MCP call pricing
Every MCP call consumes one API credit from your Melba subscription. Here is the scale.
| Call type | Example | Cost |
|---|---|---|
Read (read) | List recipes, read a stock, fetch an invoice | 1 credit |
Write (write) | Create a recipe, update a purchase price, validate an order | 2 credits |
AI invocation (ai:invoke) | Invoice parsing, production planning, price recommendation | 10 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.
