Editmamei

Editmamei is a pure MCPstdioserver written in Node. Your AI client launches it as a subprocess and calls its tools over stdio. Each tool builds a small Photoshop script and runs it in your local Photoshop over the platform's native automation channel:

AI client ──stdio──▶ Editmamei (Node MCP server) │ builds a Photoshop script per tool call ▼ COM (Windows) / AppleScript (macOS) │ ▼ Your local Adobe Photoshop

- Windowsdrives Photoshop through COM (thePhotoshop.Applicationobject).
- macOSdrives it through AppleScript / OSA.
- Perception (face, object, and scene detection) runson-devicewith local ONNX computer vision, so the model gets real document coordinates without your image leaving the machine.

Photoshop does the pixel work with its own engine. Editmamei is the conductor, not a renderer.

npm install -g editmamei editmamei install # registers with Claude Desktop, Cursor, Claude Code editmamei status # confirms install state + Photoshop detection

Then restart your AI client and ask it:"Is Photoshop connected?"

Requirements:Adobe Photoshop 2026 (v27.x), Windows 10/11 or macOS 12+, Node.js 22+ (for the npm path), and an MCP-compatible AI client (Claude Desktop, Cursor, Claude Code).

The discovery chain isps_ping(liveness), thenps_overview(the working method and capability map), thentools/list(the full schema-typed inventory). After that you just talk to your assistant:

"Open my vacation photo.""Make the sky more dramatic but keep the foreground natural.""Sharpen the eyes, soften the skin, leave everything else alone.""Isolate the subject onto its own layer with a clean mask.""Export a 2048px web JPEG."

Your assistant composes those into tool calls, checks the result with previews and measurements, and iterates.

These are the choices that shape the surface, and the reason an AI assistant can drive it reliably rather than hopefully.

- Structured results, not prose.Every tool declares anoutputSchemaand returns a typed JSON payload. Any tool that changes what is active reports the current document and layer back, so the model keeps an accurate picture of Photoshop's state between calls instead of re-deriving it.
- Guidance lives in the surface.ps_overviewreturns the working method (assess, plan, enact, check, iterate) andps_list_capabilitiesreturns a live map of what exists. The model orients itself from the server rather than from guesswork or a stale prompt.
- Measure, don't eyeball.A dedicated set of verification tools (histogram, region compare, layer-bounds diff, selection preview) lets the model check its own work numerically instead of trusting a thumbnail.
- On-device perception.Local computer vision (ONNX) detects faces, objects, and scene regions and returns real document coordinates. The image stays on your machine for this step and is never sent to a cloud vision model.
- Non-destructive by default.Adjustments are adjustment layers, and destructive pixel operations run on an auto-created duplicate. An edit is reversible by construction.
- Verified against real Photoshop.Every tool is built on Photoshop's own native scripting functions and verified in live Photoshop sessions before it ships. A new tool stays disabled until it has passed live verification, so the shipped surface is the verified surface.
- Built for modern Photoshop.Editmamei targets Photoshop 2026 (v27.x) so it can rely on current, stable scripting descriptors rather than carrying a decade of drifted behavior.

82 tools across 16 capability groups(59 Community, 23 Pro). Every tool is namespacedps_*and discoverable at runtime viatools/list. Community tools ship in both editions; Pro tools unlock with a license.tools/listreports eight more than the table below: the names superseded byfilter,group, andtext(apply_filter,create_group,move_layer_to_group,set_group_blend_mode,ungroup,delete_group,create_text_layer,set_text) stay registered as deprecated aliases for one release, so existing calls keep working.

- Communityis free and covers the everyday editing surface: documents, layers, selections (including AI Select Subject and Select Sky), non-destructive adjustments, filters, masks, type, retouching, on-device perception, and the inspect/verify primitives.
- Proadds Camera Raw develop, the grounded precision tools (warp, named-object masks, precision placement), subject-instance targeting, face-mesh perception, the reproducible-template system, and Photoshop Actions plus the scripting escape hatch.

This repository holds the Community source. Pro is a separately licensed module and its source is not published here; Community never imports it, so this tree builds and runs on its own.

git clone https://github.com/editmamei/editmamei.git cd editmamei npm install npm run build npm test

You need Node.js 22+ and a Go toolchain (the build compiles theeditmamei-corebinary that generates Photoshop scripts). The build warns instead of failing when Go is missing, so you can still run the test suite; setEDITMAMEI_CORE_BINto a prebuilt binary if you would rather not install Go.

The test suite runs without Photoshop. It verifies the ExtendScript Editmamei generates, never that Photoshop accepted it, so live verification against a real Photoshop is a separate step.

Settings live in~/.editmamei/settings.json, managed by theeditmamei configCLI:

editmamei config list editmamei config set telemetry.usage false # turn off anonymous usage telemetry editmamei config set ps_path "/path/to/Photoshop"

PHOTOSHOP_PATH(env var) overrides Photoshop auto-detection for a single run.

The source in this repository is the same code published to npm, so none of the above has to be taken on trust.

Editmamei is not open source under the OSI definition, and we don't call it that. It is source-available, with the full CE stack developed in the open.

Editmamei Pro is a separate, commercially licensed module; its source is not published.
