Model Context Protocol (MCP)

The Token-Efficient Browser Bridge for AI Agents

Connect Claude Desktop, Cursor, and Antigravity to your active Chrome sessions. 95% token pruning (<1,000 tokens/page) vs 80,000+ raw HTML dumps.

Why Existing Browser MCPs Fail

Raw Chrome DevTools protocol wrappers destroy LLM reasoning in 2 turns.

Raw Chrome DevTools MCP / Puppeteer

Context Window Exhaustion

❌ 50,000–100,000+ tokens of raw HTML dumped into context per turn.
❌ Cold Sandbox Profile: Zero cookies, no passwords, logged out of your SaaS apps.
❌ High Latency: 6–10 second model roundtrips parsing massive DOM trees.
❌ Destructive Tabs: Overwrites your active work tabs without isolation.

Aether Browser MCP

Token-Pruned Semantic Action Maps

✅ <1,000 tokens per turn via sequential numeric element anchors ([1], [2], [3]).
✅ Active Session Continuity: Runs in your daily Chrome profile with active logins.
✅ Near-Instant Response: Sub-second latency and minimal token consumption.
✅ Dedicated Tab Groups: Isolates tasks in a dedicated ⚡ Aether Agent tab group.

Built for Production AI Workflows

Designed for reliability, speed, and privacy.

Numbered Anchor Serialization

Prunes scripts, styles, SVGs, and invisible nodes. Interactive elements receive clean numeric IDs so models can act deterministically.

Active Profile Session Reuse

Operates directly in your authenticated Chrome browser session via Native Messaging. No re-logging into GitHub, Jira, AWS, or Stripe.

Non-Destructive Tab Grouping

Browsing and navigation automatically spawn inside an isolated cyan Chrome Tab Group, keeping your personal active tabs pristine.

Universal Protocol (MCP)

Works out of the box with Claude Desktop, Cursor IDE, Antigravity, OpenDevin, and any custom agent harness.

Local-Only IPC Execution

All serialization runs strictly on localhost (127.0.0.1). Zero telemetry, zero external cloud relays, 100% private.

Synthetic Interaction Pipeline

Full event dispatching (pointerover, mousedown, click, keydown, input, change) compatible with modern React, Vue, and SPAs.

Aether Browser Bridge is an open-source tool created by Studio Dao. The extension is architected for zero-data collection and 100% local execution.

• Zero External Telemetry: The extension does not collect, track, record, or transmit your personal data, passwords, cookies, or web history to external servers.

• Local IPC: All communication is restricted to local IPC between your Chrome extension and the local MCP server running on 127.0.0.1.

• In-Memory Parsing: DOM elements are serialized in-memory strictly when your local AI client invokes the tool. No browsing history is stored.
