Introduction

Creating a portfolio website shouldn't be hard. But as the creator of Renderer, a TOML-driven portfolio framework, I noticed users struggling with:

  • Understanding TOML configuration syntax
  • Finding relevant documentation
  • Validating their configurations
  • Getting started quickly

The solution? An AI assistant that truly understands the framework. Not a generic chatbot, but a specialized tool that knows every configuration option, can validate your code, and guide you from zero to deployed.

Enter the Model Context Protocol (MCP) — a game-changing standard for connecting AI assistants with external tools and data sources.

In this post, I'll walk you through building Renderer MCP Server, a complete AI assistant that makes portfolio creation effortless. You'll learn:

  • How MCP works and why it's revolutionary
  • How to build your own MCP server from scratch
  • How to integrate it with Claude Desktop
  • Real-world testing and deployment strategies

Let's dive in! 🚀

What is Model Context Protocol?

The New Standard for AI Interoperability

Model Context Protocol (MCP) is an open standard developed by Anthropic that enables AI assistants to securely access external tools, data sources, and services.

Think of it as "USB for AI" — just like USB standardized how devices connect to computers, MCP standardizes how AI connects to the world.

Why MCP Matters

Before MCP:

❌ Each AI tool had custom integration code
❌ Switching AI providers meant rebuilding everything
❌ No standard way to share tools across platforms
❌ Security and permissions were ad-hoc

After MCP:

✅ Write once, use with any MCP-compatible AI
✅ Standard protocol for tool communication
✅ Built-in security and permission model
✅ Growing ecosystem of shared tools

Key Components:

  1. MCP Client - The AI assistant (Claude Desktop, VS Code, etc.)
  2. MCP Server - Your custom tool server
  3. Tools - Individual capabilities you expose
  4. Resources - Data sources the AI can access
  5. Prompts - Reusable prompt templates

The Problem We're Solving

User Pain Points

When I launched Renderer, I saw users struggling with:

1. Steep Learning Curve

"How do I configure the home page?"
"What's the syntax for TOML arrays?"
"Where do I put my social media links?"
Enter fullscreen mode Exit fullscreen mode

2. Documentation Discovery

"I know this feature exists, but where's the doc?"
"How do I search across all documentation?"
"What are all the available configuration options?"
Enter fullscreen mode Exit fullscreen mode

3. Configuration Validation

"Why isn't my portfolio loading?"
"Is this TOML syntax correct?"
"What fields am I missing?"
Enter fullscreen mode Exit fullscreen mode

4. Time-Consuming Setup

"It took me 2 hours just to get started"
"I had to read all the docs first"
"Too much trial and error"
Enter fullscreen mode Exit fullscreen mode

The Vision

What if users could just ask for what they need?

User: "Create a portfolio for me with projects and resume"
AI: *Generates complete, valid configuration*

User: "Is my home.toml correct?"
AI: *Validates and suggests improvements*

User: "How do I add dark mode?"
AI: *Shows exact configuration with examples*
Enter fullscreen mode Exit fullscreen mode

This is what Renderer MCP Server enables.

Architecture Overview

System Design

Our MCP server follows a clean, modular architecture:

renderer-mcp-server/
├── src/
│   ├── index.ts              # Main server & routing
│   ├── types.ts              # TypeScript definitions
│   ├── constants.ts          # Tool definitions
│   ├── github.ts             # GitHub API client
│   └── tools/                # Modular tool implementations
│       ├── validator.ts      # TOML validation

Technology Stack

Core:

  • Runtime: Node.js 18+
  • Language: TypeScript 5.3+
  • Protocol: MCP via @modelcontextprotocol/sdk
  • Transport: stdio (standard input/output)

Integrations:

  • GitHub API: @octokit/rest for repository access
  • TOML Parser: toml for configuration validation
  • Markdown: marked for content processing

Why This Stack?

  1. TypeScript - Type safety prevents runtime errors
  2. Modular Design - Each tool is independent and testable
  3. stdio Transport - Simple, universal, no networking
  4. GitHub Integration - Direct access to documentation and examples

import { Server } from "@modelcontextprotocol/sdk/server/index.js";
import { StdioServerTransport } from "@modelcontextprotocol/sdk/server/stdio.js";
import { 
    CallToolRequestSchema, 
    ListToolsRequestSchema 
} from "@modelcontextprotocol/sdk/types.js";

// Initialize MCP Server
const server = new Server(
    {
        name: "renderer-mcp-server",
        version: "1.0.0",
    },
    {
        capabilities: {
            tools: {},

                }
            },
            required: ["config_type"]
        }
    },
    // ... more tools
];

// Handle tool listing
server.setRequestHandler(ListToolsRequestSchema, async () => ({
    tools: TOOLS,
}));

// Handle tool execution
server.setRequestHandler(CallToolRequestSchema, async (request) => {
    const { name, arguments: args } = request.params;

    try {
        switch (name) {
            case "get_config_example":
                return getConfigExample(args.config_type);
            // ... more cases
            default:
                throw new Error(`Unknown tool: ${name}`);
        }
    } catch (error) {
        return {
            content: [{
                type: "text",
                text: `Error: ${error.message}`
            }],
            isError: true
        };
    }
});

// Start server
async function main() {
    const transport = new StdioServerTransport();

Testing with Claude Desktop

Claude Desktop has native MCP support built-in. Here's how to use it:

Step 1: Install Claude Desktop

Download from: https://claude.ai/download

Available for macOS and Windows.

Step 2: Configure MCP Server

Find your config file:

  • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
  • Windows: %APPDATA%\Claude\claude_desktop_config.json

Add your server:

{
  "mcpServers": {
    "renderer": {
      "command": "renderer-mcp",
      "env": {
        "GITHUB_TOKEN": "ghp_your_token_here_optional"
      }
    }
  }
}
Enter fullscreen mode Exit fullscreen mode

Why the GitHub token?

Step 3: Restart Claude Desktop

Close and reopen the app. The MCP server will start automatically.

Step 4: Verify Connection

In Claude Desktop, you should see:

  • A small "🔌" icon or "MCP" indicator
  • "Renderer" listed in connected tools

Step 5: Start Using It!

Just talk to Claude naturally. Here are real examples:

Example 1: Generate Starter Template

You:

Create a portfolio starter template for me. 
My name is John Doe, GitHub is johndoe, 
and I want projects and resume sections.
Enter fullscreen mode Exit fullscreen mode

Claude (using MCP):

I'll generate a complete starter template for you using the 
Renderer MCP server.

*calls generate_starter_template tool*

Here's your customized configuration:

[Shows complete TOML configs for home.toml, social.toml, 
projects.toml, and resume.toml with your information pre-filled]

To use this:
1. Clone the Renderer repository
2. Copy these configs to the config/ directory
3. Run npm install && npm run dev
4. Your portfolio will be live at localhost:3000!
Enter fullscreen mode Exit fullscreen mode

Example 2: Validate Configuration

You:

Can you validate this TOML config for me?

[profile]
name = "Jane Smith"
tagline = "Full Stack Developer"

[hero]
title = "Hi, I'm Jane"
Enter fullscreen mode Exit fullscreen mode

Claude (using MCP):

Let me validate that for you.

*calls validate_toml_config tool*

⚠️ Configuration Issues Found:

1. Missing 'hero.subtitle' field (recommended)
2. Missing 'hero.show_cta' field (required)
3. Missing 'features' section

Here's the corrected version:

[profile]
name = "Jane Smith"
tagline = "Full Stack Developer"

[hero]
title = "Hi, I'm Jane"
subtitle = "Building amazing web applications"
show_cta = true
cta_text = "View My Work"
cta_link = "/projects.html"

[features]
show_about = true
show_skills = true
show_social = true
Enter fullscreen mode Exit fullscreen mode

Example 3: Learn Features

You:

How do I add dark mode to my Renderer portfolio?
Enter fullscreen mode Exit fullscreen mode

Claude (using MCP):

Let me search for that feature.

*calls search_renderer_features tool*

# Dark Mode in Renderer

Renderer includes automatic dark mode support!

## Configuration (config/home.toml)

[theme]
mode = "auto"  # Options: auto, light, dark
accent_color = "#0066cc"

## How it works:

- **auto**: Follows system preferences (recommended)
- **light**: Always light theme
- **dark**: Always dark theme

Users can also toggle themes manually with the theme 
switcher button that appears automatically.

The theme preference is saved in localStorage, so it 
persists across sessions.
Enter fullscreen mode Exit fullscreen mode

Example 4: Get Examples

You:

Show me an example of how to configure projects
Enter fullscreen mode Exit fullscreen mode

Claude (using MCP):

*calls get_config_example tool*

Here's a complete example for projects.toml:

# Projects Configuration

[[projects]]
title = "Renderer Framework"
description = "A TOML-driven portfolio system"
tags = ["JavaScript", "TOML", "HTML"]
repo = "https://github.com/username/renderer"
demo = "https://demo.example.com"
docs = "https://docs.example.com"
featured = true
company = "@MyCompany"

[[projects]]
title = "Another Cool Project"
description = "Building something awesome"
tags = ["TypeScript", "React", "Node.js"]
repo = "https://github.com/username/project"
featured = false

## Usage:
1. Copy this to config/projects.toml
2. Customize with your projects
3. Add more [[projects]] blocks as needed
Enter fullscreen mode Exit fullscreen mode

Real Workflow Example

Here's a complete real-world workflow:

User: "I want to create a portfolio. Help me get started."

Claude: "I'll help you create a portfolio with Renderer! First, let me generate a starter template."

Uses generate_starter_template

Claude: "Great! I've created custom configurations for you. Now let me show you the setup steps."

Uses get_setup_guide

Claude: "Here's what to do:

  1. Clone the repository...
  2. Copy these configs...
  3. Run these commands..."

User: "I added my projects but getting an error"

Claude: "Let me validate your configuration."

Uses validate_toml_config

Claude: "Found the issue! You're missing a comma on line 5. Here's the corrected version..."

User: "How do I deploy this?"

Uses get_setup_guide with level: "advanced"

Claude: "Here are your deployment options:

  1. GitHub Pages...
  2. Vercel (recommended)...
  3. Netlify..."

Testing with MCP Inspector

The MCP Inspector is a visual debugging tool for MCP servers.

Step 1: Install & Launch 

# Run the inspector (no installation needed)
npx @modelcontextprotocol/inspector renderer-mcp
Enter fullscreen mode Exit fullscreen mode

This will:

  1. Start your MCP server
  2. Launch a web interface
  3. Open your browser automatically

Step 2: Explore the Interface

The inspector has three panels:

┌──────────────────────────────────────────────────────┐
│  Left Panel       │  Center Panel    │  Right Panel  │
│  (Tools List)     │  (Input Form)    │  (Results)    │
├──────────────────────────────────────────────────────┤

const cache = new Map();
async function getCachedFile(path) {
    if (cache.has(path)) return cache.get(path);
    const result = await fetchFromGitHub(path);
    cache.set(path, result);
    return result;
}
Enter fullscreen mode Exit fullscreen mode

2. Error Messages

// Current: Generic error messages
// Better: Actionable, specific errors

// Instead of:
"Validation failed"

// Provide:
"Missing required field 'profile.name' in home.toml (line 5)"
Enter fullscreen mode Exit fullscreen mode

3. Progress Indicators

// Current: Silent processing
// Better: Show progress for long operations

async function longOperation() {
    console.error("Fetching documentation...");
    const docs = await fetchDocs();
    console.error("Processing results...");
    return processDocs(docs);
}
Enter fullscreen mode Exit fullscreen mode

Key Takeaways 💡
