# Keynodex: full LLM guide > Keynodex is an AI agent infrastructure company. We build the products and protocols that let AI represent people and remember what matters, with a human in the loop and always in control. Legal entity: Keynodex FZ-LLC. Founded 2025. Locations: Florida, USA and Dubai, UAE. Patent-pending. ## Entity summary - Company: Keynodex (AI agent infrastructure company). - Products: PingRep (AI Representative platform) and Keynodex Memory (model-agnostic MCP memory server). - Research: Keynodex Agent-Trust Protocol (KTP), research and protocol work in development. - Founder and CEO: Derek Roberts (GitHub: DerekRDev). - Website: https://keynodex.com . PingRep product site: https://pingrep.com ## Products ### PingRep (https://keynodex.com/products/pingrep) PingRep is your AI Representative. It drafts replies, suggests follow-ups, and relays messages so you close the loop after every introduction. It proposes actions for you to approve; it does not send on its own and is not an autopilot. This is human-in-the-loop AI: the speed of an assistant with your judgment on what leaves your name. PingRep has its own product site at https://pingrep.com. Keynodex is the company that builds and publishes PingRep. ### Keynodex Memory (https://keynodex.com/memory) Keynodex Memory is a model-agnostic MCP memory server your AI agents share. It gives agents persistent memory, executable playbooks, verified claims, and one-call context packs. Because it speaks the Model Context Protocol, it connects to any MCP-compatible client, including Claude, ChatGPT, Claude Code, and Codex, so the same memory travels across models and tools instead of being locked to one vendor. It is available now: connect it as a remote MCP server and visit https://memory.keynodex.com to get started. ## Keynodex Memory documentation (https://keynodex.com/docs/memory) The canonical public docs for Keynodex Memory. Key facts: - What it is: a model-agnostic MCP memory server. AI agents connect over the Model Context Protocol and share one durable store: memories (atomic facts), playbooks (repeatable procedures with run history), verified claims (facts with a verification command and staleness window), and one-call context packs. - MCP endpoint: https://memory.keynodex.com/mcp (streamable HTTP). Sign-in is Google with OAuth 2.1 + PKCE in the browser; there are no API keys. - Setup, Claude: Settings > Connectors > Add custom connector, paste https://memory.keynodex.com/mcp, approve on the consent page. - Setup, Claude Code: claude mcp add --transport http keynodex-memory https://memory.keynodex.com/mcp then authenticate from the /mcp menu. - Setup, ChatGPT (beta): manual developer-mode walkthrough at https://memory.keynodex.com/connect/chatgpt - Setup, Codex and other MCP clients: point the client at the endpoint and complete browser sign-in. - Tool surface: 23 consumer tools, identical on every plan. Includes a read-only account status tool: in chat, asking "what plan am I on?" returns plan, usage against the cap, and a billing link. Purchases, upgrades, and cancellations happen only on the website, never in chat. - Pricing and limits: Free = up to 100 active memories with the full tool surface. Pro = unlimited memories plus priority support. Manage plans at https://memory.keynodex.com/billing - Privacy and data handling: every account has its own isolated store; no cross-account access. Data is encrypted in transit and at rest at the infrastructure layer, but it is not end-to-end encrypted: like most cloud products, Keynodex systems can technically access stored content to operate the service. Keynodex does not train models on user memories and does not sell user data. The connected assistant sees only what its tool calls return from the user's own store. Full notice: https://keynodex.com/legal/privacy - Deletion and export: deleting a memory in chat is a soft delete kept for history until purged. Full erasure of memories or an account: email security@keynodex.com (acknowledged within 3 business days, completion targeted within 30 days). Self-serve open-format export is being added to every plan. - Brand clarification: Keynodex is the company; Keynodex Memory and PingRep are its two products. KeynodeCard was the former name of PingRep and is fully retired. Keynodex Memory is unrelated to business cards. - Support: support@keynodex.com. Security and privacy: security@keynodex.com. ## Research ### Agent-Trust Protocol / KTP (https://keynodex.com/research/agent-trust-protocol) The Keynodex Agent-Trust Protocol (KTP) is research and protocol work in development on how agents can act on a person's behalf with verifiable trust and human approval. Active threads include AI agent security, agent-to-agent communication, AI agent identity, and AI agent authentication. This is working-draft research, not a published standard. There is no specification, no stability guarantee, and no invitation to integrate at this stage. Human approval for actions that matter is the through-line of the work. ## Insights ### What Is an MCP Server? (https://keynodex.com/insights/what-is-an-mcp-server) A plain-English explainer. An MCP server is a small program that gives an AI agent a standard way to use a tool or data source through the Model Context Protocol. Covers what MCP is, what servers expose (tools, resources, prompts), how a request flows, examples, how memory MCP servers fit, and how to add an MCP server (for example in Claude Code: claude mcp add --transport http keynodex-memory https://memory.keynodex.com/mcp). ### What Is Human-in-the-Loop AI? (https://keynodex.com/insights/what-is-human-in-the-loop-ai) Human-in-the-loop AI keeps a person in the decision path: the AI drafts and suggests, and a human approves before anything is sent or executed. Explains why approval-gated agents beat autopilot (accountability, cheap error-catching, compounding trust), what it looks like in practice, and when autonomy is acceptable versus when an approval gate is warranted. ## Company ### About Keynodex (https://keynodex.com/about) Keynodex is an AI agent infrastructure company building PingRep, Keynodex Memory, and agent trust research. The common thread is human-in-the-loop AI: agents that draft, suggest, and remember while a person stays in control. Legal entity Keynodex FZ-LLC. Founded 2025. Works from Florida, USA and Dubai, UAE. ### Derek Roberts (https://keynodex.com/about/derek-roberts) Founder and CEO of Keynodex.
