lg-tv-mcp: Skill for Claude Code

Verifying lg-tv-mcp

The surface is the stdio MCP server (server/index.js). Drive it with the MCP client SDK the same way test/helpers.mjs does — never import server modules directly.

Against the real TV

Spawn the server with the default environment; it reads the paired config from ~/Library/Application Support/lg-tv-mcp/config.json (no pairing prompt if clientKey is present):

import { Client } from '<repo>/node_modules/@modelcontextprotocol/sdk/dist/esm/client/index.js';
import { StdioClientTransport } from '<repo>/node_modules/@modelcontextprotocol/sdk/dist/esm/client/stdio.js';
const client = new Client({ name: 'verify-client', version: '0.0.0' });
await client.connect(new StdioClientTransport({
  command: process.execPath, args: ['<repo>/server/index.js'], env: process.env,
}));
await client.callTool({ name: 'get_status', arguments: {} });

Gotchas:

• Call get_status first; if the TV is off, power_on + ~15s boot, and restore the original power state when done.
• The subpath imports (@modelcontextprotocol/sdk/client/index.js) only resolve from inside the repo; from a scratchpad script use the full node_modules/.../dist/esm/... paths as above.
• Tool results: JSON in content[0].text (+ structuredContent), except screenshot, which returns a base64 image block (960x540 JPEG). DRM video planes (Netflix playback) capture as black; UI renders fine.

Against the fake TV

test/fixtures/fake-tv.mjs simulates SSAP over plain ws and serves capture JPEGs over HTTP on the same port. Point the server at it with LG_TV_URL=<tv.url> and LG_TV_DATA_DIR=<tempdir with seeded config> — see withTv() in test/controls.test.js.
