Subtitle Toolkit is an MCP server with 8 tools an agent can call, among them check_subtitle_timing, clean_subtitles, convert_subtitle. It answers at https://subtitle-mcp.toolboxes.top/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 4 of 4 times since 23 September 2026; the last check, on 7 November 2026, succeeded.
Convert, clean, retime and validate SRT, WebVTT, ASS/SSA, SBV and TTML subtitles. 8 tools.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
check_subtitle_timing | Audit subtitle readability and produce a report: reading speed (CPS), cue durations that are too short or too long, lines that are too wide, more than two lines, and overlapping cues. Returns a formatted report listing every flagged cue. Inputs: content, max_cps, min_duration_seconds, max_duration_seconds, max_line_length |
clean_subtitles | Strip noise from auto-generated subtitles: HTML/WebVTT tags, ASS override codes, music and sound-effect cues, speaker labels, empty cues and duplicate lines. Returns the subtitle file in SRT or WebVTT. Inputs: content, remove_tags, remove_sound_cues, remove_speaker_labels, drop_empty, drop_duplicates |
convert_subtitle | Convert subtitle text between formats. Reads SRT, WebVTT, ASS/SSA, YouTube SBV and TTML/DFXP; writes SRT, WebVTT, ASS, CSV or plain text. Format is auto-detected unless `from` is given. Inputs: content, to, from, dedupe |
fix_subtitle_encoding | Repair mojibake — text where UTF-8 bytes were decoded as a single-byte encoding (cp1252/Latin-1 or cp1251). Symptoms: "é", "’", "привет". Returns the repaired text and how many passes were applied. Inputs: content, read_as, twice |
merge_subtitles | Append one subtitle track after another (CD1 + CD2, or a second language track). The second track is offset so it starts after the last cue of the first, plus an optional gap. Inputs: content, append_content, gap_seconds, to |
retime_subtitles | Fix subtitle timing. Use offset_seconds for a uniform shift (whole track early/late). Use ratio, or from_fps/to_fps, for progressive drift caused by a frame-rate mismatch. Pass exactly one of the three. Inputs: content, offset_seconds, ratio, from_fps, to_fps |
split_subtitles | Split one subtitle track into two parts at a given timecode, keeping original timecodes. Use the `at` argument plus `part` to fetch either half. Inputs: content, at, part, to |
text_to_subtitles | Turn a plain transcript (one line per caption) into an SRT file with evenly spaced timecodes. Timing is a starting point, not a real transcription — say so when you present the result. Inputs: content, duration_seconds, start_seconds, max_chars_per_cue |

It answered our last check on 7 November 2026 in 137 ms. Over 4 checks since 23 September 2026 it answered 4. Status here comes from Neuronto's own probes, not from the publisher.
Yes. It is published by toolboxes.top and served from subtitle-mcp.toolboxes.top, the vendor's own domain: https://subtitle-mcp.toolboxes.top/mcp.

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://subtitle-mcp.toolboxes.top/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
Publisher: top.toolboxes. Endpoint host: subtitle-mcp.toolboxes.top. ARD identifier: urn:air:top.toolboxes:mcp:subtitle-toolkit.
First indexed 22 September 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
