Extend AI Toolkit

Extend AI Toolkit provides a Python-based implementation for integrating with Extend's payment and spend management APIs across multiple AI frameworks including Anthropic's Model Context Protocol, OpenAI, LangChain, and CrewAI. Developed by Extend Engineering, it offers tools for managing virtual cards, credit cards, transactions, and expense categories through a configurable permission system. The toolkit enables AI agents to perform actions like retrieving card details, updating transaction data, managing expense categories, and handling receipt attachments. Built with async support and comprehensive testing, it's particularly valuable for existing Extend users who want to delegate spend management tasks to AI assistants or integrate with Claude Desktop.
