72/100

ollos-mcp

Eyes and ears for AI agents. Local, offline transcription, keyframes, on-screen text and a pre-publish review of any audio, video or image, as an MCP server, a CLI and a Node library. No Python, no cloud, no API key.

Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

ollos_diarize

Split a recording into speaker turns — who talked from when to when — and, if you pass the jobId of a finished ollos_transcribe, label every transcript segment with its speaker. Runs locally: pyannote segmentation, WeSpeaker voice embeddings and agglomerative clustering. For a Zoom local recording f

ollos_search

Find moments across everything ollos has transcribed or read from screen: "what did we decide about the deadline", "when did the 401 error appear". Hybrid retrieval — BM25 for exact names, acronyms and numbers plus multilingual embeddings for meaning, fused by reciprocal rank — returning up to k pas

ollos_probe

Read what a file, URL or folder actually is, in under a second: kind (video/audio/image), duration, resolution, aspect ratio and which platforms it fits, codecs, fps, audio channels and track count. Use it first, before any other ollos tool, to decide what to run and to detect a Zoom recording folde

ollos_transcribe

Transcribe the speech in audio or video, locally with Whisper, with timestamps per segment and a heuristic confidence. Silence is skipped with a voice-activity detector and known Whisper hallucinations are removed, so what you get back was actually said. Pass vocabulary with domain terms ("Claude Co

ollos_keyframes

Pick the frames of a video that carry information and pack them into 3×3 contact sheets, so you can "watch" an hour of video in a handful of images. Frames are chosen by perceptual-hash change (works on screen recordings, where scene detection sees nothing), hard cuts (window switches, modals), opti

ollos_read_screen

OCR the text visible in a video or image and scan it for secrets: API keys, JWTs, bearer tokens, .env lines, private deployment URLs, local URLs, e-mails. Frames are selected as in ollos_keyframes, then read in upscaled tiles (small UI text is unreadable otherwise). Secret findings combine three sig

ollos_review

Check a video before it goes public and return a verdict (ok / warn / block) with findings: loudness vs the platform target (YouTube -14 LUFS) and true peak, silence gaps worth cutting, aspect ratio vs the platform (a 1890×1080 file gets black bars on YouTube), and secrets visible on screen. The sec

ollos_job

Get the state of a job started by ollos_transcribe, ollos_keyframes, ollos_read_screen, ollos_review or ollos_diarize: stage, percentage, and — once completed — the formatted result plus resource links, so no second call is needed. Poll every few seconds; the server keeps jobs on disk, so a jobId su

ollos_cancel

Stop a queued or running ollos job by jobId — for example when the user changes their mind about a long transcription, or asked for the wrong file. The running stage is aborted (ffmpeg and model inference stop within a second) and the job is marked cancelled; partial artifacts already written stay o

ollos_frames

Return contact sheets or individual frames from a finished ollos_keyframes or ollos_read_screen job as images you can look at. Ask for sheets first (each shows 9 timestamped frames); ask for a single frame only when you need a close-up. Default 6 images per call (maxImages, up to 12) to protect the

All four hints declared on every tool

10/10 tools missing one or more hints — ollos_diarize (missing: destructiveHint, idempotentHint); ollos_search (missing: destructiveHint, idempotentHint, openWorldHint); ollos_probe (missing: destructiveHint, idempotentHint), +7 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.

For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.

Tool test coverage

Only 0/10 tools referenced in tests (0%)

Write tests that reference each tool by name so every tool has at least one test.

// full audit trail
The findings above are the summary. The full trail, every check we ran, each deduction, the network hosts observed and the dependency advisories, goes to verified publishers, along with an alert whenever a new one lands. Verified publishers can also review each finding and dispute it in one click. Publisher corrections have sharpened several of our checks this month, because the maintainer knows the codebase better than any scanner.
// improvement guidance — verified publishers only
We have 3 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
