What it does
An MCP server for one-time encrypted secret handoff between agents, machines, or people. It encrypts secrets locally using AES-256-GCM, stores only ciphertext on the server, and destroys the secret after the first successful retrieval. Intended for developers who need to pass credentials or secrets through a channel without leaving a persistent copy.
- Pass an API key or credential from one agent to another when they share no common secret store or account.
- Send a secret through a chat or log channel so the token becomes inert after it is read once.
- Confirm a one-time handoff occurred, because a replayed token visibly fails instead of silently serving the secret again.
Tools this server exposes
| Tool | Does |
|---|---|
| store_secret | Encrypts a secret locally and uploads the ciphertext to Slidingbox, returning a token that encodes both a server pointer and the encryption key. |
| retrieve_secret | Decrypts and returns the secret associated with a token exactly once, then destroys it on the server so subsequent reads return nothing. |
Before you enable it
An MCP server runs with whatever access you give it. Start with a development account rather than production, and check which tools the server exposes before you let an agent call them unattended.
