About MCP Browser Console

MCP Browser Console streams Chrome console, error, fetch, and XMLHttpRequest events to a local MCP server. It helps developers inspect frontend logs and network activity from MCP-compatible clients without switching context. The extension captures console messages, runtime errors, unhandled promise rejections, fetch requests, and XHR requests, then forwards them to a local WebSocket endpoint. Key features: - Capture console.log, warn, error, info, debug, and trace - Capture window errors and unhandled promise rejections - Capture fetch and XMLHttpRequest metadata, status, response body, and duration - Send events only to ws://localhost:3712 - Keep the original page behavior unchanged - Use a local MCP server with an in-memory event buffer MCP Browser Console is designed for local development and debugging workflows. It does not send captured browser data to any remote server.
