Overview

Unlock advanced MCP capabilities in Claude.ai. Features OAuth 2.0, secure storage, and auto-connect.

Unlock the full power of the Model Context Protocol (MCP) directly within Claude.ai. This extension acts as a secure bridge, allowing you to connect Claude to your own local or remote MCP servers with enterprise-grade security. Whether you are a developer testing new tools or a power user integrating custom workflows, Claude MCP Bridge provides a seamless and secure connection layer. 🚀 Key Features: • Advanced Security: Built with a security-first approach featuring SSRF protection, strict URL validation, and XSS prevention. • OAuth 2.0 Support: Full support for PKCE flow authentication, ensuring secure connections to protected servers. • Encrypted Vault: Sensitive credentials and tokens are stored using AES-256-GCM encryption locally on your device. • Modern UI: A beautiful, intuitive interface built with Svelte 5, featuring dark mode support. • Auto-Connect: Smart reconnection logic ensures your tools are always ready when you are. • Keyboard Shortcut: Press Alt+Shift+G to quickly open the Manager. • Manifest V3: Fully compliant with the latest browser extension standards for performance and privacy. 🛡️ Privacy & Security: Your data stays yours. Tokens and configurations are stored locally on your device. We do not track your usage or transmit data to external servers.
