Vibe MCP — Real Chrome, Remotely

Vibe MCP - Browser Automation for AI Agents

[npm version] [License]

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.

Privacy

Privacy policy: https://vibebrowser.app/privacy — what the extension, the local MCP server, and the hosted relay collect, log, and retain, including the relay's security audit records and how to revoke a connection URL.

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 — the connector URL (https://relay.api.vibebrowser.app/mcp/<uuid>) shown in the Vibe extension's Settings → AI Agent Control → Remote (internet) → Relay access (a bare UUID or a wss:// relay URL also still work). 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 CONNECTOR URL, 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.

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.

Claude Desktop       Cursor          VS Code         OpenCode     |                  |                |               |     v                  v                v               v [vibebrowser-mcp] [vibebrowser-mcp] [vibebrowser-mcp] [vibebrowser-mcp]     |                  |                |               |     +------------------+----------------+---------------+                        |                        v                  [Relay Daemon]  <-- Auto-spawned, handles multiplexing                        |                        v                 [Vibe Extension]                        |                        v                   [Your Chrome]

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)

1. Visit the Chrome Web Store
2. Click "Add to Chrome"
3. The Vibe icon will appear in your toolbar

Option B: Developer Version

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

For detailed instructions, see the installation guide.

2. Configure Your AI Application

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

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

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

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

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

codex mcp add vibe -- npx -y @vibebrowser/mcp

[mcp_servers.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 --helpnpx -y @vibebrowser/mcp@latest start --transport httpnpx -y @vibebrowser/mcp@latest openclaw --remote "$VIBE_REMOTE_URL"

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

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

Remote connector (hosted assistants — no install)

Everything above assumes the client can spawn a local process. Hosted assistants cannot: Claude on the web / in Cowork / on mobile, and ChatGPT on the web, run in the vendor's cloud with no access to your machine. They accept a remote MCP server URL and nothing else — no command, no arguments, and no custom request headers.

For those, skip @vibebrowser/mcp entirely. The extension alone is enough:

https://relay.api.vibebrowser.app/mcp/<your-extension-uuid>

Find <your-extension-uuid> in the extension: Vibe icon → Settings → AI Agent Control → Remote (internet) → Relay access. That panel shows this exact connector URL, and the same string is now the preferred value for the CLI/server --remote flag — paste it in both places, no translation needed:

VIBE_REMOTE_URL="https://relay.api.vibebrowser.app/mcp/00000000-0000-0000-0000-000000000000"npx -y @vibebrowser/mcp@latest start --remote "$VIBE_REMOTE_URL"

A bare extension UUID or a wss://relay.api.vibebrowser.app/<uuid> relay URL are still accepted as advanced/compatibility forms — see the accepted --remote values table in "Cloud OpenClaw -> Local Browser" below.

This is a plain Streamable HTTP MCP endpoint. There is no OAuth consent flow, no dynamic client registration, and no scope setup on this path — the UUID in the URL (or header, below) is the entire credential. If a client insists on an OAuth login before it will add the server, that client is not supported here; use the local stdio path instead.

Where to paste it:

Custom connectors are a paid-plan feature in the Claude and ChatGPT products.

Codex Desktop, Codex CLI and the Codex IDE extension can spawn a local process, and they all share ~/.codex/config.toml. Prefer the local stdio entry above — it keeps traffic on 127.0.0.1 and keeps the UUID out of a URL. Use codex mcp add vibe --url … only when the browser you want to drive is on a different machine from Codex. The ChatGPT desktop app is Codex-backed and reads the same config, so it is a local-stdio surface too; only ChatGPT web needs the hosted URL.

Migrating away from the retired OAuth-style connector guidance

Earlier drafts of these docs (and the Aug 2026 directory-submission research kept under worklog/) described a retired OAuth 2.1 + DCR consent flow at a bare /mcp. That path is retired and unsupported for users. If you previously added Vibe as a connector and were sent to a retired consent screen, remove that connector and re-add it with the direct https://relay.api.vibebrowser.app/mcp/<uuid> URL above. Nothing to authorize, nothing to register, no scopes to pick.

The relay also accepts the UUID as an X-Remote-Session or Authorization: Bearer header on a bare POST /mcp. Use the header form from anything that can send one (Codex CLI, scripts) — it keeps the credential out of URLs, logs, and browser history. The path form exists specifically for the UIs that cannot send a header.

Two things this path costs you, stated plainly:

1. The URL is a credential. Anyone who has that UUID can drive your logged-in browser — read your mail, act as you on any site you are signed into. Treat it exactly like a password: never commit it, never paste it into a shared chat, an issue, a README, or a screenshot. If it leaks, revoke the session in the extension and generate a new one. (This is not hypothetical: a dev machine's UUID once shipped in these very docs.)
2. Page content leaves your machine. On the local STDIO path, tool calls and page content never leave 127.0.0.1. On the remote-connector path they traverse relay.api.vibebrowser.app, because the assistant is in the vendor's cloud and has no other route to your browser. If you need on-device-only, use a desktop client with the local server instead.

3. Connect the Extension

1. Open Chrome with the Vibe extension installed
2. Click the Vibe extension icon in the toolbar
3. Go to Settings and enable "MCP External Control"
4. 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.

Available Tools

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)

1. AI applications connect via MCP over stdio
2. vibebrowser-mcp connects to the local relay on port 19888
3. The relay forwards commands to the extension on port 19889
4. 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.

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/connector URL 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.

Accepted --remote values

--remote (and the MCP set_remote tool) accept three forms, all normalized to the same relay connection:

Self-hosted or local relays derive the same way: https://your-host/vibe/mcp/<uuid> → relay wss://your-host/vibe; a loopback connector like http://127.0.0.1:19889/mcp/<uuid> → ws://127.0.0.1:19889 (self-hosted/local relay only — non-loopback hosts must use https:///wss://).

Rejected: an invalid UUID; a URL with embedded credentials, a query string, or a fragment; plaintext http:///ws:// for a non-loopback host; and any HTTP(S) URL that doesn't end in the exact /mcp/<uuid> suffix.

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 the connector URL (preferred), the extension UUID, or the full WebSocket relay URL to --remote.

VIBE_REMOTE_URL="https://relay.api.vibebrowser.app/mcp/00000000-0000-0000-0000-000000000000"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_URL="https://relay.api.vibebrowser.app/mcp/00000000-0000-0000-0000-000000000000"PUBLIC_MCP_URL="https://browser-bridge.example.com/mcp"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_URL="https://relay.api.vibebrowser.app/mcp/00000000-0000-0000-0000-000000000000"npx -y @vibebrowser/mcp@latest openclaw --remote "$VIBE_REMOTE_URL"

Use the connector URL (preferred) with the default public relay, a bare UUID (default public relay), or a wss:// URL when you need an explicit relay endpoint. Whichever form you use 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_URL="https://relay.api.vibebrowser.app/mcp/00000000-0000-0000-0000-000000000000"npx -y @vibebrowser/cli@latest --remote "$VIBE_REMOTE_URL" --json status

The connector URL uses the default public relay. --remote <uuid> also uses the default public relay. --remote <full-ws-url> targets an explicit relay endpoint. No second-factor secret is needed or accepted — whichever form you pass is the sole credential that 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 sessionsVIBE_REMOTE_URL="https://relay.api.vibebrowser.app/mcp/00000000-0000-0000-0000-000000000000"npx -y @vibebrowser/cli@latest --remote "$VIBE_REMOTE_URL" statusnpx -y @vibebrowser/cli@latest --remote "$VIBE_REMOTE_URL" tabsnpx -y @vibebrowser/cli@latest --remote "$VIBE_REMOTE_URL" open https://example.comnpx -y @vibebrowser/cli@latest --remote "$VIBE_REMOTE_URL" snapshotnpx -y @vibebrowser/cli@latest --remote "$VIBE_REMOTE_URL" click 12npx -y @vibebrowser/cli@latest --remote "$VIBE_REMOTE_URL" type 23 "hello" --submitnpx -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 the connector URL (preferred), a bare --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 markdown; legacy alias --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. When the backend only exposes take_snapshot, the CLI sends format: "markdown" (ai is mapped to markdown before the call).
• 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:

1. Install the Vibe extension and enable Remote mode (see docs/openclaw-local-browser.md)
2. Start the local HTTP bridge: vibebrowser-mcp openclaw --remote "$VIBE_REMOTE_URL" [--public-url "$PUBLIC_MCP_URL"]
3. 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):

1. Copy the Vibe skill from this package to your OpenClaw skills folder
2. Use the connector URL (preferred), the extension UUID, or full WebSocket relay URL with --remote
3. 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

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

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.

The set_remote MCP server tool hot-reconnects the running MCP server to a different remote relay. It is an MCP tool, not a browser CLI subcommand. It accepts the same three forms as --remote (connector URL preferred, bare UUID, or wss:// URL). The value is the only credential — never place it in logs shared with untrusted parties; regenerate it in extension Settings if exposed.

Troubleshooting

"No connection to Vibe extension"

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

"OpenClaw cannot reach my local browser bridge"

1. Start vibebrowser-mcp in HTTP mode instead of stdio
2. Make sure the bridge process is still running on the user's machine
3. Confirm the extension is in Remote mode and connected
4. 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.
