About
MCP server that spawns and drives Claude Code sessions via claude-wrap.
Security Report
This MCP server provides a well-structured interface for spawning and controlling Claude Code sessions via the claude-wrap library. The code demonstrates good security practices with input validation via Zod schemas, proper error handling, and no hardcoded credentials or malicious patterns. Minor code quality observations exist around broad error handling and subprocess spawning, but these do not pose significant security risks. Permissions align well with the server's stated purpose of session orchestration. Supply chain analysis found 2 known vulnerabilities in dependencies (1 critical, 0 high severity). Package verification found 1 issue.

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
| Tool | What it does |
|---|---|
claude_spawn | Start a session in an absolute cwd. Returns a sessionId. |
claude_ask | Send a prompt, wait for idle, return the transcript tail + parsed state. |
claude_send | Send raw input (text / line / key) without waiting — for long tasks. |
claude_status | Busy, mode, tokens, pending permission prompt, todos, last 5 tool names. |
claude_tool_calls | Page through the session's tool calls. Ids + names by default. |
claude_tool_result | One tool call by id: its args and result. |
claude_snapshot | The rendered transcript lines. |
claude_list | Every session — spawned here or discovered. |
claude_resolve_permission | approve / deny a pending permission prompt. |
claude_stop | Shut down a session this server spawned. |
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_askorclaude_statusreports apermissionPrompt, answer it withclaude_resolve_permission. - Tool calls are paged, not dumped. A status poll stays cheap because it
carries only names;
claude_tool_callslists the rest andclaude_tool_resultfetches one call's output by id.
