Read publication income, plans and subscriptions; list newsletter subscribers in Steady.
The publisher's own server: Ably MCP by usefulapi
Read-only access to a Steady publication's member counts, income, membership plans, subscriptions and newsletter subscribers.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/io.usefulapi%2Fsteady/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Add this to your client's mcpServers config.

}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].
