Overview

AI-generated overview

A read-only MCP server for discovering cryptographically verified AI agents and production agent-first packages in the AbsoluteJS public registry.

What you can do
Search verified agent listings by text, capability and interface type (MCP, A2A, Arazzo, WebMCP, HTTP, OpenAPI, WebSocket), with bounded pagination and lookup by canonical discovery ID or agent URL. Search the production AbsoluteJS package catalog by purpose, category and supported standard, and fetch a package by its exact scoped npm name. Check registry freshness, schema, endpoint and verified count, and read the validated agent and package indexes as resources.
When to use it
Useful when you want an assistant to find agents or packages to integrate with, compare their capabilities, protocols, publishers and authentication metadata, or check that a registry listing is current before relying on it.
Requirements
Runs locally via npx from the npm package @absolutejs/agents-mcp (Node.js). No credentials are required. Network access to the public HTTPS registry is needed; the optional ABSOLUTE_AGENT_REGISTRY_URL and ABSOLUTE_PACKAGE_REGISTRY_URL variables point at compatible federated registries.
Before you install
Discovery is read-only and never grants authorization: before acting on a returned agent, its advertised OAuth, approval and delegation requirements must be followed. Pointing the optional registry URL variables at a third-party registry means trusting that source's listings. Desktop-only; no web executable.

Installation

In SourceWeft

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

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

README

@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

json
{  "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_agents filters verified listings by text, capability, and MCP/A2A/ Arazzo/WebMCP/HTTP/OpenAPI/WebSocket interface type, with bounded pagination.
  • get_agent returns one listing by canonical discovery ID or agent URL.
  • search_packages filters the production AbsoluteJS catalog by purpose, category, and supported standard.
  • get_package returns one package by exact scoped npm name.
  • registry_status reports freshness, schema, endpoint, and verified count.
  • absolute-agents://registry/index exposes the validated index as a resource.
  • absolute-agents://packages/index exposes 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

ts
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.

Score

50% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.

  • Tools listed15 pts

    Answer tools/list without a credential, or ship a package that starts in a sandbox without one.
