figma-edit-mcp: Instructions file for Codex

AGENTS.md

figma-edit-mcp AGENTS.md is an instructions file for Codex, OpenCode from neozhehan/figma-edit-mcp. It costs 386 tokens per session, scanned A, original, MIT.

Repository instructions for an MCP server that reads, creates, and changes Figma designs through code. Figma is a collaborative design application for interfaces and visual layouts; MCP is a way for an agent to use connected tools.

In plain words
What is it for?
Guiding automated Figma edits, handling structured tool errors, and applying the server's required safety workflow.
Why use it?
They require the agent to discover the design before editing it and to respect safety checks for scope, names, and batches.

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

figma-edit-mcp AGENTS.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.

What it actually says

AGENTS.md — Using figma-edit-mcp from an AI agent

This server enforces hard safety constraints (scope locking, name verification, batch validation) that you cannot bypass, and it returns structured error codes you need to recover from. Do not operate blind — load the guidance before writing.

The full operational guide lives in one place and is delivered three ways; use whichever your host supports:

  • MCP resources (any client, zero setup): read figma-edit://guide/constraints, figma-edit://guide/error-playbook, figma-edit://guide/workflows, figma-edit://guide/tool-selection.
  • The figma-edit skill (Claude Code, Copilot, Codex, Cursor, Gemini, Antigravity, …): skills/figma-edit/SKILL.md and its references/.
  • In this repo: skills/figma-edit/references/ — constraints.md, error-playbook.md, workflows.md, tool-selection.md.

For the precise enforcement contract behind these constraints — the safety guarantees, the conditions they hold under, the residual risks, and the per-tool gate matrix — see SAFETY.md at the repo root.

Two rules to internalize before anything else:

  1. Discover before acting. Start every node workflow with a read (page_info → node_info); pass names back verbatim.
  2. The plugin can refuse you. Constraints are checked at execution time and return structured errors — plan calls to comply rather than retrying.

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.
