ComfyUI-AnimaTool
ComfyUI-AnimaTool provides tool interfaces (MCP server, ComfyUI-compatible HTTP routes, and an optional FastAPI server/CLI) that let an AI agent generate Anima anime/illustration images via a running ComfyUI instance. It supports structured prompts, aspect ratio presets, history/reroll, and batch generation (repeat and batch_size), and includes optional LoRA injection behavior.

⚙ Agent Friendliness
🔒 Security
TLS is not specified in the README (examples use plain http://127.0.0.1:8188). Authentication/authorization for remote ComfyUI is optional and appears to rely on bearer token/custom headers rather than strong scoped access control. Secrets are referenced as environment variables (ANIMATOOL_BEARER_TOKEN, ANIMATOOL_HEADERS_JSON), which is generally safer than hardcoding, but there is no documented guidance about logging redaction or strict secret handling. The dependency manifest excerpt does not include vulnerability/lockfile information, so dependency hygiene cannot be verified.
⚡ Reliability
Best When
You have a local or reachable ComfyUI with the required Anima model checkpoints installed, and you want an agent-friendly tool interface that can return images directly to chat clients.
Avoid When
You need a formally specified OpenAPI contract or SDKs out of the box, or you require clearly documented rate limits, retry semantics, and idempotency guarantees for safe automated retries.
Use Cases
- • AI agent-driven generation of anime/illustration images using Anima models hosted in ComfyUI
- • Chat-based image tool-use where outputs should render natively in MCP-capable clients (Cursor/Claude, etc.)
- • Programmatic image generation pipelines with HTTP endpoints (health/schema/history/generate/reroll)
- • Iterative generation workflows using reroll based on prior generation history
- • Batch/queue generation for multiple independent outputs and in-task multi-sample latent batches
Not For
- • Production-grade, internet-exposed public APIs without additional security hardening
- • Use cases requiring strict determinism across runs (seed/randomness behavior is implementation-dependent)
- • Environments where you cannot run/host ComfyUI locally or ensure remote ComfyUI access and model files
Interface
Authentication
The README describes optional authorization only for remote ComfyUI via a bearer token or custom headers. No first-class user authentication/authorization model (accounts, scopes, API keys) is documented for the AnimaTool endpoints themselves.
Pricing
Self-hosted tool wrapper; operational costs are primarily compute/GPU time for ComfyUI and model hosting.
Agent Metadata
Known Gotchas
- ⚠ Required parameters must include specific safety tags (safe/sensitive/nsfw/explicit) and artist names must include '@'.
- ⚠ Remote ComfyUI cannot reliably use LoRA sidecar listing that depends on COMFYUI_MODELS_DIR/model filesystem access; list behavior may differ by deployment.
- ⚠ MCP image rendering may require client-side fixes/preview versions (e.g., Cherry Studio preview mentioned).
- ⚠ Resolution (width/height) must align with spatial_patch_size (README shows divisibility requirement).
- ⚠ Batch generation (repeat/batch_size) increases compute and may trigger timeouts if models are cold-starting.
