@pipeworx/skyvern

Run an AI browser agent against a source that publishes no API (search forms, logins, multi-step lookups) and get the extracted result back.

Part of Pipeworx — an MCP gateway connecting AI agents to 1869+ live data sources. This is an independent, unofficial integration — not affiliated with, endorsed by, or published by the upstream provider.

Tools

• skyvern_run_task(prompt, url?, data_extraction_schema?, max_steps?, wait_seconds?) — start a run described in plain language and wait up to wait_seconds (default 20) for it. Finished runs return output; unfinished ones return finished: false and a run_id.

• skyvern_get_run(run_id, wait_seconds?) — status and output of a run, optionally waiting for it. Final statuses: completed, failed, terminated, timed_out, canceled; anything else means keep polling. A failed run is returned with its failure_reason, not thrown.

• skyvern_cancel_run(run_id) — stop a queued or running run to stop per-step billing.

Typical flow: skyvern_run_task with a url and a data_extraction_schema; if finished is false, call skyvern_get_run with the run_id until it is true. Runs take seconds to minutes.

Auth

BYO only. Pass your Skyvern API key as _apiKey. Every run is billed to your Skyvern account per browser step; max_steps defaults to 25 to bound that. Without a key every tool refuses with "requires an API key" and makes no upstream call.

Data sources

• Skyvern, browser automation service — the run is executed by Skyvern in its own browsers against whatever site you point it at. What comes back is whatever that site shows; the pack adds no data of its own. The site's terms and any login are your responsibility, as are the credentials you put in a prompt.

Notes for the next person: completed with a null output is returned with a warning rather than as a clean success. Test fixtures are synthetic documents using the field names of the vendor's published API schema (no key was available at build); the first keyed call after deploy is the real shape check.

Quick Start

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

{
  "mcpServers": {
    "skyvern": {
      "url": "https://gateway.pipeworx.io/skyvern/mcp"
    }
  }
}

What this endpoint actually serves

tools/list at https://gateway.pipeworx.io/skyvern/mcp returns the tools in the table above plus the shared Pipeworx meta-tools — ask_pipeworx, discover_tools, search_within, remember/recall and the rest of the gateway-wide set. So the tool count you see is larger than this table: a single-pack endpoint currently lists roughly 30 shared tools alongside the pack's own. The connection's initialize response states its exact scope, and is the authoritative answer for a given day.

This is deliberate, not multiplexing by accident. The meta-tools are what let a scoped connection answer a question this pack does not cover — via ask_pipeworx, which routes across the whole catalog — without you adding a second MCP server. There is currently no way to mount a pack endpoint without them; if the extra schemas cost you more context than the routing is worth, connect to the full gateway once rather than to several pack endpoints.

Or connect to the full Pipeworx gateway to get every pack's tools listed directly, instead of just this one's:

{
  "mcpServers": {
    "pipeworx": {
      "url": "https://gateway.pipeworx.io/mcp"
    }
  }
}

Both URLs reach the same gateway and the same 1869+ data sources. The only difference is which pack's tools are listed directly; ask_pipeworx reaches all of them from either one.

No MCP client? Call it over HTTP

This pack takes your own API key (_apiKey) — we don't front one for it, so there's no curl here that would run without it. Inspect any tool: GET https://gateway.pipeworx.io/v1/tools/skyvern_run_task. Find one: POST https://gateway.pipeworx.io/v1/tools/search_packs with {"query":"..."}.

Run it from npm

@pipeworx/mcp-skyvern is a local stdio bridge to the Pipeworx gateway: your MCP client starts it with npx, and it forwards every call to the same https://gateway.pipeworx.io/skyvern/mcp endpoint shown above. It needs network access; there is no offline mode.

{
  "mcpServers": {
    "skyvern": {
      "command": "npx",
      "args": ["-y", "@pipeworx/mcp-skyvern"]
    }
  }
}

Without a key it calls anonymously, capped at 50 calls a day. A free account raises that to 200 a day: get a key at https://pipeworx.io/signup and add "env": { "PIPEWORX_API_KEY": "<your key>" } to the server entry. The key is sent as a Bearer token, the same way a hosted connection sends it, so calls are metered and billed exactly as they are there.

It lists only this pack's tools by default. Set PIPEWORX_META_TOOLS=1 to also list ask_pipeworx and the other gateway-wide tools.

Behind an HTTPS proxy: Node's built-in fetch does not read HTTPS_PROXY by default. Newer Node releases honour it when NODE_USE_ENV_PROXY=1 is set; check your Node version's documentation.

Using with ask_pipeworx

Instead of calling tools directly, you can ask questions in plain English — this works on the pack endpoint above as well as on the full gateway:

ask_pipeworx({ question: "your question about Skyvern data" })

The gateway picks the right tool and fills the arguments automatically.
