How to Use the Affinity MCP in Google ADK

Q: Can Google ADK agents read Affinity meeting logs?

They can pull the exact chronological logs. The listinteractions tool feeds synced emails, calls, and meeting histories straight into Gemini's context window.

Q: Can I restrict my Google ADK agent to specific Affinity tools?

You pass a toolnames filter when configuring the toolset. This prevents the agent from calling tools you want to keep off-limits.

Perplexity

Feed BigQuery with MCP Server data

Enterprise agents need massive context windows to make sense of complex relationship graphs. Connecting this server via McpToolset lets your Gemini model ingest huge chunks of your CRM history at once. It can run `list_interactions` to dump thousands of logged emails and meetings straight into that 1M+ token window. Cross-referencing this data against your existing Google Cloud infrastructure changes how you operate. Your agent pulls raw contact histories from Affinity and immediately joins them with internal customer records sitting in BigQuery.

Map corporate networks

Finding the right entry point into a target account requires knowing who talked to whom. The `list_organizations` and `list_persons` tools give your LlmAgent the exact company structures and contact nodes mapped within your network. Your script builds a complete relationship web in seconds. You can filter exposed tools if you only want the agent mapping companies and not reading emails. Passing a tool_names filter to the toolset keeps the Gemini model focused strictly on structural CRM data.

Track pipeline movement

Custom pipelines hold the actual truth about your deal flow. Your agent hits `list_smart_lists` to grab the catalog of configured lists, then follows up with `list_list_entries` to see exactly which people sit in those specific stages. Running this on Vertex AI means you can schedule these pipeline checks to run autonomously. The agent reads the current Affinity state, compares it to yesterday's BigQuery snapshot, and flags stalled deals automatically.

Setup guide

Set up Affinity 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 Affinity 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="Affinity_agent",
    model="gemini-2.0-flash",
    instruction="You have access to Affinity tools via MCP.",
    tools=mcp_tools,
)

Common questions about Affinity MCP in Google ADK

Install google-adk and set up an McpToolset using StreamableHttpServerParameters with your Vinkius URL. Pass that toolset directly to your LlmAgent constructor.

They can pull the exact chronological logs. The list_interactions tool feeds synced emails, calls, and meeting histories straight into Gemini's context window.

Yes, it does. You can dump massive amounts of CRM data from your lists and let the model reason across the entire relationship graph at once.

You pass a tool_names filter when configuring the toolset. This prevents the agent from calling tools you want to keep off-limits.

The connection runs through a zero-trust, ephemeral environment. Your proprietary smart lists and mapped network contacts never leak, requiring only a secure endpoint token to authenticate the proxy.
