OneKey Gateway

Use One Access Key to connect to various commercial APIs. Please visit the [OneKey Gateway Keys](https://www.deepnlp.org/workspace/keys) and read the docs [OneKey MCP Router Doc](https://www.deepnlp.org/doc/onekey_mcp_router) and [OneKey Gateway Doc](https://deepnlp.org/doc/onekey_agent_router).

# gemini Skill

Use the OneKey Gateway to access tools for this server via a unified access key.

Quick Start

Set your OneKey access key:

export DEEPNLP_ONEKEY_ROUTER_ACCESS=YOUR_API_KEY

Common settings:

Tools

`generate_image_gemini`

Generates an image using the Gemini Image API.

Supported Models (aliases are internal):

The model parameter allows selection between available image generation models.

- "gemini-2.5-flash-image" (recommended default for stable, fast response).

- "gemini-3-pro-image-preview".

- "gemini-3-flash"

Aliases for these models are 'nano-banana 2.5' and 'nano-banana 3 Pro' respectively.

Please use 'gemini-2.5-flash-image' unless the user specifically requests the Gemini 3 model.

Args:

model: The image generation model to use (see supported models above). Defaults to "gemini-2.5-flash-image". Supports: 'gemini-3-flash', 'gemini-3-pro-image-preview', 'gemini-2.5-flash-image'

prompt: A detailed text description for the image to be generated.

image_name: The filename for the output image, can be a relative path. Defaults to "gemini_output_images.png".

output_folder: The optional absolute folder path provided by the user where the image will be saved. Do not use default server locations.

aspect_ratio: The aspect ratio of the generated image (e.g., '16:9', '1:1', '4:3'). Defaults to '16:9'.

image_size: The size/resolution of the generated image (e.g., '1K', '2K', '4K'). Defaults to '1K'.

Return:

Dict: Result dictionary containing image path, message, and success status.

output_result["image_path"]: str

output_result["image_url"]: str

output_result["message"]: str

output_result["success"]: bool

Parameters:

`generate_image_nano_banana`

Generate Image With Nano Banana

Args:

model: The image generation model to use. Defaults to "gemini-2.5-flash-image". Supported Models such as follows Google Gemini Doc, such as 'gemini-3-flash', "gemini-3-pro-image-preview", "gemini-2.5-flash-image", note that nano-banana is the alias name of the Gemini Image Model. Nano banana 3 Pro refers to Gemini 3 pro preview, and Nono Banana 2.5 refers to Gemini 2.5. Unless specified by user to use Gemini 3 model preview, general 'Neno Banana' image models, please use 'gemini-2.5-flash-image' for more stable and fast response.

prompt: A detailed text description for the image to be generated.

image_name: The filename for the output image, can be a relative path, such as "./new_gemini_image.png", etc. Defaults to "gemini_output_images.png".

output_folder: The optional absolute folder path provided by the user where the image will be saved. Do not use default server locations.

aspect_ratio: The aspect ratio of the generated image (e.g., '16:9', '1:1', '4:3'), defaults to '16:9'.

image_size: The size/resolution of the generated image (e.g., '1K', '2K', '4K'), defaults to '1K'.

Return:

Dict: output_result is the result dict of MCP returned

output_result["image_path"] = full_path: str

output_result["message"] = output_message: str

output_result["success"] = success: bool

Parameters:
