MCP server for Flux AI image generation
A Model Context Protocol (MCP) server for AI image generation and editing using Flux through the AceDataCloud platform.
Generate and edit stunning AI images with Flux models (flux-dev, flux-pro, flux-kontext) directly from Claude, Cursor, or any MCP-compatible client.
AceDataCloud hosts a managed MCP server ā no local installation required.
Endpoint: https://flux.mcp.acedata.cloud/mcp
All requests require a Bearer token. Use the API token from Step 1.
Connect directly on Claude.ai with OAuth ā no API token needed:
https://flux.mcp.acedata.cloud/mcpAdd to your config (~/Library/Application Support/Claude/claude_desktop_config.json on macOS):
{
"mcpServers": {
"flux": {
"type": "streamable-http",
"url": "https://flux.mcp.acedata.cloud/mcp",
"headers": {
"Authorization": "Bearer YOUR_API_TOKEN"
}
}
}
}Add to your MCP config (.cursor/mcp.json or .windsurf/mcp.json):
{
"mcpServers": {
"flux": {
"type": "streamable-http",
"url": "https://flux.mcp.acedata.cloud/mcp",
"headers": {

}Claude Code supports MCP servers natively:
claude mcp add flux --transport http https://flux.mcp.acedata.cloud/mcp \
-h "Authorization: Bearer YOUR_API_TOKEN"Or add to your project's .mcp.json:
{
"mcpServers": {

"type": "streamable-http",
"url": "https://flux.mcp.acedata.cloud/mcp",
"headers": {
"Authorization": "Bearer YOUR_API_TOKEN"
}
}
}
}Add to Cline's MCP settings (.cline/mcp_settings.json):
{
"mcpServers": {
"flux": {
"type": "streamable-http",
"url": "https://flux.mcp.acedata.cloud/mcp",
"headers": {
"Authorization": "Bearer YOUR_API_TOKEN"
}
}
}
}Add to your MCP configuration:
{
"mcpServers": {
"flux": {

# Install from PyPI
pip install mcp-flux-pro
# or
uvx mcp-flux-pro
# Set your API token
export ACEDATACLOUD_API_TOKEN="your_token_here"
# Run (stdio mode for Claude Desktop / local clients)
mcp-flux-pro
# Run (HTTP mode for remote access)
mcp-flux-pro --transport http --port 8000{
"mcpServers": {
"flux": {
"command": "uvx",
"args": ["mcp-flux-pro"],
"env": {
"ACEDATACLOUD_API_TOKEN": "your_token_here"
}
}
}
}docker pull ghcr.io/acedatacloud/mcp-flux-pro:latest
docker run -p 8000:8000 ghcr.io/acedatacloud/mcp-flux-pro:latestClients connect with their own Bearer token ā the server extracts the token from each request's Authorization header.
Add to your Cursor MCP configuration (.cursor/mcp.json):
{
"mcpServers": {
"flux": {
"command": "mcp-flux-pro",
"env": {
"ACEDATACLOUD_API_TOKEN": "your_api_token_here"
}
}
}
}Install the Flux MCP plugin from the JetBrains Marketplace, or configure manually:
{
"mcpServers": {
"flux": {
"url": "https://flux.mcp.acedata.cloud/mcp",
"headers": {
"Authorization": "Bearer your_api_token_here"
}
}
}
}For cloud deployment or shared servers:
mcp-flux-pro --transport http --port 8000Connect from clients using the HTTP endpoint:
{
"mcpServers": {
"flux": {
"url": "https://flux.mcp.acedata.cloud/mcp",
"headers": {
"Authorization": "Bearer your_api_token_here"
}
}
