How to Use the Bill.com MCP in Google ADK

Q: Can I restrict which Bill.com tools my Google ADK agent uses?

You can use the toolnames filter during setup. This limits the agent to only the specific operations you want to expose.

Google ADK agents accessing Bill.com records

Your Gemini models need accurate financial context to make decisions. The `get_company_profile` and `list_bills` tools provide this data instantly within your Google Cloud workflow. Agents process these long-context inputs to summarize outstanding liabilities. You get high-level financial intelligence without writing custom API wrappers.

Automating Bill.com workflows in Google ADK

Use `create_bill` to push new expenses from your internal systems directly to your finance stack. Your agent manages the entire lifecycle of a bill from creation to status check. This removes the need for manual dashboard monitoring. Your agent acts as a controller that keeps your accounts payable clean and updated.

Syncing vendor data with Google ADK

Keep your contact lists in sync across platforms using `list_vendors`. Your agent can compare external data against your Bill.com records to find discrepancies. It handles the heavy lifting of data matching. This keeps your records consistent without human intervention or spreadsheet exports.

Setup guide

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