How to Set Up and Use AOSP Explorer
Android Source Explorer MCP is a server that gives AI assistants offline access to AOSP (Android Open Source Project) internals and Jetpack library source code. It uses a dual-engine architecture — Tree-sitter for sub-10ms structural parsing and an optional Language Server Protocol (LSP) engine for cross-file definition resolution and reference finding. Android developers use it to let Claude or other AI clients navigate framework classes, understand Jetpack Compose internals, and answer deep questions about Android platform APIs without leaving their development environment.
Prerequisites
- Python 3.11+ or uv package manager installed
- Git installed for cloning the package
- An MCP-compatible client such as Claude Desktop, Cursor, or VS Code with Copilot
- Sufficient disk space for Android source files (several GB depending on API level and Jetpack modules selected)
- Internet connection for the initial sync of AOSP and AndroidX sources
Install android-source-explorer via uv
Install the package directly from GitHub using uv tool install. This is the recommended approach as it manages the Python environment automatically.
uv tool install git+https://github.com/mrmike/android-source-explorer-mcpSync Android source files
Download AOSP source for your target API level and the Jetpack AndroidX libraries you need. This step fetches the actual source code that the MCP server will index and serve.
android-source-explorer sync --api-level 36 --androidx "compose,lifecycle,activity"Optionally download LSP servers
For advanced cross-file analysis (go-to-definition, find-references, type documentation), download the Language Server Protocol servers. This is optional but recommended for deep exploration.
android-source-explorer sync --lspConfigure your MCP client (basic)
Add android-source-explorer to your MCP client configuration. The server starts in serve mode and exposes tools for searching and reading Android source code.
{
"mcpServers": {
"android-sources": {
"command": "android-source-explorer",
"args": ["serve"]
}
}
}Enable LSP tools (optional)
Set the ANDROID_SOURCE_LSP environment variable to true to activate cross-file definition resolution and reference finding through the LSP engine.

"mcpServers": {
"android-sources": {
"command": "android-source-explorer",
"args": ["serve"],
"env": {
"ANDROID_SOURCE_LSP": "true"
}
}

}Prompts to try
Use natural language to explore AOSP internals and Jetpack library code.
- "Show me the source code for ActivityResultLauncher in AndroidX Activity"
- "How does Compose's remember() function work internally? Show the implementation"
- "Find all classes that extend ViewModel in the lifecycle library"
- "What methods does the Android Binder class expose? List them with signatures"
- "Search for usages of CoroutineScope in the Jetpack Lifecycle source"Troubleshooting AOSP Explorer
android-source-explorer command not found after installation
Ensure the uv tool bin directory is in your PATH. Run 'uv tool update-shell' or add $(uv tool dir)/bin to your PATH in your shell profile (~/.zshrc or ~/.bashrc).
Sync fails or downloads incomplete source
Check your internet connection and available disk space. Re-run the sync command — it supports resuming. If a specific AndroidX module fails, try syncing modules individually by name.
LSP tools are not available despite setting ANDROID_SOURCE_LSP=true
You must first run 'android-source-explorer sync --lsp' to download the LSP server binaries. After downloading, restart the MCP server and the LSP-powered tools will appear.
