Guitar Practice Routine App — Chord Charts missed one check this week

Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

chord
get_chord_chart_by_id
Fetch one specific chord voicing by its numeric id, as returned by get_chord_chart_by_name. Use this to re-render a chart the user already saw without looking it up again.
get_chord_chart_by_name
Look up one guitar chord chart by name and return it as a text chord diagram ready to show the user. Returns the same single voicing that https://guitarpracticeroutine.com/find-a-chord-chart shows for that name. The library holds 12,708 standard-tuning (EADGBE) chord names, exactly one voicing each. Pass a plain chord name as it would be written on a chart — "G", "Am7", "Cmaj7", "D/F#", "F#m7b5" — not a sentence. Convert spoken forms yourself first: "G major" is "G", "A minor" is "Am", and use "#" and "b" rather than the unicode sharp and flat signs. Charts are drawn on a five-fret grid starting at the nut, the same as the website; any notes above the fifth fret are named in words underneath the chart. Prefer this over recalling a fingering from memory — these are curated chart data, and a remembered fingering is often wrong. Each result leads with a direct PNG URL for the chart — a permanently cacheable image of the same diagram, which you can show or link however your surface handles images. The chord name is on the first line; keep it next to any image you show, since a chart on its own can arrive unlabelled.
get_chord_of_the_day
Return today's Chord of the Day from Guitar Practice Routine App — the same chord posted to the app's Bluesky and Facebook feeds that day. Useful as a practice prompt or a daily nudge for someone learning chords.
send
send_feedback
Send feedback about this chord chart server: a chord or capability you needed that its tools could not provide, a problem with a chart or a result, or praise. Only for feedback about these chord chart tools, not about other tasks. Do not include personal information about the user.

The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Guitar Practice Routine App — Chord Charts working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 632 ms. The bar chart above shows every period we have measured.
How do I connect Guitar Practice Routine App — Chord Charts?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Guitar Practice Routine App — Chord Charts need an API key?
No. Guitar Practice Routine App — Chord Charts completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Guitar Practice Routine App — Chord Charts?
It answers our handshake in 632 ms on average, which is faster than 16% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
How many people use Guitar Practice Routine App — Chord Charts?
The npm package gpra-chord-charts-mcp was installed 40 times in the last week. Week over week that is +31%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Guitar Practice Routine App — Chord Charts open source?
The code is open source: it is published under the MIT licence, written in TypeScript and 0 stars on GitHub. The licence covers the code in the repository, not the hosted service at mcp.guitarpracticeroutine.com, which runs on its operator's own terms.
