52 Tools.
One MCP Server.
Total Web Intelligence.

Tap into any website's DNA — design tokens, accessibility scores, tech stacks, security headers — all returned as structured JSON your AI agent can act on. Your agent decides which tools to call, combines the results, and presents them however you ask — a competitive teardown deck, an accessibility audit report, a design token file ready to drop into your codebase. 52 extraction tools. Infinite ways to use them. Runs locally. Supports authenticated sessions behind MFA and SSO. Zero config.

Key Capabilities

palette

Design System Extraction

Extract color palettes, typography rules, spacing scales, CSS variables, shadows, and component patterns from any website. Get the complete design DNA as structured JSON.

COLORS FONTS CSS-VARS SPACING SHADOWS COMPONENTS
lock_open

Authenticated Browsing

Log in once through a headed browser — MFA, SSO, whatever the site requires. Session persists across all tool calls. Credentials never touch the wire.

shield

Prompt Injection Defense

Hidden element filtering at extraction time plus output sanitization before anything reaches your LLM. Two layers, zero trust.

Security & Accessibility Audits

CSP scoring, SRI checks, WCAG compliance, contrast ratios — actionable letter grades, not just raw data.

dns

Tech Stack Intelligence

Framework detection, third-party script classification, storage profiling, WASM analysis — know what's under the hood.

52 Tools, 6 Modules

Every tool returns structured JSON designed for LLM context windows. One MCP server, modular by design.
