Is my Sellsy data safe with this MCP?

Yes. This MCP uses read-only access, meaning your agent can see your data to answer questions but cannot change, delete, or create any records in Sellsy.

Which AI clients can I use with Sellsy?

You can use this MCP with any compatible client, including Claude, Cursor, and Windsurf.

Do I need to host the MCP myself?

No. Vinkius hosts and manages the MCP for you. You simply connect your client and start working.

Can I use this to create new deals?

No. This specific MCP is designed for read-only access to audit and retrieve information like deals, invoices, and contacts.

What happens if I change my Sellsy API token?

You will need to update your credentials within the Vinkius dashboard to maintain the connection.

Can the AI alter invoices or update CRM statuses remotely?

No, it cannot. The agent is explicitly configured to possess pure Read-Only access capability via API V2 GET methodology endpoints (Such as list_companies and get_invoices). Your operational data remains completely immutable regardless of what you prompt.

Can I query a specific estimate document generated for a client?

Yes. While the integration allows sweeping over lists using list_estimates, the LLM can interpret the raw data to give you the summary of any pending quotes directly tied to associated internal pipelines effortlessly.

Does it track sales activities like recent calls?

Yes—by prompting your LLM with the underlying list_activities directive, you immediately gain access to the chronological logs outlining calls, meetings, generic events, and tasks created by your native Sales Development Representatives (SDRs).

Waiting for input…

Works with modern AI clients that support MCP, including ChatGPT, Claude, Cursor, and more.

Your AI does the work. We keep it safe and sound.

No other AI tool gives you this. Your workflow runs in the client you already love, your account stays protected, and you decide what the agent can and cannot do. It is the whole reason to make the switch.

Each Connector lives inside our infrastructure, the same place where your workflow runs. The three things below are already part of it, working quietly in the background so you never have to think about them. Nothing to add, nothing to set up, nothing to worry about.

V8 Isolate01

Each Connector runs inside its own sealed environment.

Each Connector runs inside its own sealed V8 runtime — no access to your files, your system, or other servers. A Connector never sees past its own request.

Kill Switch02

One switch stops every agent. Instantly.

One action deactivates every Connector, revokes every token, and ends every session at once. AI Governance keeps the record.

FinOps per User03

Spending limits that pause instead of surprise.

Every user keeps their own connections and credentials, isolated from everyone else. Anything that would cross your spending limit is held for your approval, not billed.

Three controls, built into the layer your AI connects through.

One connector, every AI

Sellsy CRM works with the most popular AI clients.

These are the most popular clients, each with a step-by-step guide: one link, set up once, with governance and visibility built in. And because everything runs on the MCP standard, the same connection also works in any other compatible client — nothing to rebuild.
