About The Product

MCPJam Inspector is a local testing tool designed for developing and testing ChatGPT apps and MCP servers. It enables building apps locally with a widget emulator and testing against any LLM in its playground. The tool allows users to inspect MCP server tools, resources, prompts, and OAuth flows.
