KontoCSV

Connector for Langdock

The KontoCSV remote MCP connector lets Langdock users inspect bank statements and transaction CSVs, prepare accounting conversions, use existing KontoCSV credits after explicit confirmation, track conversion status, and download validated accounting exports.

Connection endpoint

Remote MCP URL: https://www.kontocsv.de/api/mcp/langdock

Transport: Streamable HTTP. Authentication uses OAuth 2.0 authorization code flow with PKCE and Dynamic Client Registration. Each Langdock user connects their own KontoCSV account.

Connect in Langdock

  1. Open Integrations in your Langdock workspace settings.
  2. Choose Add integration, then start from scratch and connect a remote MCP server.
  3. Enter https://www.kontocsv.de/api/mcp/langdock as the server URL.
  4. Select OAuth 2.0 with Dynamic Client Registration.
  5. Create and connect the integration, then sign in to KontoCSV and approve access.
  6. List server features and enable the eight KontoCSV accounting actions.
  7. Save the plugin. If Langdock asks for an MCP connection in chat, select your KontoCSV connection and optionally make it the default.
  8. Use the confirmation in the conversation after the credit quote. A separate host-side confirmation prompt on the conversion action is not required and can cause duplicate approval prompts.

Prerequisites

  • A KontoCSV account.
  • Existing KontoCSV credits for paid conversions. Inspection and preparation do not spend credits.
  • A supported PDF bank, card, or payment statement, or a transaction CSV on the user's local device.

How file handoff works

  1. Ask Langdock to use KontoCSV for the desired accounting task.
  2. KontoCSV creates a short-lived browser-upload link.
  3. Open the KontoCSV link and choose the source file on your device. The browser uploads it directly to KontoCSV private storage.
  4. Return to Langdock after the upload is complete.
  5. KontoCSV verifies the uploaded object and can inspect the document before any paid conversion begins.
  6. A conversion starts only after the required existing credits are shown and the user explicitly confirms the conversion.
KontoCSV does not need Langdock chat history or unrelated workspace content. Source documents are selected by the user through the direct KontoCSV browser-upload flow.

Available tools

  • Create browser upload: creates a short-lived user-bound upload link.
  • Complete browser upload: verifies the direct upload and returns a source reference.
  • Inspect: identifies document type, page scope, currency, balances, and compatible export profiles.
  • Prepare conversion: checks required and available existing credits without checkout.
  • Credit balance: reads total, reserved, and available KontoCSV credits.
  • Convert: starts a prepared conversion after explicit user confirmation.
  • Status: tracks processing and validation state.
  • Download: returns a short-lived link for an eligible completed export.

Example requests

Inspect my bank statement with KontoCSV and tell me which accounting export formats are available. Do not convert it.
Convert my bank statement to DATEV SKR04 using my existing KontoCSV credits. Give me the KontoCSV browser upload link first and do not start until I confirm.
Convert my transaction CSV to Exact Online using my existing KontoCSV credits.

Supported accounting formats and safeguards

Depending on the source document, KontoCSV supports Standard Bank CSV, DATEV SKR03/SKR04, Lexware, MT940, CAMT.053, QuickBooks/QBO, Xero, Exact Online and further locale-specific formats. Formats requiring verified opening and closing balances are available only when the statement provides sufficient balance evidence. Files that fail quality controls must not be imported as validated exports.

Reviewer test files

Langdock reviewers may use these synthetic fixtures without uploading real customer financial information:

Download the fixture first, then select the saved file on the secure KontoCSV browser-upload page. Inspection is free. A conversion requires existing KontoCSV credits and an explicit approval. KontoCSV does not ask for bank-login credentials or initiate payments through this connector.

Troubleshooting

  • If the upload link has expired, ask the plugin to create a new short-lived link.
  • If upload verification succeeded but a later inspection fails, retry with the existing uploaded source; do not re-upload unless the source is missing or expired.
  • If the quote expires, prepare a new quote for the existing source and confirm it before starting the conversion.
  • If credits are insufficient, manage credits directly in the KontoCSV account; no checkout or purchase tool is exposed through Langdock.

Privacy, retention, and support

See the Langdock connector privacy notice and the full KontoCSV Privacy Policy. Uploaded and generated conversion files are automatically deleted no later than 7 days after upload or creation.
