What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Connection: Runs on your computer
Transport: stdio
Category: Other

Install

Pick the AI app you use, then copy the settings.

Before you install

Basic checks: 1 of 1 passed
Runs on your computer with your user’s permissions (files, network, apps).
The registry lists no key to fill in.

You need

npmNode.js installed (for the npx command)

Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

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

Run this in your terminal

claude mcp add weavetab -- npx -y @weavetab/mcp

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

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

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "weavetab": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@weavetab/mcp"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Common questions

Is Weavetab safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (2.5.0) reached the registry 20 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

The open automation engine for AI agents. Control live browsers and desktop apps locally with instant execution.

Tool Reference · Documentation · Architecture · Support · Security

Weavetab is the open automation engine for AI agents. It connects models directly to live Chromium browsers and Electron desktop applications via native Chrome DevTools Protocol (CDP) sockets — no WebDriver binaries, no cloud relay, zero telemetry.

Actions execute directly over local CDP sockets without external driver overhead. Web pages are translated into agent-readable semantic maps with turn-by-turn diffing that reduces token usage by up to 95%. Built-in security enforces local domain policies, role-based access control, and client-side credential injection.

Built and architected by fy2ne.

Why not Playwright or Puppeteer?

The standard approach — Playwright over MCP — works. But it carries fundamental architectural costs that compound at scale.

	Playwright / Puppeteer	Weavetab
Protocol layer	WebDriver BiDi or CDP via browser binary	Direct CDP WebSocket
Tool execution overhead	50–300 ms (binary + IPC overhead)	In-process (direct local socket)
Desktop app control	Browser only	Chrome + any Electron app (Discord, VS Code, Figma…)
DOM representation	Full HTML dump to LLM	Semantic Map 3.0 with delta diffing
Token cost per map	~2,000–8,000 tokens	~80–400 tokens (95% reduction via delta)
CAPTCHA	API service required	Zero-API via CDP mouse physics
Credential safety	Secrets passed in plaintext	Blind Injection — never in LLM context
Extension access	Limited	Full Chrome Extension API surface

Architecture

MCP Client (Claude / Cursor / Antigravity / Copilot / Windsurf)

No cloud. No external process. Both the CDP WebSocket connection and the optional MCP WebSocket daemon (--ws) are strictly bound to 127.0.0.1 with shared-secret authentication (~/.weavetab-system/ws-secret) and Origin/Host header verification.

Quick Start

npx -y @weavetab/mcp

Add to your MCP client config:

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

Client	Config path
Claude Desktop	`~/Library/Application Support/Claude/claude_desktop_config.json`
Claude Code	`claude mcp add weavetab -- npx -y @weavetab/mcp`
Cursor	`.cursor/mcp.json`
Antigravity	`~/.gemini/antigravity/mcp/weavetab/`
VS Code Copilot	`.vscode/mcp.json`
Windsurf	`~/.codeium/windsurf/mcp_config.json`

Core Technology

Semantic Map 3.0

The primary bottleneck in browser-based agents is DOM representation. Full HTML dumps are noisy, large, and structurally meaningless to language models. Weavetab's browser_map runs an in-browser CDP walker that produces a compact semantic map:

╔═ ACTIVE DIALOG: "Confirm Payment" ═╗

[w:3] button "Confirm" [w:4] button "Cancel"

┌ "Pro Plan — $49/mo" [w:12] button "Upgrade" [w:13] button "View Details" [w:14] input val:"john@example.com" ph:"Email address" FOCUSED

[w:20...w:38] 18 nav links: "Dashboard" ... "Sign out"

Key properties:

Ref IDs (w:N) are stable within a session and used by all interaction tools
Container binding — buttons and inputs are grouped under their parent card, row, or section header
Modal hoisting — open dialogs are isolated at the top so agents cannot miss them
Link collapsing — repeated nav/footer runs of 4+ links compress into a single token line
Semantic delta — on re-reads, only changed nodes are transmitted (~ modified, + added, − removed), cutting re-read cost by up to 95%

Ghost Cursor

Clicks are not dispatched as synthetic DOM events. They are delivered as a physical sequence of Input.dispatchMouseEvent CDP calls along a Bezier curve trajectory with randomized acceleration, natural jitter, and hold durations. Anti-bot fingerprinting that flags event-based automation does not trigger.

browser_pointer supports hover_chain for multi-level menu traversal in a single tool call:

"hover_chain": ["File", "Export As", "PNG"], "click_final": true }

Blind Credential Injection

browser_type_secret resolves secrets server-side from ~/.weavetab/secrets.json. The resolved value is never included in the MCP response, never appears in DOM snapshots, and is permanently masked as [REDACTED] in all audit logs. The LLM context never sees the credential.

weavetab secrets set GITHUB_TOKEN

Stored. Never echoed, never logged, never surfaced to the agent.

Electron & Desktop App Automation

Any tool accepts an optional app parameter that routes the command to a registered Electron process instead of a browser tab:

{ "app": "discord", "ref": "w:24", "text": "Hey, deploying now" }

"electron": { "discord": "C:\\Users\\ \\AppData\\Local\\Discord\\Discord.exe", "vscode": "C:\\Users\\ \\AppData\\Local\\Programs\\Microsoft VS Code\\Code.exe", "figma": "C:\\Users\\ \\AppData\\Local\\Figma\\Figma.exe" } }

Weavetab auto-attaches via CDP to the registered process. No code changes required in the target application.

Zero-API CAPTCHA Solving

browser_captcha solves Cloudflare Turnstile, reCAPTCHA v2/v3, GeeTest, and hCaptcha by orchestrating CDP mouse events that replicate human behavioral signatures — velocity curves, micro-pauses, scroll inertia — with no third-party API, no external service, and no API key required.

Security

Transport: Both CDP WebSocket and MCP WebSocket daemon (--ws) are strictly bound to 127.0.0.1 with 256-bit shared-secret Bearer/handshake authentication and Origin/Host validation. No listener on external interfaces.
Policy Engine: Per-domain allow / read-only / deny / audit rules under the top-level policies array in ~/.weavetab/config.json (blocks *.bank.* and paypal.com out of the box)
RBAC: Five roles — operator (default), viewer (least-privilege read-only), automation, system, admin — enforce tool-level permission gates
Plugin Trust & Manifests: 3-tier verification (@weavetab/* official, verified registry allowlist, and mandatory interactive confirmation + weavetab.json permission manifest inspection for unverified packages)
Blind Injection: Credentials resolved server-side, masked in all outputs and audit logs
Loop Breaker: Strike-based stuck-loop detector halts runaway autonomous sequences
Audit Log: All tool invocations, policy decisions, and errors written to ~/.weavetab-system/logs/mission_ .log

Security vulnerabilities: security@fy2ne.me (do not use public issues).
