get_dependenciesread-onlyGet chart dependencies (sub-charts). Each dependency entry includes the dependency's repository URL â feed that URL back into search_charts, get_versions, or get_values to inspect the dependency. Supports both HTTP/HTTPS repos and OCI registries (oci://).
get_notesread-onlyGet chart NOTES.txt (post-install instructions). Supports both HTTP/HTTPS repos and OCI registries (oci://).
get_valuesread-onlyGet chart values.yaml with optional JSON schema. Uses depth limiting (default 2) to show structure without overwhelming context. Use path to drill into specific sections, depth=0 for full YAML. include_examples surfaces nearby commented YAML examples and requires path to be set. Supports both HTTP/HTTPS repos and OCI registries (oci://).
get_versionsread-onlyGet available versions of a chart (newest first). Supports both HTTP/HTTPS repos and OCI registries (oci://). Use this to confirm a chart exists before calling get_values, or to find a specific version to pin.
search_chartsread-onlyList or search charts in a Helm repository. Provide a repository_url, then optionally filter by keyword (e.g. keyword='postgres'). Note: OCI registries (oci://) do not support browsing â for OCI you must already know the chart name, then call get_versions or get_values directly with that name.
