What the code does

Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

  exec(args: string[]): Promise<void>;
Dumps the whole environment apps/leclap-web/vite.config.ts:58
    'process.env.NODE_ENV': JSON.stringify(process.env.NODE_ENV ?? 'development'),

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Connect this server

This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

run in your terminal
claude mcp add video -- npx -y @leclap/mcp
~/Library/Application Support/Claude/claude_desktop_config.json
{
  "mcpServers": {
    "video": {
      "args": [
        "-y",
        "@leclap/mcp"
      ],
      "command": "npx"
    }
  }
}
~/.codex/config.toml
[mcp_servers.video]
command = "npx"
args = ["-y", "@leclap/mcp"]
.cursor/mcp.json
{
  "mcpServers": {
    "video": {
      "args": [
        "-y",
        "@leclap/mcp"
      ],
      "command": "npx"
    }
  }
}

        "@leclap/mcp"
      ],
      "command": "npx"
    }
  }
}

This one needs environment variables set before it will start: LECLAP_MCP_OUTPUT_DIR (Directory rendered videos are written to. Defaults to ~/.leclap/renders.), LECLAP_MCP_MEDIA_DIR (Allowlisted directory the server may read source media from. Defaults to ~/.leclap/media.), LECLAP_MCP_RENDER_TIMEOUT_MS (Per-render timeout in milliseconds. Defaults to 600000.), LECLAP_MCP_ALLOW_REMOTION (Opt in to the Remotion clip renderer, which executes local JavaScript. Off by default.), LECLAP_MCP_REMOTION_ENTRY (Path to a Remotion entry point used by render_remotion_clip when it is enabled.). The author declared them in the registry entry; get the values from the project itself.

LeClap — questions

Answers built from our own checks of this server.

Why is there no uptime for LeClap?
LeClap runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package @leclap/mcp was installed 82 times last week.
How do I connect LeClap?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls @leclap/mcp straight from npm; nothing to host, nothing to sign up for.
How many people use LeClap?
The npm package @leclap/mcp was installed 82 times in the last week. Week over week that is +55%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is LeClap open source?
Yes — it is published under the MIT licence, written in TypeScript, 24 stars on GitHub and 1 open issue. The source link is on this page, so you can read exactly what it does with your data before you connect it.
