Documentation tools and Postman
Use documentation search and the published request collection.
Documentation MCP
The documentation MCP serves documentation search to coding assistants. It does not grant access to merchant accounts, transactions or gateway configuration. claude mcp add --transport http nmi-developer-documentation https://docs.nmi.com/mcp
Keep operational tools separate
The documentation server and the operational NMI MCP are different products. Connecting documentation search does not authorize API operations or provide merchant credentials.
Postman collection
The source publishes a collection for importing request examples. Configure environments and credentials before using imported requests; collection import is not a verified payment test. Open the published Postman collection
