claude mcp add --transport http cinderfi-retirement-planning https://mcp.cinderfi.com/mcpWhat Cinderfi — Retirement Planning does
Cinderfi calculates retirement projections for individuals and couples, estimates taxes across Canadian provinces and US states, and helps compare benefit start dates for CPP/OAS and Social Security. Its tools also cover GIS eligibility, RRSP meltdown and Roth conversion strategies, withdrawal order, historical backtesting, and Monte Carlo simulations. Pro is required for couple calculations, Monte Carlo, the optimizer, and backtesting.
Connect the MCP server to Claude Code, Codex, Cursor, GitHub Copilot, or another supported client. Authentication requires an API key; in Claude Code, set it as CINDERFI_MCP_KEY. Without that credential, the server cannot authenticate. The free plan allows five calls per day and includes single-person tools, while several advanced tools are reserved for Pro.
