@icogenie/mcp

MCP (Model Context Protocol) server for IcoGenie. Enables AI agents like Claude to generate production-ready SVG icons programmatically.

Installation

npm install -g @icogenie/mcp
# or use directly with npx
npx @icogenie/mcp

Configuration

Claude Desktop

Add to your Claude Desktop configuration (~/Library/Application Support/Claude/claude_desktop_config.json on macOS):

{
  "mcpServers": {
    "icogenie": {
      "command": "npx",
      "args": ["-y", "@icogenie/mcp"]
    }
  }
}

Claude Code

The server works automatically when installed globally or via npx.

Authentication

On first use, the MCP server will:

1. Open your browser for authentication
2. Ask you to approve access
3. Save the session token to ~/.icogenie/config.json

Subsequent uses are automatic - the token is shared with the IcoGenie CLI.

CI/CD Environments

Set ICOGENIE_SESSION_TOKEN environment variable to skip browser authentication:

export ICOGENIE_SESSION_TOKEN="your-session-token"

Available Tools

Example Workflow

1. Check credits:

   check_credits()
   → { credits: 50, team: { name: "Personal" } }
   

2. Generate a single icon:

   generate_icon({ prompt: "notification bell icon", style: "outline" })
   → { sessionId: "abc123", preview: "...", creditsRemaining: 49 }
   

3. Refine if needed (two-phase):

   regenerate_icon({ sessionId: "abc123", index: 0, prompt: "Add a dot indicator" })
   → { candidates: ["...", "...", "...", "..."], regenToken: "tok_xyz", creditsRemaining: 48 }
   
   confirm_regeneration({ regenToken: "tok_xyz", selectedIndex: 1 })
   → { success: true, preview: "...", creditsRemaining: 48 }
   

4. Download final package:

   download_icon({ generationId: "abc123", outputPath: "./bell-icon.zip" })
   → { savedTo: "./bell-icon.zip" }
   

Bundle Workflow

1. Plan the bundle (free):

   normalize_bundle({ description: "e-commerce app icons", targetCount: 8 })
   → { icons: [{ name: "cart", ... }, ...], styleRecommendation: "outline" }
   

2. Review and generate (pass bundleId for traceability):

   generate_bundle({ icons: [...], style: "outline", bundleId: "bundle_abc" })
   → { bundleId: "bundle_abc", icons: [...], credits: { previewUsed: 8 } }
   

3. Download bundle:

   download_icon({ bundleId: "xyz789", outputPath: "./ecommerce-icons.zip" })
