The Workbench checks inside your product. As an MCP server, no AI, nothing stored.

02The fifteen tools · as of 12 November 2026

Every tool answers with a readable findings text and with structured data (structuredContent) for your interface. Column names may be German or English. Three tools are new in the server as of today: the three checks of the document chain.

• check_price_increaseCheck a price increaseCompares a supplier's increase with the official producer price indices (Eurostat) for Germany and says how far it sits above the market.Input: category, month of the last agreed price, requested increase in percent, optional annual spend in euros.
• list_categoriesCategoriesReturns the categories check_price_increase knows, with their index codes.Helper, no input required.
• screen_sanctionsScreen sanctions listsScreens a supplier name against the EU, UN, US and UK sanctions lists.Input: name of the supplier or person.
• calculate_notice_deadlineCalculate a notice deadlineGives the last day a contract can still be terminated, from term, notice period and renewal.Input: start, term, notice period, renewal.
• check_discount_windowCheck the discount windowReads an open-items list and says which early-payment discounts expire in the next days, which are blocked by a hold or an open clarification, which are already lost and which payment run still catches them.Input: open items, optional clarifications, as-of date, window, payment-run weekdays.
• check_approval_matrixCheck the approval matrixLays the approval matrix over the people list: approvers who left, missing deputies, missing system roles, limit gaps and overlaps, plus the open approvals stuck with those people.Input: matrix, people list, optional open approvals, as-of date.
• check_invoice_paymentCheck a payment before releaseMatches an invoice's supplier to the vendor master (VAT ID, IBAN, name similarity), validates the IBAN checksum and flags a new or unknown bank account, a blocked or dormant vendor and a first payment. Verdict: stop, check or ok.Input: invoice header, vendor master.
• check_rasci_matrixCheck a RASCI matrixChecks a RASCI matrix against the people list: tasks without an A, several A, no R, roles without an active person.Input: tasks with codes per role, optionally the people list.
• check_catalogCheck a catalogPuts a supplier’s new price list next to the old one: increases per item, hidden changes in unit and content, new and dropped items, extra cost per year.Input: new price list, optionally the old list with annual quantities, threshold in percent.
• build_category_profileCategory profileBuilds a file per category from the spend list and, if present, the contract list: volume, suppliers, concentration, next notice date, levers.Input: spend rows, optionally contracts, optionally the category.
• find_in_listStatus answer from a listSearches a list, such as open items, open purchase orders or suppliers, for a document, order or supplier number, a name or a keyword and returns the matching rows. RE-01042 and 1042 are the same number.Input: search term and the list as rows or CSV text.
• analyse_spendSpend cubeAnalyses a spend or order export: who carries the volume, small orders, bundling, possible duplicate postings and the tail X-ray.Input: spend rows with supplier and amount, optionally date, category, order number; small order threshold.

Returns ready-made queries to the supplier and for internal clarification.Input: at least two documents as data (header and line items), optionally tolerances and the vendor master for payment protection.
• check_vendor_masterVendor master X-rayChecks a vendor master for duplicates, invalid IBAN and VAT ID, gaps, dormant vendors and risk signals such as one IBAN under two names. Returns a clean-up list with a proposal per record.Input: the master as rows or CSV text, up to 1,000 vendors per call; optionally similarity threshold and months without activity.
• build_business_caseBusiness Case BuilderTurns your own assumptions into bands for annual value, ROI and payback and shows where the value comes from: manual effort, rework, value leakage. Same formula as the ROI calculator on the website. Bands, not a promise.Input: spend and value leakage, or transactions, minutes and hourly cost; plus investment and scenario.

Plus eight tools for looking things up, also without AI and without sign-in: the library, the templates of the Execution Toolkit Library and the free excerpt of the Painpoint Atlas.

• find_painpointFind a pain pointTakes a situation in your own words and names up to three matching pain points.Input: the situation in one or two sentences.
• get_painpointRead a pain pointOne pain point with what happens, the number of findings, cause, lever, an anonymised example and the matching tool. For the 12 open pain points.Input: id, PP01 to PP49.

Live in Claude since 5 November 2026 with a Workbench licence: clause radar, offer comparison, invoice check, scope of work and meeting minutes (see In Claude). In preparation for vendors with a partner key: read a document, draft a reply letter, negotiation sparring.

03In Claude · connector with your Workbench licence · new on 5 November 2026

Add the server as a connector in Claude. The fifteen checks above work at once and without signing in. Five AI analyses, the negotiation sparring, the full Painpoint Atlas and your licence status need your AICTIONBOT™ Workbench licence: the first time Claude reaches one of them, it shows a Connect button, you paste your Workbench key once, and Claude continues the same request.

1. Add the connectorIn Claude, open Customize, then Connectors, and add a custom connector. Name: AICTIONBOT™ Werkbank. URL: https://www.kulicadvisory.com/mcp. Under authentication choose the option that signs in only when the server asks, and keep Claude’s published identity (CIMD) as OAuth client. No sign-in at this point.
2. Use the checksAsk for example: “Is a 9 % price increase on packaging since March 2024 justified?” or “Screen this supplier against the sanctions lists.” Claude calls the check without an account.
3. Connect your licence onceWhen you ask for a contract review or an offer comparison, Claude shows Connect. On our page you paste your Workbench key (Workbench, licence section, “Copy key”; it starts with KAW1). Without a key, choose “Connect without a licence” there and the fifteen checks stay available. A trial week can be started on the same page. You can disconnect at any time in Claude’s connector settings.

Your data: documents and questions are processed for the answer and not stored by KULIC Advisory. Stored are only the usage counter of your licence, as in the Workbench, and a one-way marker that a sign-in code or renewal token has been used, deleted after it expires. The key travels encrypted inside the access token Claude holds. Sign-in follows OAuth 2.1 with PKCE: no password, no payment data. Details in the privacy notice.

04Integrate · three steps

1. Add the serverIn Claude, ChatGPT, Cursor or your own agent, add the MCP server with this address. For clients with a configuration file:

   {
     "mcpServers": {
       "aictionbot-werkbank": {
         "url": "https://www.kulicadvisory.com/mcp"
       }
     }
   }

2. List the toolsA tools/list returns the fifteen tools with their full input schema:

   curl -s -X POST https://www.kulicadvisory.com/mcp \
     -H 'content-type: application/json' \
     -H 'accept: application/json, text/event-stream' \
     -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

3. Call a checkA tools/call with data from your system. Example discount window with one open item; the answer carries the findings text and structuredContent with KPIs, findings and payment runs:

   {"jsonrpc":"2.0","id":2,"method":"tools/call","params":{
     "name":"check_discount_window",
     "arguments":{
       "as_of":"2026-11-03","window_days":10,"language":"en",
       "open_items":[
         {"document":"INV-51077","supplier":"Example Electrical Ltd","invoice_date":"2026-10-28",
          "amount":15410.50,"discount_percent":2,"discount_days":14,"net_days":30,"blocked":"yes"}
       ]
     }
   }}

No SDK required. If you prefer to talk directly: JSON-RPC 2.0 over POST, answers as JSON. Errors come back as isError with plain text, never as an empty answer.

05Terms · public and partner

A test key for a 30-day pilot is free by mail. For comparison: a price-increase check costs the end customer €1.99 in the Workbench. A vendor who offers it to customers 2,000 times a month pays about 35 cents per check in the partner plan and has a feature that would otherwise take months to build.

06Rules · what the server does and does not do

1. Nothing is storedOpen items, matrices, invoice headers and master data are checked in memory and discarded with the answer. The only count kept is how often a tool was called, without content and without sender.
2. No AI in the checkFixed rules, checksums (IBAN), similarity measures and official indices (Eurostat). The same result for the same input, verifiable at any time.
3. Lean inputsPass only the columns the check needs. Names in the approval matrix can be replaced by initials; the result stays the same.
4. LimitsRate limit per sender, lists up to 2,000 rows (vendor master up to 20,000). Beyond that with a partner key.
5. Not legal or tax adviceFindings are practical checks from procurement, not legal counsel. The source line in every answer says so to your users as well.
