Available tools 4

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

song

find_song_key

Look up the key, tempo (BPM) and typical vocal range of a well-known song by its title, in Tera Studio's song list (key and tempo from AcousticBrainz's analyses of the recording). Returns the key with its relative key, how many analyses agree on it, the BPM when they agree, an estimated range, and links to the song's page and to the key changer. Use it when someone names a song and asks its key or tempo, or whether it suits their voice. Pass semitones if they want it higher or lower. A song outside the list comes back as not found, with the key finder and key changer for a file they have.

find_song_key_and_tempo

Find the musical key (major or minor, with its relative key) and the tempo in BPM of a song file the person has. Opens a small Tera Studio tool where they choose the file; it is analysed in their browser and never uploaded. Use it when someone asks what key or BPM a song is in, or wants to know before singing, mixing or practising it. It reads only the file and doesn't identify or play songs; find_song_key looks up a well-known song by its title.

own

get_own_voice_song_instructions

Explain how to hear a song sung in the person's own voice with Tera Studio, and give them the link to start. They create an account on terastudio.co, sing for about a minute, add a song they have the rights to use, and hear it back in their voice. Use it when someone wants to hear themselves sing a song, make a cover in their own voice, or turn a song into a gift in their voice. It returns steps and a link and creates nothing. Tera Studio only uses the person's own voice: not for celebrity or other people's voices.

shift

shift_song_key

Move a song the person has up or down by up to 6 semitones, keeping its speed, so it fits their voice, and play it back. Opens a small Tera Studio tool where they choose the file; the change happens in their browser and nothing is uploaded. Use it when a song is too high or too low for someone. Pass semitones if they said how far (negative is lower); otherwise they choose in the tool.

Tera Studio — questions

Answers built from our own checks of this server.

What can Tera Studio do?

It exposes 4 tools, read directly from the server on our last check. Among them: find_song_key, find_song_key_and_tempo, get_own_voice_song_instructions, shift_song_key. 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 Tera Studio 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 286 ms. The bar chart above shows every period we have measured.

Did Tera Studio ever remove tools?

Yes. start_song_in_my_voice is no longer exposed — we recorded the date each one disappeared. A tool vanishing usually means a breaking change for anything that depended on it.

How do I connect Tera Studio?

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 Tera Studio need an API key?

No. Tera Studio 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 Tera Studio?

It answers our handshake in 286 ms on average, which is faster than 49% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
