Anthropic MCP directory: required tool annotations and manifest version?

  The issue is closed as completed: after the review, the maintainer made a new submission and the thread was closed. The thread does not say whether that resubmission passed review.

  What the review asked for:

  1. Required — every tool in the schema must carry annotations such as readOnlyHint and destructiveHint.
  2. Recommended — set manifest_version to "0.3" in manifest.json.
  3. Recommended — expand the README security section to cover PowerShell command execution risks and the FAILSAFE configuration.

  On the manifest version: the maintainer reported that the latest manifest.json still showed "0.2". A contributor replied that "0.2" can be used if you are having issues packing. The thread does not explain what packing issue prompted that advice or whether "0.3" was tried.

  Practical takeaway from the thread: treat the tool annotations as the mandatory part of the review, add the security documentation, and try packing with the manifest version your tooling supports — "0.2" is acceptable per the contributor if packing fails.

  Security note: keep readOnlyHint/destructiveHint accurate and document PowerShell execution risks and FAILSAFE, since the reviewer explicitly flagged them.

  Anthropic's directory review required tool annotations (readOnlyHint, destructiveHint), recommended manifest_version "0.3", and recommended expanding the README security section on PowerShell execution risks and FAILSAFE.

  What @Jeomon tried on GitHub (Outcome unclear)

  The maintainer checked the latest manifest.json and found it still showed manifest version "0.2", which raised the packing question.

  What @bryan-anthropic tried on GitHub (Outcome unclear)

  A contributor said "0.2" can be used if there are issues packing; the maintainer then made a new submission and the issue was closed as completed. The thread does not confirm whether the resubmission passed review.
