What social-post does on Nostr Bray
AI agents use social-post 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 social-post is rated Medium
This tool creates and publishes new data (a social post) to a distributed network with cryptographic signing, making it a Write operation. It is classified as 'high' severity because: (1) posts are publicly visible and attributed to the user's identity, (2) the action is reversible only through protocol-specific deletion mechanisms (not guaranteed across all relays), (3) misuse by an AI agent could result in spam,…
From the tool's definition Post a text note (kind 1) signed by the active identity and publish to relays. Returns { id, pubkey, publish: { success, allAccepted, accepted, rejected } }.

The rule that runs social-post 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 social-post, this is the rule to start with:
social-post 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 social-post call is checked against it from then on.
Questions about social-post
Post a text note (kind 1) signed by the active identity and publish to relays. Returns { id, pubkey, publish: { success, allAccepted, accepted, rejected } } where success is the majority-quorum signal (true when at least one relay accepted and at least half of attempted relays accepted) and allAccepted is true only when every attempted relay accepted. The most common social action. 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 social-post: 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.
social-post 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 social-post 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 social-post. 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.
social-post 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.
