MCP tools available.

The local Warm MCP server makes these tools available to supported clients.

  • get_financial_context

    Read-only compact FinancialContext JSON. Includes status.position, status.accounts, transaction index total/months, recurring, budgets, goals, snapshots, liabilities, holdings, and health. The status.position field is a point-in-time (as-of-date) balance snapshot, separate from transaction and behavior windows. A null position means no position snapshot is available. Transaction items are not inline; use get_transactions for items. "Show my connected accounts and current balances"

  • get_transactions

    Read-only transactions from the FinancialContext artifact. Pass `period: "latest"` for the fixed 10-day latest window or `period: "YYYY-MM"` for a month page. The latest window is not caller-configurable. Months outside the covered range return an error. "What did I spend last month?"

  • search_operations

    Search the supported Warm operation catalog. Use this first to find the smallest matching operation. "What approved automation is available?"

  • describe_operation

    Describe one operation, including its input schema and risk. For write operations, pass the exact intended input to receive an approval with its ID, status, URL, and expiry. "Describe this approved operation"

  • invoke_operation

    Invoke one previously discovered Warm operation. Every write operation requires the approval_id returned for the exact same input by describe_operation. "Run this approved operation"
