poe-buildmcp 0.1.1

MCP server for Path of Exile game data

PoeMCP

An MCP server that gives any LLM access to Path of Exile game data — gems, unique items, passive tree nodes, item modifiers, maps, scarabs, live pricing, and Path of Building build parsing.

Data is fetched at runtime from poedb.tw, poe.ninja, and poewiki.net. No API key required.

Installation

Requirements

• Claude Desktop, Claude Code (CLI), or any other MCP-compatible client
• Internet access (all data is fetched at runtime)

Quick install (recommended) — no clone, no manual setup

PoeMCP is published to PyPI as poe-buildmcp, so an ephemeral runner like uvx can fetch and run it on demand — nothing to clone or keep updated. Add this to your MCP client config:

{
  "mcpServers": {
    "poemcp": {
      "command": "uvx",
      "args": ["--from", "poe-buildmcp", "poemcp"]
    }
  }
}

• Claude Desktop config location: macOS ~/Library/Application Support/Claude/claude_desktop_config.json · Windows %APPDATA%\Claude\claude_desktop_config.json
• Claude Code (CLI): add the same block to your project's .mcp.json — see mcp.json.example
• Requires uv installed (which provides uvx); no separate Python install needed, uvx manages its own interpreter.

💡 Not sure how to configure Claude? Ask Claude directly: "Add an MCP server called PoeMCP to my config, using command uvx and args [\"--from\", \"poe-buildmcp\", \"poemcp\"]." Claude will walk you through finding the config file and adding the correct JSON block for your OS.

Manual install (for development / hacking on the source)

⚠️ Python 3.10+ is required for this path. Download from python.org if you don't have it.

git clone https://github.com/shalayiding/POEMCP.git
cd POEMCP
pip install -e .

Then point your MCP config at the cloned copy instead of uvx:

macOS / Linux:

{
  "mcpServers": {
    "poemcp": {
      "command": "python",
      "args": ["/path/to/PoeMCP/server.py"]
    }
  }
}

Windows:

{
  "mcpServers": {
    "poemcp": {
      "command": "python",
      "args": ["C:\\path\\to\\PoeMCP\\server.py"]
    }
  }
}
