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 routed response, a 'status' field ('ok' on success), and a 'roi_proof' object including a compression_ratio_pct value (e.g. 91.4%) indicating how much the response was compressed relative to raw upstream data.
Example use cases
Discover best MCP tool for a task
“Find the best available MCP server that can extract structured data from PDFs — query the AgentDiet MCP router with 'PDF data extraction' and return what it recommends.”
Route an agent task to A2A network
“I need to delegate a sentiment analysis job to another agent in the network — send a GET request through the MCP gateway with query 'sentiment analysis agent' and tell me what comes back.”
Find x402 API for image generation
“Search the MCP gateway for any x402 API that does image generation — use a GET query for 'image generation' and show me the top result and its compression proof.”
Technical details
Endpoint
GEThttps://mcp-gateway.agentdiet.dev/v1/mcp-router?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single unified gateway to discover and invoke capabilities across a large catalog of MCP servers, x402 APIs, and A2A agents without managing individual integrations. It is best suited for agents that need to dynamically route tasks to the most appropriate backend at runtime, especially when USDC micropayment settlement on Base is acceptable. Prefer over direct API calls when the target capability is unknown in advance and discovery is part of the workflow.
Side effects
- Query parameter missing or malformed — returns error status
- Payment not settled or USDC balance insufficient — 402 Payment Required response
- No matching MCP server or API found for the given query — empty data response
- Upstream MCP server or x402 API unavailable — propagated error in data field
- Invalid method enum value (not GET or POST) — schema validation error
