Claude Code v0.2.50

• New "project" scope for MCP servers: You can now add MCP servers to .mcp.json files and commit them to your repository. This allows teams to share MCP server configurations as part of their project.

  claude mcp add --scope project

• Memory type selector: When creating memories, you can now choose between three types:
• Project Memory: Shared in the project repository (stored in CLAUDE.md)
• Example: "Run lint with the following command after major edits: npm run lint"
• Local Memory: Private to you in this project (stored in CLAUDE.local.md)
• Example: "Use my sandbox URL for testing: https://myapp.local"
• User Memory: Available in all your projects (stored in ~/.claude/CLAUDE.md)
• Example: "Don't add new comments when editing code"

The memory selector UI provides arrow key navigation and clear descriptions of each memory type's scope.

• Enhanced Jupyter notebook cell editing: New dedicated UI for notebook cell operations with better visual feedback
• Supports insert, delete, and replace operations on notebook cells
• Shows cell type (code or markdown) and index information
• Provides syntax-highlighted previews of cell contents
• Displays diffs for cell replacements

• Automatic git operation analytics: The CLI now tracks when you perform git commits and create pull requests through the bash tool, providing better insights into your workflow patterns.

• Better support for files with spaces: The bash tool now properly handles file paths containing spaces by automatically quoting them

Example:

  cd "/Users/name/My Documents"  # Correctly handled
  python "/path/with spaces/script.py"  # Correctly handled

• Refined keyboard shortcuts: The input system has been optimized with better handling of escape sequences and control keys

• New token threshold warnings: The system now provides warnings when approaching token limits to help manage long conversations

• Removed several internal memory management functions that were replaced by the new memory type selector
• Removed unused debugging and configuration variables
• Consolidated import statements for better module organization

• Streamlined the CLAUDE.md file discovery system to support the new three-tier memory architecture
• Improved error handling for file operations
• Better organization of keyboard input handling code

Note: The previous version (v0.2.49) renamed MCP server scopes:

• Previous "project" scope → now "local"
• Previous "global" scope → now "user"

This version (v0.2.50) introduces a new "project" scope that allows committing MCP configurations to repositories.

• Fixed issues with notebook cell editing UI layout
• Improved handling of special characters in file paths
• Better error messages for invalid MCP scope specifications
