Overview

AI-generated overview

ZenVault gives an assistant durable, paid infrastructure: scheduled wake-ups, webhook inboxes, TTL key-value memory, watches, human approvals and signed proofs.

What you can do
Schedule one-shot wake-ups, recurring cron webhooks, dead-man switches with check-ins, delayed payload delivery and drip delivery of item batches to a webhook. Receive and collect inbound webhooks through inboxes, front doors and forms, and forward payloads with retry until acknowledged. Keep state across runs in TTL key-value vaults, crash checkpoints, pull-based queues with leases, atomic counters and idempotency claims. Ask a human to approve or deny an action, check the verdict, and notify people over Telegram, Discord, Slack, email and other services. Watch URLs or endpoints for changes, keywords, regex, drift, DNS, ports, certificates, RSS and heartbeats, and run escalation chains. Not
When to use it
Use it when an assistant needs to act beyond a single run: delayed or recurring callbacks, buffered inbound webhooks, resumable state, human sign-off before risky actions, or monitoring that fires a webhook on change.
Requirements
A remote streamable HTTP endpoint; no local runtime, packages, environment variables or headers are declared. The manifest declares no authentication, though several tools refer to management tokens and one-time read URLs. Network access to the endpoint and to any webhook targets is needed.
Before you install
Paid per call, and extending a resource requires paying again, so usage can spend money. Tools write, send and publish data: webhooks are POSTed to targets, messages go to humans, HTML pages are published publicly and share links are created. Payloads and URLs are handed to a third-party service. Some tools return management tokens and one-time read URLs; treat them as secrets.

Installation

In SourceWeft

  1. Open ZenVault in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/eu.zenvault%2Fzenvault/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.
