What is drawio-mcp CLAUDE.md?

Project instructions for the draw.io MCP server, a tool that lets an AI open and create diagrams in the draw.io editor. They describe the repository layout, plugin manifests, and diagram-related tools.

Use them when changing the draw.io server, its plugin marketplace entries, or features for creating and searching diagram shapes.

They help an agent find the right plugin files and use the diagram server consistently across supported coding assistants.

Token cost

What it costs to keep this loaded

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	$0.00005	$0.00005
Opus 5.5	$0.00002	$0.00002
Sonnet 5.5	$0.00001	$0.00001
Haiku 4.5	$0.00001	$0.00001

Security

Grade A, and why

drawio-mcp CLAUDE.md scanned grade A with 0 findings 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 1mo 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Changes

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.
