Frequently asked questions

What is Vizier?

Owner-signed permissions for AI agent actions; ALLOW/BLOCK/REVIEW with request-bound receipts.

How do I install Vizier?

It runs as a remote server. In Claude Code: claude mcp add --transport http vizier 'https://vizier.agendamcp.dpdns.org/mcp' --header 'Authorization: <Bearer <integration credential>. Optional: an anonymous call returns an evaluation-only decision that never grants ALLOW, and enforcement requires the server delegation policy, including a signed principal grant in required mode.>'. For other clients, paste the JSON configuration from this page into their MCP settings.

Does Vizier need an API key?

Yes. It expects Authorization, which you set in its configuration.

Who maintains Vizier?

It is published by vassiliylakhonin. AI.tn lists it but does not maintain or endorse it.

From the official MCP Registry. Listing is not an endorsement: review a server's code and permissions before giving it access to your data.
