NoonFlow v0.5.1 Release Notes

Release Date: 2026-04-18

Overview

v0.5.1 is an enhancement release focused on MCP server management experience upgrade and dashboard optimization.

Building on the v0.5.0 brand rename (Monolith → NoonFlow), this release upgrades the existing MCP server configuration page and officially exposes it in the sidebar, replaces the non-functional Memory archive card on the dashboard, and fixes worktree branch refresh delays and cost model card data source issues.

Highlights

1) MCP Server Management Page — Redesigned & Officially Exposed

The MCP configuration page already existed but had a basic UI (simple list + Tabs layout) and was not exposed in the sidebar, making it hard for users to discover. v0.5.1 redesigns it and officially opens the entry:

• Stats overview: 4-stat card strip at the top (Total / stdio / HTTP / SSE) for a quick glance at server distribution
• Grouped cards: Servers grouped by type (stdio / HTTP / SSE), each group with icon, title, and count badge; cards show server name, type badge, command/URL preview, and env var key preview
• Search & filter: Search by server name or command content, with a dedicated empty state for no matches
• View toggle: List / JSON Config views, preserving the ability for advanced users to edit raw JSON
• Delete confirmation: Confirmation dialog before deleting a server to prevent accidental removal
• Action feedback: All add/edit/delete operations now show toast notifications for success/failure, replacing the previous console.error-only approach
• Interaction hints: Cards show edit icon + right arrow on hover, guiding users to click for editing

The overall style is unified with Skills, Hooks, and Agents pages using AutomationHeader + grouped card layout.

2) Sidebar — MCP Entry Officially Opened

• MCP navigation item opened: Exposed under the Automation group (Skills / Hooks / Agents) with CubeIcon, linking to /mcp, labeled "MCP" in both English and Chinese
• Costs entry removed: Removed /costs from the Monitor group (DollarCircleIcon), as cost info is already covered by CostByModelCard on the dashboard

3) Dashboard: Memory Card Replaced with MCP Card

The Memory archive card in the SmallCardsSection called /api/memory/archives, which was never implemented and always showed 0. v0.5.1 replaces it with an MCP servers card:

• Data source: /api/plugins/mcp
• Link target: /mcp (MCP management page)
• Display: Server name + type (stdio / HTTP / SSE)

4) CostByModelCard Data Source Fix

Switched the cost model card's data source from /api/usage/stats to /api/sessions/stats, using token counts and session counts instead of unreliable cost fields for better data accuracy.

5) Worktree Branch Refresh Optimization

Added immediate default worktree branch detection on the cache hit path, preventing the issue where branch name changes required a full reconcile before being reflected in the sidebar.

User-Visible Changes

After upgrading to v0.5.1, users will typically notice:

• MCP server configuration page upgraded from a basic list to a professional management interface with stats, grouping, and search, now officially accessible from the sidebar
• Dashboard's fourth small card changed from the non-functional Memory archive to a useful MCP server overview
• Sidebar now provides direct access to the MCP configuration page
• Worktree branch names refresh faster in the sidebar after switching branches
• Cost model card on the dashboard shows more accurate data

Compatibility & Migration

• No breaking data migrations
• Local data directory remains ~/.noonflow/
• Default database remains noonflow.db
• Frontend and Electron shell version aligned to 0.5.1

Upgrade Recommendations

• If you use MCP servers to extend AI capabilities, upgrading to v0.5.1 is strongly recommended for a significantly improved MCP management experience
• If you care about dashboard data accuracy, upgrade to get the corrected cost model data
• If you use NoonFlow with multi-branch worktrees, branch name refresh will be more responsive after upgrading

Verification Checklist

Key scenarios to verify before final release:

• MCP page: add / edit / delete servers, JSON config editing, search filtering
• Dashboard: four small cards (Skills / Hooks / Agents / MCP) data display and navigation
• Sidebar: MCP navigation item present and navigable
• Worktree: branch name refresh in sidebar after switching branches
• Dashboard CostByModelCard data displays correctly
