Perplexity

Break down URLs with parse_url

Your agent needs to deconstruct raw strings into usable data structures. Use `parse_url` to isolate the protocol, host, and path from any incoming URI. This tool handles the messy edge cases that break standard string splitting. You get a clean object ready for downstream logic within your agent workflow.

Extract query values reliably

Stop wrestling with complex regex for simple data retrieval. The `extract_query` tool grabs specific parameter values directly from the URL string. It avoids the common pitfalls of manual parsing. Your agent gets the exact value it needs to make decisions without risking malformed input.

Inject parameters with the Deterministic URL Engine

Updating tracking parameters is a common source of bugs. The `inject_query` tool handles the concatenation logic for you, ensuring your query strings remain valid. It manages the necessary ampersands and question marks automatically. Your OpenAI Agents SDK agents can now append new data to URLs without breaking the structure.

Setup guide

Set up Deterministic URL Engine MCP in OpenAI Agents SDK

Prerequisites

Python 3.10+ installed
openai-agents package (pip install openai-agents)
Active Vinkius subscription with a valid endpoint token

1

Install the SDK

Run pip install openai-agents to install the OpenAI Agents SDK. The MCP integration is built-in — no extra dependencies needed.
2

Connect via SSE transport

Use MCPServerSse with your Vinkius endpoint URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. The SDK auto-discovers all Deterministic URL Engine tools at runtime.
3

Create your Agent

Pass the MCP to Agent(mcp_servers=[server]). The agent receives Deterministic URL Engine tools as native definitions — JSON schemas resolve automatically.
4

Run the agent

Call Runner.run(agent, prompt) to execute. The agent invokes the appropriate Deterministic URL Engine tools and returns structured results. Copy the full example on the right to get started.

agent.py

import asyncio
from agents import Agent, Runner
from agents.mcp import MCPServerSse

async def main():
    async with MCPServerSse(
        url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    ) as server:
        agent = Agent(
            name="Deterministic URL Engine Agent",
            instructions="You have access to Deterministic URL Engine tools.",
            mcp_servers=[server],
        )
        result = await Runner.run(agent, "List recent transactions")
        print(result.final_output)

asyncio.run(main())
