osu-mcp

osu-mcp is a Model Context Protocol (MCP) server that exposes the osu! API v2 as tools for Claude Desktop and other MCP clients. Ask Claude about your osu! profile, compare players, search beatmaps, browse rankings — all in natural language.

Quickstart

1. Install

uv tool install osu-mcp
# or
pip install osu-mcp

2. Get osu! API credentials

1. Go to https://osu.ppy.sh/home/account/edit
2. Scroll to OAuth, click New OAuth Application
3. Name: anything (e.g., "Claude Desktop"); Callback URL: leave blank.
4. Copy the Client ID and Client Secret.

3. Configure credentials

Option A — environment variables (recommended):

export OSU_CLIENT_ID=12345
export OSU_CLIENT_SECRET=your-client-secret

Option B — config file at ~/.config/osu-mcp/config.toml (Linux/Mac) or %APPDATA%\osu-mcp\config.toml (Windows):

client_id = 12345
client_secret = "your-client-secret"

4. Wire up Claude Desktop

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "osu": {
      "command": "uvx",
      "args": ["osu-mcp"],
      "env": {
        "OSU_CLIENT_ID": "12345",
        "OSU_CLIENT_SECRET": "your-client-secret"
      }
    }
  }
}

Restart Claude Desktop. You should see "osu" in the MCP servers list.
