Management Scripts

# Setup everything (first time)
npm run setup

# Register all servers
npm run register

# Unregister all servers
npm run unregister

# Re-point the stable symlink after renaming or moving this repo
./scripts/relink.sh

Path independence

Claude Code stores an absolute command path per stdio server, so registrations would break every time this folder is renamed or moved. To avoid that, servers are registered under a fixed path — ~/.mcp/mcps/<Server>/start-mcp.sh — where ~/.mcp is a symlink to this repo. After a rename or move, run ./scripts/relink.sh once; no re-registration and no config edits needed. register-all.sh calls it automatically. Override the link location with MCP_LINK=/some/path.

Documentation

Each MCP server has its own README with detailed documentation:

• MySQL README
• Jira README
• GitHub README
• CodeReview README
• Atlassian README
• CloudWatch README
• AzureAD README
• Kafdrop README
• MSK README

Requirements

• Node.js: 25.2.1 (automatically installed by setup script)
• Claude Code: Latest version
• GitHub CLI: For GitHub and CodeReview MCPs (brew install gh)
• Atlassian CLI: For Atlassian and CodeReview MCPs
• AWS CLI: For CloudWatch MCP (credentials configured)

Security

• Never commit .env files to version control
• All .env files are in .gitignore
• API tokens and credentials are stored locally only
• Each MCP runs in isolated process

Introduction to MCP Servers

What in the Devil's name are those...?

Think of MCP servers as smart-ish middleware between the agent's tools and the agent. An agent is basically a glorified chat-bot with tools. You can create your own coding agent starting from Codellama or DeepSeek by adding a minimum of 4 tools: file reader/editor, shell client, web-clinet, debugger. Think of these as supplementary abilities, besides the chat-bot's skill of diplomatically serving you bullshit.

MCP stands for Model-Context Protocoll, a fancy-ass name for a framework that lets AI agents handle structured inputs (basically JSON), manage context across tasks, and produce more consistent, meaningful outputs.

Now, since you cannot modify the built-in tools that Claude Code or Gemini CLI ship with, you can extend these with your own: the mighty MCP servers.

Think of these as functions you can call. They're like little Lambdas or Google Functions, running locally. There's a plethora of them freely available, which may or may not come with massive security risks. Good luck with those. You can create them with Node, Python, whatever you fancy. You can ask your AI agent to build them for you. It's basically just a one-file project.

Setup: Create a small server app exposing one or more functions, like code_review(pull_request_id), then register the tool so that your agent can "see" them (usually with mcp add my-code_review-server --scope user /path/to/server). Verify with claude mcp list to ensure it shows " Connected".

Run with - every service differs: mcp__code_review_review 1234 (Claude) or cursor.agent.codeReview(pull_request_id) (you guessed it, Cursor) etc. You can also @-mention them to toggle on/off, or use /mcp to see all available tools from connected servers.

Pros: Scoped, accepts params, can authenticate and integrate with external services, very flexible

Cons: more complex, needs a repo to share with the team.

WHAT

Aspect	Knowledge Base	Driver / Runtime	Workflow	Tool (MCP Servers)	AI Coding Agent
What	Model (LLM)	API + Query Tool	Shortcuts: Skill/Command	Background dormant process	UI/CLI: AI orchestrator
Why	Store knowledge	Access information	Automate operations	External service as tool	Analyze, plan, do, test
How	Tokenize & Predict next	Run models, serve API	/cmd syntax calls MCPs	Listen → Execute → Retry	Select tools → iterate
Example	Qwen4, DeepSeek	Ollama, LM Studio	/commit git flow	mcp-github, mcp-mysql	Cloud/Local, CLI/IDE/UI

• AI Agents by Category

Interface	Cloud (paid/proprietary)	Local
CLI	Claude Code, Gemini-CLI, Codex	Goose, PicoClaw, OpenClaw
IDE / UI	Cursor, Windsurf, Antigravity, Cline	LM Studio, Comfy UI, Auto1111
IDE Extensions	Q, Rovo, MS Copilot, GH Copilot, CodeGPT	Continue
Browser	Bolt, Lovable, Vercel v0, Replit	HuggingFace Spaces, Codespaces

WHY

Anthropic's baby, widely adopted. It's a standardized protocol that connects AI models and coding assistants to external tools and services in a structured, cost-friendly way.

• Because you don't wanna:

  • Copy-paste credentials and secrets into chat willy-nilly.
  • Manually describe API responses a zillion times per day
  • Explain your coding slave what and how to use every single time

• You want:

  • Secure, sandboxed access to tools
  • Structured tool descriptions
  • Automatic tool selection by AI based on task
  • Scalable across multiple AI platforms / agents

HOW

Core Pattern: Tools That Return Minimal, Structured Data

An MCP Server wraps external services (GitHub, databases, APIs) as tools, returning Minimal, Structured Data Typical Structure: ├── tools.js # Define what tools do (name, description, input schema) ├── handlers.js # Implement tool logic (call API/service, parse output) ├── index.js # Wire it up (Server → ListTools → CallTools) └── .env # Keep your passwords and tokens safe (use .gitignore as well)

Core Pattern: Context Window Optimization

Principle	Goal	How
Precise Descriptions	AI understands purpose	"Get PR details" not verbose explanation
Structured I/O	Prevent errors & min tokens	{title, branch} not raw API response with metadata/headers/status
Minimal Result Sets	Keep context lean	LIMIT 100 not all 10k rows
Clear Error Messages	Fast failure recovery	{error: "reason", suggestion: "fix"}

Real Result: GitHub PR queries drop from 2000-10k tokens → 300-800 tokens (75%+ savings).
