よくある質問

1

What runtimes or dependencies does Blueprint MCP for Chrome require?

It requires Node.js to run the MCP server and a real Chrome browser with the Blueprint extension installed.

2

How does Blueprint MCP for Chrome handle data privacy?

In free local mode, all communication stays on your machine via a localhost WebSocket. There is zero telemetry, tracking, or analytics, and the server works completely offline.

3

What transport protocols are supported?

Free tier uses a local WebSocket on port 5555. Pro tier offers a Cloud Relay for controlling the browser from anywhere and supporting multiple AI clients.

4

Do I need any authentication to use Blueprint MCP for Chrome?

No account is needed for the free local tier. The Pro tier requires a subscription for Cloud Relay but no additional authentication for local use.

5

What are the limitations of Blueprint MCP for Chrome compared to snapshot-based tools?

It does not automatically send page snapshots with every action, which saves context tokens. Content is only fetched when explicitly requested, enabling longer, more efficient workflows without hitting response size limits.
