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 any MCP-capable agent
(Claude Code, Claude Desktop, Cursor, …) spawn and drive Claude Code sessions
— effectively turning Claude Code into an orchestratable sub-agent fleet. Built
on the claude-wrap library.
Requirements
- Node ≥ 18
- The
claudeCLI on yourPATH(the sessions run real Claude Code). claude-wrappulls the nativenode-ptyaddon, so a prebuilt binary or a C/C++ toolchain is needed at install time.- Spawning headless sessions works cross-platform; attaching to visible windows is Windows-first.
Install & register
npm install -g claude-wrap-mcp
# then, in Claude Code:
claude mcp add claude-wrap -- claude-wrap-mcp
Or via JSON config (.mcp.json / claude_desktop_config.json):
{
"mcpServers": {
"claude-wrap": { "command": "npx", "args": ["-y", "claude-wrap-mcp"] }
}
}
Once published, it's also discoverable in the MCP Registry as io.github.Alex-Kaff/claude-wrap-mcp.
Tools
| Tool | What it does |
|---|---|
claude_spawn | Start a headless session in an absolute cwd. Returns a sessionId. |
claude_ask | Send a prompt, wait for idle, return transcript tail + parsed state. Returns status:"busy" on timeout (not an error). |
claude_send | Send raw input (text / line / key) without waiting — for long tasks; then poll. |
claude_status | Parsed state: busy, mode, tokens, pending permission prompt, todos, tool calls. |
claude_snapshot | The rendered transcript lines. |
claude_list | All sessions — in-process (spawned here) and external (discovered windows). |
claude_resolve_permission | approve / deny a pending permission prompt. |
claude_stop | Shut down an in-process session. |
Permission prompts are surfaced, not auto-bypassed: when claude_ask /
claude_status report a pending permissionPrompt, resolve it with
claude_resolve_permission.
Control models
- In-process (primary): the server owns a
claude-wrapClaudeManagerand drives headless sessions directly — full parsed state and lifecycle. - External (Windows-first): sessions launched elsewhere (visible windows)
are discovered via the registry and driven over their pipe; parsed operations
are delegated to the
claude-wrap-injectbin. Best-effort;claude_stopis declined for instances this server did not spawn.
Develop
pnpm install
pnpm --filter claude-wrap-mcp build # tsup -> dist/ (ESM + .d.ts, shebang on the bin)
pnpm --filter claude-wrap-mcp test # vitest, in-memory MCP client against fakes
pnpm --filter claude-wrap-mcp inspect # @modelcontextprotocol/inspector on the built server
