Free / Pro / Max plans
Package manager egress is on by default, but allowlisting arbitrary domains is not allowed (as of July 2026). Instead, we recommend using the Maton MCP server, which doesn't require network allowlisting.
Team / Enterprise plans
Network egress is disabled by default. An organization owner must enable it:
- Open Settings → Capabilities → "Code execution and file creation."
- Select "Allow network egress to package managers and specific domains."
- Add
maton.aito the allowed-domains list.
Refer to Anthropic's network access in Claude for more details.
