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.

  • How it connects. App credentials. 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

In Elaichi

Connect Sellsy once

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

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

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 my team share one Sellsy connection?

Yes. One person connects Sellsy in Elaichi and shares the connection with a team, and nobody else ever handles the Sellsy API key. Each teammate still signs in to Elaichi as themselves, so the audit log names the actual person behind every change to a Sellsy company or contact.

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.

Does the Sellsy MCP connector work with Gemini, Codex, Claude Code or other MCP clients?

Yes. Sellsy is reached over the same MCP endpoint every client uses, so anything that speaks MCP can call it — Gemini, Codex, Claude Code, Windsurf, Cline, Zed and OpenCode among them — alongside Claude, ChatGPT, Cursor, and the Elaichi Agent. The tools on offer and the access behind them are identical whichever client asks. Only the setup screen differs.

Is Elaichi an alternative to Zapier MCP for Sellsy?

Yes. Both let Claude, ChatGPT or Cursor use Sellsy. Zapier MCP fits a team that already automates in Zapier, since each person signs in and acts as themselves in that account. Elaichi fits when IT wants one address for the whole company, per-tool rules by role, and a record of every Sellsy call.

How is Elaichi different from Composio for Sellsy?

Composio gives AI agents tools and sign-in handling across 1,000+ apps, for developers building agents or people using an assistant, billed per tool call. Elaichi gives a company's own people governed access to Sellsy: one address, restrictions per role or user, and $15 per user per month. Both have role permissions and a log of every call.
