Group Type
Working Group
Mission Statement
The Inspector V2 Working Group is building Inspector V2, a new web-based MCP inspector redesigned from the ground up for maintainability and reliability. The group delivers a shared Inspector Core architecture that maximizes code reuse across Web, CLI, and TUI implementations, together with a comprehensive testing apparatus. This effort requires cross-maintainer collaboration because it spans UI, protocol tooling, and test infrastructure that no single maintainer owns today.
Scope
In Scope
- The
modelcontextprotocol/inspector repository, including:
- Inspector Core — a new shared-code architecture that provides common MCP and protocol interfaces for all Inspector front-ends.
- Web Inspector UI — browser-based inspector built on Mantine and TypeScript.
- CLI Inspector — command-line interface sharing Inspector Core.
- TUI Inspector — terminal UI sharing Inspector Core.
- Testing apparatus — shared test harnesses, fixtures, and integration tests across all Inspector surfaces.
- Deprecation and migration of the existing Inspector on
main to a v1.x maintenance branch.
- Adoption of MCP TypeScript SDK V2 inside Inspector Core once available.
Out of Scope
- The core MCP specification.
- MCP SDK maintenance (TypeScript, Python, or any other language SDK).
- MCP server implementations.
- SDK WG — Inspector Core consumes the TypeScript SDK; coordination required for SDK V2 adoption.
- MCP Apps WG — shared surface area around client/app ergonomics and inspection workflows.
- Auth WG — authentication flows exercised by Inspector when connecting to protected servers.
- Registry WG — discovery and metadata surfaces that Inspector presents to users.
