Copilot CLI 1.0.49-0: MCP Search & Memory Scoping

TL;DR

• Experimental /mcp search command to discover and install MCP servers from registry
• Memory permissions now show scope (user vs. repository) explicitly
• Fixed plugin registration, tmux rendering, and wide character input handling

New

• /mcp search command — Experimental feature to search and install MCP servers directly from the registry without manual setup
• Tool search with deferred loading — Experimental support for lazy-loading MCP and external tools to improve startup performance
• "None" reasoning effort option — Disable model reasoning in the reasoning effort picker for faster responses when you don't need chain-of-thought
• COPILOT_PLUGIN_DIR_ONLY environment variable — Lock plugin discovery to --plugin-dir only, enabling deterministic plugin sets in CI/CD and reproducible environments

Improved

• Memory permission clarity — Scope labels now show who can access stored memories (user scope or specific owner/repo), with timeline entries displaying (for user) or (shared with repository collaborators)
• PowerShell 5.x compatibility — Reduced syntax errors on Windows by avoiding && chaining in legacy PowerShell environments

Fixed

• Scroll view text copying now joins soft-wrapped lines cleanly without extra newlines or indentation
• Cursor positioning in input fields handles wide characters (CJK, emoji) correctly
• Hooks (preToolUse, postToolUse, subagentStart, subagentStop) fire properly for sub-agent tool calls
• Plugins loaded via --plugin-dir now correctly register agents as available task(agent_type=...) subagents in prompt mode
• Memory storage respects available scopes when no repository context exists
• --plugin-dir and --additional-mcp-config now work in --server / --headless mode
• Content-filtered model responses display explanations instead of blank assistant turns
• PromptFrame UI renders correctly inside tmux when outer terminal is ghostty, WezTerm, or kitty
• MCP OAuth token lookups are correctly scoped to the active session
