Tap · leonting1010 — Claude Code MCP server: what it does, how to install
Tap lets an agent perform tasks in your signed-in Chrome and save the interaction as a replayable flow. Use it for pages that require a login.
claude mcp add --transport http tap https://mcp.taprun.dev/mcpWhat Tap does
Tap connects an agent to a Chrome session that is already signed in. The agent inspects a page once and produces a .flow.json program; later runs replay that program without another LLM call. Execution can use the Chrome extension or Playwright.
The server includes tap verify, which compares a page snapshot and reports changes that may break a saved flow. Open pages and APIs can run without the extension, while --no-extension uses a separate Playwright profile. The Chrome extension is required when Tap must reuse a live signed-in session, so its cookies and login remain available to the browser action.
What it helps with
- perform an action on a login-gated page
- save browser steps as a
.flow.jsonprogram - replay a flow without another LLM call
- check a page for changes with
tap verify
Example prompts for the agent
- Open the signed-in site and perform the action I need to repeat.
- Save this browser process as a replayable flow.
- Run
tap verifyon the saved flow and show what changed.
