What wiki-publish does on Nostr Bray
AI agents use wiki-publish 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 wiki-publish is rated Medium
This tool creates or modifies wiki article data via Nostr events. It is reversible (subsequent publishes overwrite prior content) and collaborative, making it Write rather than Destructive. The medium severity reflects that malicious actors could pollute wiki content, but the replaceable nature and collaborative consensus mechanism limit blast radius compared to irreversible deletion or financial moves.
From the tool's definition 'Publish or update a wiki article' — creates or modifies data; 'Creates a replaceable event' indicates mutation; 'anyone can publish a revision for the same topic' confirms write capability without deletion.
Attacks that exploit this kind of access
The rule that runs wiki-publish 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 wiki-publish, this is the rule to start with:
wiki-publish 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 wiki-publish call is checked against it from then on.
