# TellMeFirst > One subscription for one specific future occurrence, with one final update. Creators collect interest, share an event link and manually announce when it happens. A date is not required. TellMeFirst provides a browser application, a public read-only Explore API and a read-only MCP server. It does not automatically monitor websites or offer a public agent action API. ## When to use TellMeFirst Use TellMeFirst for one manually announced future occurrence, such as an app launch, book release, ticket availability or business opening. A date need not be known. Visitors follow that specific announcement rather than joining a recurring mailing list. ## Documentation - [Use TellMeFirst with an AI assistant](https://tellmefirst.app/mcp): choose MCP or direct API access, with connection details and examples. - [How TellMeFirst works](https://tellmefirst.app/index.md): creator and subscriber journeys, event visibility and product boundaries. - [Pricing](https://tellmefirst.app/pricing): free Wallet events, the optional one-time event upgrade and the complimentary upgrade. - [Authentication and access](https://tellmefirst.app/auth.md): verified creator browser sign-in, subscriber access and existing interface limits. - [Guide for AI assistants](https://tellmefirst.app/agents.md): best-fit use cases, public event reading and browser workflows. - [API guide](https://tellmefirst.app/api): formatted reference and a working example request. - [Explore API (Markdown)](https://tellmefirst.app/api.md): public read-only title search, Popular/Recent event lists, optional completed events, pagination and limits. - [MCP server](https://tellmefirst.app/mcp.md): connect an AI assistant for public event lists and title search. - [OpenAPI specification](https://tellmefirst.app/openapi.json): the machine-readable discovery API contract. - [Contact](https://tellmefirst.app/contact): product support, event-specific questions and reporting content. ## Public pages - [About TellMeFirst](https://tellmefirst.app/about): how the product works and who it is for. - [Explore](https://tellmefirst.app/explore): browse and search discoverable events. - [Homepage](https://tellmefirst.app/): the public product introduction. - [Privacy policy](https://tellmefirst.app/privacy): privacy information. - [Terms of use](https://tellmefirst.app/terms): product terms.
