Inspector

Inspector is a visual testing tool for MCP (Model Context Protocol) servers that helps developers validate and visualize server behavior and responses.

Overview

Inspector is a visual testing and validation tool for MCP (Model Context Protocol) servers. It provides an interactive UI to display model context responses, request-response flows and behavioral differences, helping developers debug and regression-test MCP services locally or within CI pipelines.

Key Features

  • Visual request/response inspection: structured views that show context contents, response diffs and timelines.
  • CI integration: can be embedded into CI pipelines for automated regression verification.
  • Multiple presentation modes: supports JSON, tabular and plain-text views for easy comparison and analysis.
  • Open-source: MIT licensed for community extension and integration.

Use Cases

  • MCP service development and debugging: inspect request/response behavior locally or remotely.
  • Automated regression testing: run visual checks in CI to quickly surface regressions.
  • Demonstrations and teaching: visualize model-service interactions for team demos or educational material.

Technical Highlights

  • Interactive visualization components built with modern frontend technologies for efficient rendering of large responses.
  • Lightweight integration: APIs and adapters to connect with existing MCP services or testing frameworks.
  • Community-driven development under MIT license for broad ecosystem collaboration.
