Install

How do I install the Sats4AI - Bitcoin-Powered AI Tools MCP server?

Sats4AI - Bitcoin-Powered AI Tools is a hosted endpoint at https://sats4ai.com/api/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
transcribe_translate ~317

Compound endpoint — one payment turns audio in any of 13 source languages into both a transcript AND a translation in any of 119 target languages. Perfect for WhatsApp voice messages in a language you don't speak (Yoruba → English), or recording a meeting in another language and reading it in yours. Auto-detects source if omitted. Async — returns requestId, poll with check_job_status(jobType='transcribe-translate'). Flat price covers STT + translation. Cheaper than calling transcribe_audio + translate_text separately for typical voice messages. Pay with Bitcoin Lightning — no API key or signup needed. Requires create_payment with toolName='transcribe_translate'.

NameTypeReqDescription
audioBase64stringyesBase64-encoded audio file
paymentIdstringyesValid payment ID (must be paid)
sourceLanguagestringOptional — auto-detected if omitted. Accepts ISO-639 codes for the 13 STT languages: en, zh, hi, es, ar, fr, pt, ru, de, ja, ko, it, nl. NOTE: only these 13 are transcribable — a wrong hint (or audio…
targetLanguagestringyesTarget language — English name (e.g. 'Spanish') or ISO-639 code (e.g. 'es', 'en-US'). 119 languages supported.

No output schema declared.

No examples provided.

translate_epub ~307

Translate a whole EPUB into another language and get an EPUB back. Every chapter is translated with its markup intact — headings, emphasis, footnote links, images and code stay where they were — the package language is retargeted and the table of contents is translated. 119 target languages; the target language picks the engine and the engine's row carries the price (same per-character rate as translate_text for that language, min 50 sats). Async — returns requestId, poll with check_job_status(jobType='translate-epub'), then get_job_result for the download url (temporary, 6h). Pay with Bitcoin Lightning — no API key or signup needed. Requires create_payment with toolName='translate_epub', characterCount (visible characters of the book) and targetLanguage; the real file is re-priced at execution and a short-pay is refunded with the exact amount to re-pay.

NameTypeReqDescription
epubBase64stringyesBase64-encoded EPUB (max 50 MB)
fileNamestringOptional original filename, used to name the download.
paymentIdstringyesValid payment ID (must be paid)
sourceLanguagestringOptional source-language hint. Omit to let the model read it from the text.
targetLanguagestringyesTarget language — English name (e.g. 'Spanish') or ISO-639 code (e.g. 'es'). Must equal the targetLanguage the payment was quoted with.

No output schema declared.

No examples provided.

translate_rare_language ~393

Translate into 452 languages, 251 of them NOT supported by ChatGPT, Claude or Gemini (29 of those 251 measured at fair quality or better against human references) — including Bhojpuri (~50M speakers), Maithili (~34M), Egyptian Arabic (~100M), Moroccan Arabic (~30M), Chhattisgarhi, Magahi, Manipuri, Kashmiri, Shan, Kachin, Awadhi, Tamazight, Crimean Tatar, Quechua, Nuer, Sango, plus indigenous and minority languages with no callable API anywhere. Runs MADLAD-400 (Apache-2.0). QUALITY VARIES AND IS PUBLISHED PER LANGUAGE: every language carries a measured tier — good (chrF++ >= 45 vs human reference translations), fair (32-45), unverified (no benchmark exists, untested, may be poor), experimental (known weak). The response repeats the tier so you can judge how much to trust it. GET https://sats4ai.com/api/l402/translate-rare-language for the full language list with tiers, or GET /api/languages. Unsupported languages are rejected BEFORE payment. For mainstream languages use translate_text instead — it is cheaper and more fluent. Priced 50 sats base + 0.002 sats/char (GPU). Pay with Bitcoin Lightning — no API key or signup. Requires create_payment with toolName='translate_rare_language'.

NameTypeReqDescription
paymentIdstringyesValid payment ID (must be paid). Price = 50 sats + 0.002/char.
targetLanguagestringyesMADLAD language code ('mag', 'arz', 'bho', 'hne') or English name ('Magahi', 'Egyptian Arabic'). Rejected before payment if unsupported.
textstringyesText to translate. Max 6000 characters.

No output schema declared.

No examples provided.

translate_text ~677

Translate text across 119 languages with high accuracy. The target language picks the engine: GPT-OSS 120B by default, or a higher-scoring model (Gemini) where one measurably beats it. Auto-detects source language. Privacy-preserving: no data stored. Pricing: 1 sat per 1,000 characters on the standard engine, minimum 1 sat per request; a routed language costs more. GET /api/languages returns the exact price, engine and measured chrF for every language, and the 402 always quotes the real amount before you pay. Language parameters accept English names ('Spanish', 'Chinese (Simplified)') or ISO-639 codes / locale tags ('es', 'en-US', 'pt-BR', 'zh-Hans'). Supported languages: Afrikaans, Albanian, Amharic, Arabic, Armenian, Assamese, Azerbaijani, Basque, Belarusian, Bengali, Bosnian, Bulgarian, Burmese, Catalan, Cebuano, Chichewa, Chinese (Simplified), Chinese (Traditional), Corsican, Croatian, Czech, Danish, Dari, Dutch, English, Esperanto, Estonian, Farsi, Fijian, Filipino, Finnish, French, Frisian, Galician, Georgian, German, Greek, Guarani, Gujarati, Haitian Creole, Hausa, Hawaiian, Hebrew, Hindi, Hmong, Hungarian, Icelandic, Igbo, Indonesian, Irish, Italian, Japanese, Javanese, Kannada, Kazakh, Khmer, Kinyarwanda, Korean, Kurdish, Kyrgyz, Lao, Latvian, Lingala, Lithuanian, Luganda, Luxembourgish, Macedonian, Malagasy, Malay, Malayalam, Maltese, Maori, Marathi, Mongolian, Nepali, Norwegian, Occitan, Odia, Pashto, Polish, Portuguese, Punjabi, Romanian, Romansh, Russian, Samoan, Scots Gaelic, Serbian, Sesotho, Setswana, Shona, Sindhi, Sinhala, Slovak, Slovenian, Somali, Spanish, Sundanese, Swahili, Swedish, Tajik, Tamil, Tatar, Telugu, Thai, Tigrinya, Tongan, Turkish, Turkmen, Ukrainian, Urdu, Uzbek, Vietnamese, Welsh, Wolof, Xhosa, Yiddish, Yoruba, Zulu. Pay per request with Bitcoin Lightning — no API key or signup needed. Requires create_payment with toolName='translate_text' and prompt (the text to translate).

No output schema declared.

No examples provided.

upscale_image ~199

Upscale images 2x or 4x with neural super-resolution. Uses Real-ESRGAN (ICCV 2021, PSNR 32.73dB on Set5 4x, 100M+ production runs). Recovers real detail from low-resolution images — not interpolation. Optional face enhancement. Stable endpoint — model upgrades automatically as SOTA evolves. 5 sats per image, pay per request with Bitcoin Lightning — no API key or signup needed. Requires create_payment with toolName='upscale_image'.

NameTypeReqDescription
face_enhancebooleanApply face enhancement during upscaling (default false)
imageBase64stringyesBase64-encoded image (PNG, JPEG, WEBP) or data URI
paymentIdstringyesValid payment ID (must be paid)
scalestringUpscale factor: 2x or 4x (default 4x)

No output schema declared.

No examples provided.

voice_bridge_say ~225

Inject audio into an open Voice Bridge call. Two modes: (1) text — we synthesize via OmniVoice TTS in any of 602 languages; (2) audio_base64 + encoding — bring your own audio (mulaw_8000 or pcm_l16_16000 for MVP). STT is automatically muted while we inject, so the agent doesn't hear itself. No additional payment — covered by the session deposit.

NameTypeReqDescription
audioBase64stringPre-rendered audio bytes, base64 (mode 2). Use with 'encoding'.
encodingstringEncoding of audioBase64. mp3/opus require ffmpeg (not yet wired in MVP).
languagestringLanguage override for this utterance (default: session language)
sessionIdstringyesSession ID from open_voice_bridge
textstringText to speak (mode 1). Uses OmniVoice TTS.
voiceDescriptionstringFree-form voice description for TTS (e.g., 'calm female voice')

No output schema declared.

No examples provided.

vote_on_service ~111

Vote for a planned service to be built next. Returns JSON: { success, slug, newVoteCount }. 1 sat per vote — multiple votes allowed. Call list_planned_services first to discover valid slugs and current vote counts. Highest-voted services get prioritized. Requires create_payment with toolName='vote_on_service'.

NameTypeReqDescription
paymentIdstringyesValid payment ID (1 sat, must be paid)
slugstringyesService slug to vote for (from list_planned_services)

No output schema declared.
