WHAT IT DOES

What social-profile-set does on Nostr Bray

AI agents use social-profile-set 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 social-profile-set is rated Medium

This tool modifies (creates or updates) a Nostr kind 0 profile, which is user profile metadata. While the action is reversible (profiles can be changed again), it affects identity/reputation data and requires confirmation to overwrite, placing it in the Write category rather than Read.

From the tool's definition "Set the kind 0 profile for the active identity" and "set confirm: true to overwrite" indicates the tool creates or modifies profile data. The warning about existing profiles and explicit overwrite mechanism confirms it performs a reversible write operation.

RECOMMENDED RULE

The rule that runs social-profile-set 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-profile-set, this is the rule to start with:

social-profile-set Rate-limited

social-profile-set 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.
