Claude Code Configuration Hub (2026)

Every configuration guide for Claude Code in one place. MCP server setup, security settings, custom keybindings, environment variables, and project-level CLAUDE.md patterns.

Getting Claude Code Configuration Right

Claude Code is highly configurable, but the number of settings and configuration files can be overwhelming. Between CLAUDE.md project files, settings.json for global preferences, MCP server definitions, environment variables for API keys, and framework-specific configuration that Claude Code generates, there are dozens of knobs to tune. This hub organizes every configuration guide so you can find exactly what you need.

The most impactful configurations fall into three categories. First, project-level settings through CLAUDE.md and settings.json control how Claude Code behaves in your codebase. These determine which tools are allowed, what coding conventions Claude follows, and how it handles sensitive operations like file deletion or git commands. Second, MCP server configuration extends Claude Code with external tools for databases, project management, cloud infrastructure, and more. Correct MCP setup means Claude Code can read Linear issues, query production databases, and deploy to Kubernetes without leaving the terminal. Third, security configuration ensures Claude Code operates within boundaries that match your organization’s policies: disabling dangerous tools, restricting network access, and auditing permissions.

If you are setting up Claude Code for the first time, start with the configuration hierarchy guide to understand how global, project, and user settings interact. Then configure your MCP servers and set up proper security boundaries before giving Claude Code access to production systems.
