}Use your Steady account from Claude, Cursor, or any MCP client. Read your publication's member counts, income, plans, subscriptions and newsletter subscribers. Hosted, no local install: connect with your own credentials.
Live endpoint: https://steady.usefulapi.io/mcp · Homepage: https://usefulapi.io
https://steady.usefulapi.io/mcp.claude mcp add --transport http steady https://steady.usefulapi.io/mcp, then run /mcp to log in.Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your Steady credentials.
Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/steady/
On first connect you provide your Steady API key (found in the publication's API integration settings in the Steady backend). The server validates it and stores it per user. No keys go in config files.
read tools are read-only; write tools mutate data (clients should confirm them); meta tools report usage, manage your subscription or send a feature request.
*Pro has a fair use limit of 10,000 tool calls a month on this server. For more, write to [email protected].
Pro covers this server only. Subscribe with steady_upgrade (it returns a Stripe Checkout link). Cancel any time with steady_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running steady_upgrade before then undoes the cancel. Or write to [email protected].
