🟢get_dependencies(repository_url, chart_name, chart_version)
Get chart dependencies (sub-charts). Each dependency entry includes the dependency's repository URL — 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_values(repository_url, chart_name, chart_version, path, depth, ...)
Get 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_versions(repository_url, chart_name, limit)
Get 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_charts(repository_url, keyword, limit)
List 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 — for OCI you must already know the chart name, then call get_versions or get_values directly with that name.
