Budgets, retirement projections and rent-vs-buy, computed the same way every time. Connect Claude Code to the WingMan MCP gateway once and these tools are available in every conversation.
Run this once in your terminal. Then type /mcp inside Claude Code to confirm the server is connected.

Names and descriptions come straight from the live tool registry.
budgetAllocate monthly income across needs/wants/savings (50/30/20) and find your surplus or deficit and savings rate.retirementProject your balance at retirement, or solve the monthly contribution needed to hit a target.fire_numberFinancial-independence target from annual expenses and a safe withdrawal rate, plus lean/fat variants and years to reach it.rent_vs_buyCompare the N-year net cost of buying (mortgage, tax, upkeep, minus equity) vs renting, and find the breakeven year.savings_goalMonths to reach a savings target at a given monthly amount, or the monthly amount needed for a fixed horizon.These tools sit outside the default tool list, so the config above sets X-Wingman-Tools: full to load the whole catalogue. Without it, your agent can still reach them with discover_tools, then get_tool_schema, then tools/call.
Give Claude Code a task that needs it, for example “use budget from wingman”. The tool call goes to https://wingmanprotocol.com/mcp and the result comes back into the conversation.
