Stop writing brittle test scripts. Start having conversations with your browser.

CBrowser provides 120 MCP tools that let Claude automate browsers using natural language. No CSS selectors. No XPath. No "element not found" errors at 3am. Just describe what you want to do, and CBrowser figures out the rest.

The Problem We Solve

Traditional browser automation breaks constantly:

Selectors drift — A developer changes a CSS class and your entire test suite fails
Timing issues — Pages load at different speeds, tests randomly fail
Maintenance burden — You spend more time fixing tests than writing features
No user insight — Tests tell you if buttons click, not if humans can use your product

CBrowser fixes this with AI-powered automation that:

Self-heals when the DOM changes
Waits intelligently for content, not arbitrary timeouts
Simulates real users with patience, frustration, and abandonment
Works through conversation — describe intent, not implementation

Tool Tiers

Tier	Tools	Access	Best For
Demo	94 base + 20 stubs + 6 marketing	Free at `demo.cbrowser.ai/mcp`	Evaluation, small projects, learning
Enterprise	120 tools (all functional)	Self-hosted or authenticated	Production use, marketing intelligence, stealth testing

The Demo tier gives you everything you need to automate browsers, run tests, and simulate users. Enterprise adds autonomous AI execution, marketing campaign analysis, and bot detection bypass for authorized testing.

Tools by Capability

Browser Automation — 19 tools

Navigate, click, fill forms, extract data, take screenshots, hover, type text, press keys, drag and drop, upload files, handle JS dialogs, and execute JavaScript. All tools support _browserToken for session continuity. AI-powered element resolution with self-healing selectors.

Visual & Performance — 15 tools

Visual regression, cross-browser testing, responsive testing, performance baselines. Wasserstein optimal transport for smart baselines (barycenter consensus), transport maps (where content moved), and attention analysis (W₂ CIE-Lab persona saliency).

Cognitive & Journey — 8 tools

Simulate real users with 26 cognitive traits. Cognitive Optimal Transport: Wasserstein distance between personas, geodesic interpolation, adversarial generation via DRO, cognitive load estimation. Journey validation with goal evidence verification.

Persona System — 14 tools

Create personas from descriptions, questionnaires, or manual traits. 26 research-backed cognitive traits, Schwartz universal values, SDT psychological needs. Wasserstein distance matrix in persona comparisons.

Testing & Quality — 10 tools

Natural language tests, auto-repair broken selectors, detect flaky tests, map coverage, hunt bugs, chaos engineering. No code required.

Marketing Intelligence — 10 tools

Test psychological influence patterns (Cialdini's 6 principles) against different audience segments. Campaign simulation, funnel analysis, competitive benchmarking.

Accessibility — 2 tools

Empathy audits with perceptual transport (Wasserstein visual information loss), cognitive load (8-dimension per-persona), and attention transport (persona-filtered W₂ saliency). Different personas produce different scores: motor=19, ADHD=21, color-blind=57.

Session & Browser — 15 tools

Save/restore browser state, health checks, crash recovery, self-healing cache stats, tab management, cookie management, localStorage/sessionStorage access, console log capture, and network request inspection. _browserToken enables session continuity across MCP proxy calls.

Utilities & AI Friendliness — 19 tools

AI agent readiness audits (A-F grades), llms.txt management, security scanning, stealth mode (Enterprise), API key management, structured data suggestions.

Quick Start

1. Connect to the Demo MCP (free, rate-limited):

URL: https://demo.cbrowser.ai/mcp

2. Or run locally (no rate limits):

npx cbrowser mcp-server

3. Start automating:

Navigate to https://example.com
Click the "Get Started" button
Fill the email field with "[email protected]"
Take a screenshot

That's it. No setup, no configuration, no selectors.

Enterprise Features

Enterprise adds capabilities that require either:

API credits (autonomous AI journeys that make decisions)
Security attestation (stealth/Cloudflare bypass requires domain authorization)
Compute resources (marketing campaigns that run hundreds of journeys)

Feature	Why It's Enterprise
Autonomous Journeys	AI makes decisions, consumes API credits
Marketing Execution	Runs campaigns with real cognitive journeys
Marketing Analysis	Influence matrices, lever analysis, funnel comparison
Stealth Mode	Constitutional bypass requires signed authorization
Cloudflare Handling	Challenge bypass for authorized domains only

Demo users can still:

Set up marketing campaigns and report results manually
Run cognitive journeys with Claude orchestrating (no server-side autonomy)
Use all 72 core automation, testing, and persona tools
