What is video-editing?

A video-editing connection for creating projects and editing timelines from local files or media URLs. It supports adding text, captions, and music, then checking and exporting the result.

Use it to cut and assemble clips, add captions or text, add music, validate edits, and export finished videos.

It lets a coding agent make precise video changes while keeping track of the latest timeline version and each editing operation.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00055	$0.01069
Opus 5.5	$0.00022	$0.00428
Sonnet 5.5	$0.00011	$0.00214

Security

Grade A, and why

video-editing scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 89 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Editing video through mcpCut

Works the same against a self-hosted server (http://127.0.0.1:8100/mcp) or the hosted service at https://mcpcut.com/mcp (bearer token, browser editor on top — the user sees your edits live at mcpcut.com/projects).

You are connected to a real video editor. It keeps projects: immutable timeline snapshots with a journaled history. Every tool call that edits returns the full updated project snapshot — always work from the latest returned snapshot, never from memory of an earlier one.

Conventions that make your edits reliable

Errors come back as data, not exceptions: a failed call returns {"error": "<reason>"}. Read it, fix the cause, retry deliberately — never retry the identical call in a loop.
Element ids, media ids, track ids are in every snapshot. Use ids from the latest snapshot; ids never survive a delete.
Times are seconds (floats). Positions like pos accept presets ("center", "top", "bottom"...).
One gesture = one tool call. The journal (editor_get_history) records each named operation; prefer several precise calls over one clever one.
Long operations (export, captions, analysis) run synchronously and can take minutes on big media — call them once and wait.

The core workflow

Create: editor_create_project (optionally with metadata tags).
Ingest: editor_add_media(project_id, source) — source is a local path or an http(s) URL (URL import downloads server-side). The returned media entry carries duration/resolution once probed.
Assemble: editor_add_clip(project_id, media_id, start_time, duration, trim_start) places footage on the timeline; editor_trim_clip, editor_split_clip, editor_move_clip, editor_resize_clip refine it. Extra layers: editor_add_video_track / editor_add_audio_track.
Dress: editor_add_text(project_id, content, start, duration, pos, size) for titles; editor_add_overlay for images/GIFs/video overlays; editor_add_music(project_id, source) for a music bed; editor_set_transform (+ editor_set_keyframes for motion), editor_set_color, editor_add_transition.
Captions (if the ASR extra is installed): editor_auto_captions (project_id) transcribes the timeline audio and lays word-timed captions. editor_update_texts fixes any wording afterwards.
Check before rendering: editor_validate(project_id) reports structural problems; editor_render_preview(project_id, at_time) returns a frame so you can see the composition at a timestamp.
Export: editor_export(project_id) renders the final file and returns a download path/URL. Exports are swept after a retention window (24 h by default) — tell the user to save the file, or re-export.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
