Overview

AI-generated overview

Remote MCP server for the eighty gamified self-improvement app, letting an assistant read and write a real-life RPG character sheet.

What you can do
Browse, create, take and complete quests, including publishing authored quests to the catalog after review (create_quest, publish_quest, browse_quests, take_quest, complete_quest). Read the user's profile and character sheet, plus public profiles of other users (get_profile, view_public_profile). Manage skills, streaks, badges and leaderboards. Send and track challenges to friends and react to the social feed (send_challenge, list_challenges, get_challenge_details). Use pre-built prompts such as a personalized recommendation, alongside ambient resources.
When to use it
Useful when someone wants an assistant to plan their day as quests, coach them through real-world tasks, track character stats and streaks, or interact with friends through challenges and a social feed in the eighty app.
Requirements
A remote endpoint at mcp.80l.app over Streamable HTTP; no local package. OAuth 2.1 sign-in through a browser on first tool call, using Google, Apple, or email/password; new users get an account auto-provisioned. No API keys. An active eighty Premium subscription (sold via the iOS App Store) is needed for the challenge tools and leaderboard rows 11–50.
Before you install
The server reads and writes the same account as the iOS app, so quest creation, publishing, challenge sending and social reactions change real data and can notify other people's phones. Publishing a quest sends it into eighty's catalog after review. Some features require a paid Premium subscription. Sign-in creates an account if none exists.

Installation

In SourceWeft

  1. Open eighty in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.metlem80%2Feighty/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

README

eighty MCP — docs, prompts, and screenshots

[MCP] [Auth] [Status]

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 — browse_quests, create_quest, take_quest, complete_quest, get_profile, send_challenge, view_public_profile, 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 claude_desktop_config.json:

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:

bash
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:

ToolWhat it does
view_public_profileSame rich profile shape the iOS app shows on tap (level, stats, streaks, badges, completed quests, follower counts).
create_quest + publish_questAuthor a real quest from MCP that ships into eighty's catalog after review.
send_challenge (Premium)Real-time challenge to another user with a time limit — fires a push notification to their phone.
whats_next (prompt)One-shot personalized recommendation drawn from your profile, active quests, favorite skills, and today's daily quest.

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

OAuth 2.1 + PKCE + Dynamic Client Registration (RFC 7591). No API keys, no developer-portal signup. Any spec-compliant MCP client auto-discovers the OAuth endpoints from /.well-known/oauth-protected-resource and registers itself. Full wire-level flow in docs/auth.md.

Premium features

Most of the surface is free. Four tools (challenges) plus the top-50 leaderboard rows (rows 11–50) require an active eighty Premium subscription, which is sold through the iOS App Store. See docs/premium-features.md for what's gated and how to upgrade.
