Best CLI tools

Wraps the real Claude Code TUI with a session lifecycle layer. Resumable non-interactive workflows, HTTP daemon for remote/headless control, ACP server for editor integrations (Zed, Toad). Drives your existing Claude Code install rather than reimplementing it - keeps skills, hooks, MCPs, and approvals intact.

Multi-agent runtime that spawns each Claude Code or Codex agent in its own git worktree and home directory. JSON-RPC subprocess control, task pooling, artifact storage. Solves the share-a-directory failure mode that breaks most multi-agent harnesses.

Wraps any command-line tool as a typed JavaScript API agents can call directly. Saves writing a custom MCP for every CLI you want to expose.

Local proxy that exposes your Claude Max or Pro subscription as an Anthropic-compatible API. No API key, no per-token billing - just point your tools at localhost.

Go CLI plus Kubernetes operator that builds, tests, and deploys MCP servers as native k8s workloads. Wraps server lifecycle in standard kubectl-style flows.

TypeScript CLI that runs unit tests against prompts: compare models, check outputs, track cost. Treats prompts as code that needs CI.

Simon Willison's plugin for the `llm` CLI that routes calls through an existing OpenAI Codex subscription. Lets you use Codex-tier models from any `llm`-aware tool.

Cross-platform CLI to search, install, and configure MCP servers across Claude Desktop, Cursor, Cline, Continue, Goose, and more. Includes router and profile features for routing requests across servers.

Go CLI that generates a compact codebase summary (~250 tokens) and auto-configures Claude Code, Cursor, and Aider with it. Replaces the agent's exploration phase with a single primer.

Lets agents interact with programs that expect a human at the keyboard - REPLs, debuggers, TUI apps - things bash pipes cannot reach. Fills the gap between shell and full computer-use.

Interactive terminal dashboard that breaks down where your AI coding tokens actually go. Surfaces the chat-vs-tool-use split most users get wrong.
