What is the Leonardo.ai (Generative AI & Models) MCP Server?
Connect your Leonardo.ai account to any AI agent and take full control of state-of-the-art generative image production and custom AI models through natural conversation.
What you can do
- Generation Orchestration — Initiate asynchronous image generation requests defining precise prompts, model UUIDs, and dimensions directly from your agent
- Model Discovery — Enumerate global platform models (Phoenix, Kino XL) and your fine-tuned custom models to understand available inference capabilities
- Image-to-Image — Acquire secure presigned URLs to upload initial images for guided AI generation and reference-based transformations
- Precision Variations — Create unzoom context extensions and visual variations expanding previously generated images while maintaining structural consistency
- Inventory Audit — List recent user generations and retrieve absolute image URLs, prompts used, and exact hardware metadata securely
- User Metrics — Monitor active account metrics and token usage allocations to manage your generation budget and operational costs in real-time
How it works
1. Subscribe to this server
2. Enter your Leonardo.ai API Key
3. Start generating professional AI visuals from Claude, Cursor, or any MCP-compatible client
Who is this for?
- Digital Artists & Designers — iterate on visual concepts and model fine-tuning through natural conversation without manual dashboard searching
- AI Content Teams — automate the production of high-fidelity marketing assets and branded imagery across multiple projects
- Creative Directors — audit generation histories and monitor team credit usage to ensure optimized AI resource allocation

Frequently asked questions
Can I check the progress of my image generation through my agent?
Yes. Use the get_generation_status tool with the Generation ID provided when you started the request. Your agent will poll the Leonardo API and return the final image URLs and metadata once the process is complete.
How do I find which AI models are available for generation?
Ask your agent to list_platform_models or list_custom_models. It will return a list of available UUIDs and model names (like Phoenix or Kino XL), which are required when triggering a new image generation request.
Can my agent perform image-to-image transformations?
Absolutely. Use the upload_init_image tool to acquire a secure presigned URL for your source image. Once uploaded, you can command your agent to trigger a generation that uses that image as a reference for guided AI transformations.
How does LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
