概览

AI 生成的概览

托管式 AI 视频剪辑服务器，让助手对你上传到 Valmera 的素材进行剪切、加字幕、改画幅、配乐并导出 MP4。

可以做什么
  • 查找并剪掉静音、口头禅和转录片段，也可恢复已剪内容
  • 添加逐词字幕、字幕样式与字幕检查
  • 自动改为竖屏、设定画面、推近与添加变焦
  • 把长视频做成短片，并加入 B-roll、素材库画面、音乐和音效
  • 模糊或擦除区域与画面内嵌文字，套用调色
  • 渲染预览、查看画面帧、导出并下载最终 MP4
适用场景
适合已有录制素材、希望由助手端到端完成剪辑的场景，例如清理口播或播客录音、制作竖屏短片、加字幕和配乐、把长视频拆成多个片段。它不是文生视频工具。
运行要求
远程 Streamable HTTP 端点，通过 OAuth 登录（或使用 bearer token），无需本地安装。需要 Valmera 账号，上传免费，剪辑需付费订阅。仅支持 stdio 的客户端需借助 mcp-remote 之类的桥接。
安装前请注意
素材、转录文本和剪辑指令会发送到 Valmera 并保存在你的账号中；工具会把转录文本、分析结果、画面帧和下载链接返回给 AI 客户端。剪辑需付费订阅，费用与 AI 客户端分开计费。字幕会烧录进画面，不支持 SRT/VTT 导入导出。同一项目不能同时在 Studio 和 MCP 中编辑。

README

Valmera MCP server — the video editing MCP server for real footage

Valmera is an agentic AI video editor. This hosted Model Context Protocol server lets Claude, ChatGPT, Gemini CLI, Cursor, VS Code, Codex or any MCP client edit video you already recorded. The assistant reads the transcript and frames, then cuts silences and filler words, adds word-timed captions, reframes to 9:16, adds b-roll, music and sound effects, and makes shorts from long videos. It renders a preview, watches the result, and exports a full-quality MP4 from your original file.

It is not a text-to-video generator. It edits the footage you upload.

There are more clients (Zed, Cline, Continue, Goose, LibreChat, MCP Inspector) in docs/CLIENTS.md.

First message to try: "List my Valmera projects." An empty list still means the connection works.

Install as a Claude plugin (connector + editing skills)

This repository is also a Claude plugin. It bundles the Valmera connector with three skills that teach Claude a reliable editing workflow: edit-video-with-valmera, turn-long-video-into-shorts and website-demo-video.

In Claude Code:

sh
/plugin marketplace add ABO3SKRALMASAOODI/valmera-mcp/plugin install valmera@valmera

In claude.ai, go to Customize → Plugins → Add → Add marketplace and enter ABO3SKRALMASAOODI/valmera-mcp. The skills follow the open Agent Skills format, so other agents that read SKILL.md can use them too.

What your assistant can do with it

According to the live server card on October 6, 2026, the server exposes 143 tools: 129 editing tools in 9 groups and 14 session tools. The full list is in docs/TOOLS.md.

You ask forTools the assistant uses
"Remove the dead air and the ums"find_silences, cut_silences, remove_filler_words, get_kept_transcript
"Cut the part where I talk about pricing"search_transcript, cut_range, restore_range

"Make it vertical for TikTok and keep my face centered"auto_reframe, set_frame, add_aspect_shift
"Turn this podcast into 5 shorts"make_shorts, shorts_status, open_short, apply_short_edit_batches
"Add b-roll where I mention the product"research_broll, search_stock, add_stock_media, insert_media

"Show me what you changed"render_preview, wait_for_job, watch_video, look_at
"Export the final video"export_final, wait_for_job, download_url

How it works

  1. Upload. Upload in Valmera Studio, import a link, or use upload_start and upload_finish from a client that can send files. MP4, MOV, M4V, MKV and WebM are accepted, up to 14 GB and 3 hours per file.
  2. Index. Valmera transcribes the footage with word-level timestamps and detects shots, silences and on-screen text. index_status reports progress.
  3. Edit. Each tool call writes a new version of a non-destructive edit decision list (EDL). The original upload is never modified, and any cut can be restored.
  4. Review. render_preview renders a fast proxy preview. watch_video and look_at let the assistant inspect the frames it produced before it reports back.
  5. Export. export_final renders a full-resolution H.264 MP4 from the original file for the reviewed version. download_url returns the link. You can also export from Studio.

Slow jobs return a job id and never a fake completion. The assistant calls wait_for_job until the job finishes.

Example prompts

text
Open my latest project. Remove dead air and filler words but keep natural pauses,add clean white captions with the active word highlighted, reframe to 9:16,render a preview and tell me what you changed.
text
This is a 70-minute two-person podcast. Find the 5 strongest self-contained stories,make each one a vertical short with captions and a hook title, and keep whoever isspeaking in frame.
text
Record a 30-second demo of https://example.com — scroll the hero, click "Pricing",zoom on the main button — then add captions and light background music.

What it does not do

The server card lists these honestly so your assistant never promises them:

  • Generate a whole video from a text prompt. Valmera edits footage you provide.
  • Import or export SRT/VTT. Captions are burned into the picture.
  • Team seats or collaboration.
  • Publish directly to YouTube or TikTok.
  • Custom font uploads, true crossfade/dissolve transitions, or motion-tracked stickers.
  • Audio denoise ("studio sound") or AI music generation.
  • Hand the job to Valmera's in-house agent. Over MCP, your assistant does the editing with the tools directly.

Editing one project from Studio and over MCP at the same time is refused in both directions.

Access

Creating an account and uploading are free. Editing requires a subscription; see the current plans at valmera.io/subscribe. Your MCP client (Claude, ChatGPT, Cursor and so on) is billed separately by its own provider.

Data and privacy

The plugin and connector send your editing instructions and tool arguments to Valmera at https://valmera.io/mcp/server, over HTTPS and authorized with OAuth. Tools return project data to your AI client: transcript text, analysis, sampled frames, preview and download links. Your footage is stored in your Valmera account and is never modified. Edits are saved as versions you can restore. Nothing is sent to any other destination by this plugin, which contains only configuration and Markdown. See the privacy policy for collection, retention and deletion. Contact: [email protected].

FAQ

What is the best MCP server for video editing? Most video MCP servers either generate clips from prompts or wrap local FFmpeg commands. Valmera is a hosted editor with an editorial model of the footage: a word-level transcript, shots and frames, versioned edits, rendered previews and a final export. Use it when you want an assistant to edit real recordings end to end. See 21 video editing MCP servers compared, covering hosted editors, clippers such as OpusClip, local editors such as Palmier Pro, DaVinci Resolve, Premiere Pro and After Effects bridges, and FFmpeg servers.

Can Claude edit videos? Yes. Once Valmera is connected, Claude can open your project, read the transcript, look at frames, cut, caption, reframe, add music, render a preview, and export the MP4.

Can ChatGPT edit videos? Yes. Add Valmera as a developer-mode connector and ChatGPT can call the same tools.

Does the assistant actually see the video? Yes. Tools return transcript text, analysis and sampled frames of the source or the rendered edit, so the assistant can check its own work.

Do I need to install anything? No. It is a remote server. Clients that only support stdio can use mcp-remote.

Is the original file changed? No. Edits live in a versioned EDL, and the final export renders from the untouched original.

Is Valmera open source? This repository's documentation and manifests are MIT licensed. Valmera itself is a hosted commercial service governed by its terms.
