What trust-ring-prove does on Nostr Bray
AI agents invoke trust-ring-prove to trigger actions in Nostr Bray. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
Why trust-ring-prove is rated High
Ring signature creation is a cryptographic execution operation: it computes and produces a proof artifact. It doesn't simply read data, nor does it write persistent user data in the traditional sense, nor is it destructive or financial. The primary action is executing a cryptographic protocol to generate a verifiable output.
From the tool's definition 'Create a ring signature proving anonymous group membership' — generates a cryptographic proof, triggering an external cryptographic operation whose output (a ring signature) can be used to assert identity or membership claims
Attacks that exploit this kind of access
The rule that runs trust-ring-prove 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 trust-ring-prove, this is the rule to start with:
trust-ring-prove stays usable, but rate-capped: a runaway agent can't fire it dozens of times 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 trust-ring-prove call is checked against it from then on.
Questions about trust-ring-prove
Create a ring signature proving anonymous group membership. A verifier can confirm. It is categorised as a Execute tool in the Nostr Bray MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Nostr Bray MCP server in PolicyLayer and add a rule for trust-ring-prove: 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.
trust-ring-prove is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the trust-ring-prove 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 trust-ring-prove. 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.
trust-ring-prove 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.
