What's Wrong?

Title: /mcp slash command shows "No MCP servers configured" even when servers are connected

Description:
The /mcp slash command displays "No MCP servers configured" even though MCP servers are properly configured and connected.
Running claude mcp list correctly shows the servers as connected and working.

Steps to reproduce:

1. Configure an MCP server in a project's .claude.json under the mcpServers key
2. Open Claude Code with that project

1. Run claude mcp list in terminal
2. Observe: Server shows as "✓ Connected"

Expected behavior:
The /mcp slash command should display the same MCP servers as claude mcp list.

Environment:

• OS: Windows 11
• Claude Code version: (latest)
• MCP server: stdio-based Python server

Workaround:
Using claude mcp add CLI command to add the server instead of relying on .claude.json config makes the server visible in both
places.

What Should Happen?

Show a list of mcp servers available to claude code
