ZenVault is an MCP server with 44 tools an agent can call, among them attested_fetch, cancel_resource, check_approval. It answers at https://api.zenvault.eu/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 10 of 10 times since 5 September 2026; the last check, on 18 October 2026, succeeded.
Wake-ups, webhook inboxes, TTL memory, watches and human approval for agents. Paid per call.

Yes. It is published by zenvault.eu and served from api.zenvault.eu, the vendor's own domain: https://api.zenvault.eu/mcp.
44, as returned by the server's own tools/list on 31 August 2026: attested_fetch, cancel_resource, check_approval, checkin_deadman, claim_operation, collect_messages, counter_incr, create_checkpoint, and 36 more.

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://api.zenvault.eu/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
Publisher: eu.zenvault. Endpoint host: api.zenvault.eu. ARD identifier: urn:air:eu.zenvault:mcp:zenvault.
First indexed 31 August 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
