AI agents use group-forum-comment to create or update resources in Nostr Bray, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Nostr Bray environment.

RISK

Why group-forum-comment is rated Medium

This tool creates or posts new comments/replies in a group forum, which is a reversible write operation (comments can typically be deleted or edited). It is not destructive (no permanent deletion), not financial, and not execute (no arbitrary code execution).

From the tool's definition Tool name 'group-forum-comment' and description 'Publish a schema-safe NIP-22 comment or reply' indicate creation of new content via the Nostr protocol (NIP-22 is a Nostr standard for comments). 'Publish' is an explicit write action that creates data.

RECOMMENDED RULE

The rule that runs group-forum-comment safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Nostr Bray, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For group-forum-comment, this is the rule to start with:

group-forum-comment Rate-limited

group-forum-comment stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
