MCPJam Inspector is a tool for developers building AI applications. It lets you test and debug your AI servers, chat with AI models, and evaluate their performance. You can use it online or install it locally.
MCPJam Inspector is a comprehensive development platform for MCP servers, MCP apps, and ChatGPT apps. It provides a suite of tools for debugging, testing, and evaluating AI integrations. Key features include a chat interface to interact with any LLM, a debugger to inspect every JSON-RPC message and OAuth exchange, an inspector to explore server tools/resources/prompts, an evaluation system to run evals across multiple LLMs and track accuracy over time, a CLI for terminal-based probing and doctor checks, an SDK for programmatic inspections and assertions, and CI/CD integration via GitHub Actions. It supports both hosted web app (no install) and local desktop/terminal versions. MCPJam aims to replace ngrok and paid subscriptions for MCP development.
