Image Gen MCP Server

What this does

Image Gen exposes a set of tools to Claude over the Model Context Protocol. After you add it to claude_desktop_config.json (snippet above) and restart Claude Desktop, those tools become callable inside any conversation.

Requirements

This server needs the following environment variables to be set before it can run:

GEMINI_API_KEY
OPENAI_API_KEY
IMAGE_GEN_MCP_DEFAULT_PROVIDER
IMAGE_GEN_MCP_GEMINI_MODEL
IMAGE_GEN_MCP_OPENAI_MODEL
IMAGE_GEN_MCP_OUTPUT_DIR
IMAGE_GEN_MCP_ALLOWED_DIRS
IMAGE_GEN_MCP_TIMEOUT_MS
IMAGE_GEN_MCP_LOG_FILE

Set these via the env object in your MCP config (see claude_desktop_config.json snippet above).

How do I install Image Gen?

Run the Claude Code command in the install section to add Image Gen to Claude Code, or copy the ready-made config for your client from the install section on this page. Restart your client afterwards and the tools appear in your next conversation.

Which clients work with Image Gen?

This page carries setup and config for Claude Code, Claude Desktop, Cursor and VS Code. Any other MCP client that accepts a standard server config can connect to Image Gen as well.

Does Image Gen need an API key?

Yes. Before it can run, set these environment variables: GEMINI_API_KEY, OPENAI_API_KEY, IMAGE_GEN_MCP_DEFAULT_PROVIDER, IMAGE_GEN_MCP_GEMINI_MODEL, IMAGE_GEN_MCP_OPENAI_MODEL, IMAGE_GEN_MCP_OUTPUT_DIR, IMAGE_GEN_MCP_ALLOWED_DIRS, IMAGE_GEN_MCP_TIMEOUT_MS, IMAGE_GEN_MCP_LOG_FILE. They go in the env block of your MCP config.
