How to Set Up and Use Agent Registry

AgentRegistry is a centralized, curated registry for AI agents, MCP servers, skills, and reusable prompt templates that provides a trusted discovery and deployment layer for enterprise AI ecosystems. It supports registering MCP servers from npm, PyPI, OCI/Docker, or HTTP/SSE endpoints, and ships with a CLI tool (arctl), a local web UI, a REST API, and Kubernetes/Helm support for team-scale deployments. Teams use it to maintain a governed catalog of approved agents and capabilities, auto-generate client configurations for Claude Desktop, Cursor, and VS Code, and manage the full lifecycle of their agent infrastructure.

Prerequisites

  • Docker Desktop with Docker Compose v2+ installed (required for the registry backend)
  • curl available for the installer script
  • An MCP-compatible client such as Claude Desktop or Cursor to consume registered servers
  • Internet access to reach the AgentRegistry package sources during setup
1

Install the arctl CLI

Run the official installer script which downloads the arctl binary for your platform and adds it to your PATH.

curl -fsSL https://raw.githubusercontent.com/agentregistry-dev/agentregistry/main/scripts/get-arctl | bash
2

Verify the installation

Confirm that arctl is installed and accessible by checking the version.

arctl version
3

Start the AgentRegistry daemon

Start the local registry service using Docker Compose. The registry will be available at localhost:12121 and the web UI will open in your browser.

arctl start
4

Register an MCP server

Add an MCP server to your registry from an npm package, specifying its name and source. Registered servers are catalogued with metadata and can be deployed to clients with a single command.

arctl register mcp-server \
  --name my-server \
  --source npm:my-mcp-package
5

Generate client configuration

Once servers are registered, generate a ready-to-use config file for Claude Desktop, Cursor, or VS Code. This command outputs the correct JSON structure for your chosen client.

arctl generate-config --client claude-desktop
6

Browse the registry web UI

Open the local registry web interface to explore, search, and manage registered agents, skills, and MCP servers visually.

open http://localhost:12121

Agent Registry Examples

Client configuration

Example Claude Desktop configuration pointing to a server managed by AgentRegistry.

{
  "mcpServers": {
    "agentregistry": {
      "command": "npx",
      "args": ["agentregistry"]
    }
  }
}

Prompts to try

Example prompts for working with the AgentRegistry MCP interface.

- "List all registered MCP servers in the registry"
- "Find agents that have database access capabilities"
- "Show me the skills registered for code review workflows"
- "Generate a Claude Desktop config that includes all approved MCP servers"

Troubleshooting Agent Registry

arctl start fails because Docker is not running

Open Docker Desktop and wait for it to fully start (the whale icon in the taskbar/menu bar should stop animating). Then re-run 'arctl start'. The registry requires Docker Compose v2+, so also verify with 'docker compose version'.

Web UI at localhost:12121 is not accessible

Check that the registry container is running with 'docker ps | grep agentregistry'. If the container exited, check logs with 'docker logs agentregistry'. Port 12121 must not be in use by another service; check with 'lsof -i :12121'.

Generated config does not include newly registered servers

Re-run 'arctl generate-config --client claude-desktop' after registering new servers. The command reads the current registry state each time; any previously saved config file will be stale after registry changes.
