Zovo Chord Chart Maker makes printable chord diagram PDFs for guitar (standard tuning), ukulele (G C E A) and piano. Pass the chords as a list (convert a pasted song or a photo of a chord sheet into chord names); use chord_sheet only for raw pasted text. Optional transpose, capo (or capo "auto"), left-handed diagrams and 6, 12 or 24 diagrams per page. Guitar and ukulele shapes are checked note by note.

Use this when the user wants a guitar chord chart printable, a ukulele chord chart, a piano chord chart, or chord diagrams for a song. Convert a pasted song or an uploaded photo of a chord sheet into the chords list (chord names like G, Em, F#m7, C/E); use chord_sheet only to pass raw pasted text. Draws one diagram per different chord as a print-ready PDF (US Letter or A4, 6, 12 or 24 per page) for guitar in standard tuning, ukulele (G C E A) or piano, with optional transpose, capo (or "auto"), and left-handed diagrams. Guitar and ukulele shapes are checked by their notes. Does not do alternate tunings, bass, tabs or notation.

Use this when the user asks how to play a chord on guitar, ukulele or piano ("how do I play F#m7b5 on ukulele", "easier way to play F"). Pass the chord names in chords. Returns up to 4 positions per chord (default 3), lowest on the neck first, with the frets, finger numbers and the note on each string, checked note by note, plus a PDF of the diagrams. For a whole song sheet use generate_chord_chart. Does not do alternate tunings or bass.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http zovo-chord-chart-maker-mcp https://chord-charts.zovo.one/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration

    }
  }
}

Claude Desktop

Open Claude Settings > Connectors > Add custom connector, enter this server URL and enable it for the conversation. This is a manual remote-connector handoff, not a desktop JSON configuration.
