Claude Code Config Generator

Generate a complete Claude Code setup

Claude Code is configured through a few small files: settings.json (model, permissions, behavior), CLAUDE.md (the project context loaded into every session), and .mcp.json (Model Context Protocol servers). This tool builds all three from a short form, with copy and download buttons for each — no syntax to memorize and no invalid JSON.

Install Claude Code

npm install -g @anthropic-ai/claude-code

Or with the install script:

curl -fsSL https://claude.ai/install.sh | bash

What each file controls

• settings.json — the default model (Opus, Sonnet, Haiku, or Opus-in-plan-mode), the permission mode, allow/deny rules, transcript retention, and privacy hardening (disable telemetry, error reporting, and auto-update).
• CLAUDE.md — a short, high-signal description of your project: stack, commands, conventions, and guardrails. Claude Code reads it at the start of every session.
• .mcp.json — connects MCP servers such as Filesystem, GitHub, Context7, Playwright, Postgres, and Brave Search so the agent can use external tools.

Permission modes explained

• Default — Claude asks before editing files or running commands.
• Accept edits — file edits apply automatically; commands still prompt.
• Plan — a read-only mode that produces a plan before any changes.
• Bypass permissions — no prompts at all; only use in a sandbox you trust.

Allow and deny rules

Allow rules let trusted actions run without prompting (for example Bash(git:*) or Edit). Deny rules block sensitive paths and dangerous commands no matter what — common picks are Read(./.env), Read(./secrets/**), Bash(rm:*), and Bash(sudo:*).

Private, in-browser AI for CLAUDE.md

The optional AI assist writes a tailored CLAUDE.md from a plain-English description of your project. It runs entirely in your browser using WebGPU — your description is never uploaded, not even to us. A ready-made template is always available without it.

Frequently asked questions

Where do these files go?

Put settings.json in .claude/settings.json inside your project (or ~/.claude/settings.json for global defaults). CLAUDE.md and .mcp.json live in your project root and can be committed so the whole team shares them.

Is this official?

No — this is a free community tool that produces standard Claude Code configuration files. See the official documentation for the full settings reference.

Does it send my data anywhere?

No. Everything is generated locally in your browser, and the optional AI context writer also runs locally via WebGPU.
