HanoLab Voice Conversion does not always answer

Over the last week it answered 7.5% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.

Available tools 9

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

audio

list_audio

List recent audio uploaded through this connection. Use the exact audio_id, never a local path or an arbitrary URL.

conversions

list_conversions

Find recent conversions submitted with this connection. Use get_task to refresh a task. This does not start new tasks.

convert

convert_voice

Spend HanoLab credits to submit the prepared conversion ONLY after the user confirms its cost and budget. Reuse the exact quote_id after interruption: repeated calls return the original task without another debit. A failed task needs a separate user decision before a new quote.

credits

get_credits

Read the connected account’s plan and available credits. Does not purchase credits.

prepare

prepare_voice_conversion

Prepare a fixed quote for uploaded audio and a ready owned voice. No credits are spent. Explain estimated_credits, obtain the user’s budget and explicit confirmation, then use convert_voice with this exact quote_id.

profile

get_profile

Identify the HanoLab account connected to these tools.

task

get_task

Check an owned task and return completed audio links. Refreshes worker status and may persist completion or a failure refund. Poll about every 10 seconds; do not submit a new paid task while waiting.

upload

create_upload_link

Create a private one-hour browser upload link. Ask the user to open it, choose an audio file or MP4 and return here. Requires the same HanoLab account; no credits are spent. This tool cannot read local paths or ChatGPT attachments directly.

voices

list_voices

List the connected user’s own saved voices and whether they are ready. If none are ready, open voicelab to create one.

HanoLab Voice Conversion — questions

Answers built from our own checks of this server.

What can HanoLab Voice Conversion do?

It exposes 9 tools, read directly from the server on our last check. Among them: convert_voice, create_upload_link, get_credits, get_profile, get_task, list_audio and 3 more. 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 HanoLab Voice Conversion working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 3 of 91 checks got a reply (3.3%), average response time 887 ms. The bar chart above shows every period we have measured.

The registry lists HanoLab Voice Conversion as active — why does it not respond?

The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.

How do I connect HanoLab Voice Conversion?

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 HanoLab Voice Conversion need an API key?

No. HanoLab Voice Conversion completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 9 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is HanoLab Voice Conversion?

It answers our handshake in 887 ms on average, which is faster than 7% 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.

Is HanoLab Voice Conversion open source?

We cannot say either way: written in JavaScript and 0 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
