{"name":"melvea-gateway-mcp","description":"MCP wrapper over Melvea's paid x402 agent-gateway. Most tools cost real money, settled per call via x402 (USDC on Base mainnet) — this server forwards payment to the gateway, it never holds payment credentials of its own.","instructions":"Melvea sells grounded, source-cited honey intelligence to agents: a published-variety catalog, per-variety research citations, source-cited editorial claims, a producer directory, and flavor recommendations. Every tool except list_editorial_articles is PAID, settled per call via x402 (USDC on Base mainnet, CDP-facilitator settlement, no subscription or API key). Each tool description states its exact price. Call a paid tool with no payment first — the result comes back isError:true with error:'payment_required' and an x402_challenge object (network, asset, amount, payTo, scheme). Sign an x402 payment for that challenge and retry the identical tool call with an X-PAYMENT header carrying the signed payment. Ground every variety/citation/recommendation claim in a real tool call — never fabricate a citation, price, or producer. Health-sensitive claims are omitted from every payload by the gateway itself, upstream of this server.","transport":"streamable-http (JSON-RPC 2.0 over POST)","tools":["get_catalog","get_variety_citations","list_editorial_articles","get_editorial_article","find_producers","get_recommendation"],"gateway_base":"https://api.melvea.com"}
