OpenTusk is agentic storage for AI. It gives your agents and applications a durable, encrypted storage layer backed by the Walrus decentralized network. AI agents need to persist data — conversation context, generated artifacts, shared memory, backups. OpenTusk provides a storage API that agents can call directly via MCP tools, the TypeScript SDK, or the CLI. Files upload to a fast hot cache, sync to Walrus for decentralized durability, and stay encrypted end-to-end when they need to. 1. Create vaults — Vaults organize your files. Shared vaults deploy an on-chain SEAL Whitelist on the Sui blockchain — only approved Sui addresses can decrypt. Public vaults are open and unencrypted. 2. Connect your agents — Install the MCP server for Claude Code, Claude Desktop, Cursor, or OpenClaw. Or use the TypeScript SDK or CLI directly. 3. Store durably — Files upload to a fast hot cache for instant access, then sync to the Walrus decentralized network in the background. No single point of failure.

OpenSEO is an SEO MCP server that connects Claude, Cursor, Codex, or any MCP client to real data, so your agent can research keywords, inspect live SERPs, compare competitor domains, summarize backlink context, save keyword opportunities, review rank-tracking data, and read first-party Search Console signals. MCP (Model Context Protocol) is the standard AI clients use to call external tools. An SEO MCP server exposes SEO data (keyword metrics, SERP results, domain and backlink stats) as tools an agent can call mid-conversation. Instead of guessing at search volumes or rankings, your agent queries real data from your OpenSEO project, and can save its findings back so you can review them in the UI. Pair it with keyword research for an agent-driven first pass over any topic.

The Model Context Protocol (MCP) is an open standard that allows AI agents (like Claude or ChatGPT) to securely interact with external tools and data sources. You connect your AI agent (the MCP client) directly to Ortto's MCP server. This enables your agent to understand and act upon your Ortto data. Your agent can then assist with a variety of tasks using natural language prompts. For example: - "Show me the performance of my email campaigns from the last 30 days." - "Which journeys are performing the best in terms of conversions?" - "Get me a list of my most engaged contacts from this month."

Record Python/Rust/TypeScript program runs to local SQLite; query call trees, exceptions, and value flow over MCP (refuses rather than guesses). Local-first for coding agents — not LLM-prompt tracing; not the unrelated Telegram `sensorium-mcp`.

You don't download anything. In Claude, a tool like Plainpaper is a connector, a secure link between your chat and the service. From then on, Claude can open a Plainpaper board and write campaign cards onto it whenever you ask, without you leaving the conversation. One difference from Canva or Notion, and it's worth being straight about: Plainpaper isn't in Claude's browsable connector directory yet, so you add it as a custom connector instead of finding it in a list. In practice that means pasting one URL. Everything after that, the sign-in and the approval, is the standard flow, and the connector behaves identically to a directory one once it's on.

One request, sixteen photographs, credits included — inside the conversation. Follow up with “more like 3” and the assistant knows what you mean. Nothing to install.
