Context Sync

Local-first project memory for AI coding tools over MCP.

Context Sync gives an agent a persistent memory layer for a codebase:

• project identity and tech stack
• active work, decisions, constraints, and caveats
• structured file exploration
• git-aware context
• optional read-only Notion lookup

What It Does

Context Sync is built for session continuity. Instead of relying on a model to remember earlier conversations, it stores the project context that matters and makes it retrievable through a small MCP tool surface.

The current core tools are:

• set_project
• remember
• recall
• read_file
• search
• structure
• git
• notion

Install

Install globally:

npm install -g @context-sync/server

Auto-configuration runs during global install. After install, restart your AI tool.

If you install locally instead of globally, auto-config does not run. Use the manual config guide in docs/CONFIG.md.

Verify

Check that context-sync appears in your MCP tool list:

• Claude Desktop: open the tools list
• Cursor: open the tools list
• VS Code / Copilot Chat Agent mode: check tools
• Continue.dev: open the Continue panel
• Codex CLI: codex mcp list
• Claude Code: claude mcp list

If auto-config fails, use docs/TROUBLESHOOTING.md and docs/CONFIG.md.

Optional Notion Setup

Run the setup wizard if you want Notion integration:

context-sync-setup

or:

npx context-sync-setup

Notion support is intentionally read-only at the tool surface:

• notion({ action: "search", query: "..." })
• notion({ action: "read", pageId: "..." })

First-Time Workflow

Start every new session by setting the project first:

1. set_project({ path: "/absolute/path/to/project" })
2. recall()
3. structure({ depth: 2 })
4. read_file({ path: "src/index.ts" })
5. remember({ type: "decision", content: "Use SQLite for local storage" })

Recommended pattern:

• set_project once per project/session start
• recall to recover context
• structure and search to explore
• read_file for focused inspection
• remember when something should survive the current session

Git Integration

When you run set_project inside a git repository, Context Sync can install hooks for automatic context capture.

Installed hooks:

• post-commit
• pre-push
• post-merge
• post-checkout

Hooks are marked with Context Sync Auto-Hook, and existing hooks are backed up first.

The git tool supports:

• status
• context
• hotspots
• coupling
• blame
• analysis

Data And Config

Default locations:

• Database: ~/.context-sync/data.db
• Config: ~/.context-sync/config.json
• Install status: ~/.context-sync/install-status.json

Custom database options:

• CLI: context-sync --db-path /absolute/path/to/db
• Env var: CONTEXT_SYNC_DB_PATH

See docs/DATA.md for storage details.
