Auto Browser demo

Предоставьте своему ИИ-агенту настоящий браузер с возможностью участия человека.

Auto Browser — это управляющая панель браузера на базе MCP для авторизованных рабочих процессов. Она предоставляет клиентам MCP, ИИ-агентам и операторам общий браузер Playwright с возможностью перехвата управления человеком, повторно используемыми профилями аутентификации, одобрениями, журналами аудита и развертыванием по принципу «локально в первую очередь» (local-first).

Работает с:

Claude Desktop
Cursor
любым MCP-клиентом, поддерживающим HTTP или stdio
прямыми REST-запросами, если вам нужно управление через curl

Почему Auto Browser

MCP-native с первого дня. Интерфейс браузера изначально упакован как MCP-сервер, а не добавлен позже.
Перехват управления человеком, когда веб-интерфейс становится нестабильным. noVNC позволяет сохранить доступ к активной сессии, когда человеку нужно вмешаться.
Войдите один раз, используйте повторно. Сохраняйте именованные профили аутентификации и открывайте новые сессии, в которых вы уже авторизованы.
Local-first по умолчанию. Запускайте весь стек на своем компьютере с помощью Docker Compose или используйте Codespaces для быстрого ознакомления.
Встроенные механизмы безопасности. Одобрения, идентификация оператора, очистка персональных данных (PII), квитанции Witness и шаблоны соответствия требованиям — все это часть продукта.

Основные моменты релиза (v1.0.2)

Обновления безопасности фреймворка с фиксацией версий FastAPI и Starlette на текущей исправленной ветке
Более безопасные границы ошибок в действиях браузера, CDP, OCR, mesh, рабочих процессах, туннелях, социальных функциях и поверхностях обмена токенами
Усиление ограничения частоты запросов (rate-limit) с использованием ограниченных корзин и хешированных идентификаторов операторов
Ужесточение политики хостов и путей для производственных ALLOWED_HOSTS, путей профилей аутентификации и корневых каталогов загрузки
Платформенный интерфейс 1.0, включая делегирование mesh с подписью, маршруты рабочих процессов, /dashboard, перехват через noVNC, транспорт MCP, журналы аудита и проверки готовности

Полную историю релизов см. в CHANGELOG.md.

Для чего подходит

внутренние панели управления и инструменты администрирования
QA с участием оператора и отладка браузера
рабочие процессы с авторизацией «войти один раз, использовать позже»
нестабильные сайты, где человеку может потребоваться восстановить поток действий
рабочие процессы агентов на базе MCP, которым нужен настоящий браузер, а не просто получение HTML

Что не является целью

скрытная работа или обход защиты от ботов
разгадывание CAPTCHA
несанкционированный парсинг или автоматизация учетных записей
обманная подмена личности или инструменты обхода

Что вы получаете

Управление браузером	Безопасность оператора	Развертывание и интеграция
Сессии на базе Playwright со скриншотами, сводками DOM, выдержками OCR, управлением вкладками, загрузками и инспекцией сети	шлюзы одобрения, заголовки идентификации оператора, события аудита, очистка PII, квитанции Witness и профили защиты	MCP через HTTP, встроенный мост stdio, REST API, Docker Compose, Codespaces, профили аутентификации и опциональная изоляция сессий

Быстрый старт

git clone https://github.com/LvcidPsyche/auto-browser.git
cd auto-browser
docker compose up --build

Этого достаточно для локальной разработки с настройками по умолчанию.

Опционально:

cp .env.example .env
make doctor

Запустите make doctor из обычного терминала с доступом к локальному Docker и разрешением на открытие сокетов localhost.

Откройте:

Codespaces автоматически подготавливает стек. Панель управления и вкладки noVNC обычно готовы примерно через 90 секунд.

Первая полезная демонстрация

Наиболее показательный сценарий в этом репозитории:

создание сессии
ручной вход, если сайту нужен человек
сохранение сессии как именованного профиля аутентификации
открытие новой сессии из этого профиля
продолжение работы без повторной авторизации

Начните здесь:

Минимальное создание сессии:

curl -s http://127.0.0.1:8000/sessions \
  -X POST \
  -H 'content-type: application/json' \
  -d '{"name":"demo","start_url":"https://example.com"}' | jq

Минимальное наблюдение:

curl -s http://127.0.0.1:8000/sessions/<session-id>/observe | jq

MCP-клиенты

Auto Browser предоставляет:

HTTP MCP-эндпоинт по адресу http://127.0.0.1:8000/mcp
удобные эндпоинты http://127.0.0.1:8000/mcp/tools и http://127.0.0.1:8000/mcp/tools/call
встроенный мост stdio в scripts/mcp_stdio_bridge.py

Профиль инструментов MCP по умолчанию — curated, который сохраняет интерфейс браузера компактным для лучшего выбора инструментов. Если вам нужен полный набор внутренних инструментов, установите:

MCP_TOOL_PROFILE=full

Пример вызова инструмента:

curl -s http://127.0.0.1:8000/mcp/tools/call \
  -X POST \
  -H 'content-type: application/json' \
  -d '{
    "name":"browser.create_session",
    "arguments":{
      "name":"demo",
      "start_url":"https://example.com"
    }
  }' | jq

Руководства по настройке клиентов:

Безопасность и соответствие требованиям

Для реального частного развертывания установите как минимум:

APP_ENV=production
API_BEARER_TOKEN=<strong-random-secret>
REQUIRE_OPERATOR_ID=true
AUTH_STATE_ENCRYPTION_KEY=<44-char-fernet-key>
REQUIRE_AUTH_STATE_ENCRYPTION=true
REQUEST_RATE_LIMIT_ENABLED=true
METRICS_ENABLED=true

COMPLIANCE_TEMPLATE может применить предварительно настроенную политику при запуске:

Шаблон	Шифрование Auth	ID оператора	Очистка PII	Изоляция	Макс. возраст сессии
`HIPAA`	требуется	требуется	все уровни	`docker_ephemeral`	4ч
`PCI-DSS`	требуется	требуется	все уровни	`docker_ephemeral`	1ч
`SOC2`	-	требуется	сеть + текст	общий	24ч
`GDPR`	-	-	все уровни	общий	24ч

Все шаблоны требуют одобрения загрузок. HIPAA, SOC2 и PCI-DSS также включают квитанции Witness. При запуске примененная политика записывается в /data/compliance-manifest.json.

Пример:

COMPLIANCE_TEMPLATE=HIPAA docker compose up

TDQS

A3.9/5.0

Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations indicate readOnlyHint=false and destructiveHint=false, but the description does not elaborate on behavioral traits beyond returning element data. It does not clarify whether the tool modifies browser state (e.g., scrolling) or has side effects. Given that annotations already cover some aspects, the description adds minimal extra transparency.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description consists of two concise sentences: the first states functionality and return data, the second provides usage context. There is no redundant information, and every word adds value.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The tool is simple with three parameters and no output schema. The description covers the main purpose and return data, which is sufficient for basic usage. However, it omits details like error handling, performance considerations for large selectors, or the exact format of the bounding box. Still, given the low complexity, it is adequately complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has 33% description coverage; only session_id has a description. The tool description does not explain the 'limit' parameter (default 20, max 100) or the 'selector' parameter (CSS format). It mentions returning 'all elements' but does not clarify the effect of the limit, which could mislead an agent into expecting unlimited results.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool finds all elements matching a CSS selector and returns specific properties (text, href, etc.). The verb 'find' and resource 'elements' are unambiguous, and it distinguishes itself from the sibling tool 'browser.list_memory_profiles' which has a completely different purpose.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description includes a usage hint 'Useful before clicking or scraping multiple items,' providing context for when to use the tool. However, it does not explicitly mention when not to use it or alternative tools for similar tasks, but the sibling tool is unrelated, so differentiation is not critical.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

browser.list_memory_profilesA

Read-onlyIdempotent

List all saved memory profiles.

ParametersJSON Schema

Name	Required	Description	Default
No parameters

TDQS

A3.8/5.0

Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint=true and idempotentHint=true, so the description adds no additional behavioral context beyond confirming the read-only nature.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, clear sentence with no unnecessary words, achieving maximum conciseness.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's simplicity (no parameters, straightforward purpose) and strong annotations, the description adequately covers the context, though it lacks return format details.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With zero parameters and 100% schema coverage, the baseline of 3 applies as the description adds no parameter-specific meaning.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action (list) and resource (all saved memory profiles), accurately distinguishing it from related tools like get_memory_profile and save_memory_profile.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage for listing saved profiles but does not explicitly discuss when to use this tool over alternatives or provide any exclusions.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

A3.6/5.0

Disambiguation5/5

The two tools serve completely different purposes: one lists saved profiles, the other finds DOM elements. There is no overlap or ambiguity.

Naming Consistency5/5

Both tools consistently use the 'browser.' prefix followed by a verb_noun pattern in snake_case (list_memory_profiles, find_elements).

Tool Count1/5

Only 2 tools for a browser automation server is far too few. Essential operations like navigation, clicking, input, and scraping are missing, making the tool set feel incomplete for its stated domain.

Completeness1/5

The tool surface is severely incomplete. There is no way to navigate, interact with elements, or scrape content, leaving agents unable to perform basic browser automation tasks.
