Manage clients via Google ADK

Pull client records into your Google Cloud workflows. The `get_client` tool allows your agent to fetch specific billing profiles for high-context reasoning. Remove stale records efficiently. Use `delete_client` to purge deprecated entries directly from your terminal or script.

Process billing through Google ADK

Create invoices directly from your BigQuery data sources. Your agent maps your output to `create_invoice` to finalize pending charges. Track your receivables in real time. Use `list_invoices` to give your agent a snapshot of all outstanding balances.

Update records with this MCP Server

Modify client details on the fly. The `update_client` tool accepts JSON payloads to adjust addresses or billing terms without manual entry. Adjust invoice parameters as needed. Use `update_invoice` to revise line items before dispatching.

Setup guide

Set up Invoice Ninja (Invoicing & Billing) 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 Invoice Ninja (Invoicing & Billing) tools in your ADK agent.

Common questions about Invoice Ninja (Invoicing & Billing) MCP in Google ADK

The framework treats the server as a native toolset. Your agent interprets the schema and executes functions against your account.

Yes. You can restrict your agent to specific functions like `create_invoice` by using the tool_names filter during initialization.

It is. You can feed invoice lists into your Gemini context window for deep analysis of your financial trends.

Not at all. You point the toolset to your endpoint and the framework handles the rest of the connection logic.

We enforce strict zero-trust boundaries at the transport layer. Your sensitive client contact information is processed only in memory and never persisted in our logs.
