Image Generation MCP

Multi-provider image generation MCP server built on FastMCP. Generate images from Claude Desktop, Claude Code, or any MCP client using OpenAI, Google Gemini, Stable Diffusion (SD WebUI), or a zero-cost placeholder provider.

[Documentation](https://pvliesdonk.github.io/image-generation-mcp/) | [Config wizard](https://pvliesdonk.github.io/image-generation-mcp/latest/configuration-generator/) | [PyPI](https://pypi.org/project/image-generation-mcp/) | [Docker](https://github.com/pvliesdonk/image-generation-mcp/pkgs/container/image-generation-mcp)

Features

Multi-provider: OpenAI (gpt-image-2, gpt-image-1.5, dall-e-3), Google Gemini (gemini-3.1-flash-image, gemini-3-pro-image, gemini-3.1-flash-lite-image), SD WebUI (Stable Diffusion / Forge / reForge), and a zero-cost placeholder for testing.
Per-model style metadata: every model carries a style_profile (strengths, prompt grammar, lifecycle); list_providers includes a top-level warnings array for deprecated models. See Model Catalog.
Keyword-based auto-selection: provider="auto" routes by prompt content (text/logo → OpenAI, photoreal/anime → SD WebUI, draft → placeholder).
CDN-style image transforms: image://{id}/view?format=webp&width=512&crop_x=... resizes / re-encodes / crops on demand without re-generating.
Hybrid background tasks: long-running SD generations run with task=True (poll for status); short OpenAI calls stream progress in the foreground.
MCP Apps gallery + viewer: interactive UI surfaces (browse generated images, edit / crop / rotate) for clients that support app: resources.
Production deployment: Docker (multi-arch), .deb/.rpm with hardened systemd, OIDC + bearer auth, persistent EventStore for HTTP session resumability.

What you can do with it

With this server mounted in an MCP client, you can ask:

"Generate a coffee mug product photo on a worn oak table, 16:9, no text." Routes to gpt-image-1.5 for typography-aware photorealism.
"Create three concept-art variations of a cyberpunk alley at dusk." Composes generate_image with provider="sd_webui" and a stylised checkpoint like dreamshaperXL.
"Crop this image to a 1:1 square centred on the subject and resize to 512px." Uses image://{id}/view?width=512&height=512&crop_x=... resource transforms.
"Show me my recent generations." Browses the gallery via the image://list resource and the MCP Apps gallery viewer.
"Save this style as 'cyberpunk-night' so I can apply it to future requests." Uses the style library, whose markdown briefs the LLM interprets per-provider.
"Replace the background of my last photo with a sunset sky." Uses transform_image with the gallery image_id as a reference (image-to-image via Gemini).

Installation

From PyPI

pip install image-generation-mcp

If you add optional extras via the PROJECT-EXTRAS-START / PROJECT-EXTRAS-END sentinels in pyproject.toml, document them below:

Extra	Includes	Use when
`mcp`	`fastmcp[tasks]>=3.0,<4`	Background-task support (`task=True`), required for long SD generations.
`openai`	`openai>=1.0`	Enables the OpenAI provider.
`google-genai`	`google-genai>=1.0`	Enables the Gemini provider.
`all`	`fastmcp[tasks]` + `openai` + `google-genai`	Everything except SD WebUI (which is HTTP-only, no extra needed).

Example: pip install image-generation-mcp[all].

From source

git clone https://github.com/pvliesdonk/image-generation-mcp.git

cd image-generation-mcp uv sync --all-extras --all-groups

Docker

docker pull ghcr.io/pvliesdonk/image-generation-mcp:latest

To run the newest merged code instead of the newest release, use the rolling edge tag. It is rebuilt on every merge to main and carries no version identity. See Image tags for the full tag list.

docker pull ghcr.io/pvliesdonk/image-generation-mcp:edge

A compose.yml ships at the repo root as a starting point. Copy .env.example to .env, edit, and docker compose up -d.

To attach a remote Python debugger (development only; the protocol is unauthenticated), see Remote debugging.

Linux packages (.deb / .rpm)

Download .deb or .rpm packages from the GitHub Releases page. Both install a hardened systemd unit; env configuration is sourced from /etc/image-generation-mcp/env (copy from the shipped /etc/image-generation-mcp/env.example).

Claude Desktop (.mcpb bundle)

Download the .mcpb bundle from the GitHub Releases page and double-click to install, or run:

mcpb install image-generation-mcp-<version>.mcpb

Claude Desktop prompts for required env vars via a GUI wizard, with no manual JSON editing needed.

For manual Claude Desktop configuration and setup options, see Claude Desktop deployment.

Release channels

Artifacts ship on three channels. Each row lists exactly what that channel publishes.

Channel	Version identity	Artifacts
`edge` (rolling)	None; the commit is the identity	Docker image `:edge` rebuilt on every merge to `main`; `.mcpb` bundle as the `mcpb-bundle-edge` workflow artifact; Claude Code plugin `.zip` as the `plugin-zip-edge` artifact; rolling `unstable` docs version. It leaves no git tag, GitHub release, or PyPI entry behind.
Pre-release	`vX.Y.Z-rc.N`, computed and reviewed in its release pull request	PyPI (as the pre-release `X.Y.ZrcN`); GitHub release with wheels, `sdist`, `.deb`/`.rpm` packages, `.mcpb` bundle, plugin `.zip`, and SBOM attached; Docker image under its immutable `vX.Y.Z-rc.N` tag plus the ordering-aware rolling `rc` tag. Skips the plugin marketplace, the MCP registry, and the docs deploy.
Stable	`vX.Y.Z`	Everything: PyPI, Docker (version tag plus ordering-aware `latest` / `vX` / `vX.Y`), `.deb`/`.rpm`, GitHub release assets (wheels, `sdist`, `.mcpb` bundle, plugin `.zip`, SBOM), plugin marketplace and MCP registry entries (when the release is the newest stable), versioned docs with an ordering-aware `latest` alias.

Pre-releases reach PyPI so that a candidate's .mcpb bundle installs: the bundle points at PyPI rather than carrying the code. Ordinary installers never see them, because a PEP 440 resolver skips pre-releases unless the requirement pins one or you pass --pre. Ask for a candidate by name with pip install image-generation-mcp==X.Y.ZrcN. PyPI spells it in the PEP 440 canonical form, while tags use SemVer. Rolling pointers are ordering-aware, so a patch release cut from an old release/X.Y branch never moves latest-style tags back to older content, and a candidate for an already-released version never moves rc. See Release process for the full model.

Quick start

image-generation-mcp serve                                # stdio transport

image-generation-mcp serve --transport http --port 8000 # streamable HTTP

For library usage (embedding the domain logic without the MCP transport), import from the image_generation_mcp package directly. See the project's domain modules under src/image_generation_mcp/ for entry points.

Server info

The server registers a built-in get_server_info tool (via fastmcp_pvl_core.register_server_info_tool) so operators can confirm the deployed version with a single MCP call. The default response carries server_name, server_version, and core_version. Servers that talk to a remote upstream wire upstream version reporting inside the DOMAIN-UPSTREAM-START / DOMAIN-UPSTREAM-END sentinel in src/image_generation_mcp/server.py; see CLAUDE.md for the wiring pattern.

Configuration

Core environment variables shared across all fastmcp-pvl-core-based services:

Variable	Default	Description
`IMAGE_GENERATION_MCP_KV_STORE_URL`	`file:///data/state`	Persistent-state backend URL shared by every pvl-core subsystem that needs state. `memory://` is in-process and lost on restart; `file:///path` persists on one server; `redis://`, `dynamodb://` and `mongodb://` each need their matching extra. When unset, defaults to `file:///data/state` (the volume family Docker images mount), or to `memory://`; with a warning; on a host where that directory is not usable.
`FASTMCP_LOG_LEVEL`	`INFO`	Log level for FastMCP internals and app loggers (DEBUG / INFO / WARNING / ERROR / CRITICAL). The -v CLI flag overrides to DEBUG.
`FASTMCP_ENABLE_RICH_LOGGING`	`true`	Set false for plain or structured JSON log output.

Domain-specific variables go below under Domain configuration.

Authentication

Callers authenticate via a bearer token or OIDC (mutually exclusive). See the Authentication guide for setup, mapped multi-subject tokens, OIDC, and troubleshooting.

Post-scaffold checklist

After copier copy and gh repo create --push:

Fill in the DOMAIN blocks (every section marked with a DOMAIN sentinel comment) in this README and in CLAUDE.md. The GENERATED-ENV-TABLE-* regions are not DOMAIN blocks; the config generator owns them and rewrites them on every run.
Configure GitHub secrets (see below).
Install dev + docs tooling: uv sync --all-extras --all-groups.
Install pre-commit hooks: uv run pre-commit install.
Run the gate locally: uv run pytest -x -q && uv run ruff check --fix . && uv run ruff format . && uv run mypy src/ tests/.
Push the first commit. CI should be green.
