MCP: Connect Claude Code to Everything
Model Context Protocol is the most important AI coding extension in 2026 — one standard to connect AI with all your dev tools
What is MCP?
MCP (Model Context Protocol) is an open standard by Anthropic that lets AI assistants securely connect to external data sources and tools. With MCP, Claude Code can directly query databases, access GitHub, search docs, and control browsers without manual copy-paste.

}MCP Security Best Practices
MCP Servers have powerful system access — proper security configuration is critical
Least Privilege
Grant only the minimum permissions needed — avoid root or admin accounts
Verify Server Sources
Only use official or trusted community-maintained Servers — review source code and dependencies
Network Isolation
Restrict Server network access — prevent connections to untrusted external endpoints
Audit Logging
Enable MCP call logging and regularly review tool invocation records for anomalies
