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 execution result, a 'status' field (e.g. 'ok'), and an 'roi_proof' object including a compression_ratio_pct metric (e.g. 91.4%) demonstrating efficiency of the brokered call.
Example use cases
Single gateway for MCP tool calls
“I want to run a query against an MCP server without integrating it directly — can you send the query 'list available databases' as a GET request through the AgentDiet broker and pay the USDC fee automatically?”
x402 API access with micropayment
“Call an x402-enabled API through the AgentDiet broker with a POST request using my query — I want to fetch company enrichment data and have the $0.01 USDC fee settled on Base.”
A2A agent task delegation
“Delegate this task to an external A2A agent via the MCP gateway broker — send 'summarize the latest news on AI regulation' as a GET query and settle the micropayment in USDC on Base.”
Technical details
Endpoint
GEThttps://mcp-gateway.agentdiet.dev/v1/broker/execute?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs a single, unified gateway to access a large catalog of MCP servers, x402 APIs, or A2A agents without maintaining individual integrations, and when USDC micropayment settlement on Base is acceptable. Prefer this over direct MCP server integration when breadth of access (31,390+ servers) matters more than deep, specialized integration with a single provider.
Side effects
- Insufficient USDC balance on Base — payment settlement fails
- Invalid or unsupported HTTP method passed (only GET or POST allowed)
- Missing required 'input.type' or 'input.method' fields — schema validation error
- Target MCP server or x402 API unavailable or rate-limited
- Query parameter malformed or empty — downstream execution fails
- Network timeout reaching mcp-gateway.agentdiet.dev
