Write OSRS Bot Scripts with AI: PowBot Mobile MCP Server

Writing OSRS bot scripts used to mean spending hours reading API documentation, trial-and-error debugging, and piecing together code samples from forum posts. With the PowBot Mobile Docs MCP Server, you can now use AI coding assistants like Claude Code, Cursor, or Droid to write PowBot Mobile scripts with direct access to the entire SDK — 5,200+ API reference pages, guides, tutorials, and code examples, searchable on demand.

This post walks through what MCP is, how to set it up, and what it actually looks like to write OSRS bot scripts with AI assistance.

What Is MCP and Why Does It Matter for Script Writing?

MCP (Model Context Protocol) is a standard that lets AI coding assistants connect to external tools and data sources. Think of it like giving your AI assistant a direct line to the PowBot SDK documentation.

Without MCP, writing scripts with AI means copy-pasting documentation into chat, hoping the model remembers it, and repeating the process every session. The AI has a vague understanding of PowBot but no reliable access to the actual API.

With MCP connected, the AI can:

• Search the entire PowBot Mobile SDK documentation on demand
• Look up specific classes, methods, and properties as it writes code
• Access code examples and scripting patterns
• Stay current — the documentation is synced from the mobile client source

The difference is substantial. Instead of an AI that sort of knows PowBot, you get one with the entire SDK reference available at all times. It can look up the correct method signature for Condition.wait(), find the right way to use EventFlows for inventory tracking, or generate a complete script template with proper structure — all without you feeding it documentation manually.

Setting Up the PowBot Mobile MCP Server

The MCP server lives at https://mobile-mcp.powbot.org/mcp. Setup takes about 30 seconds depending on your tool.

Claude Code (CLI)

Add to your MCP settings (~/.claude/settings.json or project .claude/settings.json):

{
  "mcpServers": {
    "powbot-docs": {
      "type": "http",
      "url": "https://mobile-mcp.powbot.org/mcp"
    }
  }
}

Droid

droid mcp add powbot-docs https://mobile-mcp.powbot.org/mcp --type http

Start a new session and you're ready to go.

Cursor

Open Settings → Cursor Settings → MCP, click "Add new global MCP server", and add:

{
  "powbot-docs": {
    "url": "https://mobile-mcp.powbot.org/mcp"
  }
}

Or edit ~/.cursor/mcp.json directly.

Claude Desktop

Add to your claude_desktop_config.json:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "powbot-docs": {
      "url": "https://mobile-mcp.powbot.org/mcp"
    }
  }
}

IntelliJ IDEA

Open Settings → Tools → AI Assistant → Model Context Protocol, click "+" and enter:

• Name: powbot-docs
• URL: https://mobile-mcp.powbot.org/mcp
• Type: HTTP

Writing Scripts with AI: What It Actually Looks Like

Once the MCP server is connected, you can ask your AI assistant to write PowBot Mobile scripts in natural language. Here are some real queries that produce working results:

• "Create a woodcutting script that banks oak logs at the nearest bank"
• "How do I use Condition.wait() properly?"
• "Show me EventFlows examples for inventory tracking"
• "What's the correct way to use PaintBuilder?"
• "How do I interact with NPCs?"
• "Build a fishing script for Barbarian Village with food support"

The AI searches the SDK docs in real time, finds the relevant API methods, and generates Kotlin/Java code that follows PowBot's scripting patterns. It knows about the tree script architecture, the correct way to handle game state, and the proper lifecycle methods.

We've had good results one-shotting simple scripts with Claude — asking for a complete script and getting working code back on the first try. More complex scripts benefit from iterating: generate a base, test it, and ask the AI to fix issues or add features with the full SDK context still available.

Which AI Tool Works Best?

We recommend Claude-based tools — Claude Code, Cursor with Claude as the model, or Droid. Claude excels at understanding the SDK patterns and generating idiomatic PowBot scripts. That said, the MCP server works with any tool that supports the Model Context Protocol.

MCP Server Features

The server provides more than just raw documentation lookup:

• Semantic search — find relevant docs even with vague queries. Asking "how do I make my character eat food when health is low" returns the right API methods even though those exact words don't appear in the docs.
• Full API reference — every class, method, and property in the PowBot Mobile SDK is documented and searchable. That's 5,200+ pages of reference material.
• Script scaffolding — the AI can generate complete script templates with proper structure, lifecycle methods, and configuration.
• Always up to date — the documentation is synced from the mobile client source code, so the AI always has access to the latest API.

PowBot Desktop Has One Too

If you're writing scripts for PowBot Desktop (Lua scripting), there's a separate MCP server at https://desktop-mcp.powbot.org/mcp. The setup is identical — just swap the URL. Desktop scripts use Lua instead of Kotlin/Java, but the same AI workflow applies: describe what you want, and the AI writes it with full API context.

Getting Started

If you're new to PowBot:

1. Create an account at powbot.org — join the PowBot Discord and use /register to get a token.
2. Set up your AI tool with the MCP server URL above.
3. Start simple — ask for a basic script like "write a script that chops trees and banks logs" and iterate from there.
4. Browse existing scripts at the script store to see what's already available before writing your own.

The MCP server is free to use for all PowBot users. This is the first step in our push to make AI a first-class tool for PowBot script development — more is coming.
