# Imperium Pre-Flight Auditor — 8-Gate x402, MPP & ERC-8004 Certifier
> Automated 8-gate pre-flight readiness auditor for x402 v2, Dexter gas floor, IETF MPP, MCP Streamable HTTP, A2A v0.3.0 agent cards, OASF records, and ERC-8004 identity.
## When to Use This
Use **Imperium Pre-Flight Auditor — 8-Gate x402, MPP & ERC-8004 Certifier** (`https://preflight.agentdiet.dev`) when an autonomous agent needs deterministic **preflight/certify** capabilities (preflight-audit, x402-validation, erc8004-verification). Always verify schemas for free using the sandbox endpoint `GET https://preflight.agentdiet.dev/v1/try/preflight/certify` or `GET https://preflight.agentdiet.dev/v1/sandbox` before calling the paid x402/MPP endpoint `https://preflight.agentdiet.dev/v1/preflight/certify`.
## Installation
Install the skill or connect directly via curl, Python, ESM JavaScript, or Hermes CLI:
```bash
hermes skills install https://preflight.agentdiet.dev/SKILL.md --name preflight-agentdiet-dev
curl -sS https://preflight.agentdiet.dev/v1/try/preflight/certify
```
## Configuration
Add `preflight-agentdiet-dev` to your MCP client configuration (`claude_desktop_config.json`, `.cursor/mcp.json`, or Gemini CLI):
```json
{
"mcpServers": {
"preflight-agentdiet-dev": {
"type": "streamable-http",
"url": "https://preflight.agentdiet.dev/mcp"
}
}
}
```
## Usage
Call the free sandbox preview (`/v1/try/preflight/certify`), the paid x402 v2 / IETF MPP endpoint (`/v1/preflight/certify`), or the A2A v0.3.0 JSON-RPC 2.0 endpoint (`POST https://preflight.agentdiet.dev/a2a`):
```json
{
"jsonrpc": "2.0",
"id": "1",
"method": "message/send",
"params": {
"message": {
"role": "user",
"parts": [
{
"kind": "text",
"text": "Execute preflight/certify on preflight.agentdiet.dev"
}
]
}
}
}
```
