Overview

AI-generated overview

Local MCP bridge to the BindAlias Minecraft mod, letting an assistant inspect game state, take screenshots, run aliases and edit per-save config and notes.

What you can do
  • Read full game state: screen, world, player position, health, inventory, effects, nearby players and queued chat/mod messages
  • Capture screenshots returned as base64 PNG
  • Run chains of aliases and define new aliases at runtime
  • Read and overwrite the per-save agent config, then reload it
  • Read and write plain-named files in the per-save agent directory
  • List unlocked recipes, as a diff or by query, while a recipe-book screen is open
When to use it
Useful when you play Minecraft with the BindAlias mod and want an AI agent to observe the world, act through aliases, and keep per-save notes or agent settings. It is aimed at singleplayer worlds where the mod's local HTTP API is enabled.
Requirements
Runs as a local Node.js process (npx bind-alias-mcp or a local checkout). Needs Minecraft with the BindAlias mod loaded and the mod's HTTP API enabled, listening on 127.0.0.1:25575 by default; use --port to match a different port. Config and notes tools require being in a singleplayer world.
Before you install
The assistant can act in the game by running aliases and can overwrite the per-save agent config and write files in the per-save agent directory, so changes persist in the save. It talks to a local mod HTTP API on 127.0.0.1, so keep that endpoint bound to localhost. Tool descriptions cover only the wire protocol; gameplay knowledge comes from a separate prompt patch you paste into your agent rules.

Installation

In SourceWeft

  1. Open Bind Alias Plus Mcp in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

README

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:

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

Or with a local checkout:

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

bash
npx bind-alias-mcp# or globallynpm install -g bind-alias-mcp

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

Tools

ToolWhat it does
getFullStateFull game state snapshot — screen, world, dimension, player pos/rot, health, hotbar, inventory, effects, nearby players, plus drained chat/mod/sound/recipe messages
getScreenshotTake a screenshot, return as base64 PNG with the standard state envelope
runAliasExecute a chain of aliases. Optional nap (client ticks) defers the response while the game keeps running.
defineAliasDefine a new alias at runtime (requires being in a world).
readCFGRead the per-save agent config (saves/<save>/bind-alias/agent.cfg). Requires being in a singleplayer world.
writeCFGOverwrite the per-save agent config and reload. Requires being in a singleplayer world.
readNotesRead a file from the per-save agent directory (saves/<save>/bind-alias/). Plain filenames only, no paths.
writeNotesWrite a file to the per-save agent directory. Plain filenames only, no paths.
listRecipesList unlocked recipes (diff or by query). Only works with a recipe-book screen open (inventory, crafting table, furnace, …).

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.
