# toolbox-adk — Agent Development Kit Integration for MCP Toolbox

License: permissive · Maintenance: active · Downloads: 251.7K/mo

## What it is and what it does

toolbox-adk is a Python SDK that bridges Google's Agent Development Kit (ADK) with the MCP Toolbox, allowing agents built on ADK to directly invoke tools from the MCP Toolbox ecosystem. It acts as an integration layer that handles the protocol translation and authentication plumbing between the two frameworks.

The package is designed for developers building AI agents on Google ADK who need access to MCP Toolbox's tool catalog. It handles transport protocols, authentication (via google-auth and google-auth-oauthlib), and provides configuration hooks for advanced use cases like OpenTelemetry observability. The package is actively maintained and supports modern Python versions (3.10 through 3.14).

Use it for:

- Integrate MCP Toolbox tools into Google ADK agents for expanded tool availability
- Build multi-tool AI agents that combine ADK capabilities with MCP Toolbox resources
- Set up authenticated tool access for agents requiring Google Cloud credentials
- Configure observability for agent-to-tool interactions via OpenTelemetry
- Develop agents that need both ADK-native and MCP Toolbox tools in a single codebase

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Enables Google ADK agents to natively use tools from the MCP Toolbox through a Python SDK integration layer.

Yes. This package is actively maintained, has low install friction, carries no known vulnerabilities, and uses a permissive Apache 2.0 license. Install it if you are building Google ADK agents and need access to MCP Toolbox tools. The recent release cadence and 191 GitHub stars indicate active development and community use.

## Install

pip install toolbox-adk
uv add toolbox-adk
poetry add toolbox-adk

## Installing toolbox-adk

Before you install: Low install friction with a pure-Python wheel. Actively maintained as of 2026-08-14 with recent releases. Depends on toolbox-core, google-auth, google-auth-oauthlib, google-adk, and typing-extensions—all standard Google ecosystem packages.

License in practice: Licensed under Apache License 2.0 (permissive). You can use, modify, and distribute this package freely in commercial and private projects with minimal restrictions.

Quickstart:

pip install toolbox-adk

from toolbox_adk import ToolboxClient

client = ToolboxClient()
# Configure transport and authentication per documentation

Requires Python 3.10 or later. Google authentication credentials must be configured for the ADK agent.

Verify before relying:

- Specific transport protocol options and their performance characteristics
- Whether OpenTelemetry integration is automatic or requires explicit setup
- Compatibility matrix with specific ADK and MCP Toolbox versions
