List the environments (Spring profiles) auto-discovered from this repository's application/bootstrap files, with each environment's Nacos server address, namespace and groups. Call this first if you are unsure which environments exist.

Read the raw content of one Nacos config by its exact dataId (e.g. 'order-service.properties'). Use nacos_search_config first when you don't know which dataId contains a key.

Read the effective configuration of one application: its own config (.) plus the shared/extension configs declared in the project (spring.cloud.nacos.config.shared-configs). Prefer this over nacos_get_config when asked about an app's settings.

List config dataIds in an environment's namespace (no content by default). Optionally fuzzy-filter by dataId substring.

Full-text search across all config contents in one environment. Returns matching dataIds with the matching lines. Use this to find which config file defines a property key.

Compare one config (dataId) between two environments and return a structured key-level diff: keys only in A, only in B, and changed values. The best tool for questions like 'is X consistent between dev and test?'.

List service names registered in the Nacos naming/discovery registry of one environment.

List the online instances (IP, port, health) of one service. Use for 'is service X up / why is it offline' questions.
