How to Use the Capacities MCP in Google ADK

Q: How does Google ADK retrieve Capacities data?

Your agent calls getobject to pull specific records from your graph. It returns the full property set, allowing the model to reason over your existing notes.

Q: Can I filter Capacities tools in Google ADK?

You can restrict the exposed tools using the toolnames filter in your agent configuration. This limits what the agent can access in your workspace.

Connect your Google ADK enterprise agents to your Capacities workspace.

Google ADK agents reading Capacities spaces

Use `list_spaces` and `get_space_info` to map out your available containers. Your agents gain visibility into your existing structures before they attempt to write new data. This gives your agent a blueprint of your setup. It prevents errors by checking property requirements before sending new payloads.

Link media to records with Google ADK

Execute `save_media` to bind files directly to your nodes. Your agents can now process external assets and store them alongside your relevant research. It handles the binary attachment process, linking your files to the correct object ID. Your workspace stays organized without manual sorting.

Automated tagging via Google ADK workflows

Invoke `add_tag` to categorize entities as your agent processes information. It creates dynamic relations between your notes and existing tags. Your graph becomes more connected as your agent iterates. It reduces the effort required to maintain your personal knowledge structure.

Setup guide

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