FAQ
Frequently asked questions
How do I connect Pennylane to Claude?
First connect Pennylane in Elaichi by pasting the API key from your Pennylane account, then in Claude open Customize, then Connectors, then Add, and paste https://api.elaichi.ai/mcp as the endpoint. Pennylane connects with an API key, so there is no OAuth application to register and no client ID or secret to generate. You sign in to Elaichi with your own account, and from then on Claude reaches Pennylane through that one endpoint.
Does Pennylane work with ChatGPT and Cursor as well as Claude?
Yes. Once Pennylane is connected in Elaichi, the same endpoint, https://api.elaichi.ai/mcp, works in Claude, ChatGPT, Cursor, any other MCP client and the Elaichi Agent. You connect Pennylane once and every client you use picks it up.
What can an AI agent actually do with my Pennylane data?
An agent can list and read your Pennylane journals, ledger accounts and ledger entry lines, create new entries and attach supporting documents, letter payments against invoices, and update the category on a ledger line. It can import customer invoices and received e-invoices in bulk, and manage the webhook subscriptions that tell other systems when Pennylane changes. Because this connector covers a lot of ground, short concrete asks such as "show me the unmatched lines on account 411" work better than long paragraphs.
Does connecting Pennylane give the AI access to all of my company's books?
No. Every call to Pennylane runs inside the access of the person who signed in to Elaichi, so an agent sees the same journals, accounts and invoices that person could already see in Pennylane. Elaichi can narrow that further, for example to reading only, but it can never widen access beyond what Pennylane itself grants.
Can I stop an agent from deleting or changing things in Pennylane?
Yes. Restrictions in Elaichi apply per action, so you can allow reading Pennylane ledger entries while blocking the creation of entries, the removal of lettering or the deletion of webhook subscriptions. A blocked action is never advertised to Claude, ChatGPT, Cursor or any other client, so no prompt can reach it.
What happens to a Pennylane connection when someone leaves the company?
Offboarding that person in Elaichi ends their access to Pennylane through every AI client at once. If they had shared a Pennylane connection with a team, it keeps working for everyone else. If you want it gone entirely, disconnecting Pennylane once in Elaichi removes it from Claude, ChatGPT, Cursor and every other client at the same time.
