Give your AI assistants controlled access to TOConline sales documents, customers, and PDFs. No copying credentials into MCP clients and no write permissions.
Updated June 19, 2026
What is TOConline MCP?
A TOConline MCP server exposes selected invoicing data to an MCP-compatible AI application. InvoiceSync hosts that server, applies OAuth, and limits each assistant to documents, customers, account status, and PDFs for approved companies.
What you can ask the assistant
Read-only by design
The assistant can query sales documents, customers, account status, and PDF links. It does not create, finalize, or change fiscal documents.
Per-client-company grants
Share only the companies the assistant should see. New companies are not shared automatically.
Credentials encrypted in InvoiceSync
TOConline credentials stay stored in InvoiceSync and are never copied into Claude, ChatGPT, Cursor, or another MCP client.
Access model
- OAuth instead of API keys inside the AI client
- Provider credentials encrypted in InvoiceSync
- Per-client-company grants
- Read-only access, with no fiscal document creation
