Oshaberi Dungeon

Talk your way through adventure

Version 1.32 — Updated April 20, 2026

What is Oshaberi Dungeon?

Oshaberi Dungeon is an adventure game built on the Model Context Protocol (MCP). Play directly inside Claude — no separate app needed. Your AI companion narrates the journey while the server manages game rules, creating a consistent and replayable experience.

Unlike chat-based AI games, Oshaberi Dungeon uses MCP tools to create a layered exploration system. The AI does not make up the rules — the server enforces them. This means the same dungeon plays consistently, different players discover different things, and every playthrough tells a unique story.

Features

Layered exploration

Each room has multiple layers. Examine objects closely, look from different angles, and uncover hidden secrets.

Persistent progress

Your position, inventory, and discoveries are saved across sessions.

Adventure memories

Save your favorite moments from your journey.

AI companion

The AI brings the world to life with engaging narration while the server enforces the rules.

Multilingual

Ask the AI to respond in any language. It just works.

Creative freedom

Say anything. Try anything. The server decides what works.

Getting Started

In Claude.ai, go to Settings > Connectors > Add Custom Connector
Enter a name (e.g. Oshaberi Dungeon) and the URL: https://dungeon.oshaberigames.com/mcp, then click Add
Click the Connect button on the added connector
Complete OAuth authentication (enter your email and verification code)
In a new chat, say: Let's play Oshaberi Dungeon!

Authentication

Oshaberi Dungeon uses OAuth 2.1 with PKCE. You will create a game account during the OAuth flow. No personal information is required beyond an email address for authentication.

Examples

Example 1: Ask your AI companion for shopping advice

You say

"I have 100 gold. What should I buy?"

What happens

Your AI companion considers your budget, compares the available weapons and armor, and suggests the best loadout for your adventure. Like having a knowledgeable friend at the shop — an experience only possible in an AI-powered game.

Example 2: Layered exploration — discover hidden secrets

You say

"Let's look at the chest from a different angle"

What happens

The server reveals previously hidden elements — a keyhole on the back of the chest. You find a flint, light a torch, discover a rusty key in the newly lit area, and use it on the hidden keyhole to unlock the chest. Each discovery leads to the next, rewarding curiosity and creative thinking.

Example 3: Creative problem-solving with AI narration

You say

"Flying knee kick!" (at a heavy iron door)

What happens

The server determines the kick fails — the rusty door doesn't budge and your foot hurts. The AI narrates the failed attempt with humor. You try "If pushing doesn't work, try pulling!" and the door creaks open. Creative problem-solving is rewarded.
