What you can do with this MCP connector

Your AI agent reads your whole Sellsy CRM, period. You don't gotta click through a dozen dashboards to get answers. Your AI client connects directly to Sellsy's read-only API. It lets you audit every part of your sales and billing process—from figuring out who these people are to checking the cash flow on old invoices.

Forget clicking; just ask, and it pulls all that data for you.

Getting Your Head Around Prospects and Accounts

When you need to find someone or a company, you don't start from scratch. You use search_companies to narrow down your results fast using a keyword or a name. Once you spot the right place, get_company pulls all the deep-dive info on that whole client or prospect organization. If you need to know who works there, list_contacts generates a complete list of every single person stored in the system; then, for any individual contact, get_contact gives you all their specific details.

If you just want a quick look at everything recorded, list_companies provides you with a full roster of every company in your CRM's database. This setup means that whether you're tracking an old account or hunting for a brand new lead, your agent can pinpoint the right information instantly. It’s like having a super-powered research assistant who never gets tired.

Auditing the Sales Pipeline

Want to see where all the money is supposed to come from? Start with list_deals. This tool spits out an overview of every single open opportunity in your sales pipeline so you can immediately grasp the big picture. If that list shows a deal you need more info on, you just hand over the specific details using get_deal.

That pulls all data points for one particular sales deal—you see exactly how much it's worth and what stage it's currently sitting in. You can audit your entire pipeline this way: check the overview with list_deals, then drill down into any single opportunity with get_deal.

Tracking Cash Flow and Billing Health

Billing shouldn't be a headache. To track how healthy your finances are, you first call list_invoices. This gives you an overview of everything: drafts, what's been sent, paid invoices, and all the overdue junk. If one invoice looks sketchy or you need to verify details on a specific payment, running get_invoice pulls every single detail for that document—the full amount due, the exact date it was supposed to be paid by, and its current status.

You can also see what quotes you've been sending out; list_estimates shows you all the estimates sent to clients, and if you need the details on just one, you use get_invoice for that full financial picture.

Going Deep: History, Inventory, and Activity

You need context. You gotta know what happened before a deal got this far. To compile historical activity reports, list_activities automatically gathers chronological records of calls, meetings, or any tasks that've been logged against an account over time. It gives you the full story. For product stuff—like if you wanna check your catalog or see how much inventory is available for a deal—you use list_items to get a list of every single product and service in your catalog.

If you need to compile quotes, list_estimates shows all those documents. You can also pull specific client data using get_company to nail down the company details or get_contact for individual people's files.

It’s simple: list everything with a 'list' command to get an overview, then use the corresponding 'get' tool if you need the granular, deep-dive specifics on one piece of data. Your agent handles it all in one chat window.

How Sellsy MCP Works

  1. 1 Subscribe to this Sellsy integration server on Vinkius.
  2. 2 Configure your specific Sellsy V2 API Access token within your agent's settings.
  3. 3 Ask your AI client (Claude, Cursor, etc.) to cross-reference data, referencing the specific tools you need.

The bottom line is that your agent acts as a single pane of glass for all your Sellsy data without needing manual logins or report generation.

Who Is Sellsy MCP For?

Sales Managers, Account Executives, and Finance Ops teams. You're the person who gets stuck clicking through five different dashboards just to compile a status update for leadership. This server lets you pull that data—deals, invoices, and contacts—with one prompt.

Sales Manager

Needs to instantly list all deals in the pipeline or check which accounts have had zero activity this week without opening native reports.

Account Executive (AE)

Must review a client's entire history—contact details, past meetings, and current outstanding invoices—right before an important call.

Finance/Billing Specialist

Needs to compile a comprehensive list of all overdue or draft invoices across the company for immediate collection follow-up.

What Changes When You Connect

  • See your entire pipeline status with list_deals. Instead of opening the dashboard to find open opportunities, you just ask for it, and the agent pulls all active deal IDs and their projected value.
  • Know exactly where your cash flow stands using list_invoices. You can get a summary count of 'PAID' vs. 'OVERDUE' invoices in seconds, without running a formal report.
  • Never forget client history again. Combining search_companies and get_contact lets you pull up an account sponsor’s full profile right before a meeting, including their last call date.
  • Automate reporting with list_activities. Instead of manually compiling the week's calls and tasks into a spreadsheet for your manager, prompt the agent to dump the feed directly.
  • Get immediate product context using list_items or review pricing options by checking all sent quotes via list_estimates. This keeps you grounded in current catalog data.

Real-World Use Cases

01

The End-of-Week Status Report

A sales manager needs a list of all deals that haven't moved stage in 30 days. Instead of filtering the native CRM dashboard by date and then exporting, they tell their agent to run list_deals and filter the output for 'stale opportunities.' The agent provides a clean table with the deal ID and current status.

02

The Urgent Pre-Call Prep

An AE is about to jump on a Zoom call with 'Company Beta'. They don't want to spend five minutes digging through email folders. They ask their agent to search_companies for Beta, then run get_contact for the main decision maker. The result gives them the contact's title, last interaction date, and key company identifiers instantly.

03

The Cash Flow Triage

A finance specialist needs to know which clients owe money right now. They prompt their agent with 'show all overdue invoices.' The agent runs list_invoices, filtering only for the 'OVERDUE' status and providing a total dollar amount needed, avoiding manual reconciliation.

04

The Product Audit

An operations team member is building a new quote template and needs to ensure they have the most current product codes. They ask their agent to run list_items. The agent returns the full, up-to-date catalog data structured for immediate use in documentation.

The Tradeoffs

Listing vs. Searching

Asking 'Give me all contacts' when you really only care about one person at a specific company.

Don't use list_contacts if you know the name or ID. First, run search_companies(query: 'Target Corp'), then use that company ID to narrow your search with get_contact for the right individual.

General Status Checks

Asking a vague question like 'How's the money looking?' which yields too much unformatted data.

Be specific. If you need billing status, run list_invoices and specify: 'Filter results for OVERDUE status.' This directs the agent to the correct tool and filters the output.

Ignoring Deal Details

Calling list_deals but then forgetting which deal ID corresponds to the biggest potential revenue.

After running list_deals, immediately follow up by asking: 'Now, run get_deal for the top three opportunities.' This ensures you get granular data on the most important accounts.

When It Fits, When It Doesn't

Use this server if your primary need is data aggregation or auditing. If you want to know what happened, how much money is owed, or who was contacted, this toolset is perfect. It reads and compiles data from multiple sources into one view.

Don't use this if you need to write anything. This server offers read-only access. You cannot mark a deal as 'Won,' change an invoice status, or add a new contact record. For those actions, you must go back to the native Sellsy platform. If your goal is merely to summarize existing data for reports or decision-making, then this MCP Server is exactly what you need.

Works with Claude, ChatGPT, Cursor, and more

The Model Context Protocol standardizes how applications expose capabilities to LLMs. Instead of operating in isolation, your AI gains direct access to external platforms, live data, and real-world actions through secure, standardized connections.

This server provides 12 capabilities that interface natively with Claude, ChatGPT, Cursor, and any MCP client. No middleware. No custom integration required.

Available Capabilities

get_company get_contact get_deal get_invoice list_activities list_companies list_contacts list_deals list_estimates list_invoices list_items search_companies

Sifting through deal pipelines shouldn't take 15 minutes of dashboard clicking.

Today, checking the status of a major deal requires jumping between five different tabs: Opportunities, Contacts, Activities, Quotes, and Invoices. You copy IDs here, paste them there, cross-reference dates, and then export everything into Excel just to get one overview.

With this MCP Server, you prompt your agent once. You ask it to compile a status report across deals and invoices. The agent runs `list_deals` and `list_invoices`, compiling the necessary data points—deal ID, stage, monetary value, and payment status—into a single, clean text output.

Using list_invoices gives you cash flow visibility instantly.

Manually running reports in Sellsy to find all overdue invoices is tedious. You have to set date ranges, filter by status, and then manually check the amounts for every single record just to see which payments are stalled.

Now, you prompt the agent with 'Show me all critical unpaid items.' The agent runs `list_invoices`, providing a filtered list that immediately highlights the overdue records and gives you a calculated total of money owed. It’s fast.

Common Questions About Sellsy MCP

How do I find out what products are available using list_items? +

Running list_items returns every product ID, name, and service type in your catalog. This is useful for ensuring any quotes you pull or manually generate use current pricing information.

What's the difference between list_deals and get_deal? +

Use list_deals when you want a broad overview—a summary of all open opportunities. Use get_deal when you already know the specific deal ID and need every single detail about that one account.

Can I use search_companies to find contacts? +

No, not directly. You must first run search_companies to get the company ID, and then pass that company context to get_contact or list_contacts to pull related people.

How do I check if an invoice was paid? +

Run list_invoices. The output data structure includes a 'status' field; you can filter the results directly in your prompt for 'PAID' or 'OVERDUE'.

Does list_activities show everything that happened? +

list_activities compiles recent, key interactions like meetings, calls, and tasks. It gives you a chronological summary of client engagement without dumping every single email thread.

After I use `get_company`, how do I get a list of all associated contacts? +

You must pass the returned company ID to the list_contacts tool. This ensures you only pull people directly linked to that specific organization, filtering out general system entries.

If an invoice has been paid but I use `get_invoice`, will it show a zero balance? +

Yes; the tool returns a detailed record of all transactions. If payment cleared successfully, the 'PAID' status flag and corresponding transaction dates will be visible.

When running bulk checks with `list_deals`, should I worry about rate limits? +

Yes, the server enforces standard API rate limits per minute. For large data pulls (more than 50 records), you'll need to build a backoff or pagination routine into your agent.

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).
