MCP call pricing

Every MCP call consumes one API credit from your Melba subscription. Here is the scale.

Call typeExampleCost
Read (read)List recipes, read a stock, fetch an invoice1 credit
Write (write)Create a recipe, update a purchase price, validate an order2 credits
AI invocation (ai:invoke)Invoice parsing, production planning, price recommendation10 credits

What about macros / workflows?

A macro chaining several sub-calls is billed as the sum of its sub-calls. Example: "reorder my stocks" = read stocks (1) + read history (1) + write order (2) = 4 credits.

How to monitor your usage
