Perplexity

Automate multi-step invoice processing

Connect `list_sales_invoices` to your agent's reasoning chain. Your agent pulls raw invoice data and pipes it directly into downstream analysis tasks without manual intervention. This MCP Server lets you link specific outputs to follow-up actions. You define the logic flow where the agent executes a sequence of operations based on the data it receives from the Evoliz API.

Monitor CRM client health

Use `list_crm_clients` to fetch your database and pass results to `get_client_detailed_profile`. Your agent processes client history to flag accounts that require immediate attention. LangChain handles the tool selection dynamically. The agent decides when to pull deeper financial profiles based on the initial client list it generates.

Audit financial volume

Run `quick_financial_volume_audit` to get instant snapshots of your business standing. Your agent calculates outstanding balances and compares them against your current sales quotes. This data serves as the input for your agent's decision-making process. You get a clear picture of liquidity without digging through static reports.

Prerequisites

Python 3.10+ installed
langchain-mcp-adapters + langgraph packages
Active Vinkius subscription with a valid endpoint token

4

Run with any LLM
Swap ChatOpenAI for ChatAnthropic, ChatGoogleGenerativeAI, or any LangChain-compatible model. The MCP tools work identically across all providers.
