What social-reply does on Nostr Bray
AI agents use social-reply 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.
Why social-reply is rated Medium
This tool creates a new reply post on the Nostr social network, which is a reversible write operation (publishing content). It does not delete, execute code, or involve financial transactions. Misuse could result in unwanted public replies or spam, giving it medium severity.

Attacks that exploit this kind of access
The rule that runs social-reply 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 social-reply, this is the rule to start with:
social-reply 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Nostr Bray, apply this rule, and every social-reply call is checked against it from then on.
