Perplexity

Build agentic booking pipelines

Chain your logic by feeding outputs from `search_cars` directly into `get_car_details`. This MCP server lets your LangChain agent make decisions based on live pricing data instead of static guesses. Construct multi-step chains where the agent verifies pickup availability via `get_pickup_locations` before finalizing a reservation. Every step is traceable, so you know exactly why the agent chose a specific vehicle offer.

Dynamic reservation management

Manage your travel lifecycle by calling `book_car` within a structured chain. Your agent handles the confirmation flow, ensuring that the itinerary ID is captured for future reference. If travel plans change, trigger `cancel_itinerary` based on your agent's assessment of the booking status. It keeps your rental records clean and linked to the rest of your LangChain workflow.

Visual vehicle verification

Use `get_car_images` to pull exterior and interior shots into your agent's context. This helps the agent confirm the vehicle class matches the user's specific requirements before proceeding to booking. Pair this with `get_car_details` to provide full transparency on amenities and supplier rules. It gives your agent the data needed to explain the rental terms clearly to the end user.

Prerequisites

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

1

Install dependencies
Run pip install langchain-mcp-adapters langgraph langchain-openai. The MCP adapters package converts MCP tools into native LangChain BaseTool objects.

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