solstone.me

an address on the internet for your journal, so an agent you already use can read from it: Claude, Codex, goose, or anything else that speaks the Model Context Protocol. you turn it on, you connect an agent, and you choose what that agent may see.

your journal is always private, only yours.

an address for your journal

sol pbc runs the solstone.me relay in between, so your agent can find your journal without you running anything of your own. it's off until you turn it on, and you can turn it off from the journal at any time.

blind by construction

your own machine holds the private key and ends the encryption, so the relay can't read a byte of what passes through it. it keeps no record of what happened, only that something did.

what an agent gets

you choose what it may see: your whole journal, or only the facets you choose. it reads. it can't add, change or delete anything.

the public record is permanent

the address is public once it's issued, and stays public for good, even after you turn this off, cancel, or delete your sign-in. it's an identifier, not your data: eight random characters with nothing of yours in it.

you never have to pay us. your journal doesn't need sol pbc to be reachable. a tunnel that only passes the bytes through works today with nothing of ours in the path, whether you rent one or run your own on a machine you control. one warning: some free tunnels decrypt your traffic in order to move it. whoever runs one of those can read what your agent reads, and can reuse your agent's key to reach your journal as though they were it. a tunnel that only passes the bytes through will say so; if its documentation doesn't say, assume it ends the encryption. the solstone.me relay is convenience, never a privacy upgrade over a tunnel that only passes the bytes through.
