Overview

From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.

[](https://skills.sh/arneffm/nowyourlink-agent-kit)

Read the current nowyourlink advertising Spotlight and browse published, settled days. This standalone kit contains an official product skill, portable agent plugin, Codex compatibility manifest, and dependency-free JavaScript SDK and CLI, plus a Python standard-library SDK. Public Spotlight reads need no account or API key. Advertiser actions (bids, creatives, invoices) are delegated: they need an OAuth 2.1 grant that a human advertiser approves, with the spend mandate set on the consent page.

Distribution status: SDKs and CLI published. The public source repository is ArneFfm/nowyourlink-agent-kit. Python SDK and CLI 0.2.0 are published on PyPI. JavaScript SDK and CLI 0.3.0 are published on npm. Install with npm install nowyourlink-agent-kit, or run npx nowyourlink-agent-kit list --limit 5.

MCP registry

The public remote server is published as io.github.ArneFfm/nowyourlink version 1.1.0 in the official MCP Registry. Connect to https://nowyourlink.com/mcp using Streamable HTTP without credentials. server.json retains the published metadata; the registry version describes the remote server, independently of SDK package versions.
