| Tool | Description | Behaviour |
|---|---|---|
| find_repository_diagrams | Search GitDiagram's library of ready-made architecture diagrams of public GitHub repositories by owner or repository name. Matches any part of "owner/repo" (e.g. "langchain", "vercel/", "react-native") and returns up to 10 repositories, most-starred first, each with its interactive diagram link. Use it to find a project's exact owner/repo from its name, or to list which repositories of an owner or topic already have diagrams. It searches repository names only, not code or file contents. | Read-only |
| get_explainer_video | Get GitDiagram's narrated explainer video of a public GitHub repository, if one has been made: the link to watch and share it, its title and length, and the full narration transcript, a plain-language walkthrough of what the project is for, what people do with it and how its main parts fit together. Use it when the user wants a video about a repository, something to watch or share instead of read, or a short spoken-style summary of a project. Read-only: it never makes a video; when none exists it says so and links the page where one can be made. | Read-only |
| get_repository_diagram | Get the architecture of a public GitHub repository from GitDiagram (gitdiagram.com): a written explanation of how the codebase is organized, its main components with the source paths they live in, how those components connect, and a Mermaid flowchart of the whole system, plus a link to the interactive diagram, where every component opens its code on GitHub. Use it whenever the user wants to understand, visualize, map or explain a GitHub repository's or open-source project's architecture, structure, main modules or data flow, wants an overview before reading unfamiliar code, or asks for an architecture or system diagram of a repo. Read-only and fast: it returns the diagram GitDiagram has already made. If none exists yet, it returns a link that makes one when opened in a browser. Public repositories only. In chat apps that show interactive views, the result also appears as a zoomable diagram whose components open their code on GitHub. | Read-only |
