Holarch

ClaudeCommunityby Angry Pixie Electronics LLC, d/b/a Holarch

Holarch is a model-based systems engineering (MBSE) workbench for SysML v2 and the Lifecycle Modeling Language (LML). This connector lets Claude work with your Holarch projects: requirements, functions, architecture, interfaces, verification, risks and decisions in one connected model. What Claude can do: - Read your projects: search items, open an item with its attributes and relationships, read documents, diagrams and the project schema. - Analyze: run Holarch's Model Checks (missing traces, orphans, interface gaps), score requirement quality, build traceability and verification matrices (RVTM), and read the SysML v2 text of a model. - Trace across a program: follow links between items in different projects (Team plan). - Propose changes: create, update, relate or delete items. Changes are never applied directly; they arrive in Holarch as a proposal that you review, accept or reject, and an accepted proposal is one undoable step. - Answer how-to questions from the published Holarch Docs and Help. Typical uses: review a requirement set for quality and missing verification, draft functions or test cases from requirements and send them for review, find gaps before a design review, or summarize what changed in a project. Requirements: a Holarch account (https://app.holarch.app) on a plan that includes the API and MCP (Individual or Team, including the free 30-day Individual trial). Claude sees only the projects your account can open, with your role in each; sign-in uses OAuth and can be revoked any time in Holarch under Account Settings → API tokens.
