## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-10-04.

- **Endpoint Security**: 80/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 82/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 740 tokens (~185/item across 4 items; 3 tools + 1 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 17/100
  - Stability observed for 5 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).
  - Supports UI / widget rendering.

## Install

### How do I install the GitDiagram MCP server?

GitDiagram is a hosted endpoint at https://gitdiagram.com/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The mcpServers block is a cross-client convention. Remote transports vary, so check your client's docs.

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-10-03 (score 77, +1)

No change was recorded against any check on this day. Stability & Change Management went from 10 to 13. That category is still filling its 30-day observation window: 3 days of observed history at the previous scan, 4 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-10-01 (score 76, +1)

No change was recorded against any check on this day. Stability & Change Management went from 3 to 7. That category is still filling its 30-day observation window: 1 days of observed history at the previous scan, 2 at this one. The score rises as the window fills, whether or not the server changes.

## MCP tools (3)

### `get_repository_diagram` (~252 tokens)

Get a GitHub repository's architecture 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.

Input parameters:

- `repository` (string, required): The GitHub repository as "owner/repo" (e.g. "fastapi/fastapi") or any github.com URL inside it (e.g. "https://github.com/vercel/next.js/tree/canary/packages").

### `find_repository_diagrams` (~170 tokens)

Search GitDiagram's architecture 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.

Input parameters:

- `limit` (integer): How many repositories to return (1–10, default 10).
- `query` (string, required): Part of a repository's "owner/repo" name, e.g. "fastapi", "microsoft/", or "next.js".

### `get_explainer_video` (~185 tokens)

Get a GitHub repository's 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.

Input parameters:

- `repository` (string, required): The GitHub repository as "owner/repo" (e.g. "fastapi/fastapi") or any github.com URL inside it (e.g. "https://github.com/vercel/next.js/tree/canary/packages").

## Common questions

### What is the GitDiagram MCP server?

GitDiagram is an MCP server listed in the public MCP registry as com.gitdiagram/gitdiagram. Architecture diagrams, explanations and Mermaid source for public GitHub repositories. This page covers its hosted endpoint (https://gitdiagram.com/mcp).

### Is the GitDiagram MCP server safe to use?

GitDiagram scores 77 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the GitDiagram MCP server expose?

GitDiagram exposes 3 tools: get_repository_diagram, find_repository_diagrams, get_explainer_video. Their descriptions and schemas cost roughly 607 tokens of context every time the server is loaded.

### Does the GitDiagram MCP server require authentication?

No. We connected to GitDiagram without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the GitDiagram MCP server still maintained?

GitDiagram is still listed as active in the MCP registry. We last reached this channel on 4 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
