MCP details?
what port does it run on? do i use the root or pass /mcp or something? so localhost:some_port/mcp or just localhost:some_port? what tools does it expose? how safe is it?
Are you referring to the 1Password MCP Server for Codex with 1Password Environments (beta)? If so, then the documentation on the MCP interface (or my ability to find it) is lacking. As far as I can tell having only just tried enabling it, there is nothing listening on a network interface. The MCP uses an abstract namespace domain socket, `@1PASSWORD_MCP`.
```
$ ss --numeric --listening --processes | grep 1PASSWORD_MCP
u_str LISTEN 0 4096 @1PASSWORD_MCP 497300 * 0 users:(("1password",pid=5445,fd=178))
```
You might get more and better help by posting in Developers.
As for how safe this particular domain socket is, I'd say about 0.712 ± 0.038.
