    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 1089 ms over 2 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 1196 ms over 2 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    2 of 2 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Pass
    Stable tool list

    No tool was removed and no required parameter was added in the last 30 days.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

  • Not measured
    Free tier cited

    No publisher quote has been checked.

  • Pass
    Tools described

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

  • Pass
    Parameters documented

    4 of 4 parameters have a description (100%). The bar is 80%.

  • Pass
    Safety hints

    Every tool sets readOnlyHint or destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Pass
    Website matches publisher

    The website host matches the reverse-domain namespace.

  • Pass
    Source repo linked

    A repository URL is on file.

  • Not measured
    Repo owner matches

    This namespace is not an io.github login, so the owner comparison does not apply.

  • Pass
    Recently updated

    Updated 2026-09-29T20:33:04.730853Z, within 180 days.

Capabilities

Tools 3

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.

Discovered
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.

Discovered
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.
