Claude Code Plugin Marketplace

A curated collection of specialized Claude Code plugins designed to enhance your development workflow with intelligent agents, skills, and commands.

Official claude code marketplace: https://github.com/anthropics/claude-code

Overview

This marketplace provides three comprehensive plugin collections:

• devops-infrastructure: Infrastructure as Code (IaC), CI/CD pipeline specialists, and database optimization experts for DevOps workflows
• software-engineering: Code review, debugging, documentation, license compliance, payment integration, and HTML-first frontend development tools
• go-specialist: Advanced Go 1.25+ development with modern patterns, concurrency optimization, and production-ready tooling (linting, GitHub workflows, GitLab CI, GoReleaser)

Each plugin includes proactive agents that automatically assist with their specialized domains, plus skills and commands to streamline common development tasks.

Adding this Marketplace

/plugin marketplace add sgaunet/claude-plugins

For local development, you can also link a local folder:

git clone git@github.com:sgaunet/claude-plugins.git

MCP Server Requirements

These plugins leverage Model Context Protocol (MCP) servers to provide powerful integrations with external services. You must install and configure these MCP servers before using the plugins.

Required MCP Servers

All three plugins depend on the following MCP servers:

1. perplexity-ai - AI-Powered Research

Repository: sgaunet/pplx

Provides AI-powered web search and question-answering capabilities through Perplexity AI.

Installation:

# Install from source
git clone https://github.com/sgaunet/pplx.git
cd pplx
go install

# Or download pre-built binary from releases

Configuration:

# Add to Claude Code MCP configuration
claude mcp add perplexity-ai -- pplx mcp-stdio

# Set environment variable
export PERPLEXITY_API_KEY="your-perplexity-api-key"

Environment Variables:

• PPLX_API_KEY - Your Perplexity AI API key (get from perplexity.ai)

---

2. gitlab-mcp - GitLab Integration

Repository: sgaunet/gitlab-mcp

Enables GitLab operations including issues, merge requests, projects, and CI/CD pipelines.

Installation:

# Install from source
git clone https://github.com/sgaunet/gitlab-mcp.git
cd gitlab-mcp
go install

# Or download pre-built binary from releases

Configuration:

# Add to Claude Code MCP configuration
claude mcp add gitlab-mcp -- gitlab-mcp

# Set environment variables
export GITLAB_TOKEN="your-gitlab-token"
# export GITLAB_API_URL="https://gitlab.com/api/v4"  # If self-hosted GitLab URL

Environment Variables:

• GITLAB_TOKEN - GitLab Personal Access Token with api scope
• GITLAB_API_URL - GitLab API endpoint (default: https://gitlab.com/api/v4)

Generate GitLab Token:

1. Go to GitLab Settings → Access Tokens
2. Create token with api scope
3. Copy and set as environment variable

---

3. github - GitHub Copilot Integration

Official GitHub Integration via GitHub Copilot MCP server (HTTP transport).

Configuration:

# Set environment variable
export GITHUB_TOKEN="your-github-personal-access-token"

Environment Variables:

• GITHUB_TOKEN - GitHub Personal Access Token with appropriate scopes

Generate GitHub Token:

1. Go to GitHub Settings → Developer Settings → Personal Access Tokens → Tokens (classic)
2. Create token with scopes: repo, read:org, workflow
3. Copy and set as environment variable

---

4. task-master-ai - Task Management & Validation

NPM Package: task-master-ai

Provides task management, validation, and TDD methodology compliance checking.

Configuration: The plugins include this configuration automatically. It will be installed via npx on first use.

No additional setup required - runs via npx -y task-master-ai

---

Environment Variable Setup

Add these to your shell profile (~/.bashrc, ~/.zshrc, or ~/.profile):

# Perplexity AI
export PPLX_API_KEY="pplx-xxxxxxxxxxxxxxxxxxxx"

# GitLab
export GITLAB_TOKEN="glpat-xxxxxxxxxxxxxxxxxxxx"
export GITLAB_API_URL="https://gitlab.com/api/v4"

# GitHub
export GITHUB_TOKEN="ghp_xxxxxxxxxxxxxxxxxxxx"

Reload your shell:

source ~/.bashrc  # or ~/.zshrc

Verifying MCP Server Installation

Test that each MCP server is installed and configured correctly:

# Test perplexity-ai
pplx --version

# Test gitlab-mcp
gitlab-mcp --version

# Test GitHub token
curl -H "Authorization: Bearer $GITHUB_TOKEN" https://api.github.com/user

# Test task-master-ai (will auto-install via npx)
npx -y task-master-ai --help
