Vibe MCP - Browser Automation for AI Agents

MCP server for Vibe AI Browser — drive your real, logged-in Chrome from any MCP client, including agents running on a different machine with no inbound port open.

⚠️ Security — treat your relay URL/UUID like a password. A relay URL or extension UUID (wss://relay.api.vibebrowser.app/<uuid>) grants live control of your browser session (read your tabs, take screenshots, read page content). Never share it, paste it into a chat with untrusted parties, or commit it to a repo. Every example UUID in this documentation is a non-routable placeholder (YOUR-EXTENSION-UUID or 00000000-0000-0000-0000-000000000000) — substitute your own secret value locally and keep it out of version control.

Install prompt for AI agents (OpenClaw / Hermes)

Paste the block below into your OpenClaw or Hermes agent. Replace the last line with your remote value — a UUID or a wss://relay.api.vibebrowser.app/<uuid> URL from the Vibe extension's Settings → AI Agent Control → Remote (internet) → Relay access. That's the only edit you make.

You are setting yourself up to control my real Chrome through Vibe Browser. Work through the steps in order, and after each step confirm it worked before moving on. Do not claim a step is done until you have proven it.

1. Install the "vibebrowser" skill for your runtime:
   - OpenClaw:  npx -y skills add VibeTechnologies/vibe-mcp -s vibebrowser -a openclaw -g -y --copy --dangerously-accept-openclaw-risks
                then run `openclaw skills list` and confirm a "vibebrowser" row shows "ready" as installer registration.
   - Hermes:    npx -y skills add VibeTechnologies/vibe-mcp -s vibebrowser -y
                optional installer registration check: `npx -y skills list` shows a "vibebrowser" row.

2. Remember my remote so I only give it to you once. Save it to a file `vibebrowser-cli.md` in your persistent agent workspace root (the directory that holds your `memory/` folder — not the shell's working dir, not $HOME unless they are the same) as a line `remote: <value>`; if your runtime can also write memory keys, additionally store it under `vibebrowser_remote`. On every later command — including the first message of a new conversation — load it back from that file and reuse it without asking me again.

3. Record a standing rule so you route correctly later: whenever I ask you to do anything in MY browser / MY Chrome / MY tabs / the page I'm on, use this vibebrowser skill (`npx -y @vibebrowser/cli@latest` with my saved remote) to drive my REAL browser — never your built-in, headless, or in-pod browser, never web-fetch instead, and never run `vibebrowser`. Save this rule wherever your standing instructions/memory live so it applies in future conversations.

4. Confirm you can control my Chrome, retrying on "Extension reconnecting" (wait 3s, up to 5x):
   npx -y @vibebrowser/cli@latest --remote "<my remote>" --json status --wait-for-extension --wait-timeout 20000
   npx -y @vibebrowser/cli@latest --remote "<my remote>" --json snapshot --format aria

Then report: (1) is extensionConnected true, (2) did the snapshot return my real page content?

My remote: <PASTE YOUR UUID OR wss:// URL HERE>

Why Vibe MCP?

The browser-automation MCP space moved fast. Most of what used to differentiate us is now table stakes — so here is an honest scorecard. Where a competitor matches us, the column says Yes.

Capability	Vibe MCP	Playwright MCP	Chrome DevTools MCP	Claude for Chrome	BrowserMCP
Uses your real profile / logged-in sessions	Yes	Yes (--extension)	Yes (own --user-data-dir)	Yes	Yes
No per-connection approval dialog	Yes	Yes (token)	Yes (dedicated profile only)	Yes	Yes
Real logged-in profile and no dialog, together	Yes	Yes	No — pick one	Yes	Yes
Multiple agents against one browser	Yes	Yes (--shared-browser-context)	Yes (--experimentalPageIdRouting)	No	No
Agent on another machine, no inbound port	Yes — extension dials out to a relay	No	No — needs an inbound debug port + forwarding	No	No
Works with any MCP client (Codex, OpenCode, Cursor, Hermes, OpenClaw)	Yes	Yes	Yes	No — Anthropic surfaces only	Yes

Two rows are ours alone:

• Outbound, cross-machine control. The Vibe extension opens an outbound WebSocket to a relay (wss://relay.api.vibebrowser.app/<uuid>). Nothing listens on the user's machine, nothing is port-forwarded, and the agent can live in a pod, a cron job, or a chat bot. No competitor documents an extension-initiated outbound connection to a remote MCP server.
• Real profile without the dialog tax. Chrome DevTools MCP needs approval for each WebSocket connection to Chrome (#1794, open; persistence was closed won't-fix). The maintainer's workaround — --remote-debugging-port with a dedicated --user-data-dir — avoids the dialog by giving up your logged-in profile. So: skip the dialog, or use your real profile — not both.

Also worth knowing:

• Vendor lock-in. Claude for Chrome is GA, clicks and types via the debugger permission, and supports scheduled tasks — it is the closest competitor. But it only drives Anthropic's own surfaces (side panel, Claude Desktop connector, Cowork, Claude Code). There is no public API or MCP surface, so Codex, OpenCode, Hermes and OpenClaw cannot use it. Vibe MCP is agent-agnostic.
• Stability. Chrome DevTools MCP is explicitly experimental and currently carries open memory-leak (#2431, #2291, #2456) and concurrency (#1763, #1921) issues.

Multi-Agent Architecture

Run Claude Desktop, Cursor, VS Code Copilot, and OpenCode at once — they share control of one browser through the relay, which multiplexes requests and routes each response back to the agent that asked.

Features

• Multi-Agent Ready - Run Claude, Cursor, VS Code, and more simultaneously against one browser
• Uses Your Browser - No separate browser instance, uses your existing Chrome with all your logins
• Remote-capable - The extension dials out to a relay, so the agent can run on another machine with no inbound port
• Local by default - In local mode everything stays on 127.0.0.1; only remote relay mode routes traffic through relay.api.vibebrowser.app
• Direct Chrome DevTools mode - Extension tools stay primary by default; use --devtools to drive your real running Chrome directly over the DevTools Protocol (no extension required)

Quick Start

1. Install the Vibe Extension

Install the Vibe AI Browser extension in Chrome, Brave, or any Chromium browser:

Option A: Chrome Web Store (Recommended)

• Visit the Chrome Web Store
• Click "Add to Chrome"
• The Vibe icon will appear in your toolbar

Option B: Developer Version

• Download the latest release ZIP
• Extract to a permanent folder
• Go to chrome://extensions, enable Developer Mode
• Click "Load unpacked" and select the extracted folder

For detailed instructions, see the installation guide.

2. Configure Your AI Application

Claude Desktop

Edit your Claude Desktop config file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json

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

Restart Claude Desktop after saving.

Cursor

• Open Cursor Settings (Cmd/Ctrl + ,)
• Go to "Features" -> "MCP Servers"
• Click "Add Server" and add:

{
  "vibe": {
    "command": "npx",
    "args": ["-y", "@vibebrowser/mcp"]
  }
}

Or edit ~/.cursor/mcp.json directly.

VS Code (GitHub Copilot)

Add to your VS Code settings.json:

{
  "github.copilot.chat.mcpServers": {
    "vibe": {
      "command": "npx",
      "args": ["-y", "@vibebrowser/mcp"]
    }
  }
}

Windsurf

Edit ~/.codeium/windsurf/mcp_config.json:

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

OpenCode

Add to your .opencode/config.json:

{
  "mcp": {
    "servers": {
      "vibe": {
        "command": "npx",
        "args": ["-y", "@vibebrowser/mcp"]
      }
    }
  }
}

Gemini CLI

Add to ~/.gemini/settings.json:

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

OpenAI Codex CLI

Add to your Codex configuration:

{
  "mcp": {
    "vibe": {
      "command": "npx",
      "args": ["-y", "@vibebrowser/mcp"]
    }
  }
}

MCP command forms

Use the shortest direct package invocation for the MCP server:

npx -y @vibebrowser/mcp@latest --help
npx -y @vibebrowser/mcp@latest start --transport http
npx -y @vibebrowser/mcp@latest openclaw --remote "$VIBE_REMOTE_UUID"

Backward-compatible aliases still work when you need explicit binaries:

npx -y -p @vibebrowser/mcp@latest vibebrowser-mcp --help
npx -y -p @vibebrowser/mcp@latest vibe-mcp --help

3. Connect the Extension

• Open Chrome with the Vibe extension installed
• Click the Vibe extension icon in the toolbar
• Go to Settings and enable "MCP External Control"
• The status should show "Connected"

If the extension is not connected, vibebrowser-mcp can optionally fall back to chrome-devtools-mcp (started in --autoConnect mode) when that package is installed. This fallback runs once in the shared local relay daemon (multi-agent safe), so both vibebrowser-mcp and vibebrowser-cli use the same backend instance. When extension is connected, extension tools are authoritative.

--devtools mode (drive your real Chrome over CDP)

Pass --devtools to either CLI to bypass relay/extension routing entirely and drive your real running Chrome directly over the Chrome DevTools Protocol. This backend (ported from the chrome-use skill) reads Chrome's DevToolsActivePort file and autoConnects to your live profile — no extension, no external MCP server, zero extra dependencies. Requires Chrome 144+; the permission dialog fires once per profile.

--devtools exposes a focused tool set: navigate, snapshot (accessibility tree with @eN refs), click, fill, type, press_key, hover, scroll, screenshot, eval, get_text, get_url, get_title, and tab management (list_tabs, new_tab, select_tab, close_tab). Use snapshot to get @eN element refs, then pass them as selectors to click/fill/type.

Override the Chrome profile/channel with VIBE_CHROME_USER_DATA_DIR and VIBE_CHROME_CHANNEL (stable | canary | beta | dev).

Not yet covered by --devtools v1 (addable later as more CDP domains are wired): network request inspection, console logs, performance traces, Lighthouse, memory snapshots, device emulation, dialog handling, file upload, and drag.

How It Works

Default local mode (no flags):

Claude / Cursor / VS Code (stdio)
            │
            ▼
   [vibebrowser-mcp]
            │  ws://127.0.0.1:19888
            ▼
     Local Relay (auto-spawned)
            │  ws://127.0.0.1:19889
            ▼
     Vibe Extension (Chrome)

• AI applications connect via MCP over stdio
• vibebrowser-mcp connects to the local relay on port 19888
• The relay forwards commands to the extension on port 19889
• Results flow back to the agent

Two legs, two protocols

Don't conflate them — the transport to the MCP server is configurable, the transport to the extension is not.

Leg	Protocol	Configurable?
MCP client → vibebrowser-mcp	stdio or streamable HTTP	Yes — --transport stdio|http
vibebrowser-mcp ↔ relay ↔ extension	WebSocket only	No

MCP client ──stdio──┐
                    ├──> [vibebrowser-mcp] ──ws──> [relay] ──ws──> [extension]
MCP client ──http───┘

Streamable HTTP lets a remote or hosted agent — one that can't spawn a stdio subprocess — talk to the server over a URL:

npx -y @vibebrowser/mcp@latest start --transport http
# serves POST/GET http://127.0.0.1:8788/mcp

Defaults: --host 127.0.0.1, --http-port 8788, --http-path /mcp. Add --allow-host <host> (repeatable) if you front it with a proxy or bind it beyond localhost.

Multi-Agent Mode

When multiple agents connect, Vibe MCP automatically spawns a relay daemon:

• First agent starts the relay (listens on ports 19888 and 19889)
• Additional agents connect to the relay as clients
• Relay multiplexes all agent requests to the single extension connection
• Each agent receives only its own responses

Cloud OpenClaw -> Local Browser

⚠️ Security: The --remote value below is a live credential — a relay URL/UUID grants full control of the target browser session. It is the sole bearer credential (there is no second-factor token). Treat it like a password: keep it secret, never commit it or paste it into logs, and if it leaks, regenerate it in the Vibe extension Settings.

If your agent runs in the cloud but you want it to control the user's real local browser, run vibebrowser-mcp in HTTP mode and connect it to the Vibe extension in remote relay mode. Pass either the extension UUID or the full WebSocket relay URL to --remote.

VIBE_REMOTE_UUID="YOUR-EXTENSION-UUID"
VIBE_REMOTE_URL="wss://relay.api.vibebrowser.app/YOUR-EXTENSION-UUID"
npx -y @vibebrowser/mcp@latest start --transport http --remote "$VIBE_REMOTE_UUID"
npx -y @vibebrowser/mcp@latest start --transport http --remote "$VIBE_REMOTE_URL"

This exposes a local MCP endpoint at http://127.0.0.1:8788/mcp by default.

When OpenClaw runs on a different machine (for example cloud-hosted), provide a reachable URL:

VIBE_REMOTE_UUID="YOUR-EXTENSION-UUID"
VIBE_REMOTE_URL="wss://relay.api.vibebrowser.app/YOUR-EXTENSION-UUID"
PUBLIC_MCP_URL="https://browser-bridge.example.com/mcp"
npx -y @vibebrowser/mcp@latest openclaw --remote "$VIBE_REMOTE_UUID" --public-url "$PUBLIC_MCP_URL"
npx -y @vibebrowser/mcp@latest openclaw --remote "$VIBE_REMOTE_URL" --public-url "$PUBLIC_MCP_URL"

You can print the exact OpenClaw-friendly setup with:

VIBE_REMOTE_UUID="YOUR-EXTENSION-UUID"
VIBE_REMOTE_URL="wss://relay.api.vibebrowser.app/YOUR-EXTENSION-UUID"
npx -y @vibebrowser/mcp@latest openclaw --remote "$VIBE_REMOTE_UUID"
npx -y @vibebrowser/mcp@latest openclaw --remote "$VIBE_REMOTE_URL"

Use --remote <uuid> with the default public relay, or --remote <full-ws-url> when you need an explicit relay endpoint. The UUID is the only credential — never share it, log it, or paste it into an untrusted chat.

For direct browser CLI checks, always use npx -y @vibebrowser/cli@latest:

VIBE_REMOTE_UUID="YOUR-EXTENSION-UUID"
VIBE_REMOTE_URL="wss://relay.api.vibebrowser.app/YOUR-EXTENSION-UUID"
npx -y @vibebrowser/cli@latest --remote "$VIBE_REMOTE_UUID" --json status
npx -y @vibebrowser/cli@latest --remote "$VIBE_REMOTE_URL" --json status

--remote <uuid> uses the default public relay. --remote <full-ws-url> targets an explicit relay endpoint. No second-factor secret is needed or accepted — the UUID alone authorizes the session.

For the full walkthrough, see docs/openclaw-local-browser.md.

OpenClaw-Compatible Browser CLI

npx -y @vibebrowser/cli@latest mirrors the OpenClaw browser CLI shape for the real local-browser path:

npx -y @vibebrowser/cli@latest sessions
VIBE_REMOTE_UUID="YOUR-EXTENSION-UUID"
VIBE_REMOTE_URL="wss://relay.api.vibebrowser.app/YOUR-EXTENSION-UUID"
npx -y @vibebrowser/cli@latest --remote "$VIBE_REMOTE_UUID" status
npx -y @vibebrowser/cli@latest --remote "$VIBE_REMOTE_URL" tabs
npx -y @vibebrowser/cli@latest --remote "$VIBE_REMOTE_UUID" open https://example.com
npx -y @vibebrowser/cli@latest --remote "$VIBE_REMOTE_URL" snapshot
npx -y @vibebrowser/cli@latest --remote "$VIBE_REMOTE_UUID" click 12
npx -y @vibebrowser/cli@latest --remote "$VIBE_REMOTE_URL" type 23 "hello" --submit
npx -y @vibebrowser/cli@latest --devtools status

Use the MCP package for MCP server workflows and the CLI package for direct browser control:

• vibebrowser-mcp for MCP server, HTTP bridge, and helper commands
• npx -y @vibebrowser/cli@latest for OpenClaw-inspired browser control against the real Vibe-connected session

@vibebrowser/cli accepts the OpenClaw-style --browser-profile flag for compatibility and supports --json for machine-readable output. Unlike OpenClaw's managed openclaw browser profile, this CLI always targets the real Vibe-connected browser session.

Local-session selection:

• npx -y @vibebrowser/cli@latest sessions lists connected local browser sessions.
• npx -y @vibebrowser/cli@latest --session <id> ... targets a specific local session.
• If --session is omitted in local mode, the CLI uses the first connected session.
• In remote mode, pass either --remote <uuid> to use the default public relay or --remote <full-ws-url> to use an explicit relay endpoint.

Snapshot behavior is tool-only (no legacy snapshot RPC shortcut):

• snapshot (default, --format ai) resolves via the take_md_snapshot tool — uses the content script's in-page markdown extractor. Fast and readable, but may return empty for background tabs or complex SPAs (Notion, Gmail) where the content script is unreachable or layout is not computed.
• snapshot --format aria resolves via the take_a11y_snapshot tool — uses Chrome DevTools Protocol Accessibility.getFullAXTree directly. Reliable for all tabs including background tabs and SPAs. Use this as a fallback when the default format returns empty or only a page title.

This keeps CLI behavior aligned with extension-supported tools and ensures page targeting works consistently with --page-id/--pageId.

For navigation-style operations, responses now include page content when page state changes:

• CLI open / navigate include pageContent in JSON output.
• MCP tool calls for navigation-style tools return text content that includes current page state (with snapshot fallback when needed).

Install Prompt for AI Agents (OpenClaw / Hermes)

Use the single canonical copy-paste prompt at the top of this README: Install prompt for AI agents (OpenClaw / Hermes). It installs the vibebrowser skill, saves your remote so you only give it once, and proves control of your real Chrome.

For a deeper skill definition (when to prefer this over a managed/headless browser, the remote-recall rules, selector/snapshot guidance), install openclaw/vibebrowser/SKILL.md into the agent's skills directory.

OpenClaw Integration

There are two ways to use Vibe with OpenClaw:

Option A: Cloud OpenClaw controlling local browser

If OpenClaw runs in the cloud but you want it to control your local browser:

• Install the Vibe extension and enable Remote mode (see docs/openclaw-local-browser.md)
• Start the local HTTP bridge: vibebrowser-mcp openclaw --remote "$VIBE_REMOTE_UUID" [--public-url "$PUBLIC_MCP_URL"] or vibebrowser-mcp openclaw --remote "$VIBE_REMOTE_URL" [--public-url "$PUBLIC_MCP_URL"]
• Register the MCP URL in OpenClaw

Option B: OpenClaw skill for local agents

For OpenClaw agents that need your real browser context (logged-in sessions, existing tabs):

• Copy the Vibe skill from this package to your OpenClaw skills folder
• Use the extension UUID or full WebSocket relay URL with --remote
• Use npx -y @vibebrowser/cli@latest commands in your agent prompts

The skill is located at openclaw/vibebrowser/SKILL.md and provides:

• Full OpenClaw-compatible CLI commands (status, tabs, snapshot, click, type, etc.)
• Fallback-safe commands for DevTools-backed flows (resize, upload, dialog)
• --json output for machine parsing
• Environment-based configuration

See docs/openclaw-local-browser.md for the complete walkthrough.

Local LLM: serve Command

Run a local LLM with one command — no cloud API keys required. Automatically installs Ollama, downloads the model, and starts serving an OpenAI-compatible API.

npx -y @vibebrowser/mcp@latest serve qwen3.5

That's it. Works on macOS, Linux, and Windows.

What it does

• Detects Ollama → installs it if missing (via brew, curl, or winget)
• Starts the server → launches ollama serve in the background
• Downloads the model → streams download progress to your terminal
• Prints connection info → ready to use with VibeBrowser or any OpenAI-compatible client

Recommended models

npx -y @vibebrowser/mcp@latest serve qwen3.5      # Best overall for agentic tasks
npx -y @vibebrowser/mcp@latest serve llama4        # Strong general reasoning
npx -y @vibebrowser/mcp@latest serve deepseek-r1   # Reasoning chains
npx -y @vibebrowser/mcp@latest serve mistral       # Lightweight & fast (7B)

Options

npx -y @vibebrowser/mcp@latest serve <model> [options]

Options:
  -p, --port <number>  Ollama API port (default: 11434)
  -y, --yes            Skip install confirmation prompts
  -d, --debug          Enable debug logging

Using with VibeBrowser extension

After serve completes, configure the extension:

• Model provider → ollama
• Model name → the model you served (e.g., qwen3.5)

The extension connects to http://localhost:11434/v1 automatically.

CLI Options

npx -y @vibebrowser/mcp@latest --help
npx -y @vibebrowser/cli@latest --help

# MCP server (default)
npx -y @vibebrowser/mcp@latest [start] [options]
  -p, --port <number>  WebSocket port for local relay (agent) connection (default: 19888)
  -d, --debug          Enable debug logging
  --transport <mode>   MCP transport to expose: stdio or http (default: stdio)
  --host <host>        Host to bind the HTTP server to (default: 127.0.0.1)
  --http-port <number> Port for streamable HTTP MCP transport (default: 8788)
  --http-path <path>   Path for streamable HTTP MCP transport (default: /mcp)
  --allow-host <host>  Allowed host header for HTTP transport (repeatable)
  -r, --remote <uuid-or-url>  Extension UUID, or full ws(s) remote URL. This routing UUID is the sole bearer credential — treat it like a password.
  --devtools           Drive your real running Chrome directly over the DevTools Protocol (bypasses the extension relay)

# MCP server tool
set_remote { "url": "wss://relay.api.vibebrowser.app/<extension-uuid>" }

The set_remote MCP server tool hot-reconnects the running MCP server to a different remote relay URL. It is an MCP tool, not a browser CLI subcommand. The URL's UUID is the only credential — never place it in logs shared with untrusted parties; regenerate it in extension Settings if exposed.

  -d, --debug          Enable debug logging

Troubleshooting

"No connection to Vibe extension"

• Ensure the Vibe extension is installed in Chrome
• Click the extension icon and enable "MCP External Control" in Settings
• Check that no firewall is blocking localhost connections

"OpenClaw cannot reach my local browser bridge"

• Start vibebrowser-mcp in HTTP mode instead of stdio
• Make sure the bridge process is still running on the user's machine
• Confirm the extension is in Remote mode and connected
• Verify the MCP URL in OpenClaw matches the bridge URL. If OpenClaw is cloud-hosted, do not use 127.0.0.1; use openclaw --public-url with a reachable host.

Debug mode

Enable debug logging to diagnose issues:

{
  "mcpServers": {
    "vibe": {
      "command": "npx",
      "args": ["-y", "@vibebrowser/mcp", "--debug"]
    }
  }
}
