Available components
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 →

- No malware found by supply-chain analysis.Pass
- No known CVEs affecting this package version or its production dependencies.Pass
- No install/post-install scripts declared.Pass
- 47 of 136 dependencies flagged as unhealthy (1 deprecated). View diagnostics → Partial
Provenance & Transparency100
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Cryptographically verified build provenance (signed, bound to nuver-labs/image-gen-mcp). View diagnostics → Pass
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 0 days ago).Pass
- Publishes a security disclosure policy (SECURITY.md).Pass
Schema Quality & AI Usability63
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 1376 tokens (~458/item across 3 items; 3 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
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.

edit_image Edit image ~704
Edit or combine existing image file(s) using a text instruction: modify elements, restyle, add or remove content, or merge references. Reads the source image(s) from disk, saves the result as a NEW file (never overwrites sources), and returns the absolute saved path(s).
| Name | Type | Req | Description |
|---|---|---|---|
| aspect_ratio | string | – | Gemini and OpenAI gpt-image-2 honor the ratio exactly. Older OpenAI models approximate: landscape -> 1536x1024, portrait -> 1024x1536, 1:1 -> 1024x1024. |
| background | string | – | OpenAI only, ignored by Gemini. transparent yields alpha PNG/WebP, ideal for logos and icons. Requires gpt-image-1.5 or older: gpt-image-2 does not support it, so transparent calls on gpt-image-2 aut… |
| image_size | string | – | Gemini 3.x models only (ignored by OpenAI; gemini-2.5-flash-image is fixed at 1024px). Default 1K. |
| input_fidelity | string | – | OpenAI only. high preserves faces, logos, and fine details from the input more faithfully. Ignored on gpt-image-2, which always processes inputs at high fidelity. |
| model | string | – | Override the model. Gemini: gemini-3.1-flash-image (default), gemini-3.1-flash-lite-image, gemini-3-pro-image, gemini-2.5-flash-image. OpenAI: gpt-image-2 (default, best quality), gpt-image-1.5, gpt-… |
| n | integer | – | Number of images, 1-4 (default 1). Gemini generates sequentially, so n>1 is slower there. |
| output_path | string | – | Absolute path strongly recommended. Either a full file path (.png/.jpg/.webp) or a directory (a slugified filename is derived from the prompt). If omitted: $IMAGE_GEN_MCP_OUTPUT_DIR, then $CLAUDE_PRO… |
| prompt | string | yes | The edit instruction, e.g. "make the background transparent" or "restyle as a flat vector logo". |
| provider | string | – | Override the default provider. Call list_capabilities to see what is configured. |
| quality | string | – | OpenAI only, ignored by Gemini. Use low for cheap drafts. |
| return_image | boolean | – | Default false. When true, also returns the FIRST image as an inline MCP image block so you can see it without a Read. Large images can exceed the MCP output token limit; for 2K/4K prefer Read on the… |
| source_paths | array | yes | Absolute paths to existing input images (.png/.jpg/.jpeg/.webp). The first is the primary edit target; extras act as references. OpenAI accepts up to 16; Gemini works best with 1-3. |
No output schema declared.
No examples provided.
generate_image Generate image ~610
Generate one or more images from a text prompt using Gemini or OpenAI image models and save them to disk. Returns the absolute saved file path(s) plus provider/model metadata. Strongly prefer passing an absolute output_path inside the current project so the file lands where you can use it. Each image costs real API credits.

list_capabilities List image provider capabilities ~62
Report which image providers (gemini, openai) are configured in this server, the default provider and models, known model options, the output directory fallback, and any directory restriction in force. Call this first if unsure what is available or why a call failed.
Input schema present but exposes no named parameters.
