Connect agents to MultiVoice MCP
Agents do not log in themselves. Configure the MCP URL; a human completes browser OAuth.
Paid actions always require a server-issued quote and confirmation_handle. The agent must show the total to the human before execute_create.
MCP URL
https://db.multivoice.ai/mcpWhat you can order via MCP
- Classic audiobook
order_type_id 1— Professional audiobook with multi-voice AI narration in Russian, German, English, French or Latvian. Results: audio per chapter. - Subtitles
order_type_id 4— Automatic subtitles from audio or video. language_from must be one of these ids from get_create_options languages[]: af am ar as az ba be bg bn bo br bs ca cs cy da de el en es et eu fa fi fo fr gl gu ha he hi hr ht hu hy id is it ja jv ka kk km kn ko la lb ln lo lt lv mg mi mk ml mn mr ms mt my nb ne nl nn no oc pa pl ps pt ro ru sa sd si sk sl sn so sq sr su sv sw ta te tg th tk tl tr tt uk ur uz vi yi yo zh. Other ISO codes (sm, zu, …) are rejected as invalid_create_payload. When recognition is ready (status 3/3), download six original-track files via get_artifacts / prepare_download: simple, speaker-labeled and full × SRT and VTT (artifact_type_id 115–120). - Transcription
order_type_id 5— Transcription of phone calls, lectures, meetings and webinars. Same language_from catalog as subtitles: af am ar as az ba be bg bn bo br bs ca cs cy da de el en es et eu fa fi fo fr gl gu ha he hi hr ht hu hy id is it ja jv ka kk km kn ko la lb ln lo lt lv mg mi mk ml mn mr ms mt my nb ne nl nn no oc pa pl ps pt ro ru sa sd si sk sl sn so sq sr su sv sw ta te tg th tk tl tr tt uk ur uz vi yi yo zh. - Dubbing
order_type_id 7— Dubbed audio or video. language_from (speech in the film) must be one of: af am ar as az ba be bg bn bo br bs ca cs cy da de el en es et eu fa fi fo fr gl gu ha he hi hr ht hu hy id is it ja jv ka kk km kn ko la lb ln lo lt lv mg mi mk ml mn mr ms mt my nb ne nl nn no oc pa pl ps pt ro ru sa sd si sk sl sn so sq sr su sv sw ta te tg th tk tl tr tt uk ur uz vi yi yo zh. languages_to must be de en fr lv ru (German, English, French, Latvian, Russian).
Subtitles and dubbing come in two modes: fully automatic without human review (human_check omitted or "self"; faster and cheaper), or reviewed by a native speaker (human_check = source language, human_translation_check = target languages; costs more and takes longer). The agent must ask the human which mode to use; the quote shows the price.
Download — type 4 subtitles
When speech recognition is ready (status 3, substatus 3), list files with orders.get_artifacts, then mint a short-lived URL with orders.prepare_download (scope artifacts:download). Original track only; empty cues and SyntOriginal rows are skipped. Range requests are not supported.

Agent rules
- Do not use GET on /mcp as transport (405 is normal). Responses to POST may be JSON or SSE-framed.
- Do not start stdio/npx wrappers. Do not call LLM/synthesis servers instead of MCP.
- Write only the URL into client config. Never insert tokens, passwords, CLIENT_API_KEY.
- Stop and ask the human to Connect / codex mcp login.
- Sell only order types 1, 4, 5 and 7. Types 2 and 3 are closed via MCP.
- Orders: orders.get_create_options → URL sources: sources.inspect; local files: sources.prepare_upload (basename + size + duration, never a path) → orders.prepare_create → show total to the human → orders.execute_create with quote_id, confirmation_handle and a new operation_id. For local files, after execute upload 10 MiB MD5 chunks to /mcp-uploads (scope uploads:write is granted automatically with orders:create), then poll uploads.get_status. Retry with the same operation_id does not create a second charge.
- Download type-4 subtitles with orders.get_artifacts then orders.prepare_download. Six original-track files: 115 simple SRT, 116 simple VTT, 117 speaker SRT, 118 speaker VTT, 119 full SRT, 120 full VTT. Ready at recognition status 3/3. Translated tracks are not in this catalog.
- Do not call prepare_action / execute_action (disabled).
- Wallet top-up: billing.prepare_topup with topup_amount (EUR). Show the amount to the human; return checkout_url. The human pays in the browser. This is not orders.execute_create and does not spend from the wallet.
- Language ids lowercase from get_create_options languages[] only. Example: ru, not RU. Codes such as sm are rejected.
- Tool names, JSON keys and shell commands stay English.
