MCP tools · 3 exposed · ~1,376 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
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).

NameTypeReqDescription
aspect_ratiostring–Gemini and OpenAI gpt-image-2 honor the ratio exactly. Older OpenAI models approximate: landscape -> 1536x1024, portrait -> 1024x1536, 1:1 -> 1024x1024.
backgroundstring–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_sizestring–Gemini 3.x models only (ignored by OpenAI; gemini-2.5-flash-image is fixed at 1024px). Default 1K.
input_fidelitystring–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.
modelstring–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-…
ninteger–Number of images, 1-4 (default 1). Gemini generates sequentially, so n>1 is slower there.
output_pathstring–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…
promptstringyesThe edit instruction, e.g. "make the background transparent" or "restyle as a flat vector logo".
providerstring–Override the default provider. Call list_capabilities to see what is configured.
qualitystring–OpenAI only, ignored by Gemini. Use low for cheap drafts.
return_imageboolean–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_pathsarrayyesAbsolute 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 ~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 ~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.

Common questions

What is the Image Gen MCP server?

Image Gen is an MCP server listed in the public MCP registry as com.nuverlabs/image-gen. Generate and edit images from your coding agent with Gemini and OpenAI, using your own API keys. This page covers its npm package (@nuver-labs/image-gen-mcp).

Is the Image Gen MCP server safe to use?

Image Gen scores 90 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 28 September 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

What tools does the Image Gen MCP server expose?

Image Gen exposes 3 tools: generate_image, edit_image, list_capabilities. Their descriptions and schemas cost roughly 1,376 tokens of context every time the server is loaded.

Is the Image Gen MCP server still maintained?

Image Gen is still listed as active in the MCP registry. We last reached this channel on 28 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

What licence is the Image Gen MCP server under?

Image Gen declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
