MCP (Model Context Protocol) Complete Guide¶
The protocol for connecting LLM agents to external tools, data sources, and execution environments in a controlled way.
Pick a tab for your level and follow the steps.
What we learned from daily use
MCP unifies tool calls, retrieval, and execution behind a consistent interface. In production, permissions, auditability, and failure behavior matter the most.
Get the big picture, then build. Your first MCP server in 30 minutes.
Step 1 — Understand the big picture
- MCP Dashboard — Overview on one page
- What Is MCP (Hub) — Overview and quickstart in one place
Step 2 — First implementation
- Implementation Patterns (5-min) — Build with Claude Code, fastest path
- Custom Tool Implementation — Add custom features in 5 minutes
📝 Beginner advice: Skim the Dashboard first, then jump straight to Implementation Patterns to get hands-on.
Design patterns and Claude Code integration for production-grade usage.
Step 3 — Learn design patterns
- Multi-tool Orchestration — Dependency and state management patterns
- Request Handler Patterns — Building complex tools
Step 4 — Claude Code × MCP integration
- Claude Code MCP Integration — MCP integration design for extensibility
- Claude Code MCP Practical Guide — External data to real-time processing
- MCP Server Implementation — Add custom tools in 5 minutes
- Agent Swarms × MCP — MCP-powered agent swarm implementation
💡 Practitioner's tip: Understand design patterns before Claude Code integration. Multi-tool Orchestration is the core of MCP design.
Guardrails, remote servers, and Serena MCP for production quality.
Step 5 — Operate safely
- Guardrails Implementation — 3-layer defense model and error handling
- Remote Server Implementation — Security and performance optimization
- Code Execution Agent Design — Reduce token costs by up to 98.7%
Step 6 — Leverage Serena MCP
- Serena MCP Coding Agent — Free AI coding agent supporting 30+ languages
- Serena MCP Implementation Guide — Setup for Claude Code, Codex, and JetBrains
- Serena MCP Security Best Practices — Tool permissions and gradual access strategy
💡 For advanced users: Progress from Guardrails → Serena MCP to keep a consistent permission management mindset.
