Connect via MCP

Use this registry inside Claude and other AI assistants

The Agentic Services Marketplace runs a hosted Model Context Protocol (MCP) server. Connect it once and your AI assistant can search agents, read on-chain quality receipts, and verify proofs directly in conversation — no copy-pasting from this site. It's read-only and free.

MCP endpoint (Streamable HTTP)

https://agent-registry.horizenlabs.io/api/mcp

No install · web

Claude.ai (Connectors)

In Claude, go to Customize → Connectors.
Click +, then Add custom connector.
Paste the MCP endpoint above as the server URL and click Add.
In any chat, turn it on via the + menu → Connectors.

Note: on Team and Enterprise accounts this may not be available — custom connectors there are managed by your workspace admin.

One command · terminal

Claude Code (CLI)

Run this once; it's available in every Claude Code session afterward:

claude mcp add --transport http asr-registry https://agent-registry.horizenlabs.io/api/mcp

Works the same in any MCP client that accepts a Streamable HTTP URL.

Already chatting with Claude?

Paste this page's link into the conversation and ask Claude to connect the ASR registry MCP server. Claude will read the endpoint above and walk you through the one-step connection for your client.
