Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified the GitHub account SaharshPamecha for this listing. That does not show the account is the product's maker.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

A local MCP server that lets an assistant generate draw.io diagrams and architecture designs from natural-language prompts through the DrawX API.

What you can do: Generate draw.io XML from a natural-language prompt, optionally modifying existing diagram XML and choosing a speed/quality mode (flash, pro, ultra). Produce architecture designs from a brief, with high-level design, optional low-level design and design document, and a cloud style such as cloud-agnostic, AWS, Azure or GCP. Check the API key's account, plan, API tier and remaining monthly quota.
When to use it: Useful when you want an assistant to draft draw.io diagrams or architecture design documents inside Claude Desktop, Cursor or VS Code without drawing them by hand. Best suited to users with a paid DrawX plan who already work with diagrams.net or .drawio files.
Requirements: Runs locally over stdio via the npm package @drawx/mcp-server (Node.js 18+), or through npx without installing. Requires a DrawX API key in the DRAWX_API_KEY environment variable; the optional DRAWX_API_BASE variable overrides the API base URL. Network access to the DrawX API is needed.

Before you install

The DrawX API key (DRAWX_API_KEY) is a paid credential stored in the MCP client configuration. API access is a paid feature on a separate metered tier with a monthly call quota and a per-minute rate limit, so usage consumes quota. Prompts and diagram briefs are sent to the DrawX API.

Installation

In SourceWeft

Open Drawx Mcp Server in the dashboard and add it to a workspace.
Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

README

@drawx/mcp-server

[npm version] [CI] [license: MIT]

Generate draw.io diagrams and architecture designs from inside Claude, Cursor, or VS Code.

DrawX MCP is a Model Context Protocol server that gives your AI assistant three tools:

generate_diagram — one-shot: natural-language prompt → complete draw.io XML.
architect_design — from a brief, produce a High-Level Design diagram (optionally an LLD + design doc).
whoami — verify your API key + see remaining quota.

Behind the scenes it calls the DrawX public API, so output matches the DrawX web app exactly.

Requirements

Node.js 18+
A DrawX API key — create one in DrawX → Settings → API keys. Keys start with drawx_live_. API access is a paid feature (bundled with the DrawX Pro plan).

Install

Or, if your MCP client supports npx, no install is needed — reference npx @drawx/mcp-server directly.

Configure your MCP client

Claude Desktop

Edit ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

json

{  "mcpServers": {    "drawx": {      "command": "npx",      "args": ["-y", "@drawx/mcp-server"],      "env": {        "DRAWX_API_KEY": "drawx_live_..."      }    }  }}

{  "mcpServers": {    "drawx": {      "command": "npx",      "args": ["-y", "@drawx/mcp-server"],      "env": {        "DRAWX_API_KEY": "drawx_live_..."      }    }  }}

Restart Claude Desktop. In a new chat, ask "Draw me a microservices checkout flow" — Claude will call generate_diagram and show the resulting XML.

Cursor

Edit ~/.cursor/mcp.json:

json

{  "mcpServers": {    "drawx": {      "command": "npx",      "args": ["-y", "@drawx/mcp-server"],      "env": { "DRAWX_API_KEY": "drawx_live_..." }    }  }}

{  "mcpServers": {    "drawx": {      "command": "npx",      "args": ["-y", "@drawx/mcp-server"],      "env": { "DRAWX_API_KEY": "drawx_live_..." }    }  }}

VS Code (Copilot MCP)

Add to your workspace or user settings.json:

json

{  "mcp": {    "servers": {      "drawx": {        "command": "npx",        "args": ["-y", "@drawx/mcp-server"],        "env": { "DRAWX_API_KEY": "drawx_live_..." }      }    }  }}

{  "mcp": {    "servers": {      "drawx": {        "command": "npx",        "args": ["-y", "@drawx/mcp-server"],        "env": { "DRAWX_API_KEY": "drawx_live_..." }      }    }  }}

Environment variables

Tools reference

`generate_diagram`

Turn a description into draw.io XML.

Inputs

prompt (string, required) — what to draw.
mode — "flash" (default), "pro", or "ultra". Trades speed for quality.
previousXml — an existing mxfile to modify.

Output — assistant text: a summary line (model, tokens, cost) followed by the full <mxfile>...</mxfile> XML in a fenced code block. Paste the XML into diagrams.net or save as .drawio.

`architect_design`

Run the DrawX Architect Co-Pilot on a brief. Streams intermediate progress; returns a JSON payload with hld (and optional lld, doc).

Inputs

brief (string, required, ≥ 20 chars) — what to design.
depth — "hld", "hld_lld" (default), or "hld_lld_doc".
style — "cloud_agnostic" (default), "aws", "azure", or "gcp".
mode — "flash" (default), "pro", or "ultra".

`whoami`

No inputs. Returns your email, plan, API tier, and remaining monthly API quota.

Quota + rate limits

API usage is metered on a separate tier from your in-app usage. Pro subscribers get 200 API calls / month. The rate limit is 60 requests / minute. On the free plan, API access is not enabled — upgrade at getdrawx.com.
