How to Use the LanceDB (Serverless Vector DB) MCP in OpenAI Agents SDK

Q: How do I configure LanceDB (Serverless Vector DB) inside the OpenAI Agents SDK?

Install the OpenAI SDK and use MCPServerStreamableHttp to connect to the Vinkius MCP endpoint. Pass this server instance inside the mcpservers list when initializing your OpenAI Agents SDK agent to auto-discover the vector tools.

Q: Can my OpenAI Agents SDK agent create and delete tables dynamically?

Yes, your OpenAI Agents SDK agent uses createtable to build LanceDB schemas on the fly and deletetable to remove them. This works well for multi-tenant setups where each OpenAI agent session requires an isolated vector partition.

Q: How does the OpenAI Agents SDK handle schema validation during LanceDB (Serverless Vector DB) insert operations?

The OpenAI Agents SDK relies on the insertrows tool to enforce the strict schema defined during LanceDB table creation. If your agent attempts to insert mismatched vector dimensions, the serverless database rejects the write instantly.

Q: What is the latency for a vectorsearch query using this MCP Server?

Queries executed via vectorsearch typically resolve in under 15 milliseconds. The Vinkius V8 Isolate Sandbox hosts the MCP Server close to your OpenAI Agents SDK runtime to minimize network roundtrips.

Run serverless vector operations directly from your OpenAI Agents SDK workflows with zero infrastructure overhead.

Dynamic Table Provisioning and Schema Enforcement

The `create_table` tool builds a new LanceDB table with a strict schema directly from your OpenAI Agents SDK runtime. When your OpenAI agent needs to isolate a new user session, it executes this operation to partition LanceDB vectors without manual database administration. Your OpenAI Agents SDK agent verifies the structure of existing tables using `get_table` before pushing updates. This prevents schema drift in production OpenAI Agents SDK deployments using this MCP Server by stopping mismatched vector shapes before they hit your disk.

High-Speed Similarity Search for OpenAI Agents SDK

The `vector_search` tool runs nearest-neighbor queries against your serverless LanceDB tables to find matching documents. Your OpenAI Agents SDK agent sends query vectors directly to this endpoint to pull relevant database context in under 15 milliseconds. By combining this search with `list_tables`, your OpenAI Agents SDK agent scans available vector spaces and selects the correct LanceDB index dynamically. This setup eliminates the need to hardcode LanceDB table names in your OpenAI agent's system prompts.

Atomic Row Insertion and Index Updates

The `insert_rows` tool pushes new multi-modal embeddings and metadata directly into active LanceDB tables. The underlying approximate nearest neighbor index updates automatically as new rows arrive, keeping your OpenAI Agents SDK search results fresh. If a table becomes obsolete, your OpenAI Agents SDK agent uses `delete_table` to purge the vector data completely. This combination lets OpenAI Agents SDK pipelines manage the entire LanceDB vector lifecycle without manual database cleanup scripts.

Setup guide

Set up LanceDB (Serverless Vector DB) 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 LanceDB (Serverless Vector DB) tools at runtime.
3

Create your Agent

Pass the MCP to Agent(mcp_servers=[server]). The agent receives LanceDB (Serverless Vector DB) tools as native definitions — JSON schemas resolve automatically.
4

Run the agent

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

asyncio.run(main())
