* refactor(mcp): extract MCP server registry from onboard into shared module
Move _RECOMMENDED_MCP_SERVERS, _install_pip_package, and
_pip_install_hint from config/onboard.py into mcp/registry.py as a
shared MCPServerEntry dataclass and registry functions. This enables
reuse by the new /install-mcp command and marketplace integration.
* feat(mcp): add /install-mcp command for browsing and installing MCP servers
Interactive browser for MCP servers (built-in registry + EvoSkills
marketplace), supporting three modes:
- /install-mcp — interactive tag filter + checkbox selection
- /install-mcp <name> — direct install by name or tag pre-filter
- /install-mcp file.yaml — import servers from arbitrary YAML file
Also available as /mcp install and EvoSci mcp install. Includes TUI
browser widget (MCPBrowserWidget) mirroring the skill browser UX.
* chore(tavily): conditionally pass tavily_search when TAVILY_API_KEY is set
* fix(tui): Enter key detection for /install-mcp
- Fix message handler names: Textual converts MCPBrowserWidget to
mcpbrowser_widget (not mcp_browser_widget), so Confirmed/Cancelled
messages were never received by the app
- Distinguish empty selection from cancel in result handling
* chore(widgets): stop auto-advancing cursor on Space toggle in browser widgets
* style: linter
* refactor(mcp): simplify MCP registry to marketplace-only
Remove built-in server list and arbitrary YAML import — all server
definitions now come from the EvoSkills marketplace (mcp/*.yaml).
Onboarding filters by the `onboarding` tag instead of a hardcoded list.
* refactor(mcp): consolidate /install-mcp into /mcp install
Remove standalone /install-mcp command — use /mcp install as the
single entry point. CLI adapter now delegates logic to the shared
InstallMCPCommand class, keeping only the questionary UI layer.
* chore(cli): rm reference to yaml import
