### Description (declared)

# YouTube MCP Server

A single-process [MCP](https://modelcontextprotocol.io) server that exposes public YouTube data —
transcripts, search, video metadata and statistics, comments, channels, categories — as tools an LLM
can call. It speaks **stdio**: any local agent (Claude Desktop, an editor plugin, a script) launches
`youtube-mcp` as a subprocess and gets the tools over stdin/stdout. **No network exposure, no auth,
no account** — just a YouTube Data API key.

One Python process: FastMCP server, YouTube Data API client, transcript fetching and cache all live
in the same application. No sidecar, no second service, no Redis.

- **15 tools**, all namespaced `youtube_*`, read-only public data.
- **stdio by default.** HTTP is available for a shared/deployed instance — see
  [Optional: HTTP mode / container](#optional-http-mode--container).
- **API-key only.** No OAuth, no uploads, no channel management.
- **Dislike counts do not exist.** YouTube made them private in December 2021; no endpoint returns
  them, and this server will not estimate them.

## Quick start

```bash
git clone <this repo> && cd youtube-mcp
uv sync                       # creates .venv from uv.lock
export YOUTUBE_API_KEY=...    # required — the server fails fast without it
uv run youtube-mcp            # speaks MCP on stdin/stdout
```

Point an MCP client at the published package — `uvx` fetches it from PyPI, so no local
checkout is needed:

```json
{
  "mcpServers": {
    "youtube": {
      "command": "uvx",
      "args": ["--from", "dreadster3-youtube-mcp", "youtube-mcp"],
      "env": { "YOUTUBE_API_KEY": "your-key-here" }
    }
  }
}
```

The console script dispatches on `MCP_TRANSPORT`, which defaults to `stdio`:

```bash
uv run youtube-mcp                          # stdio (default)
MCP_TRANSPORT=http uv run youtube-mcp       # streamable HTTP on 0.0.0.0:8088
```

The cache is a local SQLite file (`DATABASE_PATH`, default `cache.db` in the working directory).
It is **ephemeral by design*…
