We’ve already unpacked the generation side of AI short dramas in the previous two posts (LibTV Production Pipeline, Open-Source Alternatives), but there’s one more hurdle after the clips are produced: editing. Storyboard assets, voiceover, subtitles, BGM, and transitions — the traditional approach means dragging things around in CapCut/JianYing for hours manually.
In 2026, this pipeline can be handed off to agents too. This post covers five MCP routes that are already working end-to-end, with full configuration code — both Hermes and Claude Code are compatible.
First, the Panorama: How to Choose Among Five Routes
| Route | Mechanism | Stars / Status | Best For |
|---|---|---|---|
| cutcli | CLI generates JianYing draft files | ★195 / v1.3.9 active | Script-based batch production |
| jianying-mcp | MCP wrapper around pyJianYingDraft | ★293 | Fine-grained track/keyframe control |
| capcut-mcp | Dual HTTP API + MCP protocol | ★96 | Cursor / Claude HTTP integration |
| OpenChatCut | Open-source ChatCut, agent-native editor | ★1949 / frequent updates | Visual + agent dual-mode workflows |
| Premiere Pro MCP | CEP bridge exposing 283 tools | ★593 / MIT | PR users, professional post-production |
The shared principle boils down to one sentence: none of these tools render video — they generate project files that JianYing/PR can open, or directly manipulate an already-open project. Rendering and final export are still handled by the host software; the AI is responsible for “assembling the blocks.”
Route 1: cutcli — Script-Generated JianYing Drafts, Cleanest Approach
cutcli (cookbook at xuliang2024/cutcli-cookbook) is a CapCut/JianYing draft CLI: a single command creates a draft, adds assets, and applies subtitles — the generated draft appears directly in JianYing Desktop’s draft list, fully WYSIWYG and ready for manual tweaking.

Its agent-friendliness is the highest of the five. The cookbook’s prompts/claude/ directory provides Claude Code system prompts out of the box. The core idea is to have the model play two roles:
- Storyboard artist first: output a markdown table with shot number, timecode, visuals, subtitles, music, and transitions
- cutcli engineer next: translate that table into
run.sh— times in integer microseconds, complex JSON split intodata/*.json, comments before everyaddcommand, and chain the flow withDRAFT_ID=$(cutcli draft create ... | jq -r '.draftId')
No need to guess asset names — query commands are there to fall back on:
| |
The cookbook also includes 30+ JSON templates (vlog, product promo, subtitle cards) and v1.3.9 cloud rendering capability, under the MIT license.
Route 2: jianying-mcp — Use It When You Need Keyframe and Effect Granularity
hey-jian-wei/jianying-mcp (Apache-2.0, Python 3.13+) wraps pyJianYingDraft as a standard MCP server with extremely fine-grained tools: add_video_keyframe (keyframe animation), add_video_mask (masks), add_text_bubble (subtitle bubbles), find_effects_by_type (enumerate available effects) …
Installation and Claude integration (uv method, verbatim from the official README):
| |
MCP client configuration (Claude Code’s ~/.claude.json or Hermes config, see below):
| |
It even ships a built-in rules tool — “video production guidelines” — that makes the agent read the spec before touching anything. That’s a smart way to bake editing expertise directly into the MCP layer.
Route 3: capcut-mcp — HTTP Interface, Works with Both Chinese JianYing and International CapCut
fancyboi999/capcut-mcp takes the HTTP route: a local service (default port 9000) exposing /create_draft, /add_video, /add_subtitle, /add_effect, /save_draft and similar endpoints, while also mounting an MCP endpoint. It supports draft formats for both the Chinese JianYing and the international CapCut.
Claude-side configuration is minimal:
| |
The HTTP protocol means it’s not limited to MCP clients — curl scripts, n8n workflows, and your own Python pipelines can call it directly. Great for embedding it as a “editing backend” inside an automation system.
Route 4: OpenChatCut — If You Want an “AI Version of JianYing” Itself
0xsline/OpenChatCut (★1949, actively developed) is a different species entirely: a full open-source video editor (React 19 + Remotion 4 + Electron 43, multi-track timeline), and at the same time agent-native — Codex, Claude Code, and its built-in agent can all read, edit, and export projects, with full editability preserved.
Connecting to Claude Code takes just one command to install the skill:
| |
Then tell the agent Set up OpenChatCut. It exposes a Streamable HTTP MCP endpoint (http://localhost:5199/api/external-mcp/mcp), and the root .mcp.json already contains the local connection config.
The design aspect most worth learning is the edit session mechanism:
begin_edit_sessionreturns aneditSessionId- All subsequent reads and writes carry this id; changes land only on an isolated draft
review_edit_sessionsubmits for review- In manual mode, a human previews, approves, or rejects in the editor; in auto mode, changes take effect immediately
AI mistakes never contaminate the original project — rollback granularity is “one proposal.” That’s a critical guardrail for production environments. Custom skills go in ~/.openchatcut/skills/<slug>/SKILL.md, structured identically to the Claude/Codex skill directories.
Route 5: Premiere Pro MCP — Pro Post-Production for PR Users
hetpatel-11/Adobe_Premiere_Pro_MCP (MIT, npm package) bridges local Premiere through a CEP panel, exposing 283 tools (behind search_tools and invoke_tool entry points) plus 13 resources and 10 guided prompts. Timeline editing, color grading, and audio are all covered.
| |
Claude Code has an official plugin path:
| |
Same story for Codex (codex plugin marketplace add .). Verify the connection with one command: ask Claude to run verify_premiere_connection. Note that all three (PR, MCP client, and this package) must run on the same machine — the UXP bridge is still experimental; use CEP for production.
How to Wire This Up in Hermes
Hermes Agent has native MCP server support. Configuration goes under the mcp_servers key in ~/.hermes/config.yaml, supporting both transport types. Using jianying-mcp (stdio) and capcut-mcp (HTTP) as examples:
| |
After editing, restart Hermes. Tools register into every platform toolset under the mcp_jianying_* and mcp_capcut_* prefixes. Then you can say something like “edit the storyboards under /videos into a 60-second vertical cut per the shot list, with white-background black-text subtitle bubbles” and it becomes an executable instruction.
On the Claude Code side, write the equivalent into .mcp.json (JSON format identical to the examples above). Project-level config goes in the repo root; global config goes in ~/.claude.json.
My Recommended Combo
Building on last time’s drama production line, the minimum-hand-work division of labor is:
- Asset layer: Toonflow / LocalMiniDrama generates characters, scenes, and storyboard clips (previous post)
- Structure layer: Claude Code + cutcli — auto-generates storyboard tables from scripts, translates them into run.sh, and batch-drops drafts
- Refinement layer: Open the draft in JianYing; the human does only three things: picks the best takes, checks voiceover timing, and fine-tunes transition feel
- Export layer: cutcli v1.3.9 cloud rendering or JianYing export
Offload all the mechanical “dragging tracks” labor to agents; human time goes toward aesthetic decisions. Based on the row-and-column count of a storyboard table, a 20-shot vertical short that would take roughly 2 hours of manual editing gets compressed to 10 minutes of review plus a bit of hand-tweaking.
Two practical reminders: use absolute paths for drafts — JianYing’s resolution of relative paths often disagrees with the agent’s working directory — and add_video_segment’s duration unit is microseconds. Claude occasionally writes milliseconds instead. After the first successful run, have it self-check the unit conversion.
Sources & Verification
Installation commands, configuration snippets, and session-mechanism descriptions for all five routes are sourced from each project’s official README and docs (pulled via the GitHub API, verified 2026-09-21). Star counts: cutcli-cookbook ★195, jianying-mcp ★293, capcut-mcp ★96, OpenChatCut ★1949, Premiere Pro MCP ★593. The Hermes mcp_servers config format comes from the Hermes Agent official documentation.
