The time had come to renew my mortgage, while exploring different scenarios I found myself keeping asking Claude Code the same questions. "What's the base rate", "when's the next MPC meeting", "how has it moved over the last year" etc. Doing that by hand a few times made me wonder if an MCP server wouldn't be a good fit for this, so I built one. Partly to solve the actual problem and partly because I hadn't built an MCP server before and wanted to try it out.

It wraps the Bank of England's public (no auth or API key)IADB statistical database.

Tools for the current base rate, rate history/stats over any range, the next MPC meeting date, and generic access to any IADB series by code (SONIA, exchange rates, quoted mortgage rates).

Any feedback welcome!
