Claude Context Sync
If you're running multiple Claude Code sessions in parallel and they keep stepping on each other's work, this server watches your session logs and provides six MCP tools to coordinate them. It automatically summarizes what each session is doing, detects when two sessions edit the same file or even the same function (supports TypeScript, Python, Swift, Go, Rust symbol detection), and lets you send messages between sessions without switching terminals. The summarization is lazy, only running when you call get_session_context or list_sessions, and it uses stratified sampling for large logs. Installation registers a conflict detection hook that alerts Claude when overlap happens. Useful if you context switch between architectural work and bug fixes, or coordinate with teammates who share the same codebase.

claude-context-sync
MCP server that automatically summarizes and shares context across parallel Claude Code sessions.
When you run multiple Claude Code sessions on different tasks, each session is unaware of what the others are doing. claude-context-sync watches your session logs, generates structured summaries on demand, and provides real-time file conflict detection and cross-session messaging.
Features
- Session context sharing — any session can see what others are working on
- File conflict detection — real-time alerts when multiple sessions edit the same file
- Symbol-level conflicts — detects shared function/class/interface edits (TypeScript, Python, Swift, Go, Rust)
- Cross-session messaging — send messages between sessions without switching terminals
- Lazy evaluation — zero cost when tools aren't called
- Auto-cleanup — tracked data is removed when sessions end
