What privacy-publish-proof does on Nostr Bray
AI agents use privacy-publish-proof 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 privacy-publish-proof is rated Medium
The tool publishes cryptographic proofs to Nostr, creating new events that are immutable once written. This is a Write operation (creates data) rather than Destructive (no deletion/overwrite of existing records).
From the tool's definition Publish a range proof as a kind 30078 (NIP-78) Nostr event—this creates and publishes data to a decentralized social network.
Attacks that exploit this kind of access
The rule that runs privacy-publish-proof 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 privacy-publish-proof, this is the rule to start with:
privacy-publish-proof 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 privacy-publish-proof call is checked against it from then on.
Questions about privacy-publish-proof
Publish a range proof as a kind 30078 (NIP-78) Nostr event. Includes the commitment, proof, range description, and optional subject pubkey. The proof can then be discovered and verified by anyone. It is categorised as a Write tool in the Nostr Bray MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Nostr Bray MCP server in PolicyLayer and add a rule for privacy-publish-proof: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Nostr Bray. Nothing to install.
privacy-publish-proof is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the privacy-publish-proof rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for privacy-publish-proof. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
privacy-publish-proof is provided by the Nostr Bray MCP server (nostr-bray). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
