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.
