Documentation Overview

BindAlias MCP

MCP bridge for the BindAlias Minecraft mod. Lets AI agents control Minecraft: query game state, take screenshots, execute aliases, manage recipes, read/write notes, and edit the per-save agent config.

Prerequisites

Minecraft with the BindAlias mod loaded
The mod's HTTP API enabled (listens on 127.0.0.1:25575 by default, with automatic port fallback)

Install in Zed

Add to your settings.json:

config.json

{
  "context_servers": {
    "bind-alias": {
      "command": {
        "path": "npx",
        "args": ["bind-alias-mcp"]
      }
    }
  }
}

Or with a local checkout:

config.json

{
  "context_servers": {
    "bind-alias": {
      "command": {
        "path": "node",
        "args": ["path/to/BindAlias-MCP/mcp_server.js"]
      }
    }
  }
}

Use --port N to match a non-default mod port:

json

"args": ["path/to/BindAlias-MCP/mcp_server.js", "--port", "25576"]

Zed spawns MCP servers at startup — reload Zed (zed-reload) after editing to pick up the new server.

Install via CLI

Terminal

npx bind-alias-mcp
# or globally
npm install -g bind-alias-mcp

The server speaks MCP on stdio. Point any MCP client at it.

The tool descriptions only cover the wire protocol — see the mod docs and the system prompt patch for the full alias reference.

Agent system prompt patch

The tool descriptions this server advertises only cover the wire protocol — the fixed facts the tools themselves must know. The gameplay knowledge (the full alias catalog, screens, variables, per-world cfg semantics) changes with the mod and your world, so it lives separately in a flexible patch:

PATCH TO YOUR PROJECT RULE.md — paste this into your agent's system prompt / project rules (e.g. Zed's AGENTS.md) to teach it how to drive the game.
