About Draw.io MCP Server (community)
This community Draw.io MCP server lets agents build diagrams live in Draw.io, through a built-in editor or a browser extension. It targets specific documents and pages across tabs, serialises operations per document so several agents can work at once, auto-discovers AWS, GCP, Azure and Cisco stencils, and can write its own config for Claude Code, Claude Desktop, Codex, Zed and OpenCode.
Draw.io MCP Server (community) is listed in this index written primarily in TypeScript, with 1.5k stars on GitHub. Its latest recorded repository push was in November 2026; that is not an ASE editorial review date.
Before connecting: access and data
This record's specific permissions have not been reviewed by ASE. Read the publisher's documentation before copying setup or connecting.
- List the accounts, files and services the enabled tools can read, change or execute. Check your actual credentials and discovered tools.
- Use narrowly scoped credentials and read-only mode where supported. Review proposed writes before approving them; a generated configuration does not apply these limits for you.
- Local launch is not local-only data processing. External services receive requests, and your client may pass tool results to its model provider. Check both destinations before sharing private data.
- Keep keys and browser session files out of shared config, repositories and screenshots. Know how to disconnect the server and separately revoke its credentials or account sessions.
