[BUG] MCP server argument list gets truncated when using claude mcp add

Environment

• OS: Windows with WSL2 (Linux 6.6.87.2-microsoft-standard-WSL2)
• Claude Code: Running inside WSL2 environment
• Shell: bash
• MCP Server: SQLite MCP server using uv package manager
• Path format: Mixed Windows/WSL mount paths (/mnt/d/...)

Bug Description

• The claude mcp add command truncates long argument lists
• Only the first argument is preserved, rest are lost
• Affects SQLite MCP server configuration specifically
• Workaround: Use shell script wrapper instead

Steps to Reproduce

From WSL command line at my project directory:
claude mcp add sqlite /home/phil/.local/bin/uv -- --directory
/mnt/d/servers/servers-archived-main/src/sqlite run mcp-server-sqlite --db-path /path/to/db.db

Expected behavior: All arguments should be preserved

Actual behavior: Only --directory is stored in config

1. Workaround: Shell script wrapper works correctly

Additional Context

• Issue occurs when using long argument lists with claude mcp add
• Arguments after --directory get completely dropped
• Same configuration works when manually created in .mcp.json
• Shell script workaround bypasses the parsing issue entirely
• WSL path mounting may be contributing to the parsing complexity
