Direct word lookup for agents

Your OpenAI Agents SDK instance calls `get_word_definition` to fetch linguistic data in real-time. This bypasses manual lookups and keeps your agent focused on the task. Define your agent with the server injected. The tool appears automatically in your agent's capability set without manual mapping.

Validate definitions with guardrails

Use the OpenAI Agents SDK built-in guardrails to check the dictionary output before your agent acts on it. This prevents malformed data from reaching your end-users. Every call to `get_word_definition` passes through your defined safety layers. If the response structure shifts, the agent catches it instantly.

Trace dictionary requests

Monitor every `get_word_definition` execution through the OpenAI dashboard. You see exactly when and why your agent accessed the DictionaryAPI.dev MCP server. Debugging becomes trivial when you trace the input word against the final definition. This transparency ensures your production agents remain predictable.

Setup guide

Set up DictionaryAPI.dev 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 DictionaryAPI.dev tools at runtime.
3

Create your Agent

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

Run the agent

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

asyncio.run(main())

Common questions about DictionaryAPI.dev MCP in OpenAI Agents SDK

Use the MCPServerStreamableHttp class to point your agent at the server URL. Pass the instance into your agent constructor via mcp_servers. It connects and discovers tools immediately.

Yes, set cacheToolsList to true in your configuration. This stores the tool definitions locally, which speeds up your agent initialization time significantly.

The SDK treats dictionary errors like any other tool failure. Implement try-except blocks around your agent execution to catch and handle network issues gracefully.

This server only processes plain text word definitions. No private user data or sensitive credentials leave your environment during these lookups.

Response times depend on your network latency to the server. Most lookups resolve in milliseconds, making it suitable for standard agent workflows.
