# LeClap

LeClap gives an agent tools to inspect a video template, validate it, and render an MP4 on your machine. Use it when you need repeatable output from JSON rather than model-generated footage.

## What it does

The server exposes tools for working with video templates. An agent can browse sample templates, check the schema and motion catalog, validate JSON, then render a video. Other tools inspect local media, transcribe speech, or derive visual style and structure from a reference.

Rendering runs locally through FFmpeg and produces deterministic output. A packaged sample catalog is available at runtime without the app or private creative-kit. Extracting a brand kit from a website requires `--allow-network`; without that flag, this tool cannot fetch the site.

## Requirements
- Needs: Node.js (commands run via npx)
- Environment variables: `LECLAP_MCP_OUTPUT_DIR`, `LECLAP_MCP_MEDIA_DIR`, `LECLAP_MCP_RENDER_TIMEOUT_MS`, `LECLAP_MCP_ALLOW_REMOTION`, `LECLAP_MCP_REMOTION_ENTRY` — keys and tokens: ask the human for the values, never commit them or put them in shared files.

## Install

## When to use it
- render an MP4 from a JSON template
- validate a template before rendering
- derive pacing and transitions from a reference clip
- transcribe speech in a local video

## Example prompts
- Create an MP4 from this JSON template and save it to the requested folder.
- Validate this template and report any warnings before rendering.
- Analyze the pacing and transitions in this clip, then apply them as template rules.
