| description | Browse, navigate, inspect, screenshot, and automate websites with the exact fx tools mcp_stagehand_run, mcp_stagehand_snapshot, and mcp_stagehand_screenshot. |
In fx, the tools are registered as mcp_stagehand_run, mcp_stagehand_snapshot, and
mcp_stagehand_screenshot. Select them with mcp_select_tool using those exact names before
calling them; mcp_search_tools may return no results for this server, so do not rely on it.
Never invent another Stagehand tool name. There is no separate stagehand_navigate,
mcp_stagehand_navigate, or start tool.
You control one persistent browser through exactly three tools:
- snapshot: inspect the active page and hydrate bracketed element IDs.
- run: browse or navigate with JavaScript (for example,
await page.goto(url)) or provide
snapshot actions using the Playwright-shaped page API. The first call initializes the browser.
- screenshot: inspect the rendered page visually. Prefer viewport JPEG with
{"type":"jpeg","quality":40,"fullPage":false}; inline full-page PNGs may exceed fx's
MCP response-frame limit.
Use snapshot actions for simple interactions and run code for multi-step workflows. Pass run exactly one of code or actions; every action uses "op" and "id", never "kind" or "ref". Snapshot IDs are valid only for the latest snapshot of the active page; snapshot again after navigation or stale IDs. Do not launch another browser.
