## Description
Look up how to cancel 8,600+ subscriptions: methods, mailing addresses, notice periods, letters.

## Tools
Capabilities this server exposes over MCP:

- **search_companies** — Find companies by name (for example "netflix" or "planet fitness") among the subscriptions and memberships Postbye has a cancellation guide for. Returns each match's slug, category, how the company takes cancellations and the guide URL. Use the slug with get_cancellation_guide.
- **get_cancellation_guide** — How to cancel one company's subscription or membership: how it takes cancellations, the notice period, the traps to check first, billing-partner notes, sources, when the facts were verified, the mailing address(es) on file and the guide and address page URLs. Accepts a company slug from search_companies (merged duplicate slugs resolve to the current one).
- **get_cancellation_letter** — A plain-text cancellation letter for one company, built from the same template as Postbye's free letter tool, plus where to send it. Fields not supplied stay as [bracketed placeholders] to fill in. Nothing is stored.
- **list_categories** — The category hubs of the cancellation guides (streaming, gyms, phone and internet, insurance and more) with the number of guides in each and the hub URL.

## Documentation

## What Postbye does

Postbye provides subscription-cancellation reference information through MCP. Its coverage includes more than 8,600 subscriptions and focuses on the practical details needed to submit a cancellation request.

An AI client can use Postbye to look up how a particular subscription should be cancelled, where cancellation notices should be sent, how much notice may be required, and whether a cancellation letter is available. These details help an agent turn a general request such as “cancel this subscription” into a more specific set of instructions.

The service is suited to research and preparation. It can help identify the relevant cancellation route and supporting information before a user contacts the subscription provider.

## Tools and capabilities

Postbye’s lookup capabilities cover four main types of information:

- Cancellation methods, such as the stated way to request cancellation.
- Mailing addresses for cancellation notices.
- Notice periods that may affect when a cancellation takes effect.
- Cancellation letters that can support the request.

The service is useful when the subscription’s cancellation process is unclear or when a user needs a formal notice prepared. Queries should identify the subscription being researched so the returned guidance can be matched to the correct service.

Postbye is an information lookup service rather than a replacement for the cancellation process itself. The returned method, address, notice period, or letter can guide the next step, but the user or another system must follow the applicable cancellation procedure.

Its narrow scope makes it a fit for agents that need subscription-cancellation research alongside other workflows. It is less suited to general finance operations or tasks unrelated to finding cancellation instructions.
