Harness

List a harness's native built-in tools

Changed on

The native tools an agent harness (e.g. claude-code) runs INSIDE its sandbox — Bash, Read, Edit, Glob, Grep, WebSearch, and the like. Display-only: these execute via the harness's own agent loop and are NOT callable through MCPJam. Static published-package metadata; no project scope.
