For AI Agents
The Diagrams toolset is available via the Graffiticode MCP
server at
https://mcp.graffiticode.org/mcp. No account — and no credential — is
required to try it: call the MCP server with no Authorization header and
your work is scoped to your MCP session (the free plan).
Discovery artifacts
/llms.txt— human-readable summary, endpoint, routing instruction./.well-known/mcp.json— machine-readable config: canonical MCP endpoint, language list, view/console URL templates.
Both files are endpoint-only (no credential) and generated at build time from
scripts/generate-agent-discovery.mjs.
Languages available
- L0169 (Concept Web) — radial concept web diagrams with a central anchor and connected peripheral concepts.
One-call example
create_item({
language: "L0169",
description: "A concept web with 'Photosynthesis' at the center connected to Light Reactions, Calvin Cycle, Chlorophyll, and ATP Production."
})
The MCP server returns an item_id and a view_url. Open the view URL to
see the rendered, interactive diagram. To iterate, call update_item with
the same item_id and a modification description in natural language — do
not attempt to generate Graffiticode domain-language code directly.
Persistence and claiming
Free-plan items are kept for 48 hours. To save them permanently, follow the
claim_url returned in each create_item response, or sign in at the
Graffiticode console.
Email sign-in is available — no Ethereum wallet required.
