## TL;DR

Here's what you'll learn:
- Get a Firmao account set up and connected to Composio
- Install the Google ADK and Composio packages
- Create a Composio Tool Router session for Firmao
- Build an agent that connects to Firmao through MCP
- Interact with Firmao 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 Firmao MCP server, and what's possible with it?

The Firmao MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Firmao account. It provides structured and secure access to your business data, so your agent can perform actions like retrieving invoices, managing offers, handling tasks, and updating company settings on your behalf.
- Invoice management and automation: Let your agent create new invoices, retrieve detailed invoice data, list all invoices, or delete invoices as needed—all without manual entry.
- Offer tracking and updates: Effortlessly get the details of any offer, or have your agent delete offers that are no longer relevant to your business pipeline.
- Task and contact handling: Fetch specific task details or manage your contact list, including the ability to remove outdated or incorrect contacts with ease.
- Company configuration oversight: List and review your company’s settings or delete obsolete company configurations—helping you keep your business data clean and up to date.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `FIRMAO_CREATE_INVOICE` | Create Invoice | Creates a new sales or purchase invoice in Firmao CRM. This action generates an invoice transaction with line items, customer information, pricing details, and payment terms. It can auto-create customers if needed and supports automatic invoice numbering. |
| `FIRMAO_DELETE_COMPANY_SETTING` | Delete Company Setting | Deletes a company setting by its unique identifier. Returns success status and details about the deletion attempt. Use this when you need to permanently remove a specific company setting configuration. |
| `FIRMAO_DELETE_CONTACT` | Delete Contact | Soft-deletes a contact in Firmao CRM by marking it as deleted (sets deleted=true). This action sends a PUT request to mark the contact as deleted without permanently removing it from the system. The contact can potentially be restored later through the Firmao interface. Returns a changelog documenting the deletion operation. If the API returns errors (e.g., authentication issues, contact not found, insufficient permissions), the action gracefully returns an empty changelog to maintain usability in restricted environments. Use this when you need to remove a contact from active use in Firmao CRM. |
| `FIRMAO_DELETE_INVOICE` | Delete Invoice | Soft-deletes a Firmao invoice by marking it as deleted. This action sends a PUT request to mark the invoice's 'deleted' field as true. The invoice record remains in the system but is marked as deleted. Returns a changelog documenting the deletion operation. If the API returns unexpected response formats, the action normalizes them to the expected schema. |
| `FIRMAO_DELETE_OFFER` | Delete Offer | Soft-delete an offer in Firmao by marking it as deleted. The offer record is not permanently removed but is marked with deleted=true, making it inactive in the system. Use this action when you need to remove an offer without permanently destroying the record. The action returns a changelog documenting the deletion operation. |
| `FIRMAO_GET_INVOICE` | Get Invoice | Retrieve detailed information about a specific invoice by its ID. Returns comprehensive invoice data including customer details, line items, payment status, pricing information, and metadata. Use this when you need complete invoice details for a known invoice ID. |
| `FIRMAO_GET_OFFER` | Get Offer | Retrieve detailed information about a specific offer from Firmao CRM by its unique ID. This action fetches comprehensive offer data including customer details, pricing, line items, payment information, and metadata. Use this when you need to view or analyze a specific offer, display offer details to users, or retrieve offer information for further processing. The action implements robust endpoint fallback logic to handle various Firmao API configurations. Returns an empty result set if the offer is not found or authentication fails. |
| `FIRMAO_GET_TASK` | Get Task | Retrieves detailed information about a specific task by its unique ID. Use this action when you need to: - Get full details of a task after obtaining its ID from a list or search - Check the current status, progress, or assignments of a specific task - Access task metadata like creation date, responsible users, or financial information Returns a single task's complete information including status, dates, responsible users, progress percentage, financial data (costs, income), and related entities (customer, contact, project). |
| `FIRMAO_LIST_COMPANY_SETTINGS` | List Company Settings | Lists all company settings from Firmao. Company settings are key-value configuration pairs that store custom configurations for companies. Use this action to retrieve settings, with optional filtering by company ID and pagination support. Returns an empty list if no settings exist or the endpoint is not available in the current Firmao deployment. |
| `FIRMAO_LIST_INVOICES` | List Invoices | Tool to list invoices. Use when retrieving a list of invoices with optional pagination and filtering. |
| `FIRMAO_LIST_TASKS` | List Tasks | Retrieves a paginated list of tasks from Firmao. Returns task details including status, priority, dates, responsible users, tags, and financial data. Supports sorting, filtering by various fields, and configurable detail levels (MINIMAL, MEDIUM, FULL). |
| `FIRMAO_UPDATE_CONTACT` | Update Contact in Firmao | Updates an existing contact in Firmao CRM by its ID. Use this tool to modify contact information such as name, email, phone, position, or customer association. Only include the fields you want to change - omitted fields will remain unchanged. Returns a changelog of the modifications made. Prerequisites: - The contact ID must exist in your Firmao organization - If updating the customer field, the customer ID must already exist |
| `FIRMAO_UPDATE_OFFER` | Update Offer | Updates an existing offer/quote in Firmao by ID. Modifies specified fields while preserving unspecified ones. Returns a changelog detailing what changed. Supports partial updates - only provide fields you want to change. |
| `FIRMAO_UPDATE_TASK` | Update Task | Tool to update an existing task. Use when you need to modify one or more fields of a task after confirming its current details. |

## Creating MCP Server - Stand-alone vs Composio SDK

The Firmao MCP server is an implementation of the Model Context Protocol that connects your AI agent to Firmao. It provides structured and secure access so your agent can perform Firmao 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 Firmao 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=["firmao"],
)

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 Firmao 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=["firmao"],
)

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 Firmao operations."
    ),  
    tools=[composio_toolset],
)

print("\nAgent setup complete. You can now run this agent directly ;)")
```

## Conclusion

You've successfully integrated Firmao with the Google ADK through Composio's MCP Tool Router. Your agent can now interact with Firmao using natural language commands.
Key takeaways:
- The Tool Router approach dynamically routes requests to the appropriate Firmao 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.

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Firmao MCP?

With a standalone Firmao MCP server, the agents and LLMs can only access a fixed set of Firmao tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Firmao 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 Firmao tools.

### Can I manage the permissions and scopes for Firmao while using Tool Router?

Yes, absolutely. You can configure which Firmao 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 Firmao data and credentials are handled as safely as possible.
