js-sandbox MCP Server

TikTapDown MCP gives Claude, Cursor, Windsurf and any MCP-compatible assistant the power to work with TikTok content directly inside the AI conversation. Four tools, zero setup, no API keys: - **download_tiktok_video** — Returns no-watermark + watermark MP4 links for any TikTok URL. - **get_tiktok_hashtags** — 15 curated hashtag collections (fitness, beauty, food, travel, tech, education, finance, fashion, lifestyle, gaming, motivation, business, pets, music, comedy) with strategy tips per niche. - **get_best_time_to_post** — Best TikTok posting windows for 12 countries (US, GB, AU, CA, TR, DE, FR, BR, MX, JP, SA, AE) with reasoning per market. - **generate_tiktok_hook** — 8 hook categories (curiosity, contrarian, listicle, how-to, story, question, stat-drop, pattern-interrupt) × 3 formulas with concrete examples.

Rinkta is a professional-services workspace for agencies and independent teams — tasks, projects, clients, and billable entries in one place. This connector lets your AI assistant search and read your workspace, look up tasks, projects, clients, and entries, and create new tasks and clients on your behalf. Access follows your workspace role: financial data (clients, projects, entries) is only visible to owners, admins, and accountants, and read-only connections never get write access.

Template Vault is an AI-native website builder. Connect it once and your AI can generate a complete one-page website from a business brief in under a minute — real running URL, real Vercel deployment, custom domain on Pro+ tier. Six tools: `discover_business_needs` (interview the user before generating), `list_personalities`, `generate_site`, `get_generation_status`, `list_user_sites`, `publish_site`. Quotas tied to the user's Template Vault plan, so MCP calls don't bypass billing. The discovery-first workflow is the unusual bit — most MCP servers expose CRUD tools; ours expose a guided pipeline that makes the AI a better website-builder than a one-shot prompt would. Auth: OAuth 2.1 with PKCE. Works in claude.ai's "Add custom connector" flow with no manual client registration — paste the URL, click Allow, done.

### Deterministic Music Theory for Claude, Cursor, and Autonomous AI Agents Large Language Models (LLMs) frequently hallucinate music theory, leading to incorrect notes, false Roman numerals, and broken voice leading. **THIRI** solves this by providing a deterministic, mathematical music-theory engine (pitch-class-set theory over ℤ/12) directly to your AI. It gives AI assistants precise, reproducible harmonic reasoning in milliseconds, allowing them to write correct musical scores, analyze progressions, and generate playable arrangements. #### 🎷 Key Features: * **Chord Analysis (`analyze_chord`):** Parse any symbol (e.g., `Cmaj7/E`, `G7#11`) to retrieve root, quality, intervals, Roman numerals, and diatonic or chromatic harmonic functions. * **Note Resolution (`resolve_chord`):** Resolve chord symbols to spelled notes (enharmonically correct), frequencies (Hz), MIDI numbers, and scale recommendations. * **Voicing Engine (`generate_voicing`):** Generate instrument-ready voicings (rootless, shell, triad, pad, drop-2, drop-3) and calculate voice-leading scores for transitions. * **Reharmonization (`reharmonize`):** Substitute progressions using classic jazz techniques, including Tritone Substitution, ii-V Insertion, Modal Interchange, Coltrane Changes, and Backdoor cadences. *Ideal for developers building AI music assistants, digital audio workstation (DAW) agents, educational theory tools, and automated composition workflows.*

Ephemeral REST chatrooms where AI agents of different owners coordinate on a shared task. A room is one URL — no SDK, no registration. The owner creates a room, hands the URL to agents, and watches the conversation live in a browser. Remote MCP server at https://roomcomm.ru/mcp (create_room, read_messages, send_message, get_context, verify_integrity). Optional LLM arbiter tracks negotiation threads, flags contradictions, and chains every revision into a tamper-evident Ed25519-signed ledger.

Taiwan statutory payroll calculation — labor & health insurance, labor pension, 2nd-gen NHI supplementary premium, income-tax withholding, and labor-insurance old-age benefits. Sourced from official gazettes, verified against official sample data. TS (npm) + Python (PyPI) + MCP (remote & stdio).

Threat intelligence MCP server for SOC analysts, DFIR and security researchers. Scan and enrich IOCs directly from Claude, Cursor or any MCP client: IP addresses (IPv4/IPv6), domains, file hashes and blockchain addresses. Search CVEs by keyword, vendor or product, retrieve full CVE records, and explore a threat actor database (APTs, groups, TTPs) with reverse CVE-to-actor lookup. Includes scan history, bookmarks and quota management. Free tier available — no credit card required. Built by mlab.sh, the IOC & file intelligence platform.

ParseBounce is an email deliverability platform that tracks bounces, complaints and deliveries from AWS SES, SendGrid, Mailgun, SparkPost, Postmark and Mandrill. This MCP server connects Claude and other MCP clients to your ParseBounce projects: check whether an address is suppressed, investigate bounces and complaints, pull delivery/bounce/complaint rates, and look up crowdsourced email & domain reputation before you send. Search messages by recipient domain, campaign tracking ID, or full event timeline, and compare deliverability across time periods. You can also drive sending through the provider connected to your project — transactional emails and campaigns (create/pause/resume/cancel). Requires a ParseBounce account.

Turn any URL plus a schema into validated, typed JSON via the Extracto API. No CSS selectors; missing fields return null instead of guesses.
