@helloaigent-dev/subscriber

The Hello Aigent reference subscriber — an MCP server that lets any agent subscribe to any Hello Aigent feed, fetch signed updates, verify them, and act on them.

npx @helloaigent-dev/subscriber

Tool

What it does

hello_aigent_subscribe(discovery_url, feed_id?, principal, consent_scope)

Reads the site's /.well-known/hello-aigent.json, subscribes on behalf of your principal

hello_aigent_fetch(subscription_id?, max?)

Pulls only-new-since updates via the stored cursor; verifies every envelope signature

hello_aigent_unsubscribe(subscription_id)

Revokes consent (idempotent)

hello_aigent_list_subscriptions()

Lists stored subscriptions (tokens are never exposed)

Guarantees

  • Signature verification before anything is actionable. Envelopes are Ed25519-verified (RFC 8785 JCS canonicalization) against the feed's discovery public key. Anything that fails verification is returned under unverified with its actions stripped.

  • Consent is surfaced. Subscribing records the principal and consent_scope; the tool description instructs agents to confirm with their principal first.

  • Local state only. Subscriptions (including bearer tokens) live in ~/.hello-aigent/subscriptions.json (mode 0600). Override with HELLO_AIGENT_STATE.
