Instant word definitions for agents

Your agent calls `define_word` to pull authoritative dictionary entries during execution. This eliminates guessing when your agent encounters technical jargon or archaic terminology. By integrating this MCP Server, your agent accesses verified data rather than relying on internal model weights. It keeps your output grounded in standard English.

Thesaurus access in your Python code

Trigger `get_thesaurus` whenever your agent needs to refine its tone or avoid repetition. You get structured lists of synonyms and antonyms returned directly to your agent's logic flow. This tool ensures your agent maintains consistent professional quality. It prevents the repetitive phrasing often found in raw model responses.

Reliable semantic validation

Use this MCP Server to verify word usage within your agent's guardrails. By checking definitions before finalizing a response, you prevent common linguistic errors. This setup creates a feedback loop for your agent. It ensures your final output remains accurate without manual oversight.

Setup guide

Set up Merriam-Webster 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 Merriam-Webster tools at runtime.
3

Create your Agent

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

Run the agent

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

asyncio.run(main())
