HIGHLong base64-encoded blob hidden in the skill documentationSS-SKILL-INJECT-B64-PAYLOAD-01 · Prompt injection · package.json

HIGH — once decoded by the agent, an encoded payload has the same impact class as plain-text injection.

Why it matters

A base64 string of 128+ characters appears in a documentation file. Encoded prompt injection hides the hostile instruction in base64 — invisible to keyword filters — and relies on the agent's ability to decode it at runtime. There is no normal authoring reason to embed a multi-hundred-byte base64 blob in skill docs.

How to fix

Remove the encoded blob, or decode it and review what it actually contains.

Decode the base64 string and confirm it is not an instruction directed at the agent.
Move any legitimate binary or signature data into a dedicated file (*.sig, SIGNATURES) outside the documentation.

<h1 align="center">tubemind-secure-mcp</h1>

YouTube intelligence, powered by Claude. Secure by design. Model Context Protocol server with 18 tools for YouTube research, analytics, benchmarking and content strategy.

📦 18 tools · 🔐 OAuth2 + AES-256-GCM · 🛡️ OWASP Top 10 · 🤖 Claude Desktop ready

🎯 Why tubemind-secure-mcp?

Turn Claude into a YouTube growth strategist — without ever handing it your raw OAuth tokens.

⚡ Plug-and-play with Claude Desktop — drop one config block, get 18 production tools.
🔐 Secure by default — tokens encrypted at rest (AES-256-GCM), SSRF guard, rate limiting, audit log, Zod-validated inputs. OWASP Top 10 mapped end-to-end.
📊 Real data, not scraping — official YouTube Data API v3 + YouTube Analytics API. Brand Accounts supported.
🧠 Beyond raw API — built-in heuristics for CTR, retention, keyword difficulty, content gaps, hook angles and N-day content calendars.
🪶 Tiny footprint — 3 runtime deps (@modelcontextprotocol/sdk, googleapis, zod). Node ≥ 20.

✨ Overview

tubemind-secure-mcp is a Model Context Protocol (MCP) server that gives Claude Desktop (and any MCP client) 18 production-grade tools for working with YouTube:

🔍 Search & SEO — trending topics, keyword stats, tag suggestions
📺 Video & Channel — list videos, read/update metadata, get tags
📊 Analytics — channel analytics (views, watch time, retention) via YouTube Analytics API
🏆 Benchmark — compare your channel against competitors
🧠 Heuristics — keyword difficulty, title patterns, content gaps, hook angles, CTR potential, retention signals, content calendar
🕵️ Competitor research — competitor video discovery

Built secure by design: OAuth2 (Brand Account ready), AES-256-GCM token encryption at rest, SSRF guard, rate limiting, audit logging, Zod input validation — mapped to OWASP Top 10.

📦 Installation

# Global install
npm install -g tubemind-secure-mcp

# Or run on demand
npx tubemind-secure-mcp

Requires Node.js ≥ 20.

🔐 OAuth Setup (one-time)

YouTube APIs need an OAuth2 token. The package ships with an auth server that walks you through it.

1) Create OAuth credentials in Google Cloud

Go to Google Cloud Console → APIs & Services → Credentials
Enable YouTube Data API v3 and YouTube Analytics API
Create OAuth 2.0 Client ID → Web application
Authorized redirect URI: http://localhost:4000/oauth/callback
Copy the Client ID and Client Secret

2) Configure environment

Copy .env.example to .env and fill in:

YOUTUBE_CLIENT_ID=your-client-id.apps.googleusercontent.com
YOUTUBE_CLIENT_SECRET=your-client-secret
YOUTUBE_REDIRECT_URI=http://localhost:4000/oauth/callback

# Generate with: openssl rand -hex 32
TOKEN_ENCRYPTION_KEY=your-64-char-hex-key

RATE_LIMIT_PER_MINUTE=60
REQUEST_TIMEOUT_MS=10000
AUDIT_LOG_PATH=./logs/audit.log
NODE_ENV=production

3) Run the OAuth flow

pnpm auth
# or: npx tsx --env-file=.env src/auth-server.ts

Open http://localhost:4000, sign in with the Google account that owns the channel (Brand Accounts supported), authorize, and the encrypted token is saved to ./tokens/youtube.token.json.

🔒 Security

tubemind-secure-mcp is built secure-by-default. See SECURITY.md for the full posture mapped to OWASP Top 10.

Control	Implementation

A03 — Injection	Zod schemas on every tool input
A04 — Insecure Design	Rate limit, request timeout, SSRF guard (host whitelist)
A05 — Misconfiguration	`.env.example` template, no defaults that leak
A07 — AuthN Failures	OAuth2 PKCE-style flow, encrypted token storage
A08 — Software/Data Integrity	Pinned deps, `pnpm audit` in CI, dependabot
A09 — Logging Failures	Audit log of every tool call (timestamp, tool, success)
A10 — SSRF	Outbound calls restricted to `googleapis.com` family
