SecureAnnex MCP Server

What is SecureAnnex MCP Server?

SecureAnnex MCP Server is a Model Context Protocol server for analyzing browser extension security. It provides tools for querying, analyzing, and evaluating security aspects of browser extensions—including vulnerability detection, signature checking, code review, and more—via the SecureAnnex API. It is designed for use with Claude Desktop and other MCP-compatible clients.

How to use SecureAnnex MCP Server?

Download or clone the repository and ensure pyproject.toml is present. Configure Claude Desktop by editing claude_desktop_config.json to point uv at the server directory and set the SECUREANNEX_API_KEY environment variable. Once configured, Claude can invoke tools such as search_extensions, get_extension_vulnerabilities, get_extension_signatures, and others directly through natural language.
