# MCP Code Mode: `search_tools` and `execute_typescript`

_2026-09-23 · MCP_

By default the MCP server now lists two tools instead of one per operation. `search_tools` returns typed TypeScript declarations for the tools a connection can reach, and `execute_typescript` runs a short program that calls them in a sandbox, so an agent can batch several calls into one round trip.

Every call inside a program goes through the same scope checks, metering and audit as a direct tool call. A refused call throws an error inside the program carrying a stable code.
