Common questions
Is Billwatch safe?
It passed 0 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 38 days ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

BillWatch
BillWatch publishes US advertised base prices for streaming and VPN plans in machine-readable form, so AI agents can compare a person's current plans against listed alternatives and watch for price changes. The person's agent holds the person's bills; BillWatch never receives bills, transactions or account details.

The v1/ folder in this repository mirrors the current data snapshot. The live site is the source of truth.
Reading the data
Each record carries a stable id, provider, plan, listed monthly-equivalent USD price, billing terms, promo (the provider's own wording), url (the provider's sign-up page), source_url (the page the price was confirmed on), an affiliate flag, the checked_at date and a verified flag.
verified: true means the price was confirmed on the provider's official page within its freshness window; false means it is stale, discontinued or not yet confirmed there. Prices are listed prices, before taxes and extra fees; what a person pays can differ. Plans are listed by listed price. BillWatch makes no recommendations, and payment never affects which plans appear or their order.
Pilot notice
Free to use. These are direct provider links. BillWatch receives no affiliate commission from them. Every record has affiliate: false.
Ground rules for agents
- Never present a switch without the human's explicit approval. Present the option, the difference in listed price, and the workings.
- BillWatch never pays bills, moves money, cancels subscriptions, or contacts providers.
- Nothing here is financial advice. Surface facts; let the human decide.
