## Introduction

Codex is one of the most popular coding harnesses out there. And MCP makes the experience even better. With Firmao MCP integration, you can draft, triage, summarise emails, and much more, all without leaving the terminal or the app, whichever you prefer.

## TL;DR

### Why use Composio?
Apart from a managed and hosted MCP server, you will get:
- CodeAct: A dedicated workbench that allows GPT to write its code to handle complex tool chaining. Reduces to-and-fro with LLMs for frequent tool calling.
- Large tool responses: Handle them to minimise context rot.
- Dynamic just-in-time access to 20,000 tools across 1000+ other Apps for cross-app workflows. It loads the tools you need, so GPTs aren't overwhelmed by tools you don't need.

## Connect Firmao to Codex

### How to install Firmao MCP in Codex
### Run the setup command
Run this command in your terminal to add the Composio MCP server to Codex.

```bash
codex mcp add composio --url https://connect.composio.dev/mcp
```

## 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- Task and contact handling: Fetch specific task details or manage your contact list, including the ability to remove outdated or incorrect contacts with ease.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. |

## 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 Codex?

Yes, you can. Codex 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.
