@helloaigent-dev/publisher

Hello Aigent publisher MCP — an MCP server that lets an agent run a publisher's feed: create feeds, publish signed updates, and read analytics. The producer-side counterpart to @helloaigent-dev/subscriber (which lets an agent subscribe/fetch/act).

A marketer operates their owned agent audience by telling their agent — no CLI, console, or developer.

Tools

Tool	Auth	What it does
`hello_aigent_create_feed`	workspace key or admin	Mint a feed + Ed25519 keypair + publisher token; returns the discovery file
`hello_aigent_list_feeds`	workspace key or admin	List feeds you own
`hello_aigent_publish`	publish token, workspace key, or admin	Build + server-sign an update; delivered to subscribers
`hello_aigent_report_event`	publish token, workspace key, or admin	Report an action outcome (the "acted" analytics signal)
`hello_aigent_overview`	workspace key or admin	KPI tiles, fetch sparkline, recent activity
`hello_aigent_funnel`	workspace key or admin	subscribed → returned → acted funnel
`hello_aigent_event_log`	workspace key or admin	Filterable, attributed audit log
`hello_aigent_subscribers`	workspace key or admin	The owned-audience list (consent-aware)
`hello_aigent_discovery_file`	public	Generated `hello-aigent.json` to host at `/.well-known/`

"workspace key" means a hak_... workspace API key — mint one from the Hello Aigent console (Settings → API keys) once you've signed up. It scopes every tool above to your own workspace: create_feed creates in your workspace, list_feeds/analytics/subscribers only ever see feeds your workspace owns, and publish/report_event only work on feeds your workspace owns. It is not admin-equivalent — it cannot create, list, or revoke API keys (that requires signing in to the console itself).

The admin token is a separate, unrestricted, ops-only credential (not something a self-serve signup ever receives) — it still works everywhere a workspace key does, for every feed, not just your own.

Configure

Set in your MCP client config (env vars):

HELLOAIGENT_API — API base (default https://api.helloaigent.dev)
HELLOAIGENT_API_KEY — your workspace API key (hak_...); required for feed management + analytics unless using the admin token. Preferred over HELLOAIGENT_ADMIN_TOKEN when both are set.
HELLOAIGENT_ADMIN_TOKEN — admin token; alternative to HELLOAIGENT_API_KEY (ops/dogfood use only)
HELLOAIGENT_TOKEN — publish token (a feed's own publisher token); falls back to HELLOAIGENT_API_KEY, then HELLOAIGENT_ADMIN_TOKEN

Example (Claude Desktop / any MCP client) — the common case, a self-serve workspace key:

config.json

{
  "mcpServers": {
    "hello-aigent-publisher": {
      "command": "npx",
      "args": ["-y", "@helloaigent-dev/publisher"],
      "env": { "HELLOAIGENT_API_KEY": "hak_…" }
    }
  }
}

Then just ask your agent: "Create a feed for my coffee shop and publish a restock update," or "How many agents subscribed this week, and what's the return rate?"
