Hosted Playwright API for AI agents. Returns a11y trees instead of screenshots.

This MCP server provides a hosted Playwright API for AI agents. It returns accessibility trees rather than screenshots, which can reduce LLM token usage versus rendering typical pages. The server is described as an MCP for Rove.

🛠️ Key Features

Hosted Playwright API for AI agents
Returns accessibility trees instead of screenshots
README reports ~77% token reduction (26K vs 114K tokens on a typical page)

🚀 Use Cases

AI agents that need structured page understanding via accessibility trees
Agent workflows where screenshot extraction is less efficient than accessibility data

⚡ Developer Benefits

Lower token consumption for page analysis (as stated in the README)
Faster integration path via an npm-installed MCP package

⚠️ Limitations

Provided README excerpt does not cover authentication/limits beyond using an environment variable for ROVE_API_KEY
No additional tool count or capabilities beyond Playwright + accessibility trees are stated

@roveapi/mcp

MCP server for Rove — a hosted Playwright API for AI agents.

Returns accessibility trees instead of screenshots, reducing LLM token consumption by ~77% (26K tokens vs 114K for a typical page).

Quick Start

bash

npx -y @roveapi/mcp

Set your API key via environment variable:

bash

ROVE_API_KEY=rvp_live_... npx -y @roveapi/mcp

Install in Claude Code

bash

claude mcp add --scope user rove -e ROVE_API_KEY=rvp_live_YOUR_KEY -- npx -y @roveapi/mcp

Install in Claude Desktop

Add to claude_desktop_config.json:

json

{
  "mcpServers": {
    "rove": {
      "command": "npx",
      "args": ["-y", "@roveapi/mcp"],
      "env": {
        "ROVE_API_KEY": "rvp_live_YOUR_KEY"
      }
    }
  }
}

Install in Cursor

Add to .cursor/mcp.json:

json

{
  "mcpServers": {
    "rove": {
      "command": "npx",
      "args": ["-y", "@roveapi/mcp"],
      "env": {
        "ROVE_API_KEY": "rvp_live_YOUR_KEY"
      }
    }
  }
}

Tools

Tool	Description
`navigate`	Navigate to a URL. Auto-creates a session. Supports stealth mode and action jitter.
`interact`	Click or fill actions in the active session.
`extract_schema`	Extract structured data from a URL using a JSON schema.
`screenshot`	Take a screenshot (in-session or standalone).
`get_a11y_tree`	Get the accessibility tree snapshot — the core differentiator.
`close_session`	Close a browser session and release resources.

Why Accessibility Trees?

Traditional browser automation returns screenshots that cost ~114K tokens per page. Rove returns structured accessibility trees at ~26K tokens — 77% fewer tokens, faster responses, and better structured data for LLMs to reason over.

Configuration

Environment Variable	Default	Description
`ROVE_API_KEY`	`rvp_live_demo`	Your Rove API key
