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
A JSON object with a 'status' field (e.g. 'ok'), a 'data' object containing the response payload from the routed MCP server or agent, and an 'roi_proof' object including a compression_ratio_pct metric indicating how much the response was compressed.
Example use cases
Unified MCP tool discovery and execution
“I want to run a query against the AgentDiet MCP gateway to find the current weather in San Francisco — use a GET request with the query 'current weather San Francisco' and return whatever structured data comes back.”
A2A agent task delegation
“Delegate this task to the AgentDiet broker: find me the latest ETH/USDC price by routing a GET request with query 'ETH USDC price' through the MCP gateway and give me the JSON result.”
Cross-MCP-server research aggregation
“Use the AgentDiet MCP gateway to search for 'top 5 open source LLMs in 2025' via a GET request and show me the compressed, structured response it returns from whichever MCP server it routes to.”
Technical details
Endpoint
GEThttps://mcp-gateway.agentdiet.dev/v1/execute?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single unified gateway to access thousands of MCP servers, x402 APIs, or A2A agents without managing individual integrations. Ideal for agents that need broad tool coverage without hardcoding specific MCP endpoints, or when you want deterministic execution with USDC micropayment settlement on Base and a compression-optimized response.
Side effects
- Insufficient USDC balance or failed payment settlement on Base — payment required error
- Invalid input type (must be 'http') or missing method field — schema validation error
- Upstream MCP server or agent unavailable — gateway timeout or upstream error in data field
- Malformed query parameter — empty or null query returns degraded results
- No matching MCP server found for the query — empty data response with ok status
