What search-profiles does on Nostr Bray
AI agents call search-profiles 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 search-profiles is rated Low
This tool queries existing data (Nostr profile metadata) and returns results. There is no creation, modification, deletion, code execution, or financial action. It is a straightforward read/search operation with minimal risk — the worst case is an AI agent fetching irrelevant profile data or consuming relay bandwidth.
From the tool's definition Tool description states it "search[es] for Nostr profiles", which is a retrieval operation with no side effects. The mechanism is a keyword search query against relay data (NIP-50), returning matching profiles.
Attacks that exploit this kind of access
The rule that runs search-profiles 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 search-profiles, this is the rule to start with:
search-profiles 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 search-profiles call is checked against it from then on.
Questions about search-profiles
Search for Nostr profiles (kind 0) by keyword using NIP-50. Requires relay support for NIP-50 — if results are empty, try relay-info to check NIP support. 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 search-profiles: 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.
search-profiles 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 search-profiles 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 search-profiles. 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.
search-profiles 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.
