Share secrets securely using zKettle — a zero-knowledge, self-destructing secret sharing tool. Create, read, revoke, generate, and audit secrets via MCP tools. Secrets are encrypted client-side with AES-256-GCM; the server never sees plaintext. Use for credential sharing, API key rotation, temporary access grants, and secure dead drops.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Secret Sharing with zKettle Share passwords, API keys, tokens, certificates, and other sensitive data via self-destructing, one-time URLs. All encryption happens client-side — the server stores only ciphertext. ## Prerequisites This skill requires a running zKettle MCP server. If zKettle is not installed or configured, see the [zKettle README](https://github.com/benderterminal/zkettle) for installation and MCP setup instructions. zKettle also offers a CLI, HTTP API, and Web UI — refer to the README if the MCP tools are insufficient for a particular workflow. ## How It Works - Secrets are encrypted with AES-256-GCM on the client - The decryption key lives in the URL fragment (`#key`) — never sent to the server - Secrets auto-delete after a configurable view count or time limit - The server is zero-knowledge: it stores only ciphertext and metadata ## Tools ### `create_secret` Encrypt and store a secret, returning an expiring URL. | Parameter | Type | Required | Default | Description | |-----------|------|----------|---------|-------------| …

How to install
mdr add benderterminal/zkettle/secret-sharing@sha256:db547ae0413210b8The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
