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