Which one, for what

Hyperbrowser B

Good for Agents that need a cloud browser by the minute plus cheap fetch and search, especially wallet-holding agents with no account.

Ahead on

  • Reliability, 65 against 57
  • Payments & pricing, 94 against 32

Also in its favour

  • An agent can pay per call over x402, with no account
  • No incidents deducted, where Skyvern loses 3 points for them

Watch for

The official MCP server's last npm release is 1.0.25 of 13 April 2025, and it isn't in the official MCP registry

Skyvern B

Good for Agents that must finish a multi-step job on sites with logins, 2FA and forms, where stored credentials, saved workflows and cached scripts matter more than raw browser time.

Ahead on

  • Schema & documentation, 88 against 68
  • Agent ergonomics, 76 against 67
  • Security & auth, 59 against 44
  • Maintenance & community, 85 against 79
  • Transparency & trust, 72 against 64

Also in its favour

  • Open source

Watch for

Every API key and OAuth token has full organisation authority. The docs state there are no read-only, per-endpoint or per-resource keys

Verdicts

Hyperbrowser

Sessions, Fetch and Search can be bought by x402 at api.hyperbrowser.ai with USDC on Base or Solana and no account, and unit prices are public. The official MCP server was last published in April 2025, no request rate limits or SLA are published, and the privacy notice covers only the website.

Skyvern

The hosted MCP server annotates every tool as read-only or destructive and can advertise a 29 or 32-tool subset in place of 114, and the API has a written six-month deprecation policy. Every key and OAuth token carries full organisation authority, with no read-only or scoped credential, and no request rate limits are documented.

Before you call either

Hyperbrowser

  1. With a wallet and no key, POST to https://api.hyperbrowser.ai/x402/session and read the PAYMENT-REQUIRED header. Sessions are prepaid for 5 to 60 minutes with no refund
  2. Save the x402 creation response. It holds the only copy of the connection tokens, and managementToken is what stops the session
  3. Stop sessions explicitly in cleanup code. Browser time bills per second until the timeout
  4. Use Fetch at $0.001 a page for static pages and keep browser sessions for pages that need interaction
  5. Add &keepAlive=true to wsEndpoint to reconnect after a CDP disconnect. Treat that URL as a secret because it carries the session token

Skyvern

  1. Connect to https://api.skyvern.com/mcp/x/lean or /x/operate, or send X-Skyvern-Scope, so the client loads 32 or 29 tools. The scope filters the list and does not limit permissions
  2. Use a separate Skyvern organisation for each blast radius. Any key or OAuth token can read and write stored credentials and delete workflows
  3. Never pass passwords to skyvern_act or skyvern_type. Store them as credentials and call skyvern_login
  4. Set max_steps on tasks, or x-max-steps-override on agent runs, to cap credits. A run that reaches the cap ends as timed_out
  5. On 503 from POST /v1/run/agents, wait Retry-After seconds. No run was created, so resubmitting is safe

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
