Use personal finance calculators with VS Code

Budgets, retirement projections and rent-vs-buy, computed the same way every time. Connect VS Code to the WingMan MCP gateway once and these tools are available in every conversation.

1. Connect VS Code

Create .vscode/mcp.json in your workspace (or run MCP: Open User Configuration for all workspaces), then start the server from the Chat view's tools picker.

{
  "servers": {
    "wingman": {
      "type": "http",
      "url": "https://wingmanprotocol.com/mcp",
      "headers": {
        "X-Wingman-Tools": "full"
      }
    }
  }
}

2. The tools you get

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.

3. Ask for it

Give VS 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.
