  • Auth: Authorization: Bearer <FILTRIX_MCP_API_KEY>
  • Primary tools:
    • generate_image_text
    • edit_image_text
    • get_account_credits

Available MCP tools:

  • get_account_credits
  • generate_image_text
  • edit_image_text

Setup

Required:

  • FILTRIX_MCP_API_KEY

Optional:

  • FILTRIX_MCP_URL (default: https://mcp.filtrix.ai/mcp)

Generate

python scripts/generate.py \
  --prompt "..." \
  [--mode gpt-image-1|nano-banana|nano-banana-2] \
  [--size 1024x1024|1536x1024|1024x1536|auto] \
  [--resolution 1K|2K|4K] \
  [--search-mode] \
  [--enhance-mode] \
  [--idempotency-key KEY] \
  [--output PATH]

Edit

Use this when user wants iterative refinement, style transfer, background changes, object replacement, etc.

python scripts/edit.py \
  --prompt "make the sky sunset orange and add volumetric light" \
  (--image-path /path/to/input.png | --image-url https://...) \
  [--mode gpt-image-1|nano-banana|nano-banana-2] \
  [--size 1024x1024|1536x1024|1024x1536|auto] \
  [--resolution 1K|2K|4K] \
  [--search-mode] \
  [--enhance-mode] \
  [--idempotency-key KEY] \
  [--output PATH]

Mode Mapping

  • gpt-image-1: general quality route
  • nano-banana: fast generation route
  • nano-banana-2: advanced generation route

Recommended Workflow

  1. First pass with generate_image_text (scripts/generate.py).
  2. Use edit_image_text (scripts/edit.py) for targeted changes.
  3. Use a new idempotency_key for each new edit intent.

Idempotency

idempotency_key prevents duplicate billing on retries. If omitted, scripts auto-generate one UUID-based key.
