Xero MCP

An open-source MCP server that provides Xero Accounting read capabilities alongside a local SQLite ledger for aging, reconciliation, and GL tie-out. It allows agents to answer cross-client questions without rate-limit hits or per-tech SaaS fees, keeping data local unless explicitly routed elsewhere.
