Once connected, your AI tool can call any of these tools. You do not need to invoke them manually — the client discovers them and chooses the right tool based on your questions. Tools read from Finta storage (requires Storage Mode). High-volume tools support filters and pagination via cursor parameters in the tool schema. Most tools are read-only; a small set of write tools let your assistant categorize transactions and manage your spending categories. Finta MCP never moves money, opens or closes accounts, or changes your bank connections or destinations.

Write tools

These tools change your data in Finta. They are limited to categorizing transactions and managing the categories you’ve created — nothing financial.
ToolWhat it doesExample prompt
update_transactionSets or clears the category on a transaction”Categorize that Amazon charge as Office Supplies”
batch_update_transactionsUpdates many transactions at once (up to 250)“Categorize all my Starbucks transactions as Coffee”
create_categoryCreates a new manual category”Add a category called Software Subscriptions”
update_categoryRenames or edits a manual category”Rename my Misc category to Uncategorized”
delete_categoryDeletes a manual category”Delete the Test category”
batch_update_categoriesUpdates many manual categories at once (up to 250)“Group all my software categories together”
Write tools only affect manual (Finta-created) categories and the category assigned to a transaction. Categories synced from your bank or payment provider can’t be edited.
