The Kconfig database is an always-enabled Nordic MCP feature.
It provides structured, authoritative symbol discovery and source-level details.
Its tools use the kconfig_* namespace.
The Kconfig database supports these tasks:
- Semantic or keyword symbol search
- Exact symbol details
- Dependencies, defaults, and source-level constraints
- Source locations
For example:
Use the Kconfig tools and Nordic documentation to find the settings required for asynchronous UART on nRF54L15 in the nRF Connect SDK v3.3.0.
Explain each dependency before changing prj.conf.
