SECCI MCP server: EU consumer credit tools for AI agents

SECCI.pro runs a public Model Context Protocol (MCP) server so AI agents can compute a compliant APRC (TAEG), price an overdraft, and produce a pre-filled Standard European Consumer Credit Information (SECCI) form link. It works with Claude Desktop, Claude Code, ChatGPT connectors, Cursor, Windsurf, VS Code Copilot agent mode and any other MCP client.

Tools

• compute_aprc — APRC / TAEG for fixed-sum credit (personal loans, car finance / PCP with balloon). Accepts either a nominal interest rate or a monthly payment, plus upfront and monthly fees. Returns the APRC, the full instalment schedule, total amount payable, total cost of credit, the directive assumptions applied and the engine version.
• compute_overdraft_aprc — APRC for overdrafts and other open-ended credit, applying the drawn-in-full, repaid-over-three-months assumption of Directive (EU) 2023/2225 Annex III and Directive 2008/48/EC Annex I part II.
• build_secci_url — a link that opens the SECCI generator pre-filled, in any of the ten supported languages (en, fi, sv, de, fr, es, it, pl, no, da), so a human reviews the disclosure before it is issued.

Calculations are informational; the lender remains responsible for the disclosure it issues. See the verified test vectors, the REST API documentation and licensing.
