vHAL MCP Server

vHAL MCP Server is an MCP server that provides tools for exploring, searching, and implementing Android Vehicle Hardware Abstraction Layer (vHAL) documentation and source code. Built for Android Automotive OS (AAOS) engineers and embedded developers, it connects MCP-compatible clients to local and online Android automotive source references. The server enables users to discover vHAL properties, inspect hardware definitions across categories like HVAC and seating, and trace functional dependencies. It also assists in code creation by generating HAL definitions, Java APIs, unit tests, and build configurations for custom and standard properties. Additionally, the server validates property requests against Android 16 standards to prevent duplicate implementations, evaluates documentation source reliability with accessibility checks, and prepares formatted pull request messages complete with testing checklists and technical summaries.

How to install and configure vHAL MCP Server

Follow these steps to set up the vHAL MCP Server with Claude Desktop: 1. Ensure Python 3.12 or higher and uv are installed on your system. 2. Clone the repository locally: bash git clone https://github.com/feevlic/vhal-mcp-server.git cd vhal-mcp-server 3. Install dependencies in editable mode: bash pip install -e . 4. Find the absolute path to your uv binary using which uv. 5. Open your Claude Desktop configuration file (~/Library/Application Support/Claude/claude_desktop_config.json on macOS or %APPDATA%/Claude/claude_desktop_config.json on Windows). 6. Add vhal-mcp-server under the mcpServers section using the full paths to uv and the cloned repository directory: json { "mcpServers": { "vhal-mcp-server": { "command": "/path/to/uv", "args": ["run", "--directory", "/path/to/vhal-mcp-server", "python", "main.py"], "env": { "PYTHONPATH": "/path/to/vhal-mcp-server" } } } } 7. Restart Claude Desktop and grant permission when prompted.

What you can do with vHAL MCP Server

• Search Android Automotive OS source code for existing vHAL property identifiers, access modes, and data types. - Generate complete implementation code, including HAL files, Java bindings, and tests, for custom automotive properties. - Inspect multi-zone HVAC dependencies and receive structured implementation guidance for cabin climate control systems. - Validate new property proposals against Android 16 standards to determine if existing properties can be used instead. - Produce comprehensive pull request descriptions with change summaries and review checklists for automotive HAL contributions.
