🛑 The Problem: Agentic Workflows Are Blind

We're in the era of autonomous AI Agents — but the web was built to repel bots, not serve them.

When your Claude, Cursor, or Windsurf tries to read an obscure API's documentation, it gets annihilated by:

1. Cloudflare WAFs throwing 403 CAPTCHAs at Node.js fetch().

2. Empty SPA shells (Next.js, Mintlify, GitBook) that render nothing without a $300M headless browser.

3. Legacy enterprise PDFs that crash the model's context window.

4. Login walls that lock public API references behind OAuth gates.

5. "AI-friendly" SaaS tools (Firecrawl, Jina, Context7) charging you $50/mo to read pages that are already public.

The LLM doesn't need a middleman. It needs raw signal.

⚔️ The Weapon: Guerrilla Architecture

DocBreach is a ruthless, 100% local MCP server. It doesn't ask for permission. It uses military-grade heuristics to extract clean, LLM-optimized Markdown from any developer portal — and it does it for free, forever.

"The LLM shouldn't be smart at scraping. It should be smart at coding. DocBreach handles the dirty work."

🚀 Quickstart

Claude Desktop

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "docbreach": {
      "command": "npx",
      "args": ["-y", "doc-breach-mcp"]
    }
  }
}

Cursor / Windsurf

Add to your MCP settings:

{
  "doc-breach": {
    "command": "npx",
    "args": ["-y", "doc-breach-mcp"]
  }
}

That's it. No API keys. No .env files. No sign-ups. It just works.

🧠 How It Thinks

DocBreach gives your AI agent 4 precision tools and lets the model drive:

You: "Integrate with the Datadog API and list all monitors"

Agent → docs.discover({ query: "datadog API" })
     ← Found: docs.datadoghq.com/api/latest/ (openapi)

Agent → docs.map({ domain: "docs.datadoghq.com" })
     ← 🗺️ Sitemap hierarchy, auto-generated Mermaid graph, and llms.txt discovery

Agent → docs.read({ url: "https://docs.datadoghq.com/api/latest/" })
     ← 📄 Clean Markdown + nav links + auth requirements

Agent → docs.extract({ url: "https://api.datadoghq.com/api/v2/openapi.yaml", tag: "monitors" })
     ← 📋 GET /api/v1/monitor — List all monitors
        GET /api/v1/monitor/{id} — Get a monitor's details
        POST /api/v1/monitor — Create a monitor
        ...

Agent: "I see the API requires DD-API-KEY and DD-APPLICATION-KEY headers,
        and you need to select a DD_SITE (US1, EU, US3, US5, AP1)..."

The model reasons. DocBreach retrieves. Nobody hallucinates.

The 11-Step Reader Pipeline

Every URL passes through a battle-hardened, 11-step extraction pipeline:

 URL
  │
  ├─ 1. Preflight ──────── HEAD check → Content-Type, size, reject >10MB
  ├─ 2. Fetch ──────────── GET + Wayback Machine fallback on 403/503
  ├─ 3. Login Detection ── OAuth/SSO wall? → abort + guide agent
  ├─ 4. Format Detection ─ OpenAPI? Postman? PDF? llms.txt? Markdown?
  ├─ 5. Binary Handling ── PDF <5MB → in-memory parse
  ├─ 6. Spec Summary ───── OpenAPI/Postman → structured Markdown
  ├─ 7. SPA Hydration ──── __NEXT_DATA__, __NUXT__, readme-data, GitBook
  ├─ 8. Nav Extraction ─── Sidebar links → absolute URLs
  ├─ 9. iFrame Intel ───── Swagger/Postman/Stoplight embed → true URL
  ├─ 10. HTML Cleaning ─── Cheerio → remove headers, footers, ads, nav
  └─ 11. Markdown ──────── Turndown + boundary-aware truncation

 Clean, LLM-ready Markdown

🪖 The Uncomfortable Truth

The developer tooling market has a parasite problem.

Companies like Firecrawl, Jina Reader, and Context7 take public documentation — pages that are freely accessible to any browser — wrap them in a proprietary API, and charge you a monthly subscription to access what was already yours.

They aren't adding value. They're adding a toll booth to the public internet.

DocBreach exists because:

• Documentation is public. If a human can read it, an agent should too.

• Scraping is a solved problem. Cheerio + Turndown have existed for a decade. You don't need a $20M startup to parse HTML.

• Your AI runs locally. Why should it phone home to a SaaS to read a README?

This is not a product. This is a crowbar.

📊 DocBreach vs. The Toll Booths

🔧 Tools Reference

docs.discover

Find documentation sources for any service, library, or API.

docs.discover({ query: "stripe webhooks API" })
// → [ { url, title, type: "openapi", source: "probe" }, ... ]

docs.map

Map the complete documentation structure of any domain. Extracts sitemaps, robots.txt, and llms.txt, returning an architectural blueprint.

docs.map({ domain: "docs.stripe.com" })
// → { total: 1200, sections: { "Root": [...], "API": [...] }, ... }

docs.read

Read any documentation URL and return clean, LLM-ready Markdown.

docs.read({ url: "https://docs.stripe.com/webhooks" })
// → { content: "# Webhooks\n\n...", nav_links: [...], format: "html" }

docs.search

Search for specific topics within a documentation site.

docs.search({ query: "authentication", site: "docs.stripe.com" })
// → [ { url: ".../authentication", title: "Authentication", ... } ]

docs.extract

Extract structured endpoint information from OpenAPI/Swagger/Postman specs.

docs.extract({ url: "https://api.stripe.com/openapi/spec.json", tag: "charges" })
// → [ { method: "POST", path: "/v1/charges", summary: "Create a charge" }, ... ]

🏆 Beyond the MCP Specification

Google and Anthropic's official MCP best practices ask for "Single Responsibility," "Clear Descriptions," and "Structured Error Handling." That is the bare minimum.

Thanks to Vurb.ts, DocBreach elevates these concepts to the tenth power, operating years ahead of the standard protocol:

• MVA Architecture (Model → View → Agent): Standard MCP returns raw JSON strings. We route everything through Fluent Presenters acting as smart egress firewalls, stripping noise before the LLM ever sees it.

• HATEOAS Navigation: Instead of the agent guessing what to do next, every DocBreach response includes a .suggestActions() payload telling the model exactly which tool to call next.

• JIT System Rules: Dynamic instructions injected mid-flight based on payload context (e.g., "The content was truncated, use search").

• Self-Healing Errors: Standard MCP throws an error. DocBreach returns an error and the exact prompt/tool required to recover from it.

• Server-Side Mermaid UI: Sends native ui.mermaid() visual graphs to the MCP Inspector to help humans see the architecture the agent sees.

• State Sync & Cache Control: Emits .cached() directives at the protocol level to eliminate duplicate requests and save LLM token context.
