70 Trust /100
Trust breakdown (7 categories)

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →

  • No known CVEs affecting this package version or its production dependencies.Pass
  • No install/post-install scripts declared.Pass
  • 31 of 95 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency48

  • Actively maintained (last published 4 days ago).Pass
  • Publishes a security disclosure policy (SECURITY.md).Pass
Schema Quality & AI Usability74
  • AI-judged instruction clarity (excellent).Pass
  • Context-footprint check failed: tool/resource definitions use about 894 tokens (~149/item across 6 items; 6 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management0
  • Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified
Tool Coverage100
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 100% of tool parameters carry a description.Pass
Tool Safety100
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • We read all 6 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
  • An AI judge read all 6 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
  • Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

Unverified: 1 category

A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

MCP tools · 6 exposed · ~894 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
fattly_credits ~42

Shows the current credit balance on the FATTLY account. Read-only and free — call it before an expensive generation to make sure the user has enough credits.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

fattly_generate_audio ~143

Generates AI audio: a voiceover (mode=speech) from text, or music (mode=music) from a description. Returns a link to the mp3 file. Spends credits (price in fattly_list_models → audio); refunded automatically if the generation fails.

NameTypeReqDescription
modestringyesspeech = voiceover, music = music.
secondsintegerMusic length: 15, 30 or 60 (music only).
textstringyesText to read (speech) or a music description (music).
voicestringVoiceover voice, e.g. Rachel, Aria, George (speech only).

No output schema declared.

No examples provided.

fattly_generate_image ~282

Generates an AI image from a prompt (or edits uploaded images). Returns links to the finished images. Spends credits: model price × numImages (see fattly_list_models); fails with an error if the balance is too low, and credits are refunded automatically when a generation fails. Prompts must be safe-for-work.

NameTypeReqDescription
aspectRatiostringAspect ratio, e.g. 1:1, 16:9, 9:16 (default 1:1).
inputImageUrlstringOptional single input image for editing / face-swap models — must be a fal URL. Get one by uploading a local photo with fattly_upload_image.
inputImageUrlsarrayOptional MULTIPLE input images (fal URLs) for multi-image edit models like nano-banana-2-edit / nano-banana-pro-edit. Typical swap use: image #1 = the scene/frame to keep (background, framing, lighti…
modelstringModel id (default nano-banana-2). List: fattly_list_models.
numImagesintegerNumber of images 1–4 (default 1).
promptstringyesDescription of the image to generate.

No output schema declared.

No examples provided.

fattly_generate_video ~251

Generates an AI video from a prompt (or from a start image). Takes a few minutes — the tool waits (up to 10 min) and returns a link to the mp4 file. Video is the most expensive operation: it spends the model's credit price (see fattly_list_models), so confirm the model and cost with the user first. Credits are refunded automatically if the generation fails.

NameTypeReqDescription
aspectRatiostringAspect ratio, e.g. 16:9, 9:16, 1:1 (default 16:9).
durationintegerClip length in seconds (model dependent).
inputImageUrlstringOptional start image for image-to-video — must be a fal URL. Get one by uploading a local photo with fattly_upload_image.
modelstringVideo model id (default kling-3-standard), e.g. kling-3-pro, veo-3-1, veo-3-1-fast, seedance-2-5, hailuo-3, ltx-2-5. Full list with prices: fattly_list_models.
promptstringyesDescription of the video scene.

No output schema declared.

No examples provided.

fattly_list_models ~60

Returns available models and their cost in credits (images, video, audio). Read-only and free. Use before generating to pick the right model id and to tell the user what a generation will cost.

NameTypeReqDescription
categorystringOptional category filter.

No output schema declared.

No examples provided.

fattly_upload_image ~116

Uploads a local image file (JPG, PNG or WEBP) to FATTLY and returns a public fal URL. Use this to turn a photo on disk into an inputImageUrl for editing / face-swap / image-to-video models: pass the returned URL as inputImageUrl to fattly_generate_image or fattly_generate_video. No credits are charged for the upload.

NameTypeReqDescription
filePathstringyesAbsolute path to a local image file (JPG, PNG or WEBP), max 10 MB.

No output schema declared.

No examples provided.
