How to Use the Buffer MCP in Google ADK

Q: How do I configure the Buffer MCP Server inside Google ADK?

Use McpToolset with StreamableHttpServerParameters pointing to your Vinkius endpoint URL. Pass this toolset into the tools parameter of your LlmAgent initialization block.

Q: Can I limit which Buffer tools the Google ADK agent can access?

Yes, you can pass a toolnames filter to the McpToolset constructor. This restricts the agent to specific actions like listpendingposts while blocking destructive actions like removesocialpost.

Q: How do I verify my Buffer credentials inside a Google Cloud environment?

Run the testbufferauth tool directly through your agent. This checks if your OAuth token is valid and active before running any complex scheduling workflows.

Let Gemini agents analyze BigQuery data and schedule Buffer posts using the Google ADK.

Google ADK pipeline for Buffer scheduling

The `schedule_social_post` tool gives your Gemini agent direct access to your queues. By combining this with Google ADK, your agent reads performance metrics from BigQuery and adjusts post timing instantly. The agent calls `list_published_posts` to gather historical performance, then feeds that context into Gemini's 1M-token window to draft highly optimized updates.

Long-context queue analysis via MCP Server

The `list_pending_posts` tool pulls your entire scheduled backlog into the Gemini context window. Google ADK processes this raw list alongside your corporate guidelines to check for scheduling conflicts. When it finds a gap, the agent executes `modify_posting_schedules` to space out the content. This keeps your feed active without manual developer intervention.

Enterprise profile management with Gemini

The `list_social_profiles` tool maps out every connected account in your enterprise workspace. Your Google ADK agent verifies account health by matching these profiles against your active campaigns. Before publishing, the agent runs `get_api_status` to confirm the channel is ready. If a channel goes offline, the agent alerts your team instead of failing silently.

Setup guide

Set up Buffer MCP in Google ADK

Prerequisites

Python 3.10+ installed
google-adk package (pip install google-adk)
Active Vinkius subscription with a valid endpoint token

1

Install Google ADK

Run pip install google-adk to install the Agent Development Kit. MCP support is included via the McpToolset class.
2

Connect via SSE transport

Use McpToolset.from_server() with SseServerParams pointing to your Vinkius endpoint. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Create an LlmAgent

Pass the returned mcp_tools list directly to LlmAgent(tools=mcp_tools). The ADK maps each MCP tool to a native Gemini function call — no manual schema definitions required.
4

Run with any Gemini model

The agent works with any Gemini model (gemini-2.0-flash, gemini-2.5-pro, etc.). Copy the full example on the right to get started with Buffer tools in your ADK agent.

agent.py

from google.adk.agents import LlmAgent
from google.adk.tools.mcp_tool.mcp_toolset import McpToolset
from google.adk.tools.mcp_tool.mcp_session_manager import SseServerParams

# Connect to the MCP via SSE
mcp_tools, exit_stack = await McpToolset.from_server(
    connection_params=SseServerParams(
        url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    )
)

# Create your agent with auto-discovered tools
agent = LlmAgent(
    name="Buffer_agent",
    model="gemini-2.0-flash",
    instruction="You have access to Buffer tools via MCP.",
    tools=mcp_tools,
)
