By the end, you'll have a working Firmao agent that can list all invoices created this month, get details for invoice id 12345, delete a contact named john doe through natural language commands. This guide will help you understand how to give your Mastra AI agent real control over a Firmao account through Composio's Firmao MCP server. Before we dive in, let's take a quick look at the key ideas and tools involved. ## Also integrate Firmao with - [OpenAI Agents SDK](https://composio.dev/toolkits/firmao/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/firmao/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/firmao/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/firmao/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/firmao/framework/codex) - [OpenClaw](https://composio.dev/toolkits/firmao/framework/openclaw) - [Hermes](https://composio.dev/toolkits/firmao/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/firmao/framework/cli) - [Google ADK](https://composio.dev/toolkits/firmao/framework/google-adk) - [LangChain](https://composio.dev/toolkits/firmao/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/firmao/framework/ai-sdk) - [LlamaIndex](https://composio.dev/toolkits/firmao/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/firmao/framework/crew-ai) ## TL;DR Here's what you'll learn: - Set up your environment so Mastra, OpenAI, and Composio work together - Create a Tool Router session in Composio that exposes Firmao tools - Connect Mastra's MCP client to the Composio generated MCP URL - Fetch Firmao tool definitions and attach them as a toolset - Build a Mastra agent that can reason, call tools, and return structured results - Run an interactive CLI where you can chat with your Firmao agent ## What is Mastra AI? Mastra AI is a TypeScript framework for building AI agents with tool support. It provides a clean API for creating agents that can use external services through MCP. Key features include: - MCP Client: Built-in support for Model Context Protocol servers - Toolsets: Organize tools into logical groups - Step Callbacks: Monitor and debug agent execution - OpenAI Integration: Works with OpenAI models via @ai-sdk/openai ## 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. | ## Supported Triggers None listed. ## 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: - Node.js 18 or higher - A Composio account with an active API key - An OpenAI API key - Basic familiarity with TypeScript ### 1. Getting API Keys for OpenAI and Composio OpenAI API Key - Go to the [OpenAI dashboard](https://platform.openai.com/settings/organization/api-keys) and create an API key. - You need credits or a connected billing setup to use the models. - Store the key somewhere safe. Composio API Key - Log in to the [Composio dashboard](https://dashboard.composio.dev?utm_source=toolkits&utm_medium=framework_docs). - Go to Settings and copy your API key. - This key lets your Mastra agent talk to Composio and reach Firmao through MCP. ### 2. Install dependencies Install the required packages. What's happening: - @composio/core is the Composio SDK for creating MCP sessions - @mastra/core provides the Agent class - @mastra/mcp is Mastra's MCP client - @ai-sdk/openai is the model wrapper for OpenAI - dotenv loads environment variables from .env ```bash npm install @composio/core @mastra/core @mastra/mcp @ai-sdk/openai dotenv ``` ### 3. Set up environment variables Create a .env file in your project root. What's happening: - COMPOSIO_API_KEY authenticates your requests to Composio - COMPOSIO_USER_ID tells Composio which user this session belongs to - OPENAI_API_KEY lets the Mastra agent call OpenAI models ```bash COMPOSIO_API_KEY=your_composio_api_key_here COMPOSIO_USER_ID=your_user_id_here OPENAI_API_KEY=your_openai_api_key_here ``` ### 4. Import libraries and validate environment What's happening: - dotenv/config auto loads your .env so process.env.* is available - openai gives you a Mastra compatible model wrapper - Agent is the Mastra agent that will call tools and produce answers - MCPClient connects Mastra to your Composio MCP server - Composio is used to create a Tool Router session ```typescript import "dotenv/config"; import { openai } from "@ai-sdk/openai"; import { Agent } from "@mastra/core/agent"; import { MCPClient } from "@mastra/mcp"; import { Composio } from "@composio/core"; import * as readline from "readline"; import type { AiMessageType } from "@mastra/core/agent"; const openaiAPIKey = process.env.OPENAI_API_KEY; const composioAPIKey = process.env.COMPOSIO_API_KEY; const composioUserID = process.env.COMPOSIO_USER_ID; if (!openaiAPIKey) throw new Error("OPENAI_API_KEY is not set"); if (!composioAPIKey) throw new Error("COMPOSIO_API_KEY is not set"); if (!composioUserID) throw new Error("COMPOSIO_USER_ID is not set"); const composio = new Composio({ apiKey: composioAPIKey as string, }); ``` ### 5. Create a Tool Router session for Firmao What's happening: - create spins up a short-lived MCP HTTP endpoint for this user - The toolkits array contains "firmao" for Firmao access - session.mcp.url is the MCP URL that Mastra's MCPClient will connect to ```typescript async function main() { const session = await composio.create( composioUserID as string, { toolkits: ["firmao"], }, ); const composioMCPUrl = session.mcp.url; console.log("Firmao MCP URL:", composioMCPUrl); ``` ### 6. Configure Mastra MCP client and fetch tools What's happening: - MCPClient takes an id for this client and a list of MCP servers - The headers property includes the x-api-key for authentication - getTools fetches the tool definitions exposed by the Firmao toolkit ```typescript const mcpClient = new MCPClient({ id: composioUserID as string, servers: { nasdaq: { url: new URL(composioMCPUrl), requestInit: { headers: session.mcp.headers, }, }, }, timeout: 30_000, }); console.log("Fetching MCP tools from Composio..."); const composioTools = await mcpClient.getTools(); console.log("Number of tools:", Object.keys(composioTools).length); ``` ### 7. Create the Mastra agent What's happening: - Agent is the core Mastra agent - name is just an identifier for logging and debugging - instructions guide the agent to use tools instead of only answering in natural language - model uses openai("gpt-5") to configure the underlying LLM ```typescript const agent = new Agent({ name: "firmao-mastra-agent", instructions: "You are an AI agent with Firmao tools via Composio.", model: "openai/gpt-5", }); ``` ### 8. Set up interactive chat interface What's happening: - messages keeps the full conversation history in Mastra's expected format - agent.generate runs the agent with conversation history and Firmao toolsets - maxSteps limits how many tool calls the agent can take in a single run - onStepFinish is a hook that prints intermediate steps for debugging ```typescript let messages: AiMessageType[] = []; console.log("Chat started! Type 'exit' or 'quit' to end.\n"); const rl = readline.createInterface({ input: process.stdin, output: process.stdout, prompt: "> ", }); rl.prompt(); rl.on("line", async (userInput: string) => { const trimmedInput = userInput.trim(); if (["exit", "quit", "bye"].includes(trimmedInput.toLowerCase())) { console.log("\nGoodbye!"); rl.close(); process.exit(0); } if (!trimmedInput) { rl.prompt(); return; } messages.push({ id: crypto.randomUUID(), role: "user", content: trimmedInput, }); console.log("\nAgent is thinking...\n"); try { const response = await agent.generate(messages, { toolsets: { firmao: composioTools, }, maxSteps: 8, }); const { text } = response; if (text && text.trim().length > 0) { console.log(`Agent: ${text}\n`); messages.push({ id: crypto.randomUUID(), role: "assistant", content: text, }); } } catch (error) { console.error("\nError:", error); } rl.prompt(); }); rl.on("close", async () => { console.log("\nSession ended."); await mcpClient.disconnect(); process.exit(0); }); } main().catch((err) => { console.error("Fatal error:", err); process.exit(1); }); ``` ## Complete Code ```typescript import "dotenv/config"; import { openai } from "@ai-sdk/openai"; import { Agent } from "@mastra/core/agent"; import { MCPClient } from "@mastra/mcp"; import { Composio } from "@composio/core"; import * as readline from "readline"; import type { AiMessageType } from "@mastra/core/agent"; const openaiAPIKey = process.env.OPENAI_API_KEY; const composioAPIKey = process.env.COMPOSIO_API_KEY; const composioUserID = process.env.COMPOSIO_USER_ID; if (!openaiAPIKey) throw new Error("OPENAI_API_KEY is not set"); if (!composioAPIKey) throw new Error("COMPOSIO_API_KEY is not set"); if (!composioUserID) throw new Error("COMPOSIO_USER_ID is not set"); const composio = new Composio({ apiKey: composioAPIKey as string }); async function main() { const session = await composio.create(composioUserID as string, { toolkits: ["firmao"], }); const composioMCPUrl = session.mcp.url; const mcpClient = new MCPClient({ id: composioUserID as string, servers: { firmao: { url: new URL(composioMCPUrl), requestInit: { headers: session.mcp.headers, }, }, }, timeout: 30_000, }); const composioTools = await mcpClient.getTools(); const agent = new Agent({ name: "firmao-mastra-agent", instructions: "You are an AI agent with Firmao tools via Composio.", model: "openai/gpt-5", }); let messages: AiMessageType[] = []; const rl = readline.createInterface({ input: process.stdin, output: process.stdout, prompt: "> ", }); rl.prompt(); rl.on("line", async (input: string) => { const trimmed = input.trim(); if (["exit", "quit"].includes(trimmed.toLowerCase())) { rl.close(); return; } messages.push({ id: crypto.randomUUID(), role: "user", content: trimmed }); const { text } = await agent.generate(messages, { toolsets: { firmao: composioTools }, maxSteps: 8, }); if (text) { console.log(`Agent: ${text}\n`); messages.push({ id: crypto.randomUUID(), role: "assistant", content: text }); } rl.prompt(); }); rl.on("close", async () => { await mcpClient.disconnect(); process.exit(0); }); } main(); ``` ## Conclusion You've built a Mastra AI agent that can interact with Firmao through Composio's Tool Router. You can extend this further by: - Adding other toolkits like Gmail, Slack, or GitHub - Building a web-based chat interface around this agent - Using multiple MCP endpoints to enable cross-app workflows ## How to build Firmao MCP Agent with another framework - [OpenAI Agents SDK](https://composio.dev/toolkits/firmao/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/firmao/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/firmao/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/firmao/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/firmao/framework/codex) - [OpenClaw](https://composio.dev/toolkits/firmao/framework/openclaw) - [Hermes](https://composio.dev/toolkits/firmao/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/firmao/framework/cli) - [Google ADK](https://composio.dev/toolkits/firmao/framework/google-adk) - [LangChain](https://composio.dev/toolkits/firmao/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/firmao/framework/ai-sdk) - [LlamaIndex](https://composio.dev/toolkits/firmao/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/firmao/framework/crew-ai) ## Related Toolkits - [Hubspot](https://composio.dev/toolkits/hubspot) - HubSpot is an all-in-one marketing, sales, and customer service platform.

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 Mastra AI? Yes, you can. Mastra AI 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. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
