Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Available tools 8

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

statement

statement_aging

Age open invoices into 0-30, 31-60, 61-90 and over 90 days past DUE date at a date, per client and currency, with the invoices themselves. Free. statements_report rolls up the whole book instead.

statement_build

Build one client's statement for a period: opening, invoices, payments with deposits applied broken out, credit notes and closing, formatted and in minor units. Free: 5 a month; a rebuild is free.

statement_pdf

Call this tool to render one client's A4 statement of account and return a download link valid for one hour. Titled STATEMENT OF ACCOUNT, movements in date order, BALANCE OUTSTANDING at the foot. Pro.

statement_text

Turn one client's statement into a plain-text letter for an email: movements in date order, opening and closing balances, deposit held, a sign-off. It is also a .txt download link valid one hour and counts toward the 5 a month; statement_pdf writes the A4 page.

license

license_activate

Turn Pro on for this connection with key, an MCPL1.<payload>.<signature> issued at checkout for this server or the bundle. Data under your token stays; a wrong or expired key changes nothing. license_status confirms it.

license_status

Report this endpoint's licence state for your token as JSON: the product, the tier free or pro, why it is not Pro, and the checkout URL. Call it to explain a free-tier refusal. No arguments, nothing changes.

dunning

dunning_text

Write a payment chaser at level 1 friendly, 2 firm or 3 final demand: every OVERDUE invoice with its age, the total and your bank details. Refused if nothing is overdue. No interest is stated. The letter is also a .txt download link valid one hour. Level 3 is Pro.

statements

statements_report

Receivables across every client at a date: totals and aging per currency, clients ranked by how much is OVERDUE, and the oldest overdue invoice. Pro. statement_aging is the free per-client view.

Dunning — questions

Answers built from our own checks of this server.

What can Dunning do?

It exposes 8 tools, read directly from the server on our last check. Among them: dunning_text, license_activate, license_status, statement_aging, statement_build, statement_pdf and 2 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

What is Dunning mostly used for?

Its tools cluster around statement and license. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is Dunning working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 88 of 88 checks got a reply (100.0%), average response time 195 ms. The bar chart above shows every period we have measured.

How do I connect Dunning?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Dunning need an API key?

No. Dunning completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 8 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Dunning?

It answers our handshake in 195 ms on average, which is faster than 74% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is Dunning open source?

The code is open source: it is published under the MIT licence, written in JavaScript and 2 stars on GitHub. The licence covers the code in the repository, not the hosted service at mcp.zovo.one, which runs on its operator's own terms.
