What the publisher says

From the eighty repository's README, as published. We do not edit it. Read it on GitHub

eighty MCP — docs, prompts, and screenshots

A public Model Context Protocol server that lets any MCP-compatible client — Claude Desktop, Claude.ai Connectors, Cursor, ChatGPT Apps, MCP Inspector — read and write a real-life RPG character sheet.

The server is live at https://mcp.80l.app. This repo is the documentation, example prompts, and reference screenshots — not the server source.

What is this

eighty is a gamified self-improvement iOS app: real-world quests, character stats, skill trees, badges, streaks, leaderboards, social challenges. The MCP server exposes the same 35 actions the iOS app uses — browsequests, createquest, takequest, completequest, getprofile, sendchallenge, viewpublicprofile, the whole catalog — so an LLM client can drive the experience: plan your day as quests, coach you through them, send challenges to friends, react to your social feed, level up your character.

It's the same backend the iOS app talks to. No fork. Your MCP session and your iOS app are two views over one account.

Quickstart

Add to your claudedesktopconfig.json:

{
  "mcpServers": {
    "eighty": {
      "url": "https://mcp.80l.app"
    }
  }
}

Restart Claude Desktop. On first tool call, OAuth opens in your browser — sign in with Google, Apple, or email/password. (New users get an account auto-provisioned at sign-in.) You're now connected.

Full setup for other clients (Cursor, Claude.ai web Connectors, MCP Inspector, ChatGPT Apps) is in docs/auth.md.

Try it without installing anything

Inspector — Anthropic's reference MCP client — runs locally with no setup:

npx @modelcontextprotocol/inspector

In the browser: set Transport Type to Streamable HTTP, URL to https://mcp.80l.app, Connection Type to Via Proxy, click Connect. Authorize via the OAuth popup. The full tool catalog loads in the sidebar.

Tools

35 tools across 7 categories — quests, quest creation, skills, profile, social, challenges, leaderboard. Plus 4 ambient resources and 3 pre-built prompts. Full reference in docs/tools-reference.md.

A few signature examples:

Hand-picked example prompts (copy-paste into your client) are in prompts/.

How it works

client → mcp.80l.app (OAuth 2.1) → same backend handlers the iOS app uses → persistence

The MCP server is a thin authorization shell — every tool delegates to the same handler the iOS app calls. One source of truth for business rules (quest caps, premium gating, social-graph privacy, idempotency). See docs/architecture.md.

Authentication

Shortened. The full README is on GitHub.
