CLI reference for `openclaw attach` (launch Claude Code with a scoped Gateway MCP grant)

You want Claude Code to use OpenClaw Gateway MCP tools

You need a temporary session-bound MCP grant for an external harness

Attach CLI

openclaw attach launches Claude Code with a strict temporary MCP config bound to one Gateway session.

openclaw attach
openclaw attach --session agent:main:telegram:123 --ttl 600000
openclaw attach --print-config

Options:

--session <key> binds the grant to a Gateway session. Defaults to the main session.
--ttl <ms> requests a positive grant TTL in milliseconds. The Gateway applies its own ceiling.
--bin <path> selects the Claude Code binary. Defaults to claude.
--print-config writes the temporary .mcp.json, prints the launch command and env, and leaves the grant live until TTL expiry.

The bearer token is passed through environment variables, not argv. OpenClaw launches Claude Code with --strict-mcp-config --mcp-config <path> so ambient Claude MCP servers do not join the attached session. Normal launches revoke the grant when the Claude Code process exits.
