Overview

AI-generated overview

Remote MCP endpoint for Jahresabschluss.io that lets an AI assistant work with German company bookkeeping, VAT and tax preparation data.

What you can do
  • Connect an assistant to a German bookkeeping and tax service for companies.
  • Work with bookkeeping, VAT and tax preparation data through the provider's API.
  • No individual tools are documented in the listing, so the exact operations are not described here.
When to use it
Useful if your company keeps its bookkeeping and VAT records in Jahresabschluss.io and you want an assistant to help with German bookkeeping and tax preparation tasks through that account.
Requirements
A remote MCP endpoint at the provider's API host, reached over streamable HTTP. A company API key from the Jahresabschluss.io app (Settings, AI agent and API), sent as a bearer token in the Authorization header.
Before you install
The connection requires a company API key sent as a bearer token in the Authorization header; treat it as a secret and grant it only to assistants you trust. The listing names no tools, so what the assistant can read or change in your bookkeeping data is not documented; confirm this before connecting. Bookkeeping and tax data is sensitive financial information.

Installation

In SourceWeft

  1. Open Jahresabschluss.io – Buchhaltung & Steuern in the dashboard and add it to a workspace.
  2. Connect Authorization token credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.jahresabschluss%2Fbuchhaltung/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

This server asks for a credential such as an API key, so SourceWeft could not read its tools without one and has not indexed them.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
