flato-design-mcp-guide

flato-design-mcp-guide is a skill for Claude Code, Codex from sologovision/flato-design-mcp. It costs 62 tokens per session (1,317 once invoked), scanned A, original, MIT.

A usage guide for Flato, an editable visual design canvas, through MCP tools that let an agent read project context and make design changes. It explains how to connect to an account and target the correct project.

In plain words
What is it for?
Creating, editing, inspecting, exporting, and troubleshooting Flato designs through its MCP connection.
Why use it?
It gives the agent the required setup and operating rules before it changes a design. This helps avoid editing the wrong project or relying on missing canvas information.

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.

Security

Grade A, and why

flato-design-mcp-guide 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 12d 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.

Flato Design MCP Guide

Use this skill whenever the user wants an AI agent to operate a Flato design through MCP.

Flato is an editable visual design canvas. The MCP server gives agents tools, resources, prompts, project targeting, image capabilities, and feedback. It is not a hidden one-shot design agent. The agent must read current Flato context explicitly and then call concrete MCP tools.

Account And Plan Boundaries

A Flato account is required for OAuth. A paid Flato subscription is not required to install, connect, or start using Flato Design MCP.

Do not tell users they must subscribe before connecting. If an MCP response says a feature is limited by plan, usage, export, workspace, or credits, report that specific limitation and suggest the next available path.

Required Bootstrap

Before any design write:

  1. Read Flato MCP resources when the host exposes resource reading.
  2. Read flato://canvas/fundamentals-v1, or call flato_get_canvas_fundamentals as a fallback.
  3. Call flato_whoami.
  4. Establish a target project:
    • New design: call flato_create_project.
    • Existing editor/project URL: call flato_use_project.
    • Share URL: call flato_use_share_link to create an editable copy.
  5. If the response says the live editor is needed, open editorUrl when the host supports URL opening. Otherwise ask the user to open it.
  6. Poll flato_get_project_status until canWrite=true.
  7. Call flato_get_design_context before each create or edit sequence.

Do not call write tools until canWrite=true.

Targeting Rules

  • Prefer projectId for saved projects.
  • Use clientId only when targeting a specific live editor tab.
  • Use draftId for an unsaved /editor canvas.
  • Never guess pageId or blockId.
  • Use ids returned by a fresh flato_get_design_context or flato_get_state.
  • Selection is only a call-time snapshot. Re-read context before a selection-dependent edit.

Write Rules

  • Create pages with flato_create_pages.
  • Update existing pages or blocks with flato_update_pages.
  • Use updateBlocks[].blockId for existing blocks and createBlocks for new blocks.
  • Change canvas size, grid, padding, page/global background defaults, or scope with flato_update_canvas.
  • Set reusable project CSS with flato_set_global_style. CSS must be scoped under .Canvas.
  • Delete blocks with flato_delete_block.
  • Switch, duplicate, delete, or move pages with flato_page_operation.
  • Use flato_make_backup before risky broad edits.

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.
