MCP tools · 2 exposed · ~186 tokens

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 →

Tool Tokens
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.

NameTypeReqDescription
contentstringyesThe 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.

NameTypeReqDescription
urlstringyesThe full Volta note URL including the #fragment key, e.g. https://app.voltanotes.com/r/abc12345#encryptionKeyHere
