Add Model Context Protocol (MCP) server integration to extend AI agent
capabilities with external tools. This allows users to configure MCP
servers (stdio, SSE, HTTP) in global settings and have agents use them.
Note: MCP servers are currently configured globally. Per-project MCP
server configuration is planned for a future update.
Features:
- New MCP Servers settings section with full CRUD operations
- Import/Export JSON configs (Claude Code format compatible)
- Configurable permission settings:
- Auto-approve MCP tools (bypass permission prompts)
- Unrestricted tools (allow all tools when MCP enabled)
- Refresh button to reload from settings file
Implementation:
- Added MCPServerConfig and MCPToolInfo types
- Added store actions for MCP server management
- Updated claude-provider to use configurable MCP permissions
- Updated sdk-options factory functions for MCP support
- Added settings helpers for loading MCP configs
- Added new endpoints for terminal settings: GET and PUT /settings to retrieve and update terminal configurations.
- Implemented session limit checks during session creation, returning a 429 status when the limit is reached.
- Introduced a new TerminalSection in settings view for customizing terminal appearance and behavior, including font family, default font size, line height, and screen reader mode.
- Added support for new terminal features such as search functionality and improved error handling with a TerminalErrorBoundary component.
- Updated terminal layout persistence to include session IDs for reconnection and enhanced terminal state management.
- Introduced new keyboard shortcuts for terminal actions, including creating new terminal tabs.
- Enhanced UI with scrollbar theming for terminal components.
