What your AI can do with ArcID
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “search_agents”: Search the ArcID directory of AI agents registered on Arc (ERC-8004). Supports full-text search over names and descriptions, filtering by ow.”
“Use “get_agent”: Full ArcID record for one agent: profile, owner, agent wallet, reputation summary, validations, trust score and the USDC settlement evidence.”
“Use “get_agent_feedback”: Feedback left for an agent in the ERC-8004 Reputation Registry, newest first. Each entry is classified (receipt, rating, metric, self, revok.”
“Use “get_agent_validations”: The latest 100 validation requests and responses for an agent from the ERC-8004 Validation Registry.”
How secure is the ArcID MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how ArcID holds up.
Official endpoint
Operated by ArcID (arcusid.com) at its documented MCP endpoint — not a third-party mirror or community re-host.
No sign-in needed
This server only exposes public data — no account and no credentials are involved when you connect.
Scanned before it goes live
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
Watched for drift
If ArcID adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Connected in three steps

Add one gateway URL to Claude, ChatGPT, or any MCP client. One-time setup, about two minutes.

Who runs the ArcID MCP server?
The ArcID MCP server at a glance
https://mcp.arcusid.com/mcpQuestions, answered
Is there an official ArcID MCP server?
Yes — ArcID operates its own remote MCP server at mcp.arcusid.com. gate connects you to that official endpoint and adds security scanning, per-tool access rules, and an activity log on top.
How do I connect ArcID to Claude or ChatGPT?
Add gate's gateway URL to your AI client once, then pick ArcID in the directory. No account or sign-in is needed. From then on, ArcID's tools are available in every client you've connected to gate.
Do I need to host anything?
No. ArcID runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
Is the ArcID MCP server safe to connect?
It's the vendor's official endpoint, and gate scans its tools for prompt injection and hidden instructions before it goes live, re-checks it whenever it changes, and lets you allow, block, or require approval for every single tool.
Is it free?
Yes — you can get started with gate for free and connect ArcID in minutes. No credit card required.
