}Use your billey account from Claude, Cursor, or any MCP client. Read the clients, invoices, quotes, expenses, bank transactions and time entries of your book. Hosted, no local install: connect with your own credentials.
Live endpoint: https://billey.usefulapi.io/mcp · Homepage: https://usefulapi.io
https://billey.usefulapi.io/mcp.claude mcp add --transport http billey https://billey.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 billey credentials.
Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/billey/
On first connect you provide a billey personal access token (your book's Settings → API tokens; two-factor authentication must be on). 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 billey_upgrade (it returns a Stripe Checkout link). Cancel any time with billey_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running billey_upgrade before then undoes the cancel. Or write to [email protected].
