is third-party code. Review the repository files before installing.

What it does

EarlyPass is a standalone product: an embeddable waitlist widget with referral mechanics, a leaderboard and analytics, deployed self-hosted via Docker Compose, Kubernetes or a single container. Beyond the web widget and dashboard, the service runs its own MCP server at /mcp that lets an agent create and edit campaigns, check signup and referral stats, invite the top leaderboard entries with invite emails, export signups as JSON or CSV, and manage webhooks. MCP connections use OAuth 2.1 with automatic discovery for clients like Claude Desktop or MCP Inspector, or an account API key as a Bearer token.

Who it is for. For founders and marketers launching a viral product waitlist who want to manage campaigns through an agent.

Good fit when

  • You need a self-hosted waitlist widget with referrals and a leaderboard on your own site
  • You want an agent to create campaigns, invite top referrers and export signups on its own
  • You need to programmatically grant access to top signups by email once a threshold is reached

Not a fit when

  • You do not want a separate self-hosted service: hosted waitlist SaaS tools already exist
  • The project is work in progress and, per the author's own warning, not production ready
  • You need a tool tied to the Russian stack: this service has no connection to Russian services

Example request

Show the launch campaign stats and invite the top 20 signups by referral count

Limitations

The author explicitly warns the project is under active development, APIs may change, parts are incomplete, and it is not production ready. It needs your own Postgres and Redis, or the full Docker Compose stack. It is Business Source Licensed, not perpetually open. MCP access needs either OAuth 2.1 or an account API key.

How to disable. Stop the stack with docker compose down and remove the MCP server from your client settings.

README in short

The English README describes an open self-hosted waitlist widget with a quick start via Docker Compose, a single container or a Helm chart. A dedicated MCP Server section lists 12 tools for campaigns, signups, export, invites and webhooks, explains OAuth 2.1 or API-key connection, and gives the discovery and token endpoints. It covers invite tokens with verification and redemption through the product's own backend, and detailed local development instructions using mise, kind and tilt.

FAQ

Can I only manage my own campaigns?

Yes, every MCP tool requires account-level authentication and enforces campaign ownership.

How does the agent invite signups without a password?

invite_signups sends emails with a personalized link and token that your product backend can verify and redeem via its own API.
