By the end, you'll have a working Gagelist agent that can add a new calibration record for this gage, generate calibration certificate for equipment id 2345, list all gages due for calibration this month through natural language commands. This guide will help you understand how to give your Google ADK agent real control over a Gagelist account through Composio's Gagelist MCP server. Before we dive in, let's take a quick look at the key ideas and tools involved. ## Also integrate Gagelist with - [OpenAI Agents SDK](https://composio.dev/toolkits/gagelist/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/gagelist/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/gagelist/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/gagelist/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/gagelist/framework/codex) - [OpenClaw](https://composio.dev/toolkits/gagelist/framework/openclaw) - [Hermes](https://composio.dev/toolkits/gagelist/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/gagelist/framework/cli) - [LangChain](https://composio.dev/toolkits/gagelist/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/gagelist/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/gagelist/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/gagelist/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/gagelist/framework/crew-ai) ## TL;DR Here's what you'll learn: - Get a Gagelist account set up and connected to Composio - Install the Google ADK and Composio packages - Create a Composio Tool Router session for Gagelist - Build an agent that connects to Gagelist through MCP - Interact with Gagelist using natural language ## What is Google ADK? Google ADK (Agents Development Kit) is Google's framework for building AI agents powered by Gemini models. It provides tools for creating agents that can use external services through the Model Context Protocol. Key features include: - Gemini Integration: Native support for Google's Gemini models - MCP Toolset: Built-in support for Model Context Protocol tools - Streamable HTTP: Connect to external services through streamable HTTP - CLI and Web UI: Run agents via command line or web interface ## What is the Gagelist MCP server, and what's possible with it? The Gagelist MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Gagelist account. It provides structured and secure access to your calibration records and asset management workflows, so your agent can perform actions like adding new gages, managing calibration events, generating certificates, and retrieving account information on your behalf. - Seamless calibration record management: Direct your agent to add, update, or delete calibration records, keeping your asset compliance up-to-date with minimal manual effort. - Automated gage and manufacturer tracking: Have the agent add new gages or manufacturers to your Gagelist inventory, or remove outdated entries as your equipment changes. - Instant calibration certificate generation: Let your agent generate official PDF calibration certificates from existing records, streamlining audit and reporting processes. - Account insights and status checks: Quickly retrieve your account settings or overall status, giving you a real-time view into your calibration program's health. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `GAGELIST_ADD_CALIBRATION_RECORD` | Add Calibration Record | Creates a new calibration record in GageList to document equipment calibration results.

It provides structured and secure access so your agent can perform Gagelist operations on your behalf through a secure, permission-based interface. With Composio's managed implementation, you don't have to create your own developer app. For production, if you're building an end product, we recommend using your own credentials. The managed server helps you prototype fast and go from 0-1 faster. ## Step-by-step Guide ### 1. Prerequisites Before starting, make sure you have: - A Google API key for Gemini models - A Composio account and API key - Python 3.9 or later installed - Basic familiarity with Python ### 1. Getting API Keys for Google and Composio Google API Key - Go to [Google AI Studio](https://aistudio.google.com/app/apikey) and create an API key. - Copy the key and keep it safe. You will put this in GOOGLE_API_KEY. Composio API Key and User ID - Log in to the [Composio dashboard](https://dashboard.composio.dev?utm_source=toolkits&utm_medium=framework_docs). - Go to Settings → API Keys and copy your Composio API key. Use this for COMPOSIO_API_KEY. - Decide on a stable user identifier to scope sessions, often your email or a user ID. Use this for COMPOSIO_USER_ID. ### 2. Install dependencies Inside your virtual environment, install the required packages. What's happening: - google-adk is Google's Agents Development Kit - composio connects your agent to Gagelist via MCP - python-dotenv loads environment variables ```bash pip install google-adk composio python-dotenv ``` ### 3. Set up ADK project Set up a new Google ADK project. What's happening: - This creates an agent folder with a root agent file and .env file ```bash adk create my_agent ``` ### 4. Set environment variables Save all your credentials in the .env file. What's happening: - GOOGLE_API_KEY authenticates with Google's Gemini models - COMPOSIO_API_KEY authenticates with Composio - COMPOSIO_USER_ID identifies the user for session management ```bash GOOGLE_API_KEY=your-google-api-key COMPOSIO_API_KEY=your-composio-api-key COMPOSIO_USER_ID=your-user-id-or-email ``` ### 5. Import modules and validate environment What's happening: - os reads environment variables - Composio is the main Composio SDK client - GoogleProvider declares that you are using Google ADK as the agent runtime - Agent is the Google ADK LLM agent class - McpToolset lets the ADK agent call MCP tools over HTTP ```python import os import warnings from composio import Composio from dotenv import load_dotenv from google.adk.agents.llm_agent import Agent from google.adk.tools.mcp_tool.mcp_session_manager import StreamableHTTPConnectionParams from google.adk.tools.mcp_tool.mcp_toolset import McpToolset load_dotenv() warnings.filterwarnings("ignore", message=".*BaseAuthenticatedTool.*") GOOGLE_API_KEY = os.getenv("GOOGLE_API_KEY") COMPOSIO_API_KEY = os.getenv("COMPOSIO_API_KEY") COMPOSIO_USER_ID = os.getenv("COMPOSIO_USER_ID") if not GOOGLE_API_KEY: raise ValueError("GOOGLE_API_KEY is not set in the environment.") if not COMPOSIO_API_KEY: raise ValueError("COMPOSIO_API_KEY is not set in the environment.") if not COMPOSIO_USER_ID: raise ValueError("COMPOSIO_USER_ID is not set in the environment.") ``` ### 6. Create Composio client and Tool Router session What's happening: - Authenticates to Composio with your API key - Declares Google ADK as the provider - Spins up a short-lived MCP endpoint for your user and selected toolkit - Stores the MCP HTTP URL for the ADK MCP integration ```python composio_client = Composio(api_key=COMPOSIO_API_KEY) composio_session = composio_client.create( user_id=COMPOSIO_USER_ID, toolkits=["gagelist"], ) COMPOSIO_MCP_URL = composio_session.mcp.url, print(f"Composio MCP URL: {COMPOSIO_MCP_URL}") ``` ### 7. Set up the McpToolset and create the Agent What's happening: - Connects the ADK agent to the Composio MCP endpoint through McpToolset - Uses Gemini as the model powering the agent - Lists exact tool names in instruction to reduce misnamed tool calls ```python composio_toolset = McpToolset( connection_params=StreamableHTTPConnectionParams( url=COMPOSIO_MCP_URL, headers={"x-api-key": COMPOSIO_API_KEY} ) ) root_agent = Agent( model="gemini-2.5-flash", name="composio_agent", description="An agent that uses Composio tools to perform actions.", instruction=( "You are a helpful assistant connected to Composio. " "You have the following tools available: " "COMPOSIO_SEARCH_TOOLS, COMPOSIO_MULTI_EXECUTE_TOOL, " "COMPOSIO_MANAGE_CONNECTIONS, COMPOSIO_REMOTE_BASH_TOOL, COMPOSIO_REMOTE_WORKBENCH. " "Use these tools to help users with Gagelist operations." ), tools=[composio_toolset], ) print("\nAgent setup complete. You can now run this agent directly ;)") ``` ### 8. Run the agent Execute the agent from the project root. The web command opens a web portal where you can chat with the agent. What's happening: - adk run runs the agent in CLI mode - adk web . opens a web UI for interactive testing ```bash # Run in CLI mode adk run my_agent # Or run in web UI mode adk web ``` ## Complete Code ```python import os import warnings from composio import Composio from composio_google import GoogleProvider from dotenv import load_dotenv from google.adk.agents.llm_agent import Agent from google.adk.tools.mcp_tool.mcp_session_manager import StreamableHTTPConnectionParams from google.adk.tools.mcp_tool.mcp_toolset import McpToolset load_dotenv() warnings.filterwarnings("ignore", message=".*BaseAuthenticatedTool.*") GOOGLE_API_KEY = os.getenv("GOOGLE_API_KEY") COMPOSIO_API_KEY = os.getenv("COMPOSIO_API_KEY") COMPOSIO_USER_ID = os.getenv("COMPOSIO_USER_ID") if not GOOGLE_API_KEY: raise ValueError("GOOGLE_API_KEY is not set in the environment.") if not COMPOSIO_API_KEY: raise ValueError("COMPOSIO_API_KEY is not set in the environment.") if not COMPOSIO_USER_ID: raise ValueError("COMPOSIO_USER_ID is not set in the environment.") composio_client = Composio(api_key=COMPOSIO_API_KEY, provider=GoogleProvider()) composio_session = composio_client.create( user_id=COMPOSIO_USER_ID, toolkits=["gagelist"], ) COMPOSIO_MCP_URL = composio_session.mcp.url composio_toolset = McpToolset( connection_params=StreamableHTTPConnectionParams( url=COMPOSIO_MCP_URL, headers={"x-api-key": COMPOSIO_API_KEY} ) ) root_agent = Agent( model="gemini-2.5-flash", name="composio_agent", description="An agent that uses Composio tools to perform actions.", instruction=( "You are a helpful assistant connected to Composio. " "You have the following tools available: " "COMPOSIO_SEARCH_TOOLS, COMPOSIO_MULTI_EXECUTE_TOOL, " "COMPOSIO_MANAGE_CONNECTIONS, COMPOSIO_REMOTE_BASH_TOOL, COMPOSIO_REMOTE_WORKBENCH. " "Use these tools to help users with Gagelist operations." ), tools=[composio_toolset], ) print("\nAgent setup complete. You can now run this agent directly ;)") ``` ## Conclusion You've successfully integrated Gagelist with the Google ADK through Composio's MCP Tool Router. Your agent can now interact with Gagelist using natural language commands. Key takeaways: - The Tool Router approach dynamically routes requests to the appropriate Gagelist tools - Environment variables keep your credentials secure and separate from code - Clear agent instructions reduce tool calling errors - The ADK web UI provides an interactive interface for testing and development You can extend this setup by adding more toolkits to the toolkits array in your session configuration. ## How to build Gagelist MCP Agent with another framework - [OpenAI Agents SDK](https://composio.dev/toolkits/gagelist/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/gagelist/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/gagelist/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/gagelist/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/gagelist/framework/codex) - [OpenClaw](https://composio.dev/toolkits/gagelist/framework/openclaw) - [Hermes](https://composio.dev/toolkits/gagelist/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/gagelist/framework/cli) - [LangChain](https://composio.dev/toolkits/gagelist/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/gagelist/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/gagelist/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/gagelist/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/gagelist/framework/crew-ai) ## Related Toolkits - [Google Sheets](https://composio.dev/toolkits/googlesheets) - Google Sheets is a cloud-based spreadsheet tool for real-time collaboration and data analysis.

With a standalone Gagelist MCP server, the agents and LLMs can only access a fixed set of Gagelist tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Gagelist and many other apps based on the task at hand, all through a single MCP endpoint. ### Can I use Tool Router MCP with Google ADK? Yes, you can. Google ADK fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Gagelist tools. ### Can I manage the permissions and scopes for Gagelist while using Tool Router? Yes, absolutely. You can configure which Gagelist scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do. ### How safe is my data with Composio Tool Router? All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Gagelist data and credentials are handled as safely as possible. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
