lunara
Registry code: c84f1cd2946e4652
Lunara produces subtitles: one upload (or URL) yields a written-language track plus a translated track, with ASR text and timings preserved exactly. Start with lunara_start_subtitle_job for a URL or lunara_upload_video for a local file, then poll lunara_get_job every 15–30 s until status is "completed", then call lunara_get_srt. Free tools: lunara_get_job, lunara_get_srt, lunara_list_cues, lunara_readability, lunara_get_coverage, lunara_qa_contract, lunara_probe_media, lunara_get_glossary.

- Is lunara live?
- Yes — it answered the hub's last check (checked 2h ago). It answered 100% of checks over the last 30 days.
- Is lunara free to use?
- Not anonymously — it asks for a key or a login before it will serve. Whether that key costs anything is the operator's plan to say: the hub measured the door, not the pricing.
- What tools does lunara have?
- 18 tools: lunara_get_glossary, lunara_glossary_extract, lunara_list_tools, lunara_finish_upload, lunara_get_job, lunara_get_srt, lunara_list_cues, lunara_start_subtitle_job, ….
- Is lunara safe to connect?
- The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.
lunara_get_glossary auth-required 2h ago
Return the proper nouns Lunara has learned for this org, so names are spelled consistently across tracks.
{ "type": "object", "properties": { "limit": { "type": "integer", "maximum": 500, "minimum": 1, "description": "Default 100." } }, "additionalProperties": false }arguments 12 lineslunara_glossary_extract auth-required never probed
Find candidate proper nouns in a job’s cues, ranked by frequency, with the first cue they appear in. Suggestions for a glossary, not corrections — nothing is rewritten.
{ "type": "object", "required": [ "jobId" ], "properties": { "jobId": { "type": "string", "description": "The job whose cues to scan." }, "limit": { "type": "integer", "maximum": 200, "minimum": 1, "description": "Maximum terms to return. Default 50." } }, "additionalProperties": false }arguments 19 lineslunara_list_tools auth-required 2h ago
Return every subtitle tool Lunara exposes, with the minutes each one costs. Call this first when you are unsure which tool fits.
{ "type": "object", "properties": {}, "additionalProperties": false }arguments 5 lineslunara_finish_upload auth-required never probed
Tell Lunara the bytes are uploaded so the pipeline can start. Returns the job id to poll with lunara_get_job.
{ "type": "object", "required": [ "videoId", "uploadId", "key", "durationMs", "parts" ], "properties": { "key": { "type": "string", "description": "The object key." }, "parts": { "type": "array", "items": { "type": "object", "required": [ "PartNumber", "ETag" ], "properties": { "ETag": { "type": "string" }, "PartNumber": { "type": "integer", "minimum": 1 } }, "additionalProperties": false }, "description": "Uploaded parts, each { PartNumber, ETag }." }, "videoId": { "type": "string", "description": "The video id from lunara_upload_video." }, "uploadId": { "type": "string", "description": "The multipart upload id." }, "durationMs": { "type": "integer", "minimum": 1, "description": "Media duration in milliseconds." } }, "additionalProperties": false }arguments 51 lineslunara_get_job auth-required never probed
Return the state of a subtitle job: status, progress, whether the SRT is ready, and how many cues it has. Poll this after lunara_upload_video.
{ "type": "object", "required": [ "jobId" ], "properties": { "jobId": { "type": "string", "description": "The job id returned by lunara_upload_video." } }, "additionalProperties": false }arguments 13 lineslunara_get_srt auth-required never probed
Return the subtitle file for a finished job. One line per cue. Use track="secondary" for the translated track (English by default).
{ "type": "object", "required": [ "jobId" ], "properties": { "jobId": { "type": "string", "description": "The job id." }, "track": { "enum": [ "primary", "secondary" ], "type": "string", "description": "primary = the written-language track; secondary = the translation." } }, "additionalProperties": false }arguments 21 lineslunara_list_cues auth-required never probed
Return subtitle cues for a job as timestamps plus text, so you can inspect or reference individual lines before proposing edits.
{ "type": "object", "required": [ "jobId" ], "properties": { "jobId": { "type": "string", "description": "The job id." }, "limit": { "type": "integer", "maximum": 500, "minimum": 1, "description": "How many cues to return. Default 100." }, "offset": { "type": "integer", "minimum": 0, "description": "Skip this many cues. Default 0." } }, "additionalProperties": false }arguments 24 lineslunara_start_subtitle_job auth-required never probed
Run the full eight-layer subtitle pipeline on an audio or video URL you can already host. Produces a written-language track and a translated track. Prefer lunara_upload_video when the file is local.
{ "type": "object", "required": [ "audioUrl" ], "properties": { "audioUrl": { "type": "string", "description": "A URL Lunara can download (public or pre-signed)." }, "spokenLang": { "type": "string", "description": "What the speaker is speaking, e.g. yue-Hant-HK. Defaults to primaryLang." }, "primaryLang": { "enum": [ "zh-Hant", "yue-Hant", "zh-CN", "en", "ja", "ko" ], "type": "string", "description": "Language of the written track. Default yue-Hant." }, "secondaryLang": { "enum": [ "zh-Hant", "yue-Hant", "zh-CN", "en", "ja", "ko" ], "type": "string", "description": "Language of the translated track. Default en." } }, "additionalProperties": false }arguments 41 lineslunara_get_coverage auth-required 2h ago
Report how much of the source timeline the subtitles cover, and list suspicious gaps longer than a second. Use before shipping a long video.
{ "type": "object", "required": [ "jobId" ], "properties": { "jobId": { "type": "string", "description": "The job to inspect." } }, "additionalProperties": false }arguments 13 lineslunara_subtitle_from_url auth-required never probed
Start a persisted subtitle job from a URL you already host — no upload needed. Returns a job id; poll lunara_get_job every 15–30 s until status is "completed", then call lunara_get_srt. Prefer this over lunara_upload_video whenever the media is reachable by URL.
{ "type": "object", "required": [ "audioUrl" ], "properties": { "audioUrl": { "type": "string", "description": "Direct HTTP(S) URL to the audio or video file. Must be downloadable by our server." }, "filename": { "type": "string", "description": "Display name for the result. Defaults to the URL basename." }, "spokenLang": { "type": "string", "description": "What the speaker is speaking, e.g. yue-Hant-HK. Defaults to auto-detect." }, "primaryLang": { "enum": [ "zh-Hant", "yue-Hant", "zh-CN", "en", "ja", "ko" ], "type": "string", "description": "Language of the written track. Default yue-Hant." }, "secondaryLang": { "enum": [ "zh-Hant", "yue-Hant", "zh-CN", "en", "ja", "ko" ], "type": "string", "description": "Language of the translated track. Default en." } }, "additionalProperties": false }arguments 45 lineslunara_upload_video auth-required never probed
Reserve an upload slot and return the object key plus a signed URL per part. After uploading the bytes call lunara_finish_upload. Use this for a file you hold locally.
{ "type": "object", "required": [ "filename", "mime", "sizeBytes" ], "properties": { "mime": { "type": "string", "description": "MIME type, e.g. audio/mpeg, video/mp4." }, "filename": { "type": "string", "description": "Original filename, used for the download name." }, "projectId": { "type": "string", "description": "Project to upload into. Omit to let Lunara reuse the most recent project for this organisation." }, "sizeBytes": { "type": "integer", "minimum": 1, "description": "Exact file size in bytes." }, "primaryLang": { "enum": [ "zh-Hant", "yue-Hant", "zh-CN", "en", "ja", "ko" ], "type": "string", "description": "Written-track language. Default yue-Hant." }, "secondaryLang": { "enum": [ "zh-Hant", "yue-Hant", "zh-CN", "en", "ja", "ko" ], "type": "string", "description": "Translated-track language. Default en." }, "clientOperationId": { "type": "string", "description": "Idempotency key. Reuse the same value to retry without creating a second upload." } }, "additionalProperties": false }arguments 56 lineslunara_transcribe auth-required never probed
Run speech recognition only — no rewrite, no translation. Returns timed segments. Use this when you want the transcript itself, or when you plan to pick a later stage yourself.
{ "type": "object", "required": [ "audioUrl" ], "properties": { "audioUrl": { "type": "string", "description": "Direct HTTP(S) URL to the audio or video file." }, "spokenLang": { "type": "string", "description": "What the speaker is speaking, e.g. yue-Hant-HK. Defaults to auto-detect." } }, "additionalProperties": false }arguments 17 lineslunara_translate auth-required never probed
Translate the text of an existing job’s cues into another language. Every cue boundary and timestamp is preserved; only the text changes. Use this instead of translating yourself so the timing contract holds.
{ "type": "object", "required": [ "jobId", "targetLang" ], "properties": { "jobId": { "type": "string", "description": "The job whose cues to translate." }, "track": { "enum": [ "primary", "secondary" ], "type": "string", "description": "Which track to read. Default primary." }, "targetLang": { "enum": [ "zh-Hant", "en", "ja", "ko" ], "type": "string", "description": "Target language." } }, "additionalProperties": false }arguments 32 lineslunara_rewrite auth-required never probed
Turn spoken Cantonese cue text into written Chinese. Every cue boundary and timestamp is preserved. Deliberate mispronunciations are never corrected, and proper nouns are protected.
{ "type": "object", "required": [ "jobId" ], "properties": { "jobId": { "type": "string", "description": "The job whose cues to rewrite." }, "track": { "enum": [ "primary", "secondary" ], "type": "string", "description": "Which track to read. Default primary." } }, "additionalProperties": false }arguments 21 lineslunara_segment auth-required never probed
Approximate split, not audio-grounded segmentation: cue text is divided at clause punctuation and each piece receives a share of the original span proportional to its character count. The words are not changed. Timings are estimated, so treat them as a reading aid rather than a re-alignment — use lunara_start_subtitle_job if you need timing derived from the audio.
{ "type": "object", "required": [ "jobId" ], "properties": { "jobId": { "type": "string", "description": "The job whose cues to re-cut." }, "track": { "enum": [ "primary", "secondary" ], "type": "string", "description": "Which track to read. Default primary." }, "maxCueMs": { "type": "integer", "maximum": 15000, "minimum": 500, "description": "Duration ceiling per cue in ms. Default 7000." } }, "additionalProperties": false }arguments 27 lineslunara_qa_contract auth-required never probed
Run the contract gate over both tracks: ASR text and timings byte-exact, cue length bounds, no empty cues. Returns pass/fail per rule. Free, because refusing a broken track should never cost the caller money.
{ "type": "object", "required": [ "jobId" ], "properties": { "jobId": { "type": "string", "description": "The job to validate." }, "track": { "enum": [ "primary", "secondary", "both" ], "type": "string", "description": "Which track to check. Default both." } }, "additionalProperties": false }arguments 22 lineslunara_probe_media auth-required never probed
Return duration, dimensions, codecs and container for a URL, plus whether the audio is mono 16 kHz already. Call this before choosing an ASR engine.
{ "type": "object", "required": [ "mediaUrl" ], "properties": { "mediaUrl": { "type": "string", "description": "URL to probe." } }, "additionalProperties": false }arguments 13 lineslunara_readability auth-required never probed
Per-cue reading speed, displayed length and characters-per-second, with the cues that exceed comfortable limits. Mirrors the metrics shown in the editor.
{ "type": "object", "required": [ "jobId" ], "properties": { "jobId": { "type": "string", "description": "The job to measure." }, "track": { "enum": [ "primary", "secondary" ], "type": "string", "description": "Default primary." } }, "additionalProperties": false }arguments 21 lines
This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.
Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.
- Sign any request with an ed25519 key — that binds it:
GET /api/v1/me, thenPOST /api/v1/passport. - Prove it is yours. Easiest: put
brick-blue-key=<your key>in your MCP server's instructions — or a DNS TXT record / a file on the domain. - Ask the hub to check:
POST /api/v1/passport/claim-endpointwith this listing's idc84f1cd2946e4652.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.
An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
