Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
QC videos, podcasts, and clips before upload — timestamped flags with agent-ready repair prompts.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.
Pick the AI app you use, then copy the settings.

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Your agent can generate video. It can't tell you the audio cut out at 0:08, a frame froze at the stitch seam, or the captions are cropped. UploadCheck can — and hands back the exact timestamps to fix.
For anyone whose agent, pipeline, or editor produces media that ships to real people — AI-video pipelines, Shorts/Reels, podcasts, client deliverables.
An agent that writes code can run the tests. An agent that renders a video has no idea whether it's broken.
So the broken export ships: silence where narration should be, a frozen frame where two clips were stitched, lips out of sync, captions clipped by the platform UI, loudness well off target. Somebody notices in the comments.
UploadCheck is the check your agent calls before it publishes. Point it at the finished file. It returns PASS, WATCH, or BLOCK with per-flag timestamps and machine-actionable fixes — so the agent repairs only the flagged span and re-checks, instead of guessing or shipping.

Get a free key at [uploadcheck.app](https://uploadcheck.app) — 40+ gates, 200 checked minutes/month, no card. Machine-readable install snippets for every client live in mcp-install.json.
Keep your key private. It's a secret bearer token tied to your plan minutes. Put it in your personal MCP config — never in a committed file, a shared prompt, or a report.
Once installed, just ask:
check ./final-cut.mp4 before I upload
The agent calls qc_run_local_file, polls qc_get_job, then reads qc_get_report and shows you the flags with timestamps.
40+ automated gates run on every check, including:
| Picture | frozen/looped frames, black frames, canvas fit & pillarboxing, temporal warping, flicker, interlace combing |
| Audio | dead air, clipping, loudness (LUFS) & true peak, loudness range, channel balance, mains hum, dropouts |
| Sync & text | lip/audio drift, caption safe-area, text contrast, cropped or overlapping text |
| Delivery | resolution/codec/frame-rate spec, Shorts/Reels format |
Paid plans add AI "oracle" gates — garbled speech, duplicated faces in AI crowds, narration match.
*What it doesn't do: it doesn't tell you whether a clip was AI-generated. It assumes it might be, and checks whether it's clean enough to publish.*
| Tool | What it does |
|---|---|
qc_estimate_cost | Estimate checked minutes and effective gates before running |
qc_run_local_file | Check a local export (reads the file, sends it to the hosted API) |
qc_run_video | Check a YouTube URL, signed URL, upload id, or base64 payload |
qc_get_job | Poll status, progress, verdict, metered minutes |
qc_get_report | The finished report: verdict + timestamped flags + evidence |
qc_get_events | Lifecycle events, so the agent can explain what ran |
qc_get_artifacts | List generated report artifacts |
qc_get_marker_csv | Editor marker CSV (drop flags straight into your NLE timeline) |
qc_create_upload_url | Signed upload URL for larger files |
Pass idempotency_key to qc_run_video when an agent might retry the same asset — the API returns the existing job instead of duplicating the run.
Use profile when you know the media type but don't want to hand-pick gates: auto, shorts, audio, thumbnail, generic_creator_video, and named delivery targets like youtube_shorts, podcast_delivery, broadcast_r128, ai_render_gate. Explicit checks always win.

This package is a thin MCP client over the hosted UploadCheck API — checks run server-side, not on your machine. Small and medium local files can be sent inline (base64) without durable storage; use signed upload URLs for large ones.
