# Arkon Vault — AI Connector Arkon Vault publishes 13 MCP tools to Claude. Marketplace availability, tool surface, verification tier, and what Node8 measured against the live endpoint. Source: https://node8.ai/ai-connectors/productivity/arkon-vault/ --- [AI Connectors](https://node8.ai/ai-connectors/) · [Productivity](https://node8.ai/ai-connectors/productivity/) # Arkon Vault Carry project state and handoffs between different AI assistants Listed in Claude · 13 published tools · Community-listed [Claude connector docs](https://vault.arkoncybersecurity.com/support) [vault.arkoncybersecurity.com](https://vault.arkoncybersecurity.com/) Overview ## What Arkon Vault does Arkon Vault addresses a problem created by using several assistants: each starts without knowing what the others established. It holds project state deliberately, so work can resume anywhere. Claude can preflight a task, find the authoritative project and next action, accept or create a structured handoff, publish a checkpoint, preserve a decision, and search shared context. The boundary is stated clearly: the connector stores only what a user sends through its tools, and does not ingest the surrounding conversation or read local files. An optional Windows companion, Arkon Sync, is separate and opt-in. Community tier. ### Who it is for People and teams working across more than one AI assistant on the same project. ### Tool surface The endpoint asks for credentials before naming anything, so thirteen is the publisher's figure. Preflight checks, handoff creation and acceptance, checkpoint publishing, decision records and context search are the groupings described. Availability ## Where Arkon Vault is listed Arkon Vault is listed in the Claude connectors directory only. Zachary Hammons has no app under the same domain in the ChatGPT directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them. The MCP server behind a Claude connector is usually the same server a ChatGPT app would need, so the absence is a distribution decision rather than a technical one. Claude listing ## In the Claude connectors directory Arkon Vault publishes 13 tools to Claude. That is a mid-sized surface: 54.3% of the 1,253 Claude-listed connectors expose fewer. The median Claude-listed connector filed under Productivity publishes 12, so this one runs one tool above its bucket's median and ranks 224th of 462 by tool count. It falls in the 11-20 tools band, which holds 22.5% of the Claude directory. Arkon Vault publishes a remote MCP endpoint. Claude connects to it over HTTP; there is nothing to install locally. Every connector in the Claude directory is remote, all 1,253 of them, so transport is not a differentiator there. Publisher Zachary Hammons Verification Community-listed (61.5% of the Claude directory) Filed under Productivity Endpoint `https://vault.arkoncybersecurity.com/mcp` Documentation [Publisher setup docs](https://vault.arkoncybersecurity.com/support) Published tools 13 · 11-20 tools band Depth rank in Productivity 224 of 462 Snapshot August 2026 Arkon Vault is community-listed in the Claude directory, the tier 770 of 1,253 connectors sit in (61.5%). It is the default for a self-published server, and says nothing either way about quality. In the publisher's words ## How Zachary Hammons describes it > Arkon Vault is a private AI work-continuity layer for people and teams using more than one AI. Claude can preflight work, find the authoritative project and next action, accept or create structured handoffs, publish checkpoints, preserve decisions, search shared context, and save project state. The MCP connector stores continuity content a user deliberately sends through Vault tools; it does not automatically ingest the surrounding Claude conversation or read local files. Optional Arkon Sync is separate, opt-in Windows software. It sends limited session-derived project records from supported local AI sessions—including title, a brief summary derived from session metadata or the first user message, AI platform, last-active time, message count, working directory, deep link, and session ID—to Arkon Vault's servers, where they are stored in the user's tenant-isolated private vault. It does not upload complete raw transcripts or full assistant responses. Users can view records in the Vault dashboard, download a tenant-scoped JSON export from Account → Your data, or submit or cancel a verified deletion request there. Details: https://vault.arkoncybersecurity.com/data-deletion. The MCP vault\_sync tool only refreshes the server-side continuity index and any configured Notion mirror; it cannot start Arkon Sync or upload AI conversations.
