Albumentations-MCP with Nano Banana (Gemini)

Natural language image augmentation via MCP protocol. Transform images using plain English with this MCP-compliant server built on Albumentations.

Example: "add blur and rotate 15 degrees" → Applies GaussianBlur + Rotate transforms automatically

Available Tools

Core MCP Tools

• `ping` - Lightweight health check that reports status, version, and timestamp.
• `load_image_for_processing` - Stage remote URLs or base64 payloads and return a session_id for follow-up calls.
• `augment_image` - Run Albumentations pipelines from natural language prompts or named presets.
• `validate_prompt` - Parse prompts and surface the structured transforms without processing images.
• `list_available_transforms` - Enumerate supported transforms with parameter metadata.
• `list_available_presets` - List built-in presets (segmentation, portrait, lowlight).
• `get_quick_transform_reference` - Provide a condensed keyword-to-transform reference for prompting.
• `set_default_seed` - Persist a global seed to keep augmentations reproducible.
• `get_pipeline_status` - Report pipeline configuration, enabled features, and output locations.
• `get_getting_started_guide` - Deliver the structured onboarding walkthrough as a tool response.

VLM (Gemini / Nano Banana) Tools

• `check_vlm_config` - Verify VLM readiness without exposing secrets.
• `vlm_test_prompt` - Low-level text-to-image preview helper (no session required).
• `vlm_generate_preview` - Convenience wrapper for quick prompt/style ideation previews.
• `vlm_apply` - Direct VLM apply endpoint for image-to-image edits with fine-grained controls.
• `vlm_edit_image` - Full session edit flow that includes verification steps.
• `vlm_suggest_recipe` - Generate Albumentations + VLM plans and optionally save under outputs/recipes/.

Install (with or without VLM)

• Core only (Alb augmentations): pip install albumentations-mcp
• With VLM (Gemini): pip install 'albumentations-mcp[vlm]'
• Local dev (with VLM): uv pip install -e '.[vlm]'

Claude/uvx note: include the extra in args when you need VLM

• Latest prerelease with VLM: "args": ["--refresh", "--prerelease=allow", "albumentations-mcp[vlm]"]
• Pin stable with VLM: "args": ["--refresh", "albumentations-mcp[vlm]==1.0.2"]

VLM quickstart (env or file):

# Option 1: env
set ENABLE_VLM=true
set VLM_PROVIDER=google
set VLM_MODEL=gemini-2.5-flash-image-preview
set GOOGLE_API_KEY=...  # or GEMINI_API_KEY / VLM_API_KEY

# Option 2: file (auto-discovered)
# Place a non-secret file at config/vlm.json:
{
  "enabled": true,
  "provider": "google",
  "model": "gemini-2.5-flash-image-preview"
  // api_key may be in file or environment
}

Examples:

# Preview (no input image, no session)
vlm_generate_preview(prompt="Neon night street, cinematic moodboard")

# Edit (image + prompt, full session)
vlm_edit_image(
    image_path="examples/basic_images/cat.jpg",
    prompt=(
        "Using the provided photo of a cat, add a small, knitted wizard hat. "
        "Preserve identity, pose, lighting, and composition."
    ),
    edit_type="edit",
)

# Plan and save a hybrid recipe (Alb + VLMEdit)
plan = vlm_suggest_recipe(
    task="domain_shift",
    constraints_json='{"output_count":3,"identity_preserve":true}',
    save=True,
)
print(plan["paths"])  # outputs/recipes/<timestamp>_<task>_<hash>/

session = load_image_for_processing(image_source="https://example.com/image.jpg")
# Use the returned session_id from the previous call
augment_image(session_id="<session_id>", prompt="add blur and rotate 10 degrees")
