Draw.io MCP Server connects AI agents to Draw.io, a diagramming application, through the Model Context Protocol. Users can create, edit, manage, import, export, and persist diagrams across documents and pages from supported agent environments. The catalogue entries package the server with commands, instructions, a plugin, and settings for agent-based diagram workflows.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00010 | $0.00289 |
| Opus 5 | $0.00005 | $0.00144 |
| Sonnet 5 | $0.00002 | $0.00058 |
| Haiku 4.5 | $0.00001 | $0.00029 |
Grade A, and why
drawio-status scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
- Bash(curl:*) What it actually says
You are producing a status snapshot of the Draw.io MCP server.
Steps:
- Build the base URL from env vars:
HOST=${DRAWIO_MCP_HOST:-localhost},PORT=${DRAWIO_MCP_HTTP_PORT:-3000},SCHEME=httpsifDRAWIO_MCP_TLS=trueelsehttp.
curl -sf ${SCHEME}://${HOST}:${PORT}/health— if this fails, reportServer: DOWNand stop.- Call
mcp__drawio__list-documents. - Render:
Server: UP (<url>, TLS <on|off>)
Clients: <N> connected
├─ <connection-id-1> (<transport>) doc: <label> <pages> pages
└─ <connection-id-2> (<transport>) doc: <label> <pages> pages
If list-documents returns 0 clients:
Server: UP (<url>, TLS <on|off>)
Clients: 0 connected
And add the hint: "Open Draw.io in your browser, or start the server with --editor."
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

drawio-status is a command published in the GitHub repository lgazo/drawio-mcp-server (1,459 stars, last pushed 7d ago), licensed MIT. It adds 10 tokens to every session and 289 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-02.
