ecc2cursor

Bring battle-tested Cursor rules, skills, agents, commands, and MCP servers from Everything Claude Code into your Cursor IDE setup — with a single command.

Zero config. Fully stateless. No hidden files, no persistent state. Just run it.

Why ecc2cursor?

Everything Claude Code (ECC) is a curated collection of AI coding configurations — rules for dozens of languages, reusable skills, specialized agents, and pre-configured MCP servers. It's built for Claude Code, but the patterns are universal.

ecc2cursor automatically translates and installs these configs into Cursor's format:

• Cursor Rules — coding standards for TypeScript, Python, Go, Java, Django, Spring Boot, and more
• Cursor Skills — reusable prompt-driven workflows (TDD, code review, security audit, planning, etc.)
• Cursor Agents — specialized subagents for build errors, refactoring, database review, E2E tests
• Cursor Commands — one-click actions for common workflows
• MCP Servers — pre-configured Model Context Protocol integrations

No manual copying. No format mismatches. Just npx ecc2cursor and pick what you need.

Quick Start

# npm
npx ecc2cursor

# bun
bunx ecc2cursor

This launches an interactive wizard that walks you through:

1. Picking a target directory (~/.cursor/ or project-level)
2. Choosing which categories to sync (agents, rules, commands, skills, contexts, hooks, MCP)
3. Selecting language rule sets
4. Picking MCP servers to install
5. Confirming and syncing

Non-Interactive Mode

# Sync everything with defaults to ~/.cursor/
npx ecc2cursor sync        # or: bunx ecc2cursor sync

# Sync to a specific directory
npx ecc2cursor sync --dir=./my-project/.cursor

# Preview what would be synced
npx ecc2cursor sync --dry-run

# Check what's installed
npx ecc2cursor status

# Remove all ecc-* files
npx ecc2cursor clean

# Sync without a prefix (use original file names)
npx ecc2cursor sync --no-prefix

Tip: All npx commands work with bunx too — just swap the prefix.

How It Works

ecc2cursor is fully stateless — it saves nothing to your machine beyond the synced files themselves.

1. Clone: Shallow-clones the ECC repo to a temp directory (2-3 seconds)
2. Translate: Converts Claude Code configs to Cursor-compatible formats
3. Install: Writes files to your .cursor/ directory (with an optional prefix)
4. Cleanup: Deletes the temp clone

Prefix and Detection

By default, files are named with an ecc- prefix (e.g., ecc-typescript, ecc-code-reviewer.md). The prefix is the manifest — ecc2cursor scans for prefixed files to detect what's already installed.

You can choose no prefix during the wizard or via --no-prefix to keep original file names. Note that without a prefix, auto-detection and prefix-based clean won't work — the wizard will run each time, and clean will only remove MCP servers.

What Gets Synced

| Source | Target (with prefix ecc) | Description | |--------|--------|-------------| | agents/*.md | .cursor/agents/ecc-*.md | Cursor subagents | | rules/<lang>/*.md | .cursor/skills/ecc-<lang>/ | Coding standards per language | | commands/*.md | .cursor/skills/ecc-*/SKILL.md + .cursor/commands/ecc-*.md | Full skills + thin command wrappers | | skills/*/SKILL.md | .cursor/skills/ecc-*/SKILL.md | Pass-through skill definitions | | contexts/*.md | .cursor/skills/ecc-ctx-*/SKILL.md | Mode-specific context prompts | | hooks/hooks.json | .cursor/skills/ecc-coding-standards/rules/*.md | Hook intent guidelines | | mcp-configs/ | .cursor/mcp.json | MCP server installations (no prefix) |

With --no-prefix, the ecc- portion is omitted (e.g., agents/code-reviewer.md, skills/typescript/).

Content Transforms

All synced content is automatically adapted:

• Path references (~/.claude/ → ~/.cursor/)
• Agent references (→ skill references with ecc- prefix)
• Command references (→ ecc- prefixed commands)
• Tool names (Bash → Shell, Edit → StrReplace)
• Claude Code terminology (→ Cursor)

Flags

| Flag | Description | Default | |------|-------------|---------| | --dir=PATH | Target .cursor/ directory | ~/.cursor | | --prefix=NAME | File prefix for all synced items | ecc | | --no-prefix | Use original file names without a prefix | - | | --dry-run | Preview changes without writing | - |

Requirements

• Node.js >= 20 or Bun
• Git (for cloning the source repository)
