Agent Interface Standard

Schema.org for AI Agents — the open standard for how businesses describe their services to AI agents.

The Vision

Schema.org made websites machine-readable for search engines. Agent Interface Standard makes businesses machine-readable for AI agents.

Businesses publish a simple JSON spec at /.well-known/agent-interface.json describing what services they offer and how agents can interact with them.

Installation

pip install agent-interface-standard

{"mcpServers": {"agent-interface": {"command": "uvx", "args": ["agent-interface-standard"]}}}

Tools

Tool	Description
get_spec_template	Get a blank template to fill out

validate_interface_spec	Check your spec for errors

The Spec Format

{
  "agent_interface": "0.1.0",
  "business": {
    "name": "My Business",
    "description": "What we do",
    "category": "e_commerce"
  },
  "capabilities": [
    {
      "name": "search_products",
      "description": "Search our product catalog",
      "type": "search",
      "endpoint": "https://api.mybusiness.com/search",
      "method": "GET",
      "parameters": [...]
    }
  ],
  "auth": {"type": "api_key"},
  "pricing": {"model": "freemium"}
}

Why This Matters

When AI agents become primary customers (not just humans), businesses need a standard way to be "agent-accessible." This is that standard.
