Install

Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

NPM package claude-wrap-mcp
Claude Code 
claude mcp add claude-wrap-mcp -- npx -y claude-wrap-mcp@0.1.0
JSON configuration (Claude Desktop, Cursor, VS Code) 
{
    "mcpServers": {
        "claude-wrap-mcp": {
            "command": "npx",
            "args": [
                "-y",
                "claude-wrap-mcp@0.1.0"

claude-wrap-mcp

An MCP server that lets an agent spawn and drive real Claude Code sessions, so Claude Code can run a fleet of Claude Code sub-agents. Built on claude-wrap.

Needs Node ≥ 18 and the claude CLI on your PATH. Headless sessions work everywhere; attaching to visible terminal windows is Windows-first.

Install

npm install -g claude-wrap-mcp
claude mcp add claude-wrap -- claude-wrap-mcp

Or in .mcp.json / claude_desktop_config.json:

{
  "mcpServers": {
    "claude-wrap": { "command": "npx", "args": ["-y", "claude-wrap-mcp"] }
  }
}

Tools

ToolWhat it does
claude_spawnStart a session in an absolute cwd. Returns a sessionId.
claude_askSend a prompt, wait for idle, return the transcript tail + parsed state.
claude_sendSend raw input (text / line / key) without waiting — for long tasks.
claude_statusBusy, mode, tokens, pending permission prompt, todos, last 5 tool names.
claude_tool_callsPage through the session's tool calls. Ids + names by default.
claude_tool_resultOne tool call by id: its args and result.
claude_snapshotThe rendered transcript lines.
claude_listEvery session, spawned here or discovered, with its backend, tmux attach command and lineage.
claude_resolve_permissionapprove / deny a pending permission prompt.
claude_stopShut down a session this server spawned or adopted (kills a tmux session).

There is a second family, claudep_*, that drives non-interactive claude -p sessions and returns structured JSON, tool calls, usage and cost.

Two things worth knowing:

  • Permission prompts are surfaced, not bypassed. When claude_ask or claude_status reports a permissionPrompt, answer it with claude_resolve_permission.
  • Tool calls are paged, not dumped. A status poll stays cheap because it carries only names; claude_tool_calls lists the rest and claude_tool_result fetches one call's output by id.

Sessions in tmux (Linux/macOS)

Set CLAUDE_WRAP_BACKEND=tmux in the server's environment (e.g. box-wide). claude_* sessions then run in tmux sessions, with no change to the MCP config:

  • they outlive this server: on shutdown it leaves them running, and anyone can tmux attach (the command is in claude_spawn / claude_list). Set CLAUDE_WRAP_TMUX_ON_EXIT=kill to stop them with the server instead;
  • any server adopts them: pass a tmux session name (as listed) as sessionId and the session is attached in-process, with full parsed state;
  • lineage: a session spawned from inside an agent that has TASK_ID / AGENT_ID set records that task and parent. claude_list shows it, and the registry entry (CLAUDE_WRAP_REGISTRY, one file per session when it's a directory) carries it for a supervisor.

See claude-wrap's README ("tmux backend") for the knobs and the entry format.
