  Virix Labs is the trading name of Virix Ltd, a London software company (England & Wales no. 16325097,
  incorporated March 2025) that builds and operates Human Browser at humanbrowser.cloud: a hosted "cloud
  Chromium for AI agents" that runs a natural-language browser goal on a residential IP behind a live viewer
  a person can watch and take over, with CAPTCHA handling, persistent per-token cookie profiles and metered
  prepaid pricing ($0.10 per browser-minute, $4/GB bandwidth, $0.005 per solved CAPTCHA). The same runtime is
  exposed four ways: an A2A 0.3.0 agent card at /.well-known/agent-card.json with nine skills and a JSON-RPC
  endpoint at agent.humanbrowser.cloud/a2a; a Model Context Protocol server both hosted
  (agent.humanbrowser.cloud/mcp, with RFC 9728 protected-resource and RFC 8414 authorization-server metadata)
  and shipped as a stdio server in the npm package @virixlabs/humanbrowser; a six-operation OpenAPI 3.1.0
  REST account API at humanbrowser.cloud/openapi.json; and an OpenAI plugin manifest plus llms.txt. Virix
  Labs also sells agent-run marketing and web-operations services at virixlabs.com.

    Model Context Protocol access to the same browser runtime, shipped two ways: a hosted Streamable HTTP
    endpoint at https://agent.humanbrowser.cloud/mcp that requires the hb_live_ bearer token (anonymous
    initialize and tools/list answer 401 with WWW-Authenticate: Bearer realm="humanbrowser-mcp"; 60 requests
    per 60 s per token) and a stdio server inside the npm package (`npx -y @virixlabs/humanbrowser mcp`,
    HB_TOKEN env). The package source exposes three tools — humanbrowser_run, humanbrowser_stream, humanbrowser_viewer_url
    — with JSON-Schema inputSchemas; the provider's MCP docs page describes a different six-tool surface
    that could not be verified. RFC 9728 protected-resource metadata names this endpoint as an OAuth resource
    (scopes mcp:run, mcp:read) with an authorization server on the same host.

    Agent2Agent protocol surface: an agent card (protocolVersion 0.3.0, JSONRPC, version 5.1.0) served
    byte-identically from https://agent.humanbrowser.cloud/.well-known/agent-card.json and the website
    apex, advertising nine skills — browser_task, login_and_scrape, meta_business_workflow, fill_form,
    scrape_url, relay_reverse_api, hostile_site_solver, email_verified_signup, network_discovery — reached
    through message/send or message/stream (SSE) at POST https://agent.humanbrowser.cloud/a2a with tasks/get
    and tasks/cancel, plus twelve provider "actions/*" JSON-RPC methods. Streaming, push notifications
    (callback_url) and an input-required human-in-the-loop pause with a documented resume contract; every
    call needs the hb_live_ bearer token (anonymous calls return HTTP 401 / JSON-RPC -32001). Graded conformant
    against A2A 1.0.0 hard checks.
