Pennylane MCP connector

The Pennylane connector brings your invoices, journals, ledger accounts and ledger entries into Claude, ChatGPT, Cursor and other AI clients through Elaichi, so each person can look up, book and reconcile entries inside their own Pennylane access.

  • How it connects. Connects with an API key. The credential goes into a vault nobody reads back.

  • One address. https://api.elaichi.ai/mcp, the same for every user.

  • Their own access. An agent never gets more than the person it acts for.

How to connect

  1. Open Connections, choose Add connection, and pick Pennylane.

  2. Optionally set Share with to give a team access, then press Connect.

  3. Paste a Pennylane API key. One person generates a token in Pennylane and pastes it once. Everyone else works through Share with, and never sees it.

Use cases

What teams do with Pennylane through Elaichi

Every one of these runs inside the access the person already has, and lands in the same audit log.

  • Accounting

    Book a journal entry from a plain request

    Describe the transaction, the journal and the account, and the entry lines are created in Pennylane with the supporting document attached to the ledger.

  • Accounting

    Match payments to the invoices they settle

    Ask for the open lines on a customer account and letter the payment against the right invoice lines in Pennylane, or undo a matching that was made in error.

  • Finance

    Import a batch of customer invoices

    Hand over the invoices from your billing tool and have them imported into Pennylane in one pass instead of keying each one by hand.

  • Accounts payable

    Bring received e-invoices into the books

    Import the electronic invoices your suppliers send so they land in Pennylane ready for review, coding and payment.

  • Bookkeeping

    Recategorize ledger lines before month end

    Pull the ledger entry lines still sitting in the wrong category, check them one by one, and move each to the right category in Pennylane before the close.

  • Finance operations

    Get told when the ledger changes

    Set up and manage Pennylane webhook subscriptions so your other systems hear about new entries as they happen, and review or remove those subscriptions when they are no longer needed.

Try asking

  • “Show ledger entries posted to account 401 last month.”
  • “Which journals have no entries this quarter?”
  • “List ledger accounts created since April with their attachments.”

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 my team share one Pennylane connection?

Yes. One person connects Pennylane in Elaichi and shares the connection with a team, and nobody else ever handles the API key. Each teammate still signs in to Elaichi as themselves, so the audit log records who booked which entry or lettered which payment in Pennylane.

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.
