MCP Server Sampling Configuration Overwrites Previous Entries Instead of Adding New Ones #264853
Description
Type: Bug
When configuring model access for MCP servers in VS Code Extensions > MCP Servers (right-click > Config Model Access > check models > save), the first server's settings are added to chat.mcp.serverSampling in settings.json. However, configuring a second server overwrites the previous entry instead of adding a new one.
Expected: Add new entries for each server.
Actual: Replaces existing entry.
