Automate your social pipeline with OpenAI Agents SDK

The `create_update` tool lets your agent write, format, and schedule posts across all your connected social channels. Using this MCP integration, your agent evaluates your content schedule, drafts the copy, and queues it up with the correct links automatically. By combining this with `list_pending_updates` and `reorder_updates`, your autonomous agent can audit your queue and re-arrange posts depending on current performance trends. It keeps your feed active without you ever opening a dashboard.

Keep your feed fresh without manual oversight

The `shuffle_updates` tool mixes up your scheduled queue to keep your content distribution looking organic. If your agent detects that too many similar posts are clustered together, it triggers this shuffle to vary the topics your audience sees. You can also call `delete_update` to pull a scheduled post if a sudden shift in company news makes it irrelevant. It gives your automated system the judgment to clean up the queue instantly.

Inspect active profiles via this MCP Server

The `list_profiles` tool fetches details about every connected social media account so your agent knows where it is allowed to publish. This MCP Server checks platform rules and limits before trying to post, preventing API errors before they happen. Your agent uses `get_profile` and `get_config` to understand what formats each network supports. This ensures a Twitter post stays under the character limit while a LinkedIn post gets the right link treatment.

Setup guide

Set up Buffer 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 Buffer tools at runtime.
3

Create your Agent

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

Run the agent

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

asyncio.run(main())

Common questions about Buffer MCP in OpenAI Agents SDK

Install the SDK using pip, then initialize the server with the HTTP endpoint. Pass the server instance directly into your Agent constructor using the mcp_servers list.

Yes, the SDK provides built-in guardrails to validate agent actions before they run. You can configure safety checks to ensure your agent doesn't write or delete updates without passing your validation rules.

Yes, you can have a specialized drafting agent write the copy, then hand off the execution to a publishing agent that calls the scheduling tools.

Set the cacheToolsList parameter to True when creating your server stream. This prevents the agent from querying the server for its tool list on every single turn.

Your social profiles and drafted posts are protected inside Vinkius's zero-trust sandboxed environment. The server uses ephemeral isolates, meaning your authentication tokens are never stored or logged on our host systems.
