  --env OPENROUTER_API_KEY=sk-or-v1-xxx \
  -- npx -y mcpimg

Or create .mcp.json in your project root:

{
  "mcpServers": {
    "image-gen": {
      "command": "npx",
      "args": ["-y", "mcpimg"],
      "env": {
        "OPENROUTER_API_KEY": "sk-or-v1-..."
      }
    }
  }
}

Cursor

Edit ~/.cursor/mcp.json:

{
  "mcpServers": {
    "image-gen": {
      "command": "npx",
      "args": ["-y", "mcpimg"],
      "env": {
        "OPENROUTER_API_KEY": "sk-or-v1-..."
      }
    }
  }
}

Claude Desktop

      "env": {
        "OPENROUTER_API_KEY": "sk-or-v1-..."
      }
    }
  }
}

OpenCode (by SST)

Edit ~/.config/opencode/opencode.json or opencode.json in project root:

{
  "mcp": {
    "image-gen": {
      "type": "local",
      "command": ["npx", "-y", "mcpimg"],
      "environment": {
        "OPENROUTER_API_KEY": "sk-or-v1-..."
      },
      "enabled": true,
      "timeout": 120000
    }
  }
}

Charm Crush

Add to crush.json in your project root:

{
  "mcp": {
    "image-gen": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "mcpimg"],
      "env": {
        "OPENROUTER_API_KEY": "sk-or-v1-..."

Edit mods.yml (mods --settings):

mcp-servers:
  image-gen:
    command: [npx]
    args:
      - -y
      - mcpimg
    env:
      - OPENROUTER_API_KEY=sk-or-v1-...

Any MCP-compatible agent

This server uses stdio transport (JSON-RPC over stdin/stdout). Any agent that supports MCP stdio can use it:

npx -y mcpimg

# Required environment variables (at least one)
OPENROUTER_API_KEY=...    # OpenRouter (default)
TOGETHER_API_KEY=...      # Together AI
REPLICATE_API_TOKEN=...   # Replicate
FAL_KEY=...               # fal.ai

Using Multiple Providers

Set multiple API keys to use different providers:

export OPENROUTER_API_KEY="sk-or-v1-..."
export TOGETHER_API_KEY="..."
export FAL_KEY="..."

Then specify the provider when generating:

generate_image(prompt="a cat", provider="together", model="black-forest-labs/FLUX.1-schnell")
