MCP server for VibeCheck — connect AI assistants (Claude Code, Claude Desktop, Cursor, Windsurf, VS Code) to your bug reports, and let them record their own browser sessions as shareable bug reports.

📖 Full guide — features, installation, use cases → DOCS.md

🎬 Record browser sessions (new)

Give your AI agent a task in plain English — it drives a real browser on your machine while VibeCheck records everything, then returns a shareable link:

You:   Go to staging.myapp.com/cart, add a product and check the total
       updates. Record it and send me the link.

Agent: ⏺ Opening browser — recording started
       ⏺ Clicked: Add to cart
       ⏺ Validated: total updated to $42.00 ✓

       Recording uploaded to VibeCheck.
       Shareable link: https://app.vibecheck-qa.com/tracks/1783…

The link opens a full bug report: video of the session, console logs, network requests (with response bodies), and a labeled action timeline — all synced. Anyone can watch it, no account needed.

• No AI inside — your assistant does the reasoning and clicking; this server is a recorded browser plus an uploader. No extra LLM costs.

• Local browser — works against localhost dev servers and VPN-only staging. Uses your installed Chrome/Edge automatically (fresh isolated profile); auto-downloads a browser if neither exists.

• 11 tools — browser_navigate, browser_snapshot, browser_click, browser_type, browser_press_key, browser_select_option, browser_hover, browser_scroll, browser_screenshot, browser_wait_for, browser_finish (uploads + returns the link).

Perfect for: "go validate this page", reproducing a bug from an existing report, proving a fix before a PR, smoke-testing a deploy.

Installation

Requirements

• Node.js 18+

• A browser — nothing to install if you have Google Chrome or Microsoft Edge (auto-detected). Otherwise one is auto-downloaded on first run (or pre-download: npx playwright install chromium)

• A VibeCheck API key (recording only — the read tools below need no key):

  1. Sign in at app.vibecheck-qa.com

  2. Open the API Keys page (app.vibecheck-qa.com/api-keys) → Generate key

  3. The dialog gives you a ready-made setup: a copy-paste Claude Code command with your key already inside, plus one-click Add to Cursor / Add to VS Code buttons — use those and skip the manual configs below

Claude Code

claude mcp add vibecheck \
  -e VIBECHECK_API_KEY=vck_your_key_here \
  -- npx -y @vibecheck-mcp/mcp

Claude Desktop

Add to claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop:

{
  "mcpServers": {
    "vibecheck": {
      "command": "npx",
      "args": ["-y", "@vibecheck-mcp/mcp"],
      "env": { "VIBECHECK_API_KEY": "vck_your_key_here" }
    }
  }
}

Cursor

Add the same block to .cursor/mcp.json (or use the one-click Add to Cursor button on VibeCheck's API Keys page):

{
  "mcpServers": {
    "vibecheck": {
      "command": "npx",
      "args": ["-y", "@vibecheck-mcp/mcp"],
      "env": { "VIBECHECK_API_KEY": "vck_your_key_here" }
    }
  }
}

Windsurf

Add the same mcpServers block to ~/.codeium/windsurf/mcp_config.json.

VS Code

Add to .vscode/mcp.json (note the key is servers):

{
  "servers": {
    "vibecheck": {
      "command": "npx",
      "args": ["-y", "@vibecheck-mcp/mcp"],
      "env": { "VIBECHECK_API_KEY": "vck_your_key_here" }
    }
  }
}

Verify it works

Open a new session in your AI tool and paste:

Go to https://example.com, then finish the recording titled "Setup test"
and give me the link.

A browser window opens, and within ~15 seconds the agent replies with a .../tracks/... link. If the video plays — you're set. 🎉

Environment variables

Watchable videos

Recordings show a cursor that moves to every element the agent interacts with, a click ripple, and a caption describing each action (Click — Place order button), so anyone watching the video can follow what happened.

If ffmpeg is installed (brew install ffmpeg / apt install ffmpeg), the idle "agent think time" between actions is automatically cut out before upload — a 5-minute session typically becomes under a minute, with the console/network/action timeline re-synced to the shorter video. Without ffmpeg the full-length video is uploaded as-is.

🔍 Analyze bug reports

Paste a VibeCheck track URL and your AI pulls in the full debugging context — no API key needed:

get_track

Fetch and format a complete VibeCheck bug report.

Parameters:

• url_or_id (required) — Track URL or ID

• include (optional) — Sections to include: logs, network, actions, vitals, all

analyze_track_errors

Focused view of errors only — console errors with stack traces and failed network requests with response bodies.

Parameters:

• url_or_id (required) — Track URL or ID

get_track_network

Deep analysis of network requests with failed/slow request detection.

Parameters:

• url_or_id (required) — Track URL or ID

• slow_threshold_ms (optional, default: 1000) — Threshold in ms to flag slow requests

• status_filter (optional, default: all) — Filter: all, errors, success

get_track_performance

Web vitals analysis with ratings and optimization suggestions.

Parameters:

• url_or_id (required) — Track URL or ID

get_track_actions

User action timeline with auto-generated steps to reproduce.

Parameters:

• url_or_id (required) — Track URL or ID

• action_types (optional) — Filter by type: click, input, scroll, navigation, etc.

Screenshot support

For screenshot tracks, get_track and analyze_track_errors return the screenshot image alongside the text report using MCP's ImageContent type. Video tracks return text data only (no video fetch).
