Metal MCP Server

Metal MCP Server is an MCP server that provides access to Apple Metal Framework documentation and code generation capabilities directly within AI assistants. It connects large language models to official Metal reference materials, best practices, and code generation routines. Designed for iOS, macOS, and graphics software engineers, the server allows developers to look up graphics pipeline APIs, compute shader patterns, and framework techniques without manually browsing Apple developer documentation. Users can query the server with natural language requests to retrieve focused technical documentation or immediately generate syntax-accurate code for tasks in Swift, Objective-C, or the Metal Shading Language. Additionally, it provides built-in reference resources covering framework fundamentals and performance optimization tips. By routing Metal-specific context directly into conversational AI environments, the server helps developers build low-level GPU rendering logic, compute pipelines, and custom shaders more efficiently.

How to install and configure Metal MCP Server

1. Clone or generate the server using the setup command: npx @modelcontextprotocol/create-server metal-mcp && cd metal-mcp && npm install && npm run build 2. Open your MCP client configuration file (such as claude_desktop_config.json). 3. Add the server under the mcpServers object using the built Node.js script: json { "mcpServers": { "metal": { "command": "node", "args": ["/path/to/metal-mcp/build/index.js"] } } } 4. Replace /path/to/metal-mcp/build/index.js with the absolute path to your compiled build output. 5. Save the configuration and restart your client to enable the server tools.

What you can do with Metal MCP Server

• Searching Metal Framework API references and usage guides using natural language queries directly within an AI chat interface. - Generating boilerplate GPU setup routines and command buffer workflows in Swift or Objective-C. - Writing custom vertex and fragment shaders using the code generation tool targeting the Metal Shading Language. - Referencing curated best practices to optimize GPU memory allocations and render pipeline state caching. - Accessing getting-started guides for initial device initialization and render pass configuration in graphics applications.

Part of MCP Servers

What is Metal MCP Server?

Metal MCP Server is a Model Context Protocol tool that lets AI assistants search Apple Metal Framework documentation and produce code examples. It gives coding assistants access to Metal resources, including setup guides, best practices, and multi-language code generation.

What tools does Metal MCP Server provide?

The server provides two main tools: search_metal_docs, which searches documentation and examples using natural language queries, and generate_metal_code, which generates framework code for tasks in Swift, Objective-C, or the Metal Shading Language.

How do I install Metal MCP Server?

You can set up the project by running npx @modelcontextprotocol/create-server metal-mcp, entering the metal-mcp directory, and executing npm install followed by npm run build. Afterward, configure your MCP client to execute the resulting build/index.js file using Node.

Which programming languages are supported for code generation?

The code generation tool explicitly supports three languages used across Apple graphics programming: Swift, Objective-C, and Metal, which refers to the Metal Shading Language used for vertex, fragment, and compute shaders.
