Mockagent — Demo video

MockAgent is a developer-focused testing platform for AI agents that makes it easy to simulate, test, and debug tool interactions without relying on live APIs or external services. It provides configurable mock HTTP endpoints for agent tools, validates incoming arguments against JSON Schemas, returns predictable mock responses, and records every interaction for debugging and analysis. MockAgent helps developers identify incorrect tool calls, test edge cases, reproduce failures, and build reliable AI agent workflows before deploying them to production. It reduces development costs, eliminates dependency on external APIs during testing, and makes AI agent development faster, safer, and more predictable.
