Model Context Protocol

VSDX.ai MCP server

Let coding agents generate Visio diagrams and convert draw.io files using your VSDX.ai credits.

Create API key first

Server URL

https://vsdx.ai/api/mcp

ChatGPT and Claude web use OAuth when you add the connector (no API key in the URL). Claude Code, Cursor and Codex use Authorization: Bearer vsdx_… or x-api-key — create keys in Settings → API keys.

Connect your client

  1. In ChatGPT: Settings → Apps & Connectors → Advanced → enable Developer mode.
  2. Add a custom connector and paste the server URL:
    https://vsdx.ai/api/mcp
  3. Save, then choose Sign in when prompted and approve access on VSDX.ai.
  4. Ask ChatGPT to use the VSDX connector to generate or convert diagrams.

Agents can read the full guide at /mcp/install.md
