Sellsy MCP connector
The Sellsy connector brings companies, contacts, comments, addresses and payments into Claude, ChatGPT, Cursor and the Elaichi Agent, so each person can read and update Sellsy records inside their own access, with every call logged.

FAQ
Frequently asked questions
How do I connect Sellsy to Claude?
Connect Sellsy in Elaichi first, which means pasting the API key from your Sellsy account, since there is no OAuth application to register and no client ID or secret to generate. Then in Claude open Customize, then Connectors, then Add, and paste https://api.elaichi.ai/mcp. Sign in with your Elaichi account and Sellsy companies, contacts and comments are available in Claude.
Does Sellsy work with ChatGPT and Cursor as well as Claude?
Yes. Sellsy is connected once in Elaichi and the same endpoint, https://api.elaichi.ai/mcp, is pasted into Claude, ChatGPT, Cursor, any other MCP client and the Elaichi Agent. There is nothing to set up again per client.
What can an AI agent actually do with my Sellsy data?
An agent can look up Sellsy companies and their contacts, add or edit comments after a call, correct an address, record a payment, convert a prospect into a client and pull an export of companies. Because Sellsy has hundreds of actions, the agent searches for the right one as you ask, so short concrete asks like "add a comment to Acme about today's call" work better than long paragraphs.
Does connecting Sellsy give the AI access to everything in my Sellsy account?
No. Every call to Sellsy runs as the person who signed in, so the agent sees the companies, contacts and payments that person can already see in Sellsy, and nothing more. Elaichi can narrow that further with roles and restrictions, but it can never widen access beyond what Sellsy itself grants.
Can I stop an agent from deleting or changing things in Sellsy?
Yes. Restrictions in Elaichi apply per action, so you can allow reading Sellsy companies and adding comments while blocking deletes or edits to addresses. A blocked action is never advertised to Claude, ChatGPT or any other client, so no prompt can reach it.
What happens to a Sellsy connection when someone leaves the company?
Offboarding that person in Elaichi ends their access to Sellsy at once, across every client they used. A shared Sellsy connection keeps working for everyone else on the team. If you disconnect Sellsy in Elaichi, it disappears from Claude, ChatGPT, Cursor and the Elaichi Agent in one step.
