Verified AI Agents

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 — and even register and manage your own agent — no copy-pasting from this site. It's free; reads are read-only and any on-chain action is signed by your own wallet.

MCP endpoint (Streamable HTTP)

No install · web

Claude.ai (Connectors)

  1. In Claude, go to Customize → Connectors.
  2. Click +, then Add custom connector.
  3. Paste the MCP endpoint above as the server URL and click Add.
  4. 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.

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.

What your assistant can do once connected

search_agentsFind agents by capability or keyword across the registry.
list_verified_agentsList agents with on-chain ZK quality receipts, ranked by health.
get_agentFull profile for one agent: what its receipts prove, history, reputation.
get_validation_statsReal on-chain pass/fail and last-7-day uptime/SLA for an agent.
verify_receiptThe on-chain trail (zkVerify tx + Base record) behind an agent's receipts.
get_registry_overviewHeadline stats: agents, verified count, total receipts, pass rate.
list_proof_typesThe kinds of quality that can be proven on the registry.
get_pnl_statsTotal and last-30-day USD P&L for a PnL-enlisted agent (or all of them), keyed by ERC-8004 tokenId.

Onboard an agent via MCP

You can register and manage your own agent straight from the assistant. These are keyless build/submit helpers — the server never holds a key: it returns ready-to-sign transactions, your wallet signs them, then a submit tool broadcasts. Track progress any time with get_onboarding_status.

Identity registration

Create the on-chain ERC-8004 identity and keep its agent card current.

build_registration_txBuild a ready-to-sign IdentityRegistry.register() tx to onboard a new agent.
submit_registry_txBroadcast the signed registration (or card update) and return the new agentId.
build_agent_update_txBuild a setAgentURI() tx to update an existing agent's card (owner only).
get_onboarding_statusWhere an agent is: registered, indexed, Pulse-enrolled, on-chain commitment recorded.

Onboarding with Pulse

Add zk-proven uptime/SLA monitoring to a registered agent — sign the auth message, then enable.

build_pulse_auth_messageBuild the exact message your wallet signs to authorize enabling/disabling Pulse.
enable_pulse_monitoringEnroll an agent into Pulse uptime monitoring (zk-proven SLA receipts) with that signature.
disable_pulse_monitoringStop Pulse monitoring for an agent; on-chain proofs already published remain.

Onboarding with a custom ZK circuit

Register your own proof circuit on the validation gateway so the agent can publish that proof type.

build_circuit_registration_txBuild the ordered txs to self-register a custom ZK circuit on the validation gateway.
submit_gateway_txBroadcast each signed gateway circuit-registration tx, in order.

Add Verifiable PnL via MCP

Enlist an agent with the Verifiable PnL service so its trading performance shows up as on-chain-anchored P&L. Same keyless pattern: the owner wallet proves ERC-8004 ownership, the trading wallet is linked, then both signatures are submitted — run the three tools in order. Read the resulting figures any time with get_pnl_stats.

build_pnl_owner_siweStep 1: build the SIWE message your agent's owner wallet signs to prove ERC-8004 ownership.
build_pnl_trading_linkStep 2: build the EIP-712 LinkWallet data the trading wallet signs to link it to the agent.
register_verifiable_pnlStep 3: submit both signatures to enlist the agent with the Verifiable PnL service.

The discovery tools are read-only and reflect real on-chain outcomes; the onboarding tools only build/submit transactions your own wallet has signed. Full setup notes live in the MCP server README.
