MiniMax Speech (T2A) vs Murf TTS API + MCP

MiniMax Speech (T2A) 38

Read as a model, as minimax-voice-cloning is. The newest dated change touching speech is the MCP servers' August update, minimax-mcp-js 0.0.18 on 21 August 2026, 77 days before 6 November, and Speech 2.8 dates from 23 January 2026 (20 of 30). No dated API entries in the last 90 days (0). Support by email and Discord, not tested (6 of 15). No official SDK for speech; the MCP servers expose text_to_audio and list_voices (8 of 15). The Python MCP server has tests and moved to version 2 of the MCP SDK in August, with no CI workflow (4 of 10). Total 38.

Murf TTS API + MCP 73

Read as a model. Newest changelog entry 2026-10-27 (List Voices takes a model), after Falcon 2.1 on 2026-10-19 (30). Seven dated changelog entries in the 90 days from 3 August, on 5, 9, 13, 15, 19, 22 and 27 October, plus murf-mcp 0.1.14 on 2026-08-20 (10). Gen2 streaming was switched off on 2026-10-05 after a 20 July notice that named only the 16 August deprecation date, and on 19 October falcon-2 began serving Falcon 2.1, announced the same day (0 of 10). Public changelog and a help centre (10 of 15). The Python SDK had no open issues on 1 October, per that check, not re-read on 1 November (8 of 10). Official SDK in Python only, 2.3.0 still the newest tag on 1 November, from 2026-03-05 (8 of 15). Fern-generated with a CI workflow, Python 3.8 and later (7 of 10). 30+10+0+10+8+8+7 = 73.

MiniMax Speech (T2A) 36

Model reading of the checklist, with training and retention in place of the least-privilege and injection lines. Plain API keys with no scopes found, and leaked keys may be disabled (20 of 30). The terms (effective 30 March 2026), as read for minimax-voice-cloning on 4 November, let MiniMax use input and generated content to operate, maintain, develop and improve its services, with no opt-out found, and the privacy policy rules out only training to profile or target consumers (5 of 20). The speech docs call every interface stateless, and no retention period for submitted text or generated audio was found (5 of 15). Responses carry usage_characters and a trace ID, with no audit log (6 of 15). No security.txt, disclosure policy, bug bounty or certification found (0 of 20). Total 36.

Murf TTS API + MCP 68

Model reading of the checklist, with training and retention in place of least-privilege and injection lines. One api-key header, plus a generate-token endpoint for short-lived client tokens. No key scopes found (23 of 30). The docs say customer text and audio never feed Murf's model training (20). Download links last 72 hours by the TTS overview and 24 hours by the Enterprise FAQ, and encodedAsBase64 returns audio with nothing stored, so zero retention is self-serve but not the default (10 of 15). The dashboard shows daily and monthly usage, not per-call logs (5 of 15). SOC 2 Type II, ISO 27001 and ISO 42001 on the security page. No security.txt, disclosure policy or bug bounty found (10 of 20).

MiniMax Speech (T2A) 20

No x402, MPP or L402 (0). Per-character prices for every speech model published without a login (20). No free allowance for synthesis is published (0). A person signs up in a browser and funds a balance (0). Total 20.

Murf TTS API + MCP 40

No x402, MPP or L402 (0). Falcon 2 at 1 cent per 1,000 characters and Gen2 at $0.03, published in the docs without a login (20). 100,000 free characters with no time limit behind a Get Free API Key button. We found no card step in the docs or FAQ (20). A person signs up in a browser to get the key (0).

MiniMax Speech (T2A) 75

Atlassian Statuspage at status.minimax.io with a Text-to-Speech component (20). Its history, re-read on 6 November, shows three incidents in the 90 days from 8 August, all titled elevated errors and labelled major, 22 minutes on 28 September, 3 minutes on 16 October and 2 minutes on 19 October, and none in November. Elevated errors with no fuller scope are read as partial, as on minimax-api and minimax-voice-cloning, so minor only (20). T2A is limited to 60 requests a minute, with higher limits on audio subscriptions (15). Error codes 1002 and 2045 say to retry later and avoid sudden increases, with no Retry-After or backoff figures (10 of 15). No SLA (0). No beta or preview label on T2A (10). 20 + 20 + 15 + 10 + 0 + 10 = 75.

Murf TTS API + MCP 90

Atlassian status page at murf.statuspage.io, linked from the rate-limits doc, with history back to February 2024 (20). No incident posted since 2025-09-22, still so on 1 November 2026, so the 90-day record is clean. The page tracks only two components (API and Studio), so a clean record says less than a page with a component per region (30). Concurrency limits published per model and region, 5 on US-East and 2 elsewhere for Falcon 2.1 on free and pay as you go, and since 22 October Falcon 2.1 streaming responses report the region, limit and slots in use (15). The errors page tells you to retry 429, 500 and 503 with exponential backoff (15). No SLA found on any self-serve tier (0). Falcon 2.1 carries no beta label (10).

MiniMax Speech (T2A) 56

API reading of the checklist. Audio comes back hex-encoded inside JSON by default, with subtitles opt-in and format, bitrate and sample rate settable (15 of 25). Voices are listed by type through POST /v1/get_voice, which has no pagination and returns 300+ system voices for all (10 of 20). Errors come as numeric codes in base_resp with a short remedy for each, inside responses documented only as 200 (13 of 20). No idempotency key, and the MCP tools carry no read-only or destructive annotations (10 of 20). Two required fields. No official SDK for speech, with MCP servers in Python and JavaScript (8 of 15). Total 56.

Murf TTS API + MCP 71

Read as an API. Output in MP3, WAV, FLAC, A-law, mu-law or Base64 at 8 to 48 kHz, with word timestamps, streaming over HTTP or WebSocket, and inline Base64 instead of a download link (22 of 25). Per-request cap of 3,000 characters documented and the voice list filters by model, but there's no length control beyond splitting text yourself (12 of 20). Machine-readable error and warning codes with a trace_id (18 of 20). Backoff guidance documented (10). Nothing found on whether failed calls are billed and no seed for repeatable output (0 of 10). Three required fields including locale, and the only official SDK is Python (9 of 15).
