Struct ClientPubkey 

pub struct ClientPubkey(pub String);

The Nostr public key (hex) of the client that issued the current request.

NostrServerWorker injects this into every inbound request’s rmcp extensions typemap, so a tool, resource, or prompt handler can identify its caller:

use contextvm_sdk::transport::server::ClientPubkey;
use rmcp::service::RequestContext;
use rmcp::RoleServer;

let caller = ctx.extensions.get::<ClientPubkey>().map(|c| c.0.clone());

The value is the raw hex pubkey (the same string as IncomingRequest::client_pubkey). It is present on every real inbound request, unlike OpenStreamWriter, which is injected only for open-stream tools/call calls. This is purely a local affordance — it is never serialized onto the wire. The inbound Nostr event id is available separately as the rmcp request id (ctx.id), which the worker rewrites to the event id.
