What your AI can do with agent4.io
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “list_agents”: List all agents in this tenant (name + published state).”
“Use “get_agent”: Get one agent's full configuration (soul/task/tools/skills/knowledge_bases/model/params).”
“Use “create_agent”: Create an agent. `name` is lower-cased on save — it is a key, not a display name. soul = persona/identity; task = duties and bound.”
“Use “update_agent”: Update **part** of an agent — fields you don't pass stay as they are. ⚠️ List-field semantics, don't mix them up: `tools=[...]` / `skil.”
How secure is the agent4.io MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how agent4.io holds up.
Official endpoint
Operated by agent4.io (agent4.io) 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 agent4.io adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.

The agent4.io MCP server at a glance
https://api.agent4.io/v1/mcpQuestions, answered
Is there an official agent4.io MCP server?
Yes — agent4.io operates its own remote MCP server at api.agent4.io. 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 agent4.io to Claude or ChatGPT?
Add gate's gateway URL to your AI client once, then pick agent4.io in the directory. No account or sign-in is needed. From then on, agent4.io's tools are available in every client you've connected to gate.
Do I need to host anything?
No. agent4.io runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
Is the agent4.io 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 agent4.io in minutes. No credit card required.
