What it does

Skyvern is an agent skill from davepoon/buildwithclaude. AI-powered browser automation — navigate sites, fill forms, extract structured data, log in with stored credentials, and build reusable multi-step workflows using natural language. Install: pip install skyvern && skyvern setup

Its SKILL.md is about 500 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Productivity & Automation, covering Browser automation, Forms and invoices and Schema markup. The repository describes itself as: A single hub to find Claude Skills, Agents, Commands, Hooks, Plugins, and Marketplace collections to extend Claude Code, Claude Desktop, Agent SDK and OpenClaw. The licence is MIT.

When your agent uses it

  • Tasks that involve Browser automation
  • Tasks that involve Forms and invoices
  • Tasks that involve Schema markup

Example prompts

  • “/skyvern”

Requirements

  • Python 3
  • A credential in YOUR_SKYVERN_API_KEY

What it can do on your machine

Read from SKILL.md and the folder at commit 616deb5. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • pip

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • api.skyvern.com

    Also links to:

    • skyvern.com
    • github.com
    • discord.gg

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Skyvern loads about 496 tokens when it runs. Until then it costs about 59 tokens; SKILL.md has 127 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~59
When it runs · the whole SKILL.md, loaded when a task matches
~496

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Skyvern Browser Automation

Control a real browser with natural language. Skyvern uses Vision LLMs and computer vision instead of brittle XPath/DOM selectors, so automations survive UI changes.

Setup

Cloud (recommended):

bash
pip install skyvern
skyvern setup  # interactive client selection

Or add the MCP server directly to your Claude Code config:

json
{
  "mcpServers": {
    "skyvern": {
      "type": "streamable-http",
      "url": "https://api.skyvern.com/mcp/",
      "headers": {
        "x-api-key": "YOUR_SKYVERN_API_KEY"
      }
    }
  }
}

Get your API key at app.skyvern.com.

  • Natural language actions — click, type, scroll, hover, drag-and-drop via plain English
  • Structured extraction — extract data with JSON schema validation and screenshot reasoning
  • Secure login — credential vault with 2FA/TOTP support (QR, email, SMS)
  • Reusable workflows — 23 block types, parameterized runs, cached scripts (10-100x faster on repeat)
  • 75+ MCP tools — session management, multi-tab, iframes, network inspection, HAR recording
  • Works with — Claude Desktop, Claude Code, Cursor, Windsurf, Codex
