Code Mode

Write and execute Bun scripts that call MCP tools programmatically — multiple calls on a single persistent connection, without returning to the LLM between each call.

When to use

• Multi-tool orchestration: 3+ MCP tool calls where intermediate results feed into subsequent calls
• Batch operations: Repeated calls with different parameters (e.g., process a list of items)
• Cross-server workflows: Combining results from different MCP servers
• Token-heavy tool sets: Servers with many tools (like figma-console's 63+) where loading all schemas wastes context

When NOT to use

• Simple single-tool calls → use the normal tool-call loop
• Tools that require interactive OAuth → authenticate via claude mcp first, then use code-mode
• Operations that need human approval between steps → use normal tool-call loop
