A .NET console app + MCP server for encrypting, exporting, and importing GitHub Copilot CLI sessions.

CLI Usage:

# List sessions
dotnet run -- list

# Scan a session
dotnet run -- scan <session-id>

# Export session (encrypted)
dotnet run -- export <session-id> [output.zip]

# Import session
dotnet run -- import <path.zip> [target-copilot-root]

# Publish to GitHub
dotnet run -- publish <archive.zip> <owner> <repo>

# Run as MCP server
dotnet run -- --mcp

MCP Tools (for Copilot CLI integration):

• session_list — List all local sessions
• session_scan — Get session details
• session_export — Export encrypted session archive
• session_import — Import and decrypt session
• session_publish — Publish archive to GitHub release

Encryption:

• Uses AES-256 via EntityCrypt.Core
• Session ID serves as encryption key
• Sensitive data (code, events, files) encrypted at rest in SQLite
• Non-sensitive metadata (timestamps, types) stored in plaintext

• Termux (Android ARM64) or proot-distro Ubuntu
• .NET SDK 10.0+
• patchelf (for native Termux)
• gh CLI (for GitHub publishing)
