Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.

      "maxItems": 1000,
      "description": "The exact voice IDs your agent has cached."
    }
  },
  "additionalProperties": false
}

get_voice

Get one voice's full profile: its VOICE.md, every source studied with a note on what it shows, the observations drawn from them, a handwritten example, the licence and the attribution line. Profiles are unofficial studies of public writing technique; the people named did not write or endorse them.

read-only

Argument	Type	Description
voice*	string	A voice slug such as elon-musk for the current edition, or an exact voice ID (slug@sha256:…) from search_voices.

Input schema (JSON)

{
  "type": "object",
  "required": [
    "voice"
  ],
  "properties": {
    "voice": {
      "type": "string",
      "pattern": "^[a-z][a-z0-9-]{0,60}(@sha256:[a-f0-9]{64})?$",
      "description": "A voice slug such as elon-musk for the current edition, or an exact voice ID (slug@sha256:…) from search_voices."
    }
  },
  "additionalProperties": false
}

get_voice_packet

Get the instructions for writing in one voice with your own model, for one format, length, platform, intensity and edge. The packet carries the full VOICE.md, an exact length target fitted to the platform's limit, and the rules that keep the user's own facts and identity. It opens with a line that replaces any earlier voice, so switching voices mid-conversation is one call.

read-only

Argument	Type	Description
edge	string	clean removes swearing, sexual and drug references; full keeps the voice's edge, never slurs or racism.
voice*	string	A voice slug such as elon-musk for the current edition, or an exact voice ID (slug@sha256:…) from search_voices.
format*	string	post (one standalone post), reply (answers the post being replied to), explanation (connected prose) or thread (several posts).
length	string	one-liner, short, standard or long; each maps to a measured range for the format.
platform	string	Where the draft will be posted: fits its character limit and whether it takes markdown.
intensity	string	light lets the user's own phrasing show; full writes completely in the voice.

Input schema (JSON)

search_voices

Search Silvertongue's famous writing voices by name, by lane (tech, celebrity, comedy, classics, politicians), or by what the writing should do: a roast, a launch post, a plain explanation, a speech. Each result gives the voice ID, its lane, what the voice does, what was studied, its strengths and limits, and its status. Omit the query to list every voice, featured voices first.

read-only

Argument	Type	Description
lane	string	Only voices in this lane.
limit	integer	Maximum results to return; defaults to 25.
query	string	A person's name, a lane, or what you want the writing to do. Omit to list every voice.
