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 proxied response payload, a 'status' field ('ok' on success), and a 'roi_proof' object including a compression_ratio_pct value indicating efficiency of the call.

Example use cases

Unified MCP tool access for agents

“I want to call an MCP server tool without setting up a direct connection — can you send a GET request through the MCP broker gateway to that server URL and bring back the result?”

x402 API call with auto-payment

“There's an x402-gated API I need to hit — route my POST request through the X402-BROKER gateway, let it handle the USDC micropayment on Base, and return whatever data comes back.”

A2A agent task delegation

“I need to delegate a subtask to another AI agent via the MCP gateway — send a GET request to that agent's endpoint and give me the response data along with the compression proof.”

Endpoint

When to prefer

Choose this endpoint when you need a single unified gateway to reach any of 31,390+ MCP servers, x402 APIs, or A2A agents without managing individual connections or payment channels. It is especially useful when your agent needs to dynamically discover and call tools across multiple AI protocols (MCP, x402, L402, MPP, A2A) and wants automatic USDC micropayment handling on Base. Prefer this over direct API calls when you want protocol abstraction and unified billing.

Side effects

Insufficient USDC balance for micropayment settlement — payment rejected
Invalid or unreachable target URL — connection timeout or DNS failure
Unsupported HTTP method supplied (only GET/POST allowed)
Target MCP server or x402 API returns an error — propagated in response
Missing required 'input' field or malformed request schema — 400 validation error
Network congestion on Base causing settlement delay
