undetectable-local-api-mcp-ts

Model Context Protocol server (TypeScript) wrapping the Undetectable Browser Local API https://api-docs.undetectable.io/. Lets Claude / any MCP client drive the antidetect browser: create profiles, manage proxies, import/export cookies, start/stop browsers in parallel, attach via CDP.

Install

As an MCP server (recommended)

No install step needed — npx will fetch and run the package on demand. Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "undetectable-local-api-ts": {
      "command": "npx",
      "args": ["-y", "undetectable-local-api-mcp-ts"],
      "env": {
        "UNDETECTABLE_BASE_URL": "http://127.0.0.1:25325",
        "UNDETECTABLE_TIMEOUT": "60"
      }
    }
  }
}

Env

• UNDETECTABLE_BASE_URL — default http://127.0.0.1:25325
• UNDETECTABLE_TIMEOUT — seconds, default 60

From source (for contributors)

git clone https://github.com/undetectable-io/Undetectable-browser-MCP
cd Undetectable-browser-MCP
npm install
npm run build

Run

# Production (compiled JS)
node dist/server.js

Connect to other AI clients

This server speaks the standard MCP stdio transport, so any MCP-aware client can use it. The package is published on npm, so most clients can launch it directly via npx with no install step.

Claude Code (CLI)

claude mcp add undetectable-ts -s user -- npx -y undetectable-local-api-mcp-ts

Pass -e KEY=VAL flags to override UNDETECTABLE_BASE_URL / UNDETECTABLE_TIMEOUT if needed.

Claude Desktop

Already covered in the Install block above. Config file lives at:

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

Cursor

Edit .cursor/mcp.json (project) or ~/.cursor/mcp.json (global):

{
  "mcpServers": {
    "undetectable-local-api-ts": {
      "command": "npx",
      "args": ["-y", "undetectable-local-api-mcp-ts"]
    }
  }
}

Windsurf (Codeium)

Edit ~/.codeium/windsurf/mcp_config.json with the same JSON shape as Cursor above.

Cline (VS Code extension)

Open the Cline panel → MCP Servers → "Edit MCP Settings" and paste the same mcpServers block.

Continue.dev (VS Code / JetBrains)

Edit ~/.continue/config.json and add the server under experimental.modelContextProtocolServers with command: "npx" and args: ["-y", "undetectable-local-api-mcp-ts"].

Zed

Edit settings.json (cmd/ctrl + ,) and add the server under "context_servers":

"context_servers": {
  "undetectable-local-api-ts": {
    "command": { "path": "npx", "args": ["-y", "undetectable-local-api-mcp-ts"] }
  }
}

Codex CLI (OpenAI)

Edit ~/.codex/config.toml:

[mcp_servers.undetectable-local-api-ts]
command = "npx"
args = ["-y", "undetectable-local-api-mcp-ts"]

Goose (Block)

Edit ~/.config/goose/config.yaml and add:

extensions:
  undetectable-local-api-ts:
    type: stdio
    command: npx
    args: ["-y", "undetectable-local-api-mcp-ts"]

Anything else

Any client that accepts a command + args stdio spawn will work. Use:

command: npx
args:    -y undetectable-local-api-mcp-ts

For self-built binaries, swap to command: node and args: ["<ABS_PATH>/dist/server.js"].

⚠️ Warning — AI gets full API access. Once this MCP server is connected, the AI assistant can call every endpoint listed below, including destructive ones: deleting profiles, wiping cookies and cache, closing the Undetectable program, sending profiles to / from the cloud, and driving the browser (clicks, navigation, JS execution). The server does not ask for per-action confirmation. Treat the AI as a user with full access to your antidetect setup. Review tool calls before approving them in your MCP client, keep backups of important profiles, and avoid connecting the server to environments you cannot afford to lose.

Tools

27 profile/proxy/listing tools + 11 browser-automation tools + 7 batch tools + raw_request.

Profiles / proxies / listings: status, close_software, list_profiles, get_profile_info, start_profile, stop_profile, create_profile, update_profile, delete_profile, check_profile_connection, send_profiles_to_cloud, make_profiles_local, update_browser_version, clear_profile_cache, clear_profile_data, import_profiles, export_profiles, get_profile_cookies, clear_profile_cookies, list_proxies, add_proxy, delete_proxy, update_proxy, list_groups, list_configs, list_folders, list_timezones.

Browser automation (drives the active tab via the Undetectable HTTP API): browser_open_tab, browser_open_url, browser_click, browser_fill, browser_select_option, browser_scroll_to, browser_focus, browser_press_key, browser_evaluate, browser_get_page_html, browser_screenshot.

Batch (Promise.all fan-out): stop_profiles, start_profiles, delete_profiles, clear_profile_cookies_batch, clear_profile_cache_batch, get_profile_info_batch, update_profiles_batch.

Escape hatch: raw_request.
