Connect to MCP servers and invoke tools, resources, and prompts with custom parameters to validate responses before agents call them in production.

Book Demo Get Started with Insomnia

Call tools, inspect resources, and validate prompts to ensure they work exactly as expected before agentic consumption in production.

Prevent costly agent failures, avoid broken workflows that frustrate end users, and protect your reputation by shipping MCP servers with confidence.

Validate once in Insomnia, deploy with confidence, and ensure your agents deliver reliable results from day 1.

Call any tool with custom parameters to validate response, test edge cases, and catch issues before agents do in production.

MCP Testing for every team

Whether you’re a solo developer or an enterprise team, create MCP clients on all our plans.

Turn APIs into MCP servers in Kong Konnect, or bring your own MCP servers from any source, and validate them in Insomnia by testing tools and verifying responses before agents use them.

Bridge the gap between your existing API infrastructure and the AI-powered future without the risk.

Inspect the complete authentication sequence in the MCP Auth event log to see exactly which calls succeed and where the problem is.
