# AgentDiet MCP Security Node

> AgentDiet MCP Security Node is a paid API for AI agents from status.agentdiet.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-22).

Checks the security status of the AgentDiet MCP (Model Context Protocol) node, returning compressed context with compression ratio proof

## Facts

- Endpoint: GET https://status.agentdiet.dev/v1/mcp-security?utm_source=zero.xyz
- Price: $0.005/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-22
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/agentdiet-mcp-security-node-eb1f1425
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_Sl1KThBMHvfgqR1uZHpBJ

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability agentdiet-mcp-security-node-eb1f1425
```

Example prompt: Check the security status of the AgentDiet MCP node and show me the compression ratio proof it returns.

## When to prefer this

Use this endpoint when you need to verify the operational and security status of the AgentDiet MCP node specifically, or when you want to retrieve compression ratio proof (roi_proof) as evidence of context window reduction efficiency. Best suited for agents that are monitoring their AI infrastructure or auditing token-cost savings from context distillation pipelines. Not a general-purpose security scanner — it is scoped to this specific node.

## Known failure modes

- Payment not included or insufficient USDC — returns HTTP 402 Payment Required
- Node offline or overloaded — returns non-ok status or connection timeout
- Invalid method passed — only GET and POST accepted
- Missing required 'input.type' or 'input.method' fields — returns validation error
- Network issues reaching status.agentdiet.dev — connection refused or DNS failure

## How this service works

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

## Output

Returns a JSON object with a 'status' field (e.g. 'ok'), a 'data' object with node details, and an 'roi_proof' object containing a 'compression_ratio_pct' metric (e.g. 91.4%) demonstrating how much token compression was achieved.
