Setup snapshot

git clone https://github.com/ZenUml/diagramly-mcp-serverless.git
  1. 1

    Setup complexity is MEDIUM. Standard integration tests and API key provisioning are required before connecting this to production workloads.

  2. 2

    Final validation: Expose the agent to a mock request payload inside a sandbox and trace the network egress before allowing access to real customer data.

npx wrangler deploy

4. Type Check

npm run type-check

API Endpoints

  • POST /mcp - MCP protocol communication endpoint
  • GET /health - Health check endpoint
  • OPTIONS /* - CORS preflight request handling

Built-in Features

Tools

Currently includes:

  • mermaid-to-image: Convert Mermaid diagrams to images
    • Parameters: diagramCode (string), imageType (optional: "png" | "svg")
    • Function: Converts Mermaid diagram code to PNG or SVG images using Kroki service

Prompts

Currently includes:

  • mermaid-flowchart: Convert content to Mermaid flowchart

Extension Guide

Adding New Tools

  1. Create a new tool file in src/tools/
  2. Define your tool following the ToolDefinition interface
  3. Add it to the toolRegistry in src/tools/index.ts

Example:

export const myNewTool: ToolDefinition = {
  name: "my-new-tool",
  description: "Description of what this tool does",
  inputSchema: {
    param1: z.string(),
    param2: z.number().optional()
  },
  handler: async ({ param1, param2 }) => {
    // Tool implementation logic
    return {
      content: [{
        type: "text",
        text: "Tool result"
      }]
    };
  }
};

Adding New Prompts

  1. Create a new prompt file in src/prompts/
  2. Define your prompt following the PromptDefinition interface
  3. Add it to the promptRegistry in src/prompts/index.ts

Example:

export const myNewPrompt: PromptDefinition = {
  name: "my-new-prompt",
  config: {
    title: "My New Prompt",
    description: "Description of what this prompt does",
    argsSchema: { content: z.string() }
  },
  handler: ({ content }) => ({
    messages: [{
      role: "user",
      content: {
        type: "text",
        text: `Your prompt template here: ${content}`
      }
    }]
  })
};
