They're often framed as competitors. They're not — they cover different layers. Here's the boundary.\n\n`CLAUDE.md`\n\n: standing instructions, per repo\n[ CLAUDE.md](https://code.claude.com/docs/en/memory) is a file Claude Code reads automatically. It's the right home for\n\n**Good at:** durable rules that rarely change; zero setup; versioned with the code.\n\n**Where it stops:** it's static and per-repo. It's a poor fit for \"what did we decide this morning,\" which changes daily, and it doesn't cross repos or capture a decision *at the moment an agent makes one*. It also doesn't help two agents avoid editing the same file right now.\n\nGit already stores your code and its history, and commit messages/PRs explain *why a change happened*. Some teams try to extend this into a shared \"memory\" — a Markdown vault or changelog committed to a repo.\n\n**Good at:** it is, and should remain, the canonical record of the code itself. Attribution and history come for free.\n\n**Where it stops:** most coordination context has no diff to attach to — \"don't touch this module yet,\" \"we're standardizing on X,\" \"who's working on payments.\" Pushing that into Git turns coordination into a file that has to be pulled, merged, and resolved. Merge conflicts are exactly the thing you're trying to avoid, and a committed vault reintroduces them. Git is also poll-based: an agent only sees an update after a fetch, not the moment it's written.\n\nAn MCP memory server gives agents a small shared store they read and write through tools, live, across sessions and machines. [MCP is an open standard](https://modelcontextprotocol.io/docs/getting-started/intro) for connecting AI applications to external systems. This is the layer for **the decisions and context that never make it into a commit** — and, in some tools, for coordination primitives like file claims and a task board.\n\n**Good at:** capturing a decision the instant an agent makes it; serving it to a *different* agent on a *different* machine on connect; staying vendor-neutral (any MCP client — Claude Code, Cursor, Codex).\n\n**Where it stops:** it is not your code store. It shouldn't try to be Git, and a good one won't fetch or clone your repositories.\n\n`CLAUDE.md`\n\nThey compose. Keep code in Git, keep conventions in `CLAUDE.md`\n\n, and put the fast-moving team context — \"we decided v2,\" \"carol holds payments,\" \"is the API frozen?\" — in a shared MCP layer where every agent can read and write it.\n\n[Vibsync](https://vibsync.com/) is that MCP layer: durable team memory (`remember`\n\n/ `recall`\n\n), async agent-to-agent Q&A (`ask`\n\n/ `reply`\n\n), and file-claim + task coordination — one endpoint, vendor-neutral, bring your own model. It deliberately does **not** ingest your source; Git stays the source of truth. A decision one agent records is inherited by a fresh session on another machine, without anyone copy-pasting context.\n\nIf your team keeps re-explaining the same decisions to new Claude Code sessions, that's the gap this layer fills.
