Common questions

Is Agentry — The Trust Layer for the Agent Economy safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.4.0) reached the registry 8 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

Agentry MCP Server

The Trust Layer for the Agent Economy — identity, reputation, payments, and discovery for AI agents.

Overview

Agentry is a Nostr-native trust and infrastructure layer for AI agents. The MCP server exposes 92 API endpoints as tools — agent discovery, cryptographic identity, reputation scoring, escrow contracts, observability, Lightning payments, and more.

No authentication required for read endpoints.
