Perplexity

Knowledge-augmented accounting in LlamaIndex

Feed the output of `get_invoice` and `get_credit_note` directly into your vector store. Your index becomes a searchable archive of every financial document you have processed. This turns static records into a queryable knowledge base. You can ask your agent about specific payment trends or historical costs without browsing the dashboard.

Semantic search for financial documents

Your LlamaIndex pipeline uses `list_quotations` and `list_delivery_notes` to build a unified view of your sales pipeline. The agent retrieves context based on your natural language questions. Stop searching for files manually. Your agent finds the exact document details by querying the index you populated with MCP tool outputs.

Connect LlamaIndex to your MCP Server

Use the tool specification to integrate the server easily. Your agent calls `list_vouchers` to ground its answers in live, verified accounting data. This prevents the agent from hallucinating figures. It relies on the actual API response to answer your questions about tax categories or posting accounts.
