Copy page Copy page ​ 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. ​ Related Groups * 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. ​ Leadership Role Name Organization GitHub Term WG Lead Cliff Hall Futurescale @cliffhall Ongoing WG Lead Ola Hungerford Nordstrom @olaservo Ongoing WG Lead Bob Dickinson TeamSpark.ai @BobDickinson Ongoing ​ Authority & Decision Rights Decision Type Authority Level Meeting logistics & scheduling WG Leads (autonomous) Proposal prioritization within WG WG Leads (autonomous) SEP triage & closure (in scope) WG Leads (autonomous, with documented rationale) Technical design within scope WG consensus Spec changes (additive) WG consensus → Core Maintainer approval Spec changes (breaking/fundamental) WG consensus → Core Maintainer approval + wider review Scope expansion Core Maintainer approval required WG Member approval WG Member sponsors ​ Membership Name Organization GitHub Discord Level Cliff Hall Futurescale @cliffhall seaofarrows Maintainer Ola Hungerford Nordstrom @olaservo olaservo Maintainer Bob Dickinson TeamSpark.ai @BobDickinson rddthree Maintainer Tobin South Anthropic @tobinsouth tobinsouth Member ​ Operations Meeting Frequency Duration Purpose Working Session Weekly, Wednesdays 11:00 America/New_York 60 minutes Technical discussion, proposal review Meetings are held at meet.modelcontextprotocol.io/tag/inspector-v2-wg .
