https://tillbooks.ch/en/blog/ Explainers on Swiss banking formats, agent-native accounting over MCP, and keeping Swiss books, from the team building TILL, the open-source ERP. en https://tillbooks.ch/en/blog/ebics-explained/ https://tillbooks.ch/en/blog/ebics-explained/ Tue, 06 Oct 2026 08:00:00 GMT Swiss banking EBICS (Electronic Banking Internet Communication Standard) is a standardised internet protocol for exchanging files between a company and its bank, used in Germany, France, Switzerland and Austria. The company registers three key pairs, for authentication, signature and encryption, and in Switzerland confirms them with a signed letter. It can then download statements such as camt.053 and, with a signing key, upload payment orders. https://tillbooks.ch/en/blog/mcp-meets-the-ledger/ https://tillbooks.ch/en/blog/mcp-meets-the-ledger/ Mon, 28 Sep 2026 08:00:00 GMT Agents and MCP Yes, if the ledger enforces the rules rather than the agent. In TILL, an open-source Swiss ERP, an agent posts through the MCP verb post_entry. Every call carries an idempotency key, so a retry never double-counts. By default the write becomes a proposal a person approves. The engine refuses unbalanced entries and locked periods, and a posted entry is only ever reversed, never edited.
