Pick the AI app you use, then copy the settings.
Before you install
- Basic checks: 1 of 1 passed
- Runs on your computer with your user’s permissions (files, network, apps).
- You fill in yourself:
ABSOLUTE_AGENT_REGISTRY_URL,ABSOLUTE_PACKAGE_REGISTRY_URL
You need

Common questions
Is Agents 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 on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).
Is it still maintained?
The GitHub repo last changed –, and the latest version (0.2.0) reached the registry 4 months ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.
What can I use instead?

@absolutejs/agents-mcp
A production, read-only MCP server for finding cryptographically verified AI agents and production agent-first packages in the AbsoluteJS public registry. It gives MCP clients one installable discovery surface for agent names, capabilities, protocols, publishers, authentication metadata, and signed descriptors.
Run it
{"mcpServers": { "absolute-agents": { "command": "npx", "args": ["-y", "@absolutejs/agents-mcp"] } } }
No credentials are required. The server fetches the public HTTPS registry, refuses redirects, bounds response size and time, validates every record, and caches successful indexes briefly. To use a compatible federated registry, set ABSOLUTE_AGENT_REGISTRY_URL to its HTTPS index URL. The package catalog is independently configurable with ABSOLUTE_PACKAGE_REGISTRY_URL.
MCP surface
search_agentsfilters verified listings by text, capability, and MCP/A2A/ Arazzo/WebMCP/HTTP/OpenAPI/WebSocket interface type, with bounded pagination.get_agentreturns one listing by canonical discovery ID or agent URL.search_packagesfilters the production AbsoluteJS catalog by purpose, category, and supported standard.get_packagereturns one package by exact scoped npm name.registry_statusreports freshness, schema, endpoint, and verified count.absolute-agents://registry/indexexposes the validated index as a resource.absolute-agents://packages/indexexposes the validated package catalog.
All tools are marked read-only. Discovery never grants authorization: callers must follow each returned agent's advertised OAuth, approval, and delegation requirements before taking actions.
Library use
import { AgentRegistryClient, createAgentsMcpServer } from "@absolutejs/agents-mcp";const registry = new AgentRegistryClient(); const results = await registry.search({ capability: "calendar", interfaceType: "a2a" }); const { server } = createAgentsMcpServer({ client: registry });
The npm package declares mcpName: io.github.absolutejs/agents and ships the official MCP Registry server.json metadata alongside its AbsoluteJS manifest.
