@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

"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:

{
  "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?"
