Clarik is active. ``` Open Claude and start chatting. Clarik remembers everything. --- ## 💡 What It Does Clarik is an [MCP server](https://modelcontextprotocol.io) 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 | --- ## 🔧 All 20 Tools ### Free Tools (no license needed) | Tool | What It Does | |------|-------------| | `clarik_memory_learn` | Extract and store facts from conversations.

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? ```bash 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 1. Make sure the install completed successfully: `npx clarik status` 2. Restart Claude Desktop / Claude Code 3. 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: 1. Update Claude Desktop to the latest version 2. Avoid macOS beta releases if possible 3. Check `~/.clarik/` directory permissions ### License activation fails 1. Check your internet connection 2. Verify the key format: `CLARIK-XXXX-XXXX-XXXX` 3. Try again — Gumroad's API occasionally has brief outages 4. 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: ``` 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: ``` git remote URL → workspace root → package.json name ``` React project memories never appear in your Python project. --- ## Legal Clarik is an independent, community-built tool.
