What encode-naddr does on Nostr Bray
AI agents call encode-naddr to retrieve information from Nostr Bray without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why encode-naddr is rated Low
The tool performs a deterministic encoding transformation (Nostr event reference to bech32 format). This is a read-only computational operation with no ability to modify data, execute commands, or trigger external effects. It returns an encoded representation and produces no side effects.
From the tool's definition Tool description states 'Encode an addressable event reference as a bech32 naddr' — this is purely an encoding/formatting operation with no side effects, data retrieval, or external modifications.
Attacks that exploit this kind of access
The rule that runs encode-naddr 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 encode-naddr, this is the rule to start with:
encode-naddr is read-only, so it stays allowed. 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 encode-naddr call is checked against it from then on.
Questions about encode-naddr
Encode an addressable event reference as a bech32 naddr. It is categorised as a Read tool in the Nostr Bray MCP Server, which means it retrieves data without modifying state.
Register the Nostr Bray MCP server in PolicyLayer and add a rule for encode-naddr: 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.
encode-naddr is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the encode-naddr 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 encode-naddr. 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.
encode-naddr 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.
