FinSync MCP connector

MCP URL: https://api.finsync.ar/mcp Spanish product guide: Asistentes de IA. FinSync is a back-office ledger — a structured spreadsheet for financieras. It records operations and balances. It never moves funds, connects to banks, or executes payments. Draft-creating tools do not change the ledger; confirm_write is the actual write.

​
Requirements

  • A FinSync company with mcp_enabled (admin / superadmin).
  • A FinSync user who can sign in and consent. The token is bound to that user and one company, with the same RBAC and assigned clients as Twin.

​
Connect

Revoke connections in the FinSync dashboard under Asistentes de IA, or disconnect the connector in the assistant.

​
Tools

Same names and behavior as Twin. Write tools that only create drafts are annotated readOnlyHint: false and destructiveHint: false. confirm_write is destructiveHint: true. Read: query_books, search_client_balance, lookup_operation, lookup_cheque, list/export/catalog tools, cheque-quote calculation, CUIT/bank public lookups, docs search, scan. Draft write: operation_{slug}, prepare_cheque_quote_pending, discard_operation_draft. Ledger write: confirm_write (confirm or discard the draft).

​
Rate limits and audit

  • 900 authenticated /mcp requests / 60s per token+employee; 720 / 60s per company+employee.
  • Each tool call is stored in McpToolCall (who, company, OAuth client, tool name, error flag, time). Arguments and response bodies are not stored.
