hanzo-tools-gimp

Unified GIMP automation tool for Hanzo AI (HIP-0300).

Drives GIMP 3.0 through the Hanzo GIMP bridge — a clean-room GIMP plug-in (see hanzoai/gimp-mcp) that exposes GIMP's Procedural Database (PDB) over a line-oriented JSON TCP socket. This package is the Python client for that bridge.

This is a clean-room implementation with no GPL lineage: both the bridge and this client use GIMP's documented, public PDB / GObject-Introspection API.

Install

pip install hanzo-tools-gimp

Prerequisites

The Hanzo GIMP bridge plug-in must be running inside GIMP. Briefly:

1. Copy hanzo_gimp_bridge.py (from hanzo/gimp-mcp) into your GIMP 3.0 plug-ins directory (one folder per plug-in, script made executable).
2. Start GIMP and run Filters → Hanzo → Start Hanzo Bridge.
3. The bridge listens on 127.0.0.1:9876 by default (override with HANZO_GIMP_PORT / HANZO_GIMP_HOST).

See the gimp-mcp repo's README.md and PROTOCOL.md for full details.

Usage

from hanzo_tools.gimp import GimpTool, register_tools, TOOLS

# Register with a FastMCP server
register_tools(mcp_server)            # optional host=..., port=...

# Or use the tool directly
tool = GimpTool(host="127.0.0.1", port=9876)

The tool exposes the same action surface as the Hanzo MCP TypeScript gimp tool:

Action	Params	Result
version	—	{bridge, gimp, protocol}
open	path	{image_id, width, height}
export	image_id, path	{image_id, path, saved}
pdb_call	procedure, args	the procedure's return value(s)
new_image	width, height	{image_id, width, height}
image_info	image_id	{image_id, width, height, ...}
list_procedures	prefix?	{count, procedures}
flatten	image_id	{image_id, layer_id}

Every action also accepts host / port overrides.

pdb_call is the generic escape hatch — it can invoke any PDB procedure, so anything GIMP can do is reachable.
