Desktop Commander MCP
wonderwhy-er
MCP server that gives Claude terminal access, file-system search and diff-based file editing on your local machine.
Key features
- Terminal Control: Runs shell commands, streams output back to Claude and lets the model iterate on real command results.
- File-system Search: Grep and glob across the workspace so Claude can locate the exact files or symbols relevant to a task.
- Diff-based File Editing: Applies precise, reviewable edits to files instead of overwriting whole files, minimizing accidental damage.
- Cross-platform: Works on macOS, Windows and Linux — installs with a single npx command.
- Process Management: Start, inspect and stop background processes so long-running tasks (servers, watchers) stay under Claude's control.
- Scoped Access: Configurable allowed directories and blocked commands so users limit what Claude can touch.
- Claude Desktop Integration: Registered as an MCP server so it works out of the box with Claude Desktop and any other MCP-compatible client.
Best for
- Vibe coding on your laptop: Let Claude explore a real repo, run tests and apply small edits without leaving the desktop app.
- Legacy codebase exploration: Ask Claude to grep, cd around and summarize how modules connect in a project it has never seen.
- Local automation scripts: Have Claude write, execute and iterate on shell or Python scripts against real files.
- Debugging sessions: Reproduce a bug locally, run failing tests, and let Claude patch the file with a diff you can review.
- Non-developer power use: Non-coders use Claude Desktop to organize files, rename in bulk, and generate reports from local data.

Second Brain for AI
Rahil Patel
Self-hosted persistent memory layer that lets Claude, ChatGPT, Cursor, and any MCP client share the same evolving context.
Key features
- Cross-Tool Persistent Memory: One memory layer shared by Claude, ChatGPT, Cursor, Codex, and any MCP client.
- Semantic Recall: Retrieves memories by meaning rather than exact wording, so different phrasings still surface the right note.
- Memory Graph (v2): Memories link automatically or explicitly, and recall can follow hops to surface related context.
- Notion Sync: Connect a Notion workspace and shared pages sync into memory nightly or on demand, staying current as they change.
- Self-Hosted on Cloudflare Workers: Deploy to your own account in about two minutes — memory stays under your control, not a vendor's.
- MCP Tool Set: remember, append, update, recall, list_recent, forget — usable directly from any MCP client or the brain CLI.
- Graceful Degradation: If Vectorize is missing, recall falls back to keyword search with a clear notice and a /health endpoint reports index status.
- Dashboard with Graph View: Web dashboard for browsing memories, managing integrations, and exploring the memory graph visually.
Best for
- Consistent Assistant Context: Keep the same project background, preferences, and decisions across Claude, ChatGPT, and Cursor without repeating yourself.
- Team Knowledge Capture: Use the CLI or MCP tools to store product decisions or interview notes so any AI tool can recall them later.
- Notion-Backed Memory: Share Notion pages with the connection so meeting notes and specs are automatically retrievable by any AI client.
- Self-Hosted Compliance: Run memory in your own Cloudflare account when data cannot leave your infrastructure or be locked in one AI platform.
- Developer Journaling: Save decisions and rationale from your terminal (`brain remember`) and recall them from Cursor while coding.
- Research Continuity: Store leads, references, and open questions once and surface them across whichever assistant you're using that day.
