The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
create_volta_note ~94
Creates a Volta secure note and returns a one-time URL. Use this to send sensitive information to a user — they open the link once, read it, and it's gone. Useful for sharing generated passwords, private keys, or any sensitive output.
| Name | Type | Req | Description |
|---|---|---|---|
| content | string | yes | The secret content to encrypt and store. Maximum 2,048 characters. Will be AES-256-GCM encrypted before leaving this machine. |
No output schema declared.
No examples provided.
read_volta_note ~92
Reads a Volta secure note and permanently destroys it. Call this when a user sends you a voltanotes.com URL containing sensitive information. The note content is returned once — it cannot be recovered after this call.
| Name | Type | Req | Description |
|---|---|---|---|
| url | string | yes | The full Volta note URL including the #fragment key, e.g. https://app.voltanotes.com/r/abc12345#encryptionKeyHere |
No output schema declared.
No examples provided.
