At a glance: 50+ MCP servers across 12 subcategories covering every major generation platform except Adobe Firefly. ComfyUI leads with workflow-based generation (224 stars, 18+ tools). Stability AI has the most polished API wrapper (81 stars, 11 chainable tools). fal.ai provides the broadest model access (600+ models). Midjourney works through unofficial API proxies. Rating: 4.0/5.
ComfyUI — Richest Integration
joenorton/comfyui-mcp-server (224 stars, Python, Apache 2.0, 18+ tools). Auto-discovers ComfyUI workflows and exposes them as MCP tools. Iterative refinement lets agents generate, evaluate, and regenerate with adjusted parameters. Streamable HTTP transport.
Also: shawnrushefsky/comfyui-mcp (40+ tools, 70+ workflows, images/video/audio/3D), artokun/comfyui-mcp (31 tools, 3 autonomous agents, SQLite tracking).
Stability AI — Most Polished API Wrapper
tadasant/mcp-server-stability-ai (81 stars, TypeScript, MIT, 11 tools). Generate, edit, upscale, remove background, outpaint, search-and-replace, control (sketch/style/structure), relighting. All tools chainable in a single conversation. Cloud API — no local GPU needed.
DALL-E / OpenAI
spartanz51/imagegen-mcp (33 stars) — DALL-E 2, DALL-E 3, and gpt-image-1 with txt2img and img2img. jacwu bridges Azure OpenAI for enterprise compliance. 6 servers total in the subcategory.
Flux
jmanhype/mcp-flux-studio (24 stars, 4 tools) — Flux 1.1 Pro/Ultra/Dev, txt2img, img2img, inpaint, structural controls (canny/depth/pose). tehw0lf/flux-mcp runs locally on 12GB+ GPUs with smart VRAM management — zero API costs.
Google Gemini / Imagen
shinpr/mcp-image (82 stars) — auto prompt optimization, 3 quality tiers, up to 4K, character consistency. lansespirit/image-gen-mcp (51 stars) — multi-provider with gpt-image-1 + Imagen-4/3, 10+ prompt templates, STDIO/HTTP/SSE.
fal.ai — Broadest Model Access
raveenb/fal-mcp-server (38 stars, 18 tools) — 600+ models spanning images, video, and audio. Dynamic model discovery, cost tracking. am0y/mcp-fal (76 stars) — model search/discovery, async execution, queue management.
Midjourney — Fragile Proxies
No official API. All 3 servers use unofficial API proxies (GPTNB, AceDataCloud). z23cc/midjourney-mcp (9 stars, 7 tools) — generation, upscale, variations, zoom, pan, inpainting, face-swap. Can break if Midjourney changes their Discord infrastructure.
Replicate & Multi-Provider
- deepfates/mcp-replicate (93 stars) — no longer maintained; Replicate now offers official MCP
- apinetwork/piapi-mcp-server (68 stars) — Midjourney, Flux, Kling, Luma, Suno, Trellis (3D) in one server
- writingmate/imagegen-mcp — 6 model families (OpenAI, Gemini, Flux, Qwen, SeedDream-4) in one server
What's Missing
- Adobe Firefly — no MCP server exists
- Canva AI — no image generation MCP integration
- Dedicated inpainting/outpainting — limited outside ComfyUI
- Image-to-3D pipelines — PiAPI's Trellis is the only option
- Cost comparison tools — no cross-provider pricing optimization
The Bottom Line
Surprisingly mature ecosystem. Local generation: ComfyUI dominates. API-based: Stability AI is most polished; fal.ai has broadest catalog. Cost-conscious: Together AI or local Flux. Quality-first: Midjourney works but is fragile; Ideogram excels at text rendering.
