AI coding assistants have fundamentally changed how we build and deploy web applications. But here's the thing—these assistants are only as powerful as the tools and context you give them. That's where the Model Context Protocol (MCP) comes in.
MCP is an open standard from Anthropic that lets AI models like Claude connect to external tools, data sources, and services through a standardised interface. Think of it as a universal language that allows your AI assistant to actually do things—from managing your GitHub repositories to querying databases and automating browser tasks.
With thousands of MCP servers now available, figuring out where to start can feel overwhelming. In this guide, we'll walk through the six MCP servers we consider essential for web developers, freelancers, and agencies—along with practical installation instructions and real-world use cases.
Let's dive in.
What Makes a Great MCP Server?
Before we get into specific recommendations, let's establish what separates a must-have MCP server from the rest:
- Trusted and maintained — Comes from a verified source with active development and security updates
- Real productivity gains — Solves actual problems in your workflow, not just novelty features
- Easy integration — Works seamlessly with popular AI tools like Claude Desktop, Claude Code, Cursor, and VS Code
- Clear documentation — You can get up and running quickly without extensive troubleshooting
With those criteria in mind, here are the six MCP servers every web developer should know about.
1. GitHub MCP Server — Repository Management Made Easy
What it is
The official GitHub MCP server allows your AI assistant to interact directly with GitHub repositories. It can read issues, review pull requests, check commit history, manage branches, and even create new files—all through natural language commands.
Why you need it
GitHub is at the centre of most development workflows. Instead of context-switching between your terminal, browser, and IDE, you can ask your AI assistant to handle repository tasks directly. Need to check if that bug is already documented? Ask Claude. Want to review the changes in a PR before merging? Just ask.
Installation
For Claude Desktop:
Edit your claude_desktop_config.json file:
- macOS:
~/Library/Application Support/Claude/claude_desktop_config.json - Windows:
%APPDATA%\Claude\claude_desktop_config.json
Add the following configuration:
{
"mcpServers": {
"github": {
"command": "npx",
"args": ["-y", "@modelcontextprotocol/server-github"],
"env": {
"GITHUB_PERSONAL_ACCESS_TOKEN": "ghp_your_token_here"
}
}
}
}
For Claude Code:
claude mcp add github --scope user -- npx -y @modelcontextprotocol/server-github
Then set your token as an environment variable:
export GITHUB_PERSONAL_ACCESS_TOKEN=ghp_your_token_here
Example usage
- "Show me all open issues in the deployhq/app repository"
- "What changed in the last 5 commits on the main branch?"
- "Create a new issue titled 'Update deployment documentation' with a description"
2. Context7 — Up-to-Date Documentation for AI Coding
What it is
Context7 is specifically designed to make AI assistants better at writing code. It injects up-to-date, version-specific documentation and code examples directly into the prompt context, ensuring your AI uses accurate information from actual libraries rather than potentially outdated training data.
Why you need it
We've all experienced the frustration of an AI assistant generating code with deprecated methods or incorrect syntax for the library version you're using. Context7 solves this "hallucination" problem by giving Claude real-time access to current documentation for thousands of libraries.
Installation
For Claude Desktop:
{
"mcpServers": {
"context7": {
"command": "npx",
"args": ["-y", "@upstash/context7-mcp@latest"]
}
}
}
For Claude Code:
claude mcp add context7 -- npx -y @upstash/context7-mcp@latest
Example usage
- "Using the latest Rails 7.1 documentation, show me how to set up Active Storage with S3"
- "What's the correct way to configure Tailwind CSS 4.0 with Vite?"
- "Show me the current Next.js 15 API for server components"
3. Filesystem MCP Server — Local File Access for Your AI
What it is
The Filesystem MCP server gives your AI assistant controlled access to read, create, edit, and organise files on your local machine. You specify which directories it can access, maintaining security while enabling powerful file management capabilities.
Why you need it
Whether you're organising project files, searching through logs, or having Claude help refactor code across multiple files, local file access is fundamental. This server turns your AI assistant into a capable file manager that understands context and can make intelligent decisions about file operations.
Installation
For Claude Desktop:
{
"mcpServers": {
"filesystem": {
"command": "npx",
"args": [
"-y",
"@modelcontextprotocol/server-filesystem",
"/Users/yourname/Projects",
"/Users/yourname/Documents"
]
}
}
}
For Claude Code:
claude mcp add filesystem -s user -- npx -y @modelcontextprotocol/server-filesystem ~/Projects ~/Documents ~/Desktop
Example usage
- "Find all Ruby files in my project that reference the User model"
- "Create a new directory structure for a Rails API project"
- "Read the README and summarise the setup instructions"
4. Puppeteer MCP Server — Browser Automation and Testing
What it is
The Puppeteer MCP server allows your AI assistant to control a headless Chrome browser. It can navigate websites, interact with page elements, take screenshots, generate PDFs, fill out forms, and run automated tests.
Why you need it
For web developers, the ability to automate browser tasks is invaluable. You can use it for scraping documentation, testing your deployed applications, generating visual regression screenshots, or automating repetitive web-based workflows. Particularly useful for agencies managing multiple client sites.
Installation
For Claude Desktop:
{
"mcpServers": {
"puppeteer": {
"command": "npx",
"args": ["-y", "@modelcontextprotocol/server-puppeteer"]
}
}
}
For Claude Code:
claude mcp add puppeteer -s user -- npx -y @modelcontextprotocol/server-puppeteer
Example usage
- "Navigate to our staging site and take a screenshot of the homepage"
- "Fill out the contact form on example.com and submit it"
- "Check if the login page loads correctly and capture any console errors"
5. PostgreSQL/Database MCP Server — Direct Database Access
What it is
Database MCP servers (like those from Supabase or Bytebase) allow your AI assistant to connect directly to your databases. It can explore schemas, write and execute SQL queries, manage records, and help you understand your data structure.
Why you need it
Instead of writing SQL queries manually or switching to a database client, you can ask Claude to query your data in natural language. This is especially powerful for debugging, data exploration, and generating reports. The AI can understand your schema and write optimised queries based on what you're trying to accomplish.
Installation
For Claude Code (using Bytebase DBHub):
claude mcp add db --transport stdio -- npx -y @bytebase/dbhub \
--dsn "postgresql://user:password@localhost:5432/myapp_development"
For Claude Desktop:
{
"mcpServers": {
"database": {
"command": "npx",
"args": [
"-y",
"@bytebase/dbhub",
"--dsn",
"postgresql://user:password@localhost:5432/myapp_development"
]
}
}
}
Example usage
- "Show me the schema for the deployments table"
- "Find all users who signed up in the last 30 days but haven't completed a deployment"
- "What are the most common error types in the deployment_logs table?"
6. Sequential Thinking — Step-by-Step Problem Solving
What it is
The Sequential Thinking MCP server helps your AI assistant break down complex problems into manageable steps. It's designed for debugging, algorithmic challenges, architectural decisions, and any task that benefits from structured reasoning.
Why you need it
Some problems are too complex to solve in a single prompt. Sequential Thinking enables Claude to work through problems methodically, documenting its reasoning at each step. This is particularly valuable for debugging tricky issues, planning refactoring projects, or working through deployment strategies.
Installation
For Claude Desktop:
{
"mcpServers": {
"sequential-thinking": {
"command": "npx",
"args": ["-y", "@modelcontextprotocol/server-sequential-thinking"]
}
}
}
For Claude Code:
claude mcp add sequential-thinking -s user -- npx -y @modelcontextprotocol/server-sequential-thinking
Example usage
- "Walk me through debugging why my deployments are failing on the production server"
- "Help me plan the migration from Heroku to a VPS with zero downtime"
- "Break down the steps needed to implement CI/CD for this project"
Getting Started: Prerequisites
Before installing any MCP servers, make sure you have:
- Node.js installed (LTS version recommended) — Download here
- Claude Desktop or Claude Code installed
- npx available in your PATH (comes with Node.js)
To verify your installation:
node --version
npx --version
After adding servers to your configuration, restart Claude Desktop or Claude Code for the changes to take effect.
Security Considerations
MCP servers are powerful tools that can access sensitive data and systems. Keep these best practices in mind:
- Limit file access — Only grant access to directories you actually need
- Use read-only database connections when possible
- Rotate API tokens regularly and never commit them to version control
- Review server sources — Stick to official and well-maintained servers
- Be cautious with network access — Understand what external connections a server might make
