MCP TemplateIO - Image Generation Tool

A Model Context Protocol (MCP) server built with mcp-framework that provides an image generation tool using Templated.io.

Overview

This template provides a starting point for building MCP servers with custom tools. It includes an example tool and instructions on how to add more tools, develop them, and publish them to npm. This README will guide you through the process of setting up, developing, and deploying your own MCP server.

Quick Start

# Install dependencies
npm install

# Build the project
npm run build

Available Tools

Templated Image Generator

This tool generates an image based on a template, given text and image URLs, using the Templated.io API.

Input Parameters:

• templateId: ID of the Templated.io template to use
• photoBgImageUrl: URL for the image to place in the “photo-bg” layer.
• bgYellowImageUrl: URL for the image to place in the “bg-yellow” layer.
• buildText: Text content for the “build” text layer.

Tool Development

Example tool structure:

import { MCPTool } from "mcp-framework";
import { z } from "zod";

interface MyToolInput {
  message: string;
}

class MyTool extends MCPTool<MyToolInput> {
  name = "my_tool";
  description = "Describes what your tool does";

  schema = {
    message: {
      type: z.string(),
      description: "Description of this input parameter",
    },
  };

  async execute(input: MyToolInput) {
    // Your tool logic here
    return `Processed: ${input.message}`;
  }
}

export default MyTool;

Adding Components

The project comes with an example tool in src/tools/ExampleTool.ts and the TemplatedImageTool.ts. You can add more tools using the CLI:

# Add a new tool
mcp add tool my-tool

# Example tools you might create:
mcp add tool data-processor
mcp add tool api-client
mcp add tool file-handler

Publishing to npm

1. Update your package.json:

   • Ensure name is unique and follows npm naming conventions
   • Set appropriate version
   • Add description, author, license, etc.
   • Check bin points to the correct entry file

2. Build and test locally:

   npm run build
   npm link
   mcp-templateio  # Test your CLI locally
   

3. Login to npm (create account if necessary):

   npm login
   

4. Publish your package:

   npm publish
   

After publishing, users can add it to their claude desktop client (read below) or run it with npx
