How to Use the Fuzzy Match Search MCP in OpenAI Agents SDK

Q: Can I use this to search for products in a catalog?

Yes. Feed the fuzzymatch tool your user's query and a JSON array of your product names or SKUs. It will return a ranked list of the most likely matches, which your agent can then present to the user.

Stop your OpenAI Agent from failing on typos. This server finds the closest string match so your agent's actions succeed.

Find What They Meant, Not What They Typed

Your agent asks for a customer name, the user types 'Jhon Doe'. Instead of failing a database lookup, your agent uses the `fuzzy_match` tool. It checks 'Jhon Doe' against your list of customers and gets back 'John Doe' with a high similarity score. Now the rest of your agent's workflow just works. The OpenAI SDK's built-in guardrails can confirm the corrected name before your agent updates a record or sends a message. No more failed actions from simple spelling mistakes.

Fast Typo Correction for your OpenAI Agent

This isn't some slow, clunky API. The `fuzzy_match` tool runs its Levenshtein-like algorithm in memory, usually in single-digit milliseconds. Your agent gets a response fast enough that it doesn't break the conversation's flow. Because the tool is exposed via a standard MCP Server, your agent discovers it automatically. There's no custom integration code to write. You just point the SDK at the server endpoint, and your agent can start correcting user input immediately.

Build More Resilient Agent Workflows

Imagine an agent that triages support tickets. It uses `fuzzy_match` to map a user's typed product name—like 'my fone screen is craacked'—to the official SKU 'iPhone 15 Pro Screen Assembly'. It then hands off that corrected SKU to a specialized RMA agent. The whole interaction is tracked in your OpenAI dashboard, so you can see exactly how the typo was corrected. This makes your multi-agent system more reliable and easier to debug.

Setup guide

Set up Fuzzy Match Search 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 Fuzzy Match Search tools at runtime.
3

Create your Agent

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

Run the agent

Call Runner.run(agent, prompt) to execute. The agent invokes the appropriate Fuzzy Match Search 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="Fuzzy Match Search Agent",
            instructions="You have access to Fuzzy Match Search tools.",
            mcp_servers=[server],
        )
        result = await Runner.run(agent, "List recent transactions")
        print(result.final_output)

asyncio.run(main())

Common questions about Fuzzy Match Search MCP in OpenAI Agents SDK

It lets your agent take a misspelled input, run it against a list of valid options with `fuzzy_match`, and find the correct one. This prevents the agent from failing its next action because of a simple typo.

Yes. Feed the `fuzzy_match` tool your user's query and a JSON array of your product names or SKUs. It will return a ranked list of the most likely matches, which your agent can then present to the user.

It's fast. The matching happens in-memory on the Vinkius server, not your agent's process. For most datasets, you'll get a response in milliseconds, so it won't slow down your agent's conversational turn.

The tool is designed for datasets that fit comfortably in memory, typically up to tens of thousands of strings. For massive datasets, you're better off pre-filtering with a database query first, then using `fuzzy_match` on the smaller result set.

Your search query and target string array are processed in an ephemeral, isolated sandbox on Vinkius. The data is only used for the duration of the `fuzzy_match` operation and is never logged or stored. The entire environment is wiped after your request is complete.
