How to Join the Alpha
Two steps — takes about 60 seconds.
Join the Testers Group
You need to be a member of the Google Group before Google Play will let you opt in to the alpha. Click below and join with the same Google account you use on your Android device.
Side-load the APK directly
Skip the Play Store entirely. Download the latest .apk from GitHub Releases and install it manually. You'll need to enable "Install from unknown sources" in your Android settings.
A nervous system for AI agents
VAGUS MCP transforms your Android device into a sensory endpoint for AI agents. It's not another chatbot wrapper — it's an embodiment layer that gives agents the ability to perceive the physical world through device sensors and act back through device outputs.
Senses flow up. An inference layer adds contextual meaning — is the user walking? sleeping? indoors? paying attention? Actions flow down — haptics, speech, notifications, SMS. Every capability is individually governed by you, with per-tool rate limits, time-of-day windows, and approval prompts.
Built on the Model Context Protocol (MCP). Any MCP-compatible agent — Claude, GPT, Openclaw, n8n, custom frameworks — connects to the physical world through VAGUS.
Capabilities
Motion & Position
Accelerometer, gyroscope, GPS, orientation. Proprioceptive grounding for spatial awareness.
SENSEEnvironment
Light, pressure, proximity, temperature, humidity. Ambient awareness of the physical world.
SENSEDevice State
Battery, connectivity, screen, notifications, clipboard. Awareness of its own substrate.
SENSEActivity Recognition
Physical activity classification — still, walking, running, cycling, in vehicle.
INFERAttention & Sleep
Inferred attention availability and sleep likelihood from screen, motion, light, and time.
INFERIndoor Confidence
Probability score for being indoors based on ambient sensor fusion and device signals.
INFERHaptics & TTS
Haptic pulse patterns and text-to-speech. The agent reaches back through touch and voice.
ACTNotify, SMS, URL
Post notifications, send SMS messages, open URLs. Agent actions in the real world.
ACTGovernance
Per-capability toggles, rate limits, time windows, approval prompts, full access logs.
