Le Clap MCP Server

An MCP server that exposes the ffmpeg-video-composer engine as agent-callable video tools. Its 6 documented tools cluster into read & search, validate, compose, probe. It runs locally over stdio via the published package.

People connecting media tools to Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

01 · Install Le Clap

before you install - you'll need

Set LECLAP_MCP_OUTPUT_DIR, LECLAP_MCP_MEDIA_DIR before connecting.

Claude Code

claude mcp add heristop-leclap-packages-leclap-mcp -- npx -y @leclap/mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "heristop-leclap-packages-leclap-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "@leclap/mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

license MIT - declared in the repository

npm package @leclap/mcp - the @leclap scope differs from the repo owner (heristop); confirm it's the project's official package

registry vendor namespace dev.leclap - domain-verified with the official MCP registry

03 · What Le Clap can do

Prose above is summarized from the project's README and registry record - no invented capabilities.

Capability map

Tools grouped from the project's README - what Le Clap lets an agent do.

read & search

1 tool - e.g. The JSON Schema for a template descriptor + a short authoring guide

get_template_schema

Validate

1 tool - e.g. Dry-run an inline descriptor (no render) → { valid, sectionCount, orientation, requiredClips, formFields }

validate_template

Compose

1 tool - e.g. Validate an inline descriptor and render → { outputPath, durationSeconds, sizeBytes, videoCodec, audioCodec, renderId }, plus a resource_link to the mp4

compose_video

Probe

1 tool - e.g. Inspect a local media file → codecs, duration, sample rate, size

probe_media

Render

1 tool - e.g. _(bonus, opt-in)_ Render a composition from your own Remotion project → an mp4 clip for a project_video section

render_remotion_clip

Ping

1 tool - e.g. Liveness check

ping
