Running `@latest` (18.x) against a 17.x site \"works\" until a shape mismatch fails confusingly mid-task. Since the CLI already authenticates against the server, it could fetch the server version once and print a warning (or refuse without `--force`) when majors differ. A docs note recommending `@umbraco-cms/mcp-dev@<site major>` over `@latest` would help too.\n\n## Provenance\n\n- 2026-\n\n[Read the thread](https://github.com/umbraco/Umbraco-CMS-MCP-Dev/issues/426) · 2026-08-22 · open · outside contributor · 2 comments\n\n### create-element-type / create-document-type silently drop description, mandatory, sortOrder on properties\n\n## What should change\n\nThe create tools' property input accepts only `{name, alias, dataTypeId, tab, group}`. Passing `description`, `mandatory`, or `sortOrder` neither errors nor applies — the fields are silently discarded, and the caller only finds out via a follow-up GET. Either support these fields on create (they're standard property metadata, and `update-document-type` accepts them) or reject unknown keys so the caller learns immediately.\n\n## Provenance\n\n- 2026-07-24 — CLI 18.0.0 against U\n\n[Read the thread](https://github.com/umbraco/Umbraco-CMS-MCP-Dev/issues/425) · 2026-08-22 · open · outside contributor · 1 comment\n\n### --call should not wait on stdin: programmatic invocation with piped stdin hangs as an MCP server\n\n## What should change\n\nWhen the CLI is invoked programmatically (e.g. `execFileSync(node, [cliPath, '--call', tool, ...])`) with stdin left open/piped, it waits for MCP protocol input and hangs indefinitely instead of executing the `--call`. Callers must know to pass `stdio: ['ignore', ...]`. When `--call` (or any introspection flag) is present, the CLI should never enter server mode or read stdin.\n\n## Provenance\n\n- 2026-07-24 — CLI 18.0.0, Windows 11 / Node 22: direct invocation hung until stdi\n\n[Read the thread](https://github.com/umbraco/Umbraco-CMS-MCP-Dev/issues/424) · 2026-08-22 · open · outside contributor · 1 comment\n\n### --call-args needs a file/stdin input option: large or non-ASCII inline JSON fails silently on Windows\n\n## What should change\n\n`--call-args` only accepts inline JSON on the command line.
