What does it mean that mcp-gateway.agentdiet.dev is verified for UCP?

It means mcp-gateway.agentdiet.dev publishes a valid UCP profile at /.well-known/ucp, the profile passes schema validation against 2026-08-25, and AI agents can discover its commerce capabilities without needing to scrape HTML. That is what the store declares. Whether an agent actually completes a purchase is a separate question — where an observed agent run is shown on this page, it answers that one.

Can I trust mcp-gateway.agentdiet.dev for AI agent purchases?

Verified means the store publishes a UCP profile at /.well-known/ucp that passes schema validation, with its services and payment handlers declared. Where we call a service, such as asking an MCP service for its tools, this page shows the answer; services we did not call are marked as declared only. It doesn't grade business reputation or fulfilment quality. For trust on the commerce side itself, check the store's own reviews. For the agent integration side, this page shows what the store's UCP profile declares and whether it validates.

What platform does mcp-gateway.agentdiet.dev use for UCP?

Our detection identifies mcp-gateway.agentdiet.dev as running on Shopware. Many large UCP-verified stores use Shopify, BigCommerce, or custom stacks built on the open spec. The transport list above shows the exact mechanism (REST, MCP, A2A, Embedded) the profile declares.

How was this UCP report for mcp-gateway.agentdiet.dev generated?

Our crawler fetches mcp-gateway.agentdiet.dev/.well-known/ucp directly, parses the profile against the official UCP JSON schema, checks robots.txt for its rules for AI crawlers, and runs payment-handler validation. No manual review, no opinions — just what the profile actually says. The check ran 7 hours ago.

How do I get a newer result for mcp-gateway.agentdiet.dev?

This page shows the stored result of our last check and when it was observed. To run a new check, use Check again on this page.

Why does this status matter?

Universal Commerce Protocol is an open standard that lets a UCP agent find out what a store sells, build a cart and check out through a published contract instead of reading web pages. A valid UCP profile is how a store declares that support.

# Agent Authentication & Authorization Guide (mcp-gateway.agentdiet.dev)

> WorkOS `auth.md` v1.0 & RFC 9728 / RFC 8414 / x402 v2 / IETF MPP machine-readable authentication specification for `https://mcp-gateway.agentdiet.dev`.

## Discover

Autonomous agents can discover authentication and payment metadata at:

- **OAuth 2.0 Issuer (`issuer`):** `https://mcp-gateway.agentdiet.dev`
- **OAuth 2.0 Token Endpoint (`token_endpoint`):** `https://mcp-gateway.agentdiet.dev/oauth/token`
- **Personal Agent Protocol Discovery (`poppy.json`):** `https://mcp-gateway.agentdiet.dev/.well-known/poppy.json`
- **Protected Resource Metadata (RFC 9728):** `https://mcp-gateway.agentdiet.dev/.well-known/oauth-protected-resource`
- **Authorization Server Metadata (RFC 8414 + `agent_auth`):** `https://mcp-gateway.agentdiet.dev/.well-known/oauth-authorization-server`
- **Web Bot Auth Directory (RFC 9421):** `https://mcp-gateway.agentdiet.dev/.well-known/http-message-signatures-directory`
- **Agent Identity Endpoint (`identity_endpoint`):** `https://mcp-gateway.agentdiet.dev/agent/identity`
- **Agent Claim Endpoint (`claim_endpoint`):** `https://mcp-gateway.agentdiet.dev/agent/claim`
- **Agent Events Endpoint (`events_endpoint`):** `https://mcp-gateway.agentdiet.dev/agent/events`
- **Protected Auth Challenge Probe:** `https://mcp-gateway.agentdiet.dev/agent/auth` (emits `WWW-Authenticate: Bearer resource_metadata="https://mcp-gateway.agentdiet.dev/.well-known/oauth-protected-resource"`)

## Pick a method

Choose the authentication or settlement flow matching your agent runtime:

1. **`anonymous` (Free Sandbox Preview):** Call `GET https://mcp-gateway.agentdiet.dev/v1/try/distill` or `POST https://mcp-gateway.agentdiet.dev/mcp` (`tools/list`, `resources/list`, `prompts/list`) with no credentials required.
2. **`identity_assertion` (ID-JAG / OAuth 2.0 Token Exchange):** Present an `urn:ietf:params:oauth:token-type:id-jag` assertion to `https://mcp-gateway.agentdiet.dev/agent/identity` or `https://mcp-gateway.agentdiet.dev/v1/billing/topup`.
3. **`service_auth` (Session Key / Bearer Token / x402 / MPP):** Authenticate with `Authorization: Bearer <access_token>`, `PAYMENT-SIGNATURE` (x402 v2 Base USDC to `0xEC5275D5b03bc390FcA63D902d0B2D0Db2eb5573`), or `Authorization: Payment` (IETF MPP).

## Register

Register an autonomous agent identity dynamically with zero human intervention:

```bash
curl -sS -X POST https://mcp-gateway.agentdiet.dev/agent/identity   -H "Content-Type: application/json"   -d '{"agent_name":"autonomous-worker-01","identity_type":"identity_assertion","assertion_type":"urn:ietf:params:oauth:token-type:id-jag"}'
```

## Claim

Link or claim an existing agent identity or human workspace session via `claim_endpoint`:

```bash
curl -sS -X POST https://mcp-gateway.agentdiet.dev/agent/claim   -H "Content-Type: application/json"   -d '{"agent_id":"ag_01","claim_token":"clm_demo"}'
```

## Exchange

Exchange an `identity_assertion` (`urn:ietf:params:oauth:token-type:id-jag`) or `service_auth` credential for an `access_token` at the token endpoint:

```bash
curl -sS -X POST https://mcp-gateway.agentdiet.dev/v1/billing/topup   -H "Content-Type: application/json"   -d '{"grant_type":"urn:ietf:params:oauth:grant-type:token-exchange","subject_token_type":"urn:ietf:params:oauth:token-type:id-jag","subject_token":"eyJ..."}'
```

## Use the access_token

Include the `access_token` in the `Authorization: Bearer <access_token>` header on API or MCP calls:

```bash
curl -sS https://mcp-gateway.agentdiet.dev/agent/auth   -H "Authorization: Bearer agd_live_session_token"
```

## Errors

Unauthenticated requests to `https://mcp-gateway.agentdiet.dev/agent/auth` return `HTTP 401 Unauthorized` with `WWW-Authenticate: Bearer resource_metadata="https://mcp-gateway.agentdiet.dev/.well-known/oauth-protected-resource"` and an `application/problem+json` body. Paid endpoints (`/v1/*`) without payment headers return `HTTP 402 Payment Required` with x402 v2 and IETF MPP challenges.

## Revocation

Revoke an active `access_token` or session pass at any time by calling `DELETE https://mcp-gateway.agentdiet.dev/agent/identity` or `POST https://mcp-gateway.agentdiet.dev/agent/events` with `{"event":"token.revoke"}`.

# MCP-GATEWAY.AGENTDIET.DEV — Autonomous B2A, A2A, MCP & x402 Node

> Deterministic B2A/A2A/MCP/x402/MPP/L402 execution and intelligence node at https://mcp-gateway.agentdiet.dev settling in USDC on Base.

## Installation

Install the skill or connect directly via curl, Python, ESM JavaScript, or Hermes CLI:

```bash
hermes skills install https://mcp-gateway.agentdiet.dev/SKILL.md --name mcp-gateway-agentdiet-dev
curl -sS https://mcp-gateway.agentdiet.dev/v1/try/mcp-gateway
```

## Configuration

Add `mcp-gateway-agentdiet-dev` to your MCP client configuration (`claude_desktop_config.json`, `.cursor/mcp.json`, or Gemini CLI):

```json
{
  "mcpServers": {
    "mcp-gateway-agentdiet-dev": {
      "type": "streamable-http",
      "url": "https://mcp-gateway.agentdiet.dev/mcp"
    }
  }
}
```

## Usage

Call the free sandbox preview (`/v1/try/mcp-gateway`), the paid x402 v2 / IETF MPP endpoint (`/v1/mcp-gateway`), or the A2A v0.3.0 JSON-RPC 2.0 endpoint (`POST https://mcp-gateway.agentdiet.dev/a2a`):

```json
{
  "jsonrpc": "2.0",
  "id": "1",
  "method": "message/send",
  "params": {
    "message": {
      "role": "user",
      "parts": [
        {
          "kind": "text",
          "text": "Execute mcp-gateway on mcp-gateway.agentdiet.dev"
        }
      ]
    }
  }
}
```
