Model Context Protocol (MCP) integration for the Inngest dev server introduces AI-assisted workflows, enhancing the testing and debugging of event-driven, asynchronous functions directly within the development environment. This integration allows AI tools such as Claude Code and Cursor to automatically test functions, monitor execution in real-time, and provide detailed error traces, eliminating the need for traditional manual debugging methods. The MCP server offers eight tools for event management, execution monitoring, and documentation access, all embedded within the CLI for offline use. By connecting AI assistants to the local Inngest dev server, developers can streamline their workflow without external dependencies. This shift marks a new era in serverless function development, with future plans for AI-assisted optimization and error diagnosis.
