## What fibuki does, in the publisher's words

Pre-accounting for Austrian one-person businesses, from inside an AI assistant: set up, import a bank CSV, find and match the invoices for a month, hand the Steuerberater clean data.

This is a skills-only plugin on top of FiBuKI's MCP server. There is no FiBuKI logic in it: FiBuKI reads the documents, scores the matches and stores everything; the skills drive the loop and ask the user once per batch. Plan and decisions: handoffs/2026-10-02-openai-plugin.md.

- Add FiBuKI's MCP server to ~/.codex/config.toml. No key needed: FiBuKI is an OAuth server, and Codex discovers it from the 401 challenge, registers itself and signs the user in.

toml [mcp_servers.fibuki] url = "https://fibuki.com/api/mcp/sse"

- Sign in: codex mcp login fibuki. A FiBuKI window opens; sign in or create an account (a new user is asked who they are first), then choose Allow. The connection shows up under Settings, Integrations as a connected app and can be revoked there.
