DataFast is a web analytics platform that helps teams track website traffic, goals, funnels, visitors, and revenue attribution. It also supports payment-provider integrations so users can connect business metrics like subscriptions, MRR, LTV, and churn to acquisition sources.
DataFast exposes a REST API at `https://datafa.st/api/v1/`, a Streamable HTTP MCP server at `https://datafa.st/api/mcp`, and an npm-installed `datafast` CLI; auth is via `df_` website keys, `dft_` account tokens, and MCP OAuth for the MCP surface.

Create a website-scoped API key in Website settings → Developer. It creates a df_ key for one website. As a terminal alternative, run datafast websites apikeys create <websiteId> --name "Prod key" after authenticating the CLI. The raw key is shown once, so store it securely.
Create an account token in Account settings → API / MCP. Choose the website scope and only the permissions you need, then create and copy the dft_ token; it is shown once. The easiest CLI-assisted path is to run datafast login, which opens this page and prompts you to create/paste a token. You can also mint one from the CLI later with datafast tokens create once already authenticated.
Point your MCP client at the server URL and approve access in the browser. The server accepts a Client ID Metadata Document (CIMD), so the client authenticates with its own hosted URL as the client_id — nothing to register.
