replicant-mcp
Let AI build, test, and debug your Android apps.
replicant-mcp is a Model Context Protocol server that gives AI assistants like Claude the ability to interact with your Android development environment. Build APKs, launch emulators, install apps, navigate UIs, and debug crashes—all through natural conversation.
