Secure MCP Framework by Arcade.dev

Secure MCP Framework by Arcade.dev is a Python-based development framework for building Model Context Protocol servers. It enables developers to create custom tools that AI agents can use, complete with OAuth authentication and secure production deployment capabilities. The framework lets you build tools that connect to various services and APIs, which AI assistants like Claude or Cursor can then access and utilize.

The framework stands out by handling the complex parts of MCP server development automatically. It manages OAuth flows, secret storage, and deployment configuration so developers can focus on writing the actual tool logic. You create tools using simple Python decorators and type annotations, and the framework handles the rest. It works with popular AI clients and development environments without additional configuration.

This framework benefits developers building AI agent systems that need to interact with external services securely. Teams use it to create custom tools for sales agents that access CRM data, educational assistants that integrate with learning platforms, or coding assistants that connect to development tools. The open-source MIT license means companies can use it without vendor lock-in concerns.
