CortexScout (cortex-scout) — Search and Web Extraction Engine for AI Agents

CortexScout is the Deep Research & Web Extraction module within the Cortex-Works ecosystem.

Designed for agent workloads that require token-efficient web retrieval, reliable anti-bot handling, and optional Human-in-the-Loop (HITL) fallback.

Overview

CortexScout provides a single, self-hostable Rust binary that exposes search, extraction, and stateful browser automation capabilities over MCP (stdio) and an optional HTTP server. Output formats are structured and optimized for downstream LLM use.

It is built to handle the practical failure modes of web retrieval (rate limits, bot challenges, JavaScript-heavy pages) through progressive fallbacks: native retrieval → Chromium CDP rendering → Stateful E2E Testing → HITL workflows.

Tools (Capability Roster)

Legacy names remain callable as compatibility aliases (web_search_json, web_fetch_batch, web_crawl, fetch_then_extract, human_auth_session). Agents should prefer the unified primary tools above.

Ecosystem Integration

While CortexScout runs as a standalone tool today, it is designed to integrate with CortexDB and CortexStudio for multi-agent scaling, shared retrieval artifacts, and centralized governance.

🎭 The "Playwright Killer" (Stateful Browser Automation)

CortexScout includes a built-in, stateful CDP automation engine designed specifically for AI Agents, completely replacing heavy frameworks like Playwright or Cypress for E2E testing workflows.

• The Silent Omni-Tool (scout_browser_automate): Instead of calling dozens of browser tools, agents pass one array of steps. The runtime now covers Playwright-style action families in one call: navigation, hover/click/type/wait, locator-driven actions, assertions, tabs, screenshots/PDF, file upload, form fill, dialog policy, coordinate mouse actions, route mocking, console/network capture, and cookie/storage CRUD.
• Persistent Agent Profile: Automation runs silently in the background (--headless=new) using a dedicated isolated profile (~/.cortex-scout/agent_profile). It maintains cookies, localStorage, and session state across tool calls without causing SingletonLock collisions with your active desktop browser.
• QA Mock, Trace, And Verification Engine: Agents can install route mocks (mock_api, route_list, unroute) with response header overrides/stripping, trace flows (trace_start, trace_stop, trace_export), capture console/network logs, checkpoint browser state, and run both CSS and locator-based assertions plus Playwright-style verification helpers.
• The Agent Auth Portal (scout_agent_profile_auth): If the silent agent encounters a CAPTCHA or complex OAuth login
