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 →
Supply Chain Security98
- No malware found by supply-chain analysis.Pass
- No known CVEs affecting this package version or its production dependencies.Pass

- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability69
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 902 tokens (~180/item across 5 items; 5 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail

- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 92% of tool parameters carry a description.Partial
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 5 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

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 →
compress_image Compress image ~216
Compress a PNG, JPEG, WebP, or AVIF image with Tinify.dev and write the smaller file next to the original (or to output_path). The API never returns more bytes than it received; when it cannot shrink the file the tool says so honestly (optimized: false) instead of pretending.
| Name | Type | Req | Description |
|---|---|---|---|
| output_path | string | – | Absolute path to write the result. Default: <name>.min.<ext> next to the input. The source image is never overwritten unless output_path points at it AND overwrite is true. |
| overwrite | boolean | – | Allow replacing an existing file at the output path. Default false. |
| path | string | yes | Absolute path to the image (png, jpg, jpeg, webp, avif; max 40 MB). |
| quality_mode | string | – | balanced (default), best_quality, or lossless. lossless is rejected for JPEG inputs. |
| target_size_kb | integer | – | Aim for a result at or below this many kilobytes (beta; server rollout). |
| Name | Type | Req | Description |
|---|---|---|---|
| change_percent | number | yes | Byte change in percent; negative means smaller. |
| height | number|null | yes | – |
| optimized | boolean|null | yes | false when the API could not shrink the file and returned the original bytes; null when the concept does not apply (resize/crop). |
| original_bytes | number | yes | Input size in bytes. |
| output_path | string|null | yes | Where the result was written, or null when nothing was written. |
| request_id | string | yes | Quote this when contacting support. |
| result_bytes | number | yes | Result size in bytes. |
| saved_bytes | number | yes | original_bytes - result_bytes. |
| width | number|null | yes | – |
| wrote | boolean | yes | Whether a file was written. |
No examples provided.
convert_image Convert image format ~184
Convert an image to AVIF, WebP, JPEG, or PNG with Tinify.dev (beta endpoint; may not be enabled on every account yet). Writes <name>.min.<new-ext> next to the original unless output_path is given. Converting to the same format is rejected by the API (same_format_conversion).
| Name | Type | Req | Description |
|---|---|---|---|
| format | string | yes | Target format. |
| output_path | string | – | Absolute path to write the result. Default: <name>.min.<ext> next to the input. The source image is never overwritten unless output_path points at it AND overwrite is true. |

crop_image Crop image ~196
Crop a PNG, JPEG, WebP, or AVIF image with Tinify.dev to the given rectangle and write the result next to the original (or to output_path). The source image is never overwritten silently.
