Features
v1.4 exposes 17 MCP tools:
| Tool | What it does |
|---|---|
analyze_video | Full audio + visual analysis with custom prompts. Uses Gemini multimodal understanding. |
get_transcript | Extract timestamped transcript with speaker identification. Supports 100+ languages via auto-detection. |
ask_about_video | Ask any question about the video content. |
find_video_moments | Find matching moments with compact/standard/full structured output. |
analyze_video_segment | Analyze only a selected time range. |
prepare_video_context | Analyze once and save a reusable local context for follow-up questions and evidence lookup. |
ask_video_context | Answer from saved context by default; Gemini reanalysis is explicit opt-in. |
list_video_contexts | List saved local contexts. |
delete_video_context | Delete one saved context. |
get_video_frame | Extract a local still frame, using the YouTube fast path when possible. |
get_video_clip | Extract a short local clip, with a 30s cap and YouTube fast path when possible. |
get_video_evidence_asset | Select saved evidence and return a frame or clip reference. |
list_video_sources | Inspect local source/context/asset cache metadata. |
cleanup_video_cache | Dry-run or clean managed cache files; dry-run is the default. |
watch_and_analyze | Extract tutorial steps, shell commands, code snippets, and file paths from technical videos. |
execute_tutorial_steps | Validate and review extracted steps safely; executes only with confirmation. |
check_analysis_job | Poll background job status for TikTok/Instagram async downloads. |
Supported Platforms
| Platform | Method | Speed |
|---|---|---|
| YouTube | Direct Gemini analysis — no download needed for analysis. Frame/clip extraction uses yt-dlp -g stream URLs + ffmpeg when available, with a small section-download fallback. | Instant / fast local extraction |
| TikTok | tikwm.com API (fast) → yt-dlp fallback with a safe MP4 H.264/H.265 selector that avoids unsupported ByteDance bvc2/bytevc2 streams when possible | ~8s |
| Page scrape via curl_cffi (fast) → yt-dlp fallback | ~10s |
YouTube videos are analyzed directly through Gemini's native video understanding — zero download, zero upload, maximum speed. For YouTube evidence assets,
source.mp4is not always required: saved contexts keep the original URL, so frame/clip tools can use the local stream fast path later.
Architecture
| Component | Role |
|---|---|
| Gemini 2.5 Flash | Latest multimodal model — full audio + visual understanding in a single pass |
| FastMCP 3.x | MCP protocol framework over stdio transport |
| yt-dlp + curl_cffi | Video download with Chrome browser impersonation to bypass anti-bot. TikTok downloads prefer locally decodable MP4 H.264/H.265 formats and reject ByteDance bvc2/bytevc2 streams. |
| tikwm.com API | TikTok fast-path fallback when yt-dlp is WAF-blocked |
| ffmpeg | Local frame/clip extraction, including YouTube stream URL extraction without full-video downloads |
| Background Jobs | Async threading for TikTok/Instagram to prevent Claude Desktop timeouts. Failed inner results are reported as failed jobs, not completed jobs. |
Operating Modes
These are behavior modes, not tool names:
| Mode | Behavior |
|---|---|
auto | Default adaptive behavior: YouTube direct analysis; TikTok/Instagram fast API/scrape then yt-dlp fallback; saved contexts reused when available. |
api | Gemini-backed analysis or reanalysis. This is used by analysis tools and explicit Gemini opt-ins. |
client | MCP client workflow mode: long TikTok/Instagram analysis returns a background job_id for polling. |
local | Saved-context, cache, frame, and clip operations that avoid Gemini unless explicitly requested. |
Quick Start
The packaged runtime lives at src/video_url_analyzer_mcp/server.py; the
console entry point is video_url_analyzer_mcp:main. Pick whichever
install path matches your workflow.
Option A — uvx (no install)
uvx video-url-analyzer-mcp
Works on Windows / macOS / Linux as long as uv is on PATH.
Option B — Windows wizard (recommended for new users)
git clone https://github.com/u2n4/video-url-analyzer-mcp.git
cd video-url-analyzer-mcp
powershell -ExecutionPolicy Bypass -File scripts\install_windows.ps1
The wizard:
- Verifies Python 3.10+ and (optionally)
uv. - Installs the package as an editable checkout or via
uv tool install. - Lets you save
GEMINI_API_KEYto a User environment variable or to a gitignored.env.keys.local. Keys are masked in logs (AIza...abcd), never printed in full. - Lets you pick a default model via
VIDEO_ANALYZER_MODEL. - Runs an offline import smoke test.
- Hands off to
scripts/configure_mcp_clients.ps1for client setup.
Option C — Manual install (any OS)
git clone https://github.com/u2n4/video-url-analyzer-mcp.git
cd video-url-analyzer-mcp
pip install -e .
python -m video_url_analyzer_mcp
Get a free key at Google AI Studio,
then set it once in your shell environment (setx GEMINI_API_KEY ... on
Windows, or your ~/.zshrc / ~/.bashrc on macOS/Linux). For local dev
only, you can also drop it in a gitignored .env.keys.local next to the
repo.
Windows launcher
start.bat loads .env.keys.local (if present), sets safe defaults
(VIDEO_ANALYZER_MODE=auto), and runs python -m video_url_analyzer_mcp.
Use it as a command value in any MCP client that prefers a single
executable.
Integration
Run scripts/configure_mcp_clients.ps1 for an interactive menu, or copy
the snippets below from docs/mcp-config-examples.md. The wizard backs up
existing client config, validates JSON/TOML, and never overwrites unrelated
MCP servers.
Claude Desktop (%APPDATA%\Claude\claude_desktop_config.json)
{
"mcpServers": {
"video-url-analyzer": {
"command": "uvx",
"args": ["video-url-analyzer-mcp"]
}
}
}
The wizard prefers leaving the API key in your OS environment. If you must
embed it, add "env": { "GEMINI_API_KEY": "YOUR_KEY_HERE" }.
Claude Code (CLI)
claude mcp add video-url-analyzer --transport stdio -- uvx video-url-analyzer-mcp
Or, after pip install -e . in the repo:
claude mcp add video-url-analyzer --transport stdio -- python -m video_url_analyzer_mcp
Codex CLI (~/.codex/config.toml)
[mcp_servers.video-url-analyzer]
command = "uvx"
args = ["video-url-analyzer-mcp"]
VS Code / GitHub Copilot MCP
Workspace registration writes .vscode/mcp.json:
{
"servers": {
"video-url-analyzer": {
"command": "uvx",
"args": ["video-url-analyzer-mcp"]
}
}
}
For all clients, restart the application after editing config so the new
MCP server is picked up. Full snippets — including Cursor, Windsurf, and
Antigravity — live in docs/mcp-config-examples.md.

Security
This server has been hardened against a comprehensive threat model audit:
| Layer | Protection |
|---|---|
| SSRF | URL allowlist — only YouTube, TikTok, Instagram domains accepted. Private IPs, localhost, file:// blocked. |
| Command Injection | shell=False + shlex.split(). Dangerous command blocklist (rm -rf, reverse shells, eval, pipe-to-shell). |
| Path Traversal | 25+ sensitive path patterns blocked (.ssh, .aws, .env, system dirs, AppData). |
| TLS | Full certificate validation on all downloads. |
| Browser Cookies | Opt-in only via VIDEO_ANALYZER_COOKIES=true. Disabled by default. |
| Download Size | Hard limit of 100 MB per video. |
| DoS Protection | Max 10 concurrent background jobs. Auto-expiry after 1 hour. Storage cap of 200 analyses. |
| Schema Validation | Gemini JSON responses validated before execution. Response size capped at 500K chars. |
| Dependencies | All versions pinned in requirements.txt. |
Environment Variables
| Variable | Description | Default |
|---|---|---|
GEMINI_API_KEY | Google Gemini API key | Required |
ANALYSES_DIR | Directory for saved analyses | ./analyses |
VIDEO_CONTEXT_DIR | Directory for saved reusable video contexts | video_contexts |
VIDEO_SOURCE_DIR | Directory for cached downloaded source media | video_sources |
VIDEO_ASSET_DIR | Directory for extracted frames/clips | video_assets |
VIDEO_ANALYZER_COOKIES | Enable browser cookie access (true/false) | false |
VIDEO_DOWNLOAD_TIMEOUT | Override download and yt-dlp timeout values, in seconds | Existing per-operation defaults |
VIDEO_FFMPEG_TIMEOUT | Override ffmpeg extraction timeout values, in seconds | Existing per-operation defaults |
VIDEO_GEMINI_TIMEOUT | Optional Gemini HTTP timeout, in seconds | SDK default |
VIDEO_ANALYZER_MODEL | Single-knob default model id used for both fast and deep model resolution. Per-call model= and GEMINI_FAST_MODEL / GEMINI_DEEP_MODEL still take precedence. | unset |
GEMINI_FAST_MODEL | Override for compact/standard detail mode | gemini-3.1-flash-lite-preview |
GEMINI_DEEP_MODEL | Override for full detail mode | gemini-3.1-pro-preview |
Default fast model:
gemini-3.1-flash-lite-preview. Default deep model (used whendetail="full"):gemini-3.1-pro-preview. SetVIDEO_ANALYZER_MODELto override both at once. Model availability can vary by Google account, region, and API tier — fall back togemini-flash-latestif the 3.1 preview ids are not yet enabled for your key. |VIDEO_ANALYZER_MODE| Behavior preset (auto/api/client/local); read bystart.bat|auto|
Troubleshooting
| Issue | Solution |
|---|---|
GEMINI_API_KEY not set | Create .env file or pass via environment variable |
| TikTok download fails | tikwm.com fallback activates automatically. Ensure curl_cffi is installed. |
TikTok bvc2 / bytevc2 codec | v1.4 avoids these unsupported ByteDance streams when a compatible MP4 H.264/H.265 format exists. If no compatible stream is available, tools return a structured unsupported_codec or no_compatible_format error instead of uploading or pretending success. |
| Instagram download fails | pip install curl_cffi for browser impersonation support |
ENOENT on Windows | Use start.bat as command in Claude Desktop config |
| Impersonate target not available | Reinstall: pip install "yt-dlp[curl-cffi]" |
| Claude Desktop timeout | TikTok/Instagram run in background — use check_analysis_job(job_id) to poll |
| Background job says failed | Expected when the worker result is an error, Gemini file processing fails, or media validation rejects the source. check_analysis_job no longer reports these inner failures as completed. |
prepare_video_context repeats work | It reuses cached contexts unless force_refresh=true |
YouTube source.mp4 missing | Expected in some cases. Frame/clip tools can recover from the saved URL and use yt-dlp -g + ffmpeg fast extraction. |
| Transient Gemini 503/5xx | Gemini generate_content calls retry up to 3 times with exponential backoff. 4xx auth/schema/user errors are not retried. |
