NetStone.MCP

NetStone.MCP

A Model Context Protocol (MCP) server for Final Fantasy XIV, built with .NET 8.

NetStone.MCP connects LLM clients (Claude Desktop, Cursor, ChatGPT, custom Discord bots, and autonomous agents) directly to FFXIV game data, including official Lodestone character and FC data, PaissaDB real-time housing availability, FFXIV Collect items & mounts, XIVAPI v2 recipes, and Chinese community lore/wiki databases.

Supports both Stdio (local process) and HTTP / SSE (remote server) transport modes.

{
  "mcpServers": {
    "netstone-mcp": {
      "command": "dotnet",
      "args": [
        "run",
        "--project",
        "C:\\path\\to\\NetStoneMCP\\src\\NetStoneMCP.csproj",
        "--no-build"
      ]
    }
  }
}

2. HTTP / SSE Mode (Cursor, VS Code, Remote Clients)

Launch NetStone.MCP with the SSE transport:

export TransportType=SSE
dotnet run --project src/NetStoneMCP.csproj

The MCP SSE endpoint will listen on:

cp .env.example .env
# Edit .env and supply OPENAI_API_KEY and DISCORD_BOT_KEY
docker compose up -d --build

Sample Applications

Ready-to-use sample clients are available under the sample/ directory:

1. Discord Bot (sample/NetStoneDiscordBot)

A Discord bot powered by OpenAI Function Calling and NetStoneMCP tools with channel context memory.

Interactive Option Clarification

When a user prompt is ambiguous or has multiple possible targets (e.g. asking "查巴哈" which could mean Bahamut world server, the Binding Coil raid, or primal lore), the AI invokes the ask_user_options tool to present interactive Discord buttons. The user simply clicks an option to proceed with the exact query without any guesswork.

Channel Memory & Extension

Maintains independent conversation context per Discord channel. When the memory is set to expire within 10 minutes, an interactive 延長記憶 10 分鐘 button appears, allowing users to extend session duration up to 1 hour.
