# AgentDiet MCP Compiler Gateway

> AgentDiet MCP Compiler Gateway is a paid API for AI agents from mcp-gateway.agentdiet.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-22).

Routes and compiles HTTP requests to 31,390+ MCP servers, x402 APIs, and A2A agents via a unified broker endpoint, settling payments in USDC on Base.

## Facts

- Endpoint: GET https://mcp-gateway.agentdiet.dev/v1/mcp-compiler?utm_source=zero.xyz
- Price: $0.01/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-compiler-gateway-c0ecd653
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_x3F9sEaiSQTKqrVbaRlVN

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-compiler-gateway-c0ecd653
```

Example prompt: Route a GET request to the target MCP server for weather data through the AgentDiet broker — compile it and settle the $0.01 USDC fee on Base.

## When to prefer this

Choose this endpoint when you need a single unified gateway to reach any of 31,390+ MCP servers, x402 APIs, or A2A agents without setting up individual integrations. Ideal for agents that need deterministic routing, automatic micropayment settlement in USDC on Base, and support for MCP, x402, MPP, and L402 protocols in one call. Prefer over direct API integrations when breadth of tool access matters more than deep single-API optimization.

## Known failure modes

- Target MCP server or API unavailable — returns error status
- Insufficient USDC balance for $0.01 settlement — payment failure
- Invalid or missing 'input.type' or 'input.method' fields — schema validation error
- Unsupported HTTP method (only GET/POST allowed) — enum validation failure
- Target query parameter missing or malformed — routing failure
- Base network congestion causing settlement delay

## How this service works

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

## Output

Returns a JSON object with a 'data' field containing the compiled response from the target MCP server or API, a 'status' field (e.g. 'ok'), and an 'roi_proof' object including a compression_ratio_pct metric demonstrating efficiency of the routing.
