Kong has introduced a new version of its open-source API development platform, Insomnia 12. This update aims to make building and testing APIs and MCP servers faster and easier, especially with new AI-powered features. The release is now generally available after being announced on November 4.

Insomnia 12 focuses on helping developers work more efficiently by adding tools that simplify testing and debugging tasks. It now includes native MCP clients, AI mock servers, and smart commit suggestions. These features are designed to reduce manual work and speed up the development cycle.

Native MCP Clients and Improved Testing

One of the major updates is the addition of native MCP clients. These let developers test and debug MCP servers using the same familiar workflows they already use for APIs. Developers can connect directly to their servers, manually trigger any tool or resource, and view protocol messages and responses at every step. This makes it easier to validate what’s being built without complicated procedures.

The testing process is now more streamlined. Developers can quickly verify server behavior and troubleshoot issues in real time. This helps catch problems early and ensures that MCP servers are reliable before deployment.

AI-Driven Mock Servers and Commit Suggestions

Another key feature is AI mock generation. Instead of creating mock servers manually, users can describe what they need in simple language—like providing a URL, a JSON sample, or an OpenAPI specification. The system then automatically creates mock servers that match those requirements. This saves time and makes it easier to simulate complex scenarios for testing.

Insomnia 12 also introduces AI-powered commit suggestions. When developers make changes to their code or configuration, the platform analyzes the differences and history to automatically generate clear, descriptive commit messages. It can also organize files logically, helping teams keep their projects tidy and understandable.

An important aspect of the new version is the flexibility around AI models. Teams can choose whether to run large language models in the cloud or locally, depending on their needs for privacy, performance, and data control. This gives organizations more control over their development environment.

Enhanced Collaboration and Security for Teams

Insomnia 12 is designed to support team collaboration better than ever. The platform offers Git Sync, which seamlessly manages version control and allows team members to work on the same projects across different machines. This makes it easier to coordinate work and keep everything synchronized.

For enterprise users, Kong has added advanced security features. They can now test enterprise-grade security measures like SCIM for identity management, Single Sign-On (SSO), and Role-Based Access Control (RBAC). These tools help organizations manage user permissions and secure their API development workflows.

In summary, Insomnia 12 is a big step forward for developers working with APIs and MCP servers. It combines familiar testing workflows with powerful AI tools that reduce manual effort and speed up development. Whether working alone or in a team, users now have more control, better collaboration options, and smarter automation to build better APIs faster.
