Automate any website with Skyvern's AI browser agents: run natural-language tasks, run saved agents (workflows), and manage runs, browser sessions, browser profiles and credentials.
Skyvern ships in the w6w first-party pack. It declares 20 actions, 3 health checks, and the host runs its code in a sandbox that never sees the credential.
io.w6w.skyvernSkyvern drives a real browser with LLMs and computer vision, so a workflow can automate websites that have no API: log in, fill forms, extract data, download files and complete multi-step jobs from a plain-language goal.
Two things can be run. A task is a one-off goal (a prompt, an optional start URL and an optional data-extraction schema). An agent is a saved, reusable multi-step automation (what older Skyvern docs and operation ids call a workflow) that is started by id with parameters. Both produce a run: poll it, read its output, cancel it, list past runs, or pull its artifacts (recordings, screenshots, logs) and its block-by-block timeline.
The app also manages the pieces a run uses: persistent browser sessions (keep a live browser across several runs, extend or close it), browser profiles (saved cookies and local storage to stay logged in), and stored credentials (listed by name and type; Skyvern never returns the secret).
This app covers Skyvern Cloud (api.skyvern.com). Scripts, schedules, tags, folders, custom LLMs, job recipes, creating or editing agents, and writing credentials are left out and listed in the README.
Three routes to the same 20 actions. The Workflow tab is generated from Skyvern's own manifest and carries its real ids, so it is copy-pasteable; the Code and CLI examples are the same call for any action on any app, so every app-specific value in them is a blank you fill in.
browser-profile-list List saved browser profiles (persisted cookies and local storage).
browser-session-close Close a browser session so it stops billing; `completed_at` is set when it ends.
browser-session-create Start a persistent browser session. Pass its id to Run Task / Run Agent to keep login state and page context across runs.
browser-session-extend Add minutes to a running browser session's deadline (up to 360 minutes in total).
browser-session-get Fetch a browser session: status, address, downloaded files and recordings.
credential-list List stored credentials by name and type, to reference them in an agent. Secrets are never returned.
run-agent Start a saved Skyvern agent (workflow) by id with parameters. Returns the new run; poll it with Get Run.
run-artifacts List a run's artifacts (recording, screenshots, logs, HTML) with signed download URLs.
run-get Fetch a run's status, output, failure reason, recording and screenshots. Poll until `status` is terminal.
run-task Start a one-off Skyvern task from a plain-language goal. Returns the new run; poll it with Get Run.
run-timeline Fetch the ordered blocks and thoughts of an agent run, with each block's status and output.
A workflow step names the app and the action, and the editor fills in the
connection when you pick one. This is the Step shape from the
workflow spec, carrying Skyvern's real ids.

Every app-specific value here is a blank you have to fill in. An
app action is reached through the connection that authenticates it, so the
address is a connection id, not the app id — and connections belong to your account,
so a public page cannot know yours. Create one for Skyvern, then fill in
the three blanks: conn_YOUR_CONNECTION_ID, the action key, and the
parameters that action declares. The call itself is real — the shape is transcribed
from the studio's own snippet builder, which prints the same kind of blanks — but
nothing in it is specific to Skyvern. The Workflow tab is where this app's
real ids are.
npm install @w6w/sdkyarn add @w6w/sdkpnpm add @w6w/sdkdeno add npm:@w6w/sdkimport { W6wClient, isActionRun } from "@w6w/sdk";
// Reads W6W_BASE_URL and W6W_TOKEN from the environment when omitted.
const client = new W6wClient();
const envelope = await client.run({
urn: "conn_YOUR_CONNECTION_ID",

payload: {
agentId: "<value>",
// version: "<value>",

if (isActionRun(envelope)) console.log(envelope.value); npm install -g @w6w/cli w6w run conn_YOUR_CONNECTION_ID --action agent-get --payload '{"agentId":"<value>"}' Give an AI agent Skyvern — without giving it Skyvern's credentials. One MCP endpoint exposes every app, function and workflow the caller is entitled to, as tools it can discover and run. Access is granted per team while we onboard.
One tool call{
"name": "w6w_invoke",
"arguments": {
"ref": "app:io.w6w.skyvern#agent-get",
"input": {
"agentId": "<agentId>"
}
}
}
Every tool names its target with a single ref. The
app: form above doesn't name a connection at all — the
host resolves which of the caller's Skyvern connections to sign
with, and refuses rather than guesses when the answer is ambiguous.
The token is attached host-side, at the moment of the call. It is never a tool argument, never in the model's context, and never in a transcript — so a prompt injection has nothing to exfiltrate.
Tools are derived per end user from what that person has actually connected and is entitled to — not one shared bot identity carrying the union of everyone's access.
Multi-step work runs on the workflow engine and returns a run handle the agent can poll — retries, branching and state survive the conversation that started them.
Skyvern's declared health checks are on the surface too, so an agent can tell "the vendor is down" from "your credential expired" before it burns a retry on either.
The MCP surface is part of the hosted platform. Skyvern itself is MIT, and the runtime that executes it is source-available (FSL).
Skyvern declares its own checks, so its health is a property of the app rather than something the host guesses at.
The `Skyvern API` and `Skyvern Async Workers` components on Skyvern's Statuspage; the web application component is reported as detail only.
Unauthenticated GET https://api.skyvern.com/v1/version. A 200 carrying `{"version": …}` (or a 403 carrying Skyvern's `{"detail": …}`) proves the API is serving. Key validity is the derived `auth:*` check's job.
