Desktop app MCP tab shows 'No MCPs configured' despite MCP servers being connected (CLI works fine) #30104
Description
Bug Description
The Desktop app (v1.15.13) MCP tab shows "No MCPs configured" even though MCP servers are properly configured and connected when checked via CLI.
Environment
- Desktop App Version: 1.15.13
- OS: Windows (win32)
- Config Location:
~/.config/opencode/opencode.json
Steps to Reproduce
- Configure MCP servers in
~/.config/opencode/opencode.json - Open Desktop app
- Click on MCP tab in sidebar
- Shows "No MCPs configured"
Expected Behavior
MCP tab should display all configured MCP servers (memory, next-devtools, context7, ai-testing, laravel-boost).
Actual Behavior
MCP tab shows:
- "No MCPs configured"
- "MCP servers provide specialized tools and resources to the agent. Add MCP servers to extend capabilities."
CLI Verification (Works Fine)
opencode mcp list
Output:
✓ memory connected
✓ next-devtools connected
✓ context7 connected
✓ ai-testing connected
✓ laravel-boost connected
5 server(s)
opencode debug config shows all 5 MCP servers correctly in the resolved config.
Analysis
- CLI reads config from
~/.config/opencode/opencode.jsonand shows all MCP servers - Desktop app sidecar spawns on
http://127.0.0.1:XXXXXbut MCP tab shows nothing - Server log shows no MCP-related errors
- Renderer log shows no JavaScript errors related to MCP
- This appears to be a Desktop app TUI rendering bug, not a config issue

This issue might be a duplicate of existing issues. Please check:
All three describe the same root cause: the Desktop UI not reflecting MCP server state that the CLI resolves correctly in v1.15.13. Please consider consolidating into one of the existing reports.

Same issue here on Windows (v1.15.13). MCP servers configured in both
~/.config/opencode/opencode.jsonand project-levelopencode.json— CLIopencode mcp listshows them all as connected, but the Desktop app MCP tab shows "No MCPs configured".Confirmed that the MCP servers themselves work perfectly fine during actual agent sessions (they respond to tool calls). It's purely a UI rendering issue in the desktop app's MCP tab.
Also experiencing this on Linux — so it's cross-platform, not Windows-specific.

The same problem appears in macOS version of the app.

I'm getting the same issue. The issue was introduced in 1.15.13, when I downgraded back to the previous version everything went back to working.
