Server tool list (5)
Raw names from tools/list. Only developers need these.
| get_dependencies | 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_notes | Get chart NOTES.txt (post-install instructions). Supports both HTTP/HTTPS repos and OCI registries (oci://). |
| get_values | 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 | 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 | 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. |
