Kong Inc. has announced the availability of Insomnia 12, its open-source API development platform designed to streamline the design, mocking, debugging, and testing of APIs.
This new release prominently enhances capabilities for developers working on both APIs and Model Context Protocol (MCP) servers with a range of features that support native MCP clients, AI mock servers, and AI-powered commit suggestions.
Enhancements in Insomnia 12
With the rising adoption of agentic AI, developers tasked with building MCP servers encounter challenges similar to those faced by API developers in the past.
The latest iteration of Insomnia aims to simplify these tasks by extending its user-friendly test-iterate-debug approach to AI-native development. It introduces AI-driven functionalities that minimize manual work and expedite the development process.
Agentic AI Infrastructure
Developers tasked with building MCP servers face challenges similar to those faced by API developers
According to Marco Palladino, CTO and Co-Founder of Kong Inc., "With MCP emerging as the new standard for how AI agents communicate, developers need a reliable way to test, debug, and govern this new protocol. Insomnia 12 addresses this need by extending the same developer-friendly workflows we've built for APIs to the AI-native world."
He added, "We’re empowering organizations to accelerate agentic AI infrastructure development with built-in confidence, collaboration, and scalability."
Notable Features of Insomnia 12
The new version includes several key features aimed at simplifying MCP development:
Native MCP Clients
Developers can now test and debug MCP servers using a familiar workflow, allowing them to connect directly to servers and interact with various tools, prompts, or resources using custom parameters. This integration fosters collaboration and enhances confidence in AI-native development.
AI Mock Generation
Insomnia 12 enables the creation of functional mock servers in seconds by specifying requirements in natural language or through an OpenAPI spec, URL, or JSON sample. This feature turns labor-intensive tasks into quick setups, fostering more efficient testing for both APIs and MCP servers.
AI-Powered Commits
The platform automatically generates informative commit messages by analyzing code differences and history, helping teams maintain organized Git histories, streamline collaboration, and focus on development.
Enhanced AI Compliance
Teams can choose between using cloud-based solutions or a local large language model (LLM), offering control over data and code residency while balancing privacy and performance requirements.
Improved Team Collaboration
Kong Inc. has enhanced collaborative features for API and MCP development in Insomnia 12. Git Sync supports version control and collaboration across devices, while enterprise users can trial advanced security, governance, and compliance features, including SCIM, SSO, and RBAC.
