Open a tool for its reasons and full description. Descriptions are the publisher's own words, shown as they are.

  • get_dependenciesGet chart dependencies (sub-charts).No findings

    Why it is in this group

    • The name "get_dependencies" says "get": a word for reading.
    Description, as the server wrote it
    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://).

    Annotations the server declares

    • idempotentHint: false
    • openWorldHint: true
    • readOnlyHint: true
  • get_notesGet chart NOTES.txt (post-install instructions).No findings

    Why it is in this group

    • The name "get_notes" says "get": a word for reading.
    Description, as the server wrote it
    Get chart NOTES.txt (post-install instructions). Supports both HTTP/HTTPS repos and OCI registries (oci://).

    Annotations the server declares

    • idempotentHint: false
    • openWorldHint: true
    • readOnlyHint: true
  • get_valuesGet chart values.yaml with optional JSON schema.No findings

    Why it is in this group

    • The name "get_values" says "get": a word for reading.
    Description, as the server wrote it
    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://).

    Annotations the server declares

    • idempotentHint: false
    • openWorldHint: true
    • readOnlyHint: true
  • get_versionsGet available versions of a chart (newest first).No findings

    Why it is in this group

    • The name "get_versions" says "get": a word for reading.
    Description, as the server wrote it
    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.

    Annotations the server declares

    • idempotentHint: false
    • openWorldHint: true
    • readOnlyHint: true
  • search_chartsList or search charts in a Helm repository.No findings

    Why it is in this group

    • The name "search_charts" says "search": a word for reading.
    Description, as the server wrote it
    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.

    Annotations the server declares

    • idempotentHint: false
    • openWorldHint: true
    • readOnlyHint: true

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. It assumes the server is installed as helm. Review it before you use it.
