What encode-nevent does on Nostr Bray
AI agents call encode-nevent 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-nevent is rated Low
The encode-nevent tool performs a read-only encoding transformation on provided parameters (event ID, relay hints, author). It retrieves no data beyond what is supplied as input and has no capability to modify, create, or destroy any state. This is purely a computational utility for formatting data in bech32 format, consistent with the Read category for tools that transform or format data without side effects.
From the tool's definition Tool description states it 'Encode[s] an event ID with relay hints and optional author as a bech32 nevent.' This is a data transformation/encoding operation with no side effects.
Attacks that exploit this kind of access
The rule that runs encode-nevent 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-nevent, this is the rule to start with:
encode-nevent 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-nevent call is checked against it from then on.
Questions about encode-nevent
Encode an event ID with relay hints and optional author as a bech32 nevent. 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-nevent: 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-nevent 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-nevent 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-nevent. 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-nevent 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.
