photoshop-mcp: Instructions file for Codex

AGENTS.md

photoshop-mcp AGENTS.md is an instructions file for Codex, OpenCode from alisaitteke/photoshop-mcp. It costs 1,897 tokens per session, scanned A, original, MIT.

Project instructions for using PhotoshopMCP, a tool that lets an AI assistant control Adobe Photoshop through a connection. They describe how to start it, its architecture, and its prerequisites.

In plain words
What is it for?
They help configure PhotoshopMCP for coding editors or a standalone chat interface, check that Photoshop and Node.js are available, and understand how commands reach Photoshop.
Why use it?
They give an agent a clear entry point and workflow for working with Photoshop instead of leaving setup and tool selection unclear.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions .claude-plugin; mentions Claude Code; mentions AGENTS.md.

This is alisaitteke/photoshop-mcp's own configuration. It tells Codex and OpenCode how to work on photoshop-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything photoshop-mcp configures →

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

photoshop-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 29d 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.

Entry strategy

Scenario Path
Cursor Install the photoshop-mcp plugin (Customize → Plugins / Marketplace) so the Photoshop logo appears in the MCP list. Fallback: mcpServers → npx -y @alisaitteke/photoshop-mcp (stdio, generic icon)
Claude Desktop / VS Code Configure mcpServers → npx -y @alisaitteke/photoshop-mcp (stdio)
Claude Code Install this repo as a plugin (skills + MCP). Tools only: claude mcp add photoshop -- npx -y @alisaitteke/photoshop-mcp
Standalone chat UI (no IDE) npx -p @alisaitteke/photoshop-mcp ui
Local development npm install && npm run build && node dist/index.js — see docs/development.md

Prerequisites: Photoshop running on Windows or macOS, Node.js 18+. This is unofficial and not affiliated with Adobe.

Tool surface: 128 MCP tools — 111 atomic photoshop_* + 17 recipe photoshop_recipe_*; 24 MCP prompt templates (ps.*).

Architecture (agent view)

AI host (Cursor / Claude / UI)
  │  MCP stdio
  ▼
PhotoshopMCPServer (Node.js)
  │  ExtendScript via AppleScript (macOS) or COM (Windows)
  ▼
Adobe Photoshop

Optional: UXP bridge plugin (uxp-plugin/) on 127.0.0.1:38452 for Neural Filters only.

Deep dive: docs/architecture.md.

Follow the server instructions advertised on MCP initialize (src/prompts/instructions.ts). Plugin installs also load skills/photoshop-remove-background and skills/photoshop-recipes when the request matches; those hold the phrase-to-tool glossary. The initialize text stays the session contract.

1. DISCOVER: tools/list + prompts/list (or get_capabilities once per session)
2. STATE:    photoshop_get_state before mutating; photoshop_get_preview after major steps
3. ACT:      prefer photoshop_recipe_* for multi-step outcomes (single undo step)
4. RECOVER:  on error, read structured envelope (code, suggested_next_tool) → get_state → retry one step

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.
