Arm MCP Server

Added to Onei Sep 13, 2026

Apache-2.0

Summary

Arm's official MCP server for porting and tuning software on Arm — semantic docs search, codebase migration scanning, container architecture checks and LLVM-MCA assembly analysis.

Features

Semantic search over Arm documentation, learning paths and intrinsics
Codebase migration scanning for C++, Python, Go, JavaScript and Java
Docker image architecture inspection for arm64 support
Assembly performance analysis via LLVM-MCA
Runs as a stdio Docker container in any MCP client

Installation

Set up this MCP server in your favorite AI agent — copy a ready-made configuration below.

Any MCP-compatible agent

Most agents (Claude, Cursor, Windsurf, VS Code, and more) read a standard mcpServers configuration.

Open your agent's MCP configuration file.
Merge the snippet below into it.
Restart the agent — the "Arm MCP Server" tools will be available.

{
  "mcpServers": {
    "arm-mcp-server": {
      "command": "docker",
      "args": [
        "run",
        "--rm",
        "-i",
        "--pull=always",
        "-v",
        "/path/to/your/workspace:/workspace",
        "armlimited/arm-mcp"
      ]
    }
  }
}

Claude Code

Add the server with a single CLI command.

claude mcp add arm-mcp-server -- docker run --rm -i --pull=always -v /path/to/your/workspace:/workspace armlimited/arm-mcp

Claude Desktop

Add the server to claude_desktop_config.json (Settings → Developer → Edit Config).

{
  "mcpServers": {
    "arm-mcp-server": {
      "command": "docker",
      "args": [
        "run",
        "--rm",
        "-i",
        "--pull=always",
        "-v",
        "/path/to/your/workspace:/workspace",
        "armlimited/arm-mcp"
      ]
    }
  }
}

Cursor

{
  "command": "docker",
  "args": [
    "run",
    "--rm",
    "-i",
    "--pull=always",
    "-v",
    "/path/to/your/workspace:/workspace",
    "armlimited/arm-mcp"
  ]
}

Description

Arm MCP Server is the chip designer's own Model Context Protocol server for teams moving software onto Arm-based hardware, whether that is Graviton instances in the cloud, Apple silicon on the desktop, or an Arm server fleet on-premises.

Migration work is mostly archaeology: finding the x86 intrinsic buried in a hot loop, the dependency that ships amd64-only wheels, the base image with no arm64 tag. This server gives a coding agent the tools to do that search itself instead of asking an engineer to grep for it.

What it exposes

Knowledge base search — semantic search across Arm's documentation, learning paths, intrinsics reference and software compatibility data, so the agent answers from Arm's own material rather than from memory.
Code migration analysis — scans a codebase for Arm compatibility issues across C++, Python, Go, JavaScript and Java.
Container architecture inspection — checks whether a Docker image actually publishes an arm64 variant before a migration plan assumes it does.
Assembly performance analysis — runs LLVM-MCA over assembly to model throughput and port pressure on Arm cores.

Running it

The server ships as the armlimited/arm-mcp Docker image and speaks stdio, so any MCP client that can launch a container can use it. Mount the workspace you want analysed as a volume; published client configurations cover Claude Code, GitHub Copilot in VS Code, AWS Kiro CLI, Gemini CLI and TOML-based clients. The repository is Apache-2.0 licensed.
