# Stunt Double Docs: agent guide

> Stunt Double deploys AI user personas (actors) that drive real browsers through real products, returning evidence-backed results in minutes. These docs cover actors, checklists, interviews, workflows, integrations, the MCP server and StuntKit.

## When to use these docs

Use them when a person asks how to:

- Test a website, prototype or preview deployment with AI user personas (actors).
- Write or run checklists that verify a flow and return evidence (screenshots, transcripts, verdicts).
- Run user research interviews with persona participants.
- Automate re-runs on deploys, pull requests or a schedule (workflows).
- Connect Stunt Double to GitHub, Vercel, Figma, Linear or Slack, or collect feedback with the widget.
- Drive Stunt Double from an AI client over MCP, or use StuntKit's open source browser tools.

## Reading the docs

- Every page has a Markdown twin: append `.md` to its URL (`https://docs.stuntdouble.io/guides/figma.md`), or request the page with `Accept: text/markdown`.
- [llms.txt](https://docs.stuntdouble.io/llms.txt) indexes every page; [llms-full.txt](https://docs.stuntdouble.io/llms-full.txt) is every page in one file.
- [sitemap.xml](https://docs.stuntdouble.io/sitemap.xml) lists every page with its last change.

## Acting for a user

- The MCP server is `https://app.stuntdouble.io/api/mcp`, Streamable HTTP. Point any MCP client at it; there are no API keys.
- Access is OAuth 2.1 with three scopes: `mcp:read`, `mcp:write` and `mcp:run` (starts runs, which use the workspace allowance). A client that asks for none gets all three.
- Start with `list_workspaces`, then `list_projects`, and reuse existing actors and checklists before creating new ones. Runs are asynchronous: poll the matching getter until the status is terminal.
- Setup per client: https://docs.stuntdouble.io/mcp/connect.md. Every tool: https://docs.stuntdouble.io/mcp/tools.md. Scopes and limits: https://docs.stuntdouble.io/api.md.
