Write one draft in a famous voice with Silvertongue's MCP server

Review criteria before you claim.
  • Dogfood the work. Run the skill or artifact on a real input and include the command, output, and receipt where requested.
  • Make the proof checkable. Use a sealed runx receipt, a public URL, or captured request and response evidence that a reviewer can inspect.
  • Keep claims tied to sources. Use real references, correct versions, and evidence for anything you assert.
  • Ship something with public or operator value. The reviewer should be able to explain why someone would use, link, merge, or learn from it.
  • Incomplete, private-only, or unverifiable submissions are returned with exact revision notes. Fix the packet and resubmit.

Context. Silvertongue is a library of famous writing voices, each studied from what the person actually published. Its MCP server is free and needs no account: your own AI fetches a voice and writes your draft in it. This bounty buys one real draft written that way, and your honest account of how it went.

The task. 1. Connect Silvertongue's MCP server to an AI app you use, at exactly this address: https://mcp.silvertongue.dev/mcp?ref=frantic-mcp-1&receipt=1 Claude Code: claude mcp add --transport http silvertongue "https://mcp.silvertongue.dev/mcp?ref=frantic-mcp-1&receipt=1" Codex: codex mcp add silvertongue --url "https://mcp.silvertongue.dev/mcp?ref=frantic-mcp-1&receipt=1" VS Code, Cursor, Claude Desktop or any app that takes an MCP server's URL works too. Use the address with everything after the question mark: that is what makes your receipt. 2. Ask your AI to use Silvertongue for something you actually want to send (a reply, a post, a message to a friend) in a famous voice, for example: Use Silvertongue to write my reply as Gordon Ramsay: I can't make it Friday. Name Silvertongue in the ask: without it, some AIs write the draft from memory and never fetch the voice. Your AI looks the voice up, fetches it and writes the draft. 3. After the draft, your AI shows a line: Receipt: https://runx.ai/r/<64 hex>. That link is your proof. If it doesn't appear, ask your AI to show the receipt line from Silvertongue's voice packet; if it never fetched one, ask again and name Silvertongue.

Deliver receipt_ref=<the https://runx.ai/r/... link> and report=<raw URL of your report>.

The report. Markdown at a public raw URL (a gist's raw link), as bullets: the app, its version and the model; the voice and exactly what you asked for; the draft exactly as your AI wrote it; whether it sounds like them, from 1 to 10, and why; one thing that confused you or didn't work, or none found and what you tried; one change you would make.

Nothing you publish mentions this bounty: no posts, issues or pull requests about it anywhere; your report describes your run.

Timing: the claim window is twelve hours. A receipt made before this bounty was posted does not count, and a receipt another claim already delivered is refused. One claim and one delivery per person.

It pays $1.

Deliverable: One draft written by your own AI in a Silvertongue voice fetched over the MCP server, delivered as receipt_ref (Silvertongue's receipt for the fetch) and report.

Acceptance
  • receipt_ref is the https://runx.ai/r/<64 hex> link shown after the draft: published by Silvertongue's key, venue silvertongue, subject mcp.voice_packet, made after this bounty was posted, and delivered by no other claim.
  • report is Markdown at a public raw URL, with at least five bullets covering: the app, its version and the model; the voice and what was asked; the draft exactly as written; a 1 to 10 score with a reason; one finding or none found with what was tried; one change.
  • The draft in the report answers what the report says was asked, in the voice it names.
  • Every finding is specific enough to act on without asking (the exact words asked, the app's setting, an error text); none found, with what you tried, is an honest answer.
  • No API key, token or password appears in any artifact.

Artifacts: `receipt_ref`, `report`

Claim window: 12 hours before release. Platform standing may grant longer, never shorter.

Returned for revision if: A receipt published by anyone but Silvertongue, a receipt for another subject, a receipt made before this bounty was posted or already delivered on another claim, a report with no draft, a draft that is not in the voice named, invented app versions, and a report that restates the docs instead of describing your run are returned for revision with the missing piece named.

Review gate: The machine floor has pinned the receipt to Silvertongue's key, venue silvertongue, subject mcp.voice_packet and the posting time. Open the receipt on runx.ai and confirm its time sits inside the report's timeline. Read the draft: it answers what the report says was asked, and reads as the named voice rather than a generic rewrite. Confirm the app named takes an MCP server by URL.
