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 | $0.00024 | $0.00324 |
| Opus 5 | $0.00012 | $0.00162 |
| Sonnet 5 | $0.00005 | $0.00065 |
| Haiku 4.5 | $0.00002 | $0.00032 |
Grade A, and why
excalidraw-export 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 9d 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.
What it actually says
/excalidraw-export
Retrieve a live snapshot of the Excalidraw canvas as a resource that can be exported downstream (to SVG, PNG, JSON, or copied into another tool).
Usage
/excalidraw-export <scene|library|theme|elements>
Arguments:
<scene>: full canvas scene JSON (elements, app state, files). This is the canonical export payload.<library>: shared Excalidraw library (reusable elements across scenes).<theme>: active theme (light/dark + custom palette).<elements>: just the elements array, without app state.
The MCP server returns the raw resource; downstream SVG/PNG rendering is the responsibility of the calling tool (e.g. browser-side Excalidraw or a local renderer).
Workflow
- Call
mcp__excalidraw__health_checkto confirm the canvas subprocess is running. - Call
mcp__excalidraw__get_resourcewith the supplied<resource-type>. - Echo the resource payload back to the caller, noting the element count or scene size so downstream tools can decide how to render it.
Example
/excalidraw-export scene
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.
