✨ Clarik

Clarity and memory for Claude. One install.

Claude forgets everything between sessions. Clarik fixes that.

Memory that persists · Context that stays lean · Sessions that never die

Get Started · All 20 Tools · How It Saves You Money · Go Pro

🚀 Quick Start

Terminal

npx clarik install

That's it. Clarik detects Claude Desktop and Claude Code, configures both, and starts working silently in the background.

Code

╔═══════════════════════════════════════╗
║           Welcome to Clarik           ║
║   Clarity and memory for Claude.      ║
╚═══════════════════════════════════════╝

✅ Detected: Claude Desktop
✅ Detected: Claude Code
✅ Checking compatibility...
✅ Done. Clarik is active.

Open Claude and start chatting. Clarik remembers everything.

💡 What It Does

Clarik is an MCP server that silently fixes the biggest problems developers have with Claude:

Problem	How Clarik Fixes It
🧠 Claude forgets everything between sessions	Persistent memory — facts, decisions, and gotchas survive forever
📄 Context fills up and quality drops	Intelligent injection — only the most relevant memories are loaded
💸 Repeating context wastes tokens	Token optimization — saves $47–73/month on API costs
🔄 Lost progress when context fills up	Checkpoints — save and resume exactly where you left off
🗂️ Memories from one project leak into another	Project isolation — each repo has its own memory space
⚠️ Claude edits files it shouldn't	Repo guard — protected files require your confirmation
🤔 Claude assumes instead of asking	Assumption checker — flags unverified claims

🛡️ Safe Modes

Clarik includes four safety modes to match your workflow:

Mode	Memory	Guards	Best For
Safe (default)	✅ On	✅ Active	Normal development
Strict	✅ On	🔒 Confirm all	Production code, sensitive repos
Minimal	❌ Off	❌ Off	Maximum privacy, quick tasks
Creative	✅ On	🟡 Relaxed	Prototyping, exploration

🖥️ CLI Commands

Terminal

npx clarik install          # Install into Claude Desktop + Claude Code
npx clarik activate KEY     # Unlock Pro tools with license key
npx clarik status           # Show plan, tools, savings, grace period
npx clarik upgrade          # Open clarik.dev/pro in browser
npx clarik uninstall        # Clean removal from all configs

🔒 Privacy & Data

Your data never leaves your machine.

All memory stored locally in ~/.clarik/
No telemetry, no analytics server, no cloud sync
No data transmitted except to Anthropic's API using your own API key
You own your memory files — they're plain JSON you can read, edit, or delete
License validation is the only network call (Gumroad, once per 24 hours)

❓ FAQ

Does Clarik send my code anywhere?

No. Everything stays on your machine. Clarik stores memories as local JSON files. The only network request is license validation via Gumroad (Pro users, once/day).

Does it work with Claude Desktop and Claude Code?

Yes. The installer detects and configures both automatically.

What happens when my context fills up?

Clarik can save a checkpoint of your current session — goal, progress, decisions, next steps. Start a fresh session and resume instantly with clarik_checkpoint_resume.

Can I use it offline?

Yes. Free tools work offline always. Pro tools have a 5-day offline grace period after your last successful license check.

Does it work on Windows?

Yes. Full Windows support with automatic cmd /c wrapper for stdio compatibility. Also works on macOS and Linux.

Will it conflict with other MCP servers?

No. All tools are prefixed with clarik_ to prevent naming conflicts.

Can I see what Clarik has memorized?

Yes. Use clarik_memory_list to see all stored memories, or browse the JSON files directly in ~/.clarik/projects/.

How do I delete my data?

Terminal

npx clarik uninstall        # Remove from Claude configs
rm -rf ~/.clarik/           # Delete all stored data

🔧 Compatibility

Platform	Status
macOS	✅ Fully supported
Windows	✅ Fully supported (cmd /c wrapper)
Linux	✅ Fully supported
Claude Desktop	✅ Auto-configured
Claude Code	✅ Auto-configured

Known Issues

macOS beta: MCP connections may be unstable on macOS beta releases. The installer will warn you if a beta version is detected.
Transport: Clarik uses stdio transport only. SSE and HTTP transports are not supported due to known MCP compatibility issues.

🔍 Troubleshooting

Clarik tools don't appear in Claude

Make sure the install completed successfully: npx clarik status
Restart Claude Desktop / Claude Code
Check that the MCP config file was written correctly:
- Mac: ~/Library/Application Support/Claude/claude_desktop_config.json
- Windows: %APPDATA%/Claude/claude_desktop_config.json
- Linux: ~/.config/Claude/claude_desktop_config.json

"Connection lost" or frequent disconnects

Clarik includes a 30-second heartbeat ping to keep the connection alive. If you still experience disconnects:

Update Claude Desktop to the latest version
Avoid macOS beta releases if possible
Check ~/.clarik/ directory permissions

License activation fails

Check your internet connection
Verify the key format: CLARIK-XXXX-XXXX-XXXX
Try again — Gumroad's API occasionally has brief outages
Pro tools work offline for 5 days after last successful check

📊 How Memory Works

What Clarik Learns

✅ Stack and framework choices ("We're using Next.js 14 with App Router")
✅ Architectural decisions ("Moved from REST to tRPC")
✅ File purposes ("lib/auth.ts handles JWT and sessions")
✅ Gotchas and warnings ("Don't use the v2 API — it's broken")
✅ User-confirmed facts

What Clarik Never Learns

❌ Thinking blocks (<thinking>, <antml-thinking>)
❌ Chain-of-thought traces
❌ Speculative guesses
❌ Content before a user correction

Memory Ranking

When recalling memories, Clarik scores each fact:

Code

score = (relevance × 0.5) + (recency × 0.3) + (importance × 0.2)

Only the highest-scoring facts are injected into context — never everything at once.

Project Isolation

Each project gets its own memory space, derived from:

Code

git remote URL → workspace root → package.json name

React project memories never appear in your Python project.

Clarik is an independent, community-built tool. It is not affiliated with, endorsed by, or associated with Anthropic PBC in any way.

Token cost savings are estimates based on typical developer usage patterns. Actual savings depend on your workflow, model choice, and usage volume.

Clarik stores all data locally on your device. No data is transmitted to any server except the Anthropic API using your own API key.
