RoxyBrowser MCP Server 2.0

English | 中文

RoxyBrowser MCP Server 2.0 is a breaking redesign of the RoxyBrowser OpenAPI MCP package. The 1.x line remains available for compatibility maintenance; 2.0 is built for embedded MCP usage, fixed workspace/project context, instance-based configuration, and unit-tested runtime behavior.

Install

npm install @roxybrowser/openapi@beta

Related MCP server: open_browser_use

CLI Usage

roxybrowser-openapi-mcp --api-key "YOUR_API_KEY"

Options:

• -H, --api-host <url>: RoxyBrowser API base URL. Default: http://127.0.0.1:50000

• -k, --api-key <key>: RoxyBrowser API key.

• -t, --timeout <ms>: request timeout. Default: 30000

Environment variables are also supported: ROXY_API_HOST, ROXY_API_KEY, ROXY_TIMEOUT.

Embedded MCP Usage

import { createRoxyMcpServer } from '@roxybrowser/openapi'
import { InMemoryTransport } from '@modelcontextprotocol/sdk/inMemory.js'

const server = createRoxyMcpServer({
  roxy: {
    apiKey: 'YOUR_API_KEY',
    apiHost: 'http://127.0.0.1:50000',
  },
  context: {
    workspaceId: 123,
  },
})

const [clientTransport, serverTransport] = InMemoryTransport.createLinkedPair()
await server.connect(serverTransport)

When context.workspaceId is provided, workspace-scoped tools no longer expose workspaceId in their public MCP schema. The runtime injects it into tool calls automatically and rejects conflicting caller-provided values.

In fixed workspace mode, roxy_workspace_list is hidden and roxy_project_list is exposed instead. roxy_project_list returns projects under the bound workspace.

SDK Client

import { RoxyClient } from '@roxybrowser/openapi'

const client = new RoxyClient({
  apiKey: 'YOUR_API_KEY',
  apiHost: 'http://127.0.0.1:50000',
})

const health = await client.request('/health')

Tool Names

Public MCP tool names use OpenAI-safe underscores:

• roxy_workspace_list

• roxy_project_list (fixed workspace mode)

• roxy_health_check

• roxy_browser_list

• roxy_browser_create (array input; supports one or many browsers)

• roxy_browser_open

• roxy_browser_close

• roxy_browser_update

• roxy_browser_delete

• roxy_browser_detail

• roxy_browser_connection_info

• roxy_browser_clear_local_cache

• roxy_browser_clear_server_cache

• roxy_browser_list_labels

• roxy_proxy_list

• roxy_proxy_detail

• roxy_proxy_create (array input; supports one or many proxies)

• roxy_proxy_detect

• roxy_proxy_modify

• roxy_proxy_delete

• roxy_account_list

• roxy_account_create (array input; supports one or many accounts)

• roxy_account_modify

• roxy_account_delete

Development

npm install
npm run build
npm test

The test suite uses node:test and includes runtime, client, MCP InMemoryTransport, tool catalog coverage, and real RoxyBrowser API integration coverage.

Real integration tests load .env through dotenv/config and require:

ROXY_API_KEY="YOUR_API_KEY"
ROXY_API_HOST="http://127.0.0.1:50000"
ROXY_TEST_WORKSPACE_ID="123"
