An MCP server for your subscriptions and renewals
LemSubs runs a hosted MCP server. Add it to Claude, ChatGPT or Cursor, sign in once, and your assistant can read what you pay for, when it renews and what nobody uses. There is no bank login and no file to export each time you ask something.

What you can ask once it is connected
- What do I pay every month, and which line is the biggest?
- Which paid tools has nobody opened in 90 days?
- What renews in the next two weeks, and what will it cost?
- Which refund windows close this month?
How to connect each client
Claude signs in through your browser, so there is no key to paste. Cursor and the OpenAI Responses API use a key you create in Settings. Step-by-step guides live in the help centre.
How access is kept safe
You choose the permissions on the approval screen, reads and writes are separate, keys can be revoked at any time, and every call is written to your audit log.
