# How to integrate Xero MCP with Mastra AI ```json { "title": "How to integrate Xero MCP with Mastra AI", "toolkit": "Xero", "toolkit_slug": "xero", "framework": "Mastra AI", "framework_slug": "mastra-ai", "url": "https://composio.dev/toolkits/xero/framework/mastra-ai", "markdown_url": "https://composio.dev/toolkits/xero/framework/mastra-ai.md", "updated_at": "2026-10-05T11:08:31.352Z" } ``` ## Introduction This guide walks you through connecting Xero to Mastra AI using the Composio tool router. By the end, you'll have a working Xero agent that can list all active xero tenant connections, show latest contacts added this week, retrieve all open quotes for this month through natural language commands. This guide will help you understand how to give your Mastra AI agent real control over a Xero account through Composio's Xero MCP server. Before we dive in, let's take a quick look at the key ideas and tools involved. ## Also integrate Xero with - [Claude Code](https://composio.dev/toolkits/xero/framework/claude-code) - [Cursor](https://composio.dev/toolkits/xero/framework/cursor) - [ChatGPT](https://composio.dev/toolkits/xero/framework/chatgpt) - [Claude Cowork](https://composio.dev/toolkits/xero/framework/claude-cowork) - [Antigravity](https://composio.dev/toolkits/xero/framework/antigravity) - [OpenAI Agents SDK](https://composio.dev/toolkits/xero/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/xero/framework/claude-agents-sdk) - [Codex](https://composio.dev/toolkits/xero/framework/codex) - [Kimi Code](https://composio.dev/toolkits/xero/framework/kimi) - [Grok Build](https://composio.dev/toolkits/xero/framework/grok-build) - [VS Code](https://composio.dev/toolkits/xero/framework/vscode) - [OpenCode](https://composio.dev/toolkits/xero/framework/opencode) - [OpenClaw](https://composio.dev/toolkits/xero/framework/openclaw) - [Hermes](https://composio.dev/toolkits/xero/framework/hermes-agent) - [Atomic Agent](https://composio.dev/toolkits/xero/framework/atomic-agent) - [CLI](https://composio.dev/toolkits/xero/framework/cli) - [Google ADK](https://composio.dev/toolkits/xero/framework/google-adk) - [LangChain](https://composio.dev/toolkits/xero/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/xero/framework/ai-sdk) - [LlamaIndex](https://composio.dev/toolkits/xero/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/xero/framework/crew-ai) - [Pydantic AI](https://composio.dev/toolkits/xero/framework/pydantic-ai) - [AutoGen](https://composio.dev/toolkits/xero/framework/autogen) ## 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 Xero tools - Connect Mastra's MCP client to the Composio generated MCP URL - Fetch Xero 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 Xero 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 Xero MCP server, and what's possible with it? The Xero MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Xero account. It provides structured and secure access to your accounting data, so your agent can retrieve contacts, manage connections, update invoices, and monitor quotes automatically on your behalf. - Connection management: Instantly list all active Xero tenant connections linked to your account, making it easy for your agent to select and operate on the right organization. - Contact retrieval and lookup: Fetch detailed, up-to-date lists of business contacts including filtering, paging, and incremental updates to keep your records synchronized and actionable. - Quote management and tracking: Retrieve, filter, or search through your sales quotes so your agent can help you stay on top of prospective business and follow up faster. - Invoice updating and automation: Modify details of existing invoices—such as amounts, due dates, and line items—allowing your agent to keep your invoicing accurate and up to date without manual edits. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `XERO_CREATE_BANK_TRANSACTION` | Create Bank Transaction | Create a bank transaction in Xero. Use SPEND for payments out or RECEIVE for money received. | | `XERO_CREATE_CONTACT` | Create Contact | Create a new contact in Xero. Contacts can be customers, suppliers, or both. | | `XERO_CREATE_INVOICE` | Create Invoice | Create a new invoice in Xero. Supports both sales invoices (ACCREC) and bills (ACCPAY). | | `XERO_CREATE_ITEM` | Create Item | Create an inventory item in Xero. Items can be tracked for sales and/or purchases. | | `XERO_CREATE_MANUAL_JOURNAL` | Create Manual Journal | Create one or more manual journals (journal entries) in Xero with journal lines. Manual journals must balance (debits equal credits). | | `XERO_CREATE_PAYMENT` | Create Payment | Create a payment in Xero to link an invoice with a bank account transaction. | | `XERO_CREATE_PURCHASE_ORDER` | Create Purchase Order | Create a purchase order in Xero to order goods/services from suppliers. | | `XERO_GET_ACCOUNT` | Get Account | Retrieve a specific account from Xero's chart of accounts by its unique ID. Returns detailed account information including code, name, type (BANK, REVENUE, EXPENSE, etc.), status (ACTIVE/ARCHIVED), tax settings, bank details (for BANK accounts), and classification. Use XERO_LIST_ACCOUNTS to get account IDs if you don't already have one. | | `XERO_GET_ASSET` | Get Asset | Retrieve a specific asset by ID from Xero. Returns depreciation details and book value. | | `XERO_GET_BALANCE_SHEET_REPORT` | Get Balance Sheet Report | Retrieve Balance Sheet report from Xero.

Response structure is Reports → Rows → Sections; account lines are nested inside group sections and summary totals (e.g., 'Total Current Assets') appear in SummaryRows. | | `XERO_GET_BUDGET` | Get Budget | Retrieve a budget from Xero. Budgets track planned vs actual spending by account. | | `XERO_GET_CONNECTIONS` | Get Connections | Tool to list active Xero connections. Use to retrieve all current tenant connections for the authenticated user and resolve the correct tenant_id before making data requests. When multiple tenants are returned, never assume the first connection is correct — always explicitly pass the intended tenant_id to every subsequent call. Using a wrong or stale tenant_id can silently return or modify data for a different organisation. | | `XERO_GET_CONTACTS` | Get Contacts | Tool to retrieve a list of contacts. Use when you need up-to-date contact information with filtering, paging, or incremental updates. | | `XERO_GET_INVOICE` | Get Invoice | Retrieve a specific invoice by ID from Xero.

Use after obtaining the tenant ID via connections. | | `XERO_GET_TRIAL_BALANCE_REPORT` | Get Trial Balance Report | Retrieve Trial Balance report from Xero. Shows all account balances (debits and credits) at a specific date. Use to verify that total debits equal total credits and to prepare financial statements. Credit balances appear as negative numbers in the response. | | `XERO_LIST_ACCOUNTS` | List Accounts | Retrieve chart of accounts from Xero. Returns all accounting codes used for categorizing transactions. Use AccountID (not name or code) as the unique identifier for accounts. Results may be paginated; increment the page parameter until empty results are returned to avoid missing accounts in large organisations. | | `XERO_LIST_ASSETS` | List Assets | Retrieve fixed assets from Xero. Assets track depreciation and book value of capital equipment. | | `XERO_LIST_ATTACHMENTS` | List Attachments | List all attachments for a specific entity in Xero (invoice, contact, etc.). | | `XERO_LIST_BANK_TRANSACTIONS` | List Bank Transactions | Retrieve bank transactions from Xero. Includes SPEND, RECEIVE, and transfer types; unfiltered results include DELETED transactions that skew totals. Dates returned in /Date(milliseconds_since_epoch)/ format. Rate limit: ~60 requests/minute per org; heavy pagination may trigger 429 errors. | | `XERO_LIST_CREDIT_NOTES` | List Credit Notes | Retrieve list of credit notes from Xero. Credit notes are issued to reduce amounts owed by customers. | | `XERO_LIST_FILES` | List Files | Retrieve files from Xero Files. Lists documents stored in Xero's file management system. | | `XERO_LIST_FOLDERS` | List Folders | Retrieve folders from Xero Files. Lists document folders in Xero's file management system. | | `XERO_LIST_INVOICES` | List Invoices | Retrieve a list of invoices from Xero. Results include both sales invoices (Type=ACCREC) and bills (Type=ACCPAY) by default; filter by Type in the `where` clause when only one is needed. Supports filtering by status, contact, date range, and pagination. | | `XERO_LIST_ITEMS` | List Items | Retrieve items (inventory/products) from Xero. Items can be tracked for sales and/or purchases. | | `XERO_LIST_JOURNALS` | List Journals | Retrieve journals from Xero. Journals show the accounting entries for all transactions. Omitting filters returns the full historical journal ledger and can produce very large responses — use If-Modified-Since and/or paymentsOnly to narrow scope. No date range filter parameter exists. Results are returned inside a Journals array field. | | `XERO_LIST_MANUAL_JOURNALS` | List Manual Journals | Retrieve manual journals from Xero. Manual journals are used for period-end adjustments and corrections. | | `XERO_LIST_PAYMENTS` | List Payments | Retrieve list of payments from Xero. Payments link invoices to bank transactions; invoices may have multiple partial/split payment records. Response Date fields use Xero's /Date(milliseconds)/ format requiring custom parsing. | | `XERO_LIST_PROJECTS` | List Projects | Retrieve projects from Xero. Projects track time and costs for client work. | | `XERO_LIST_PURCHASE_ORDERS` | List Purchase Orders | Retrieve list of purchase orders from Xero. Purchase orders track goods/services ordered from suppliers. | | `XERO_LIST_TAX_RATES` | List Tax Rates | Retrieve tax rates from Xero. Shows available tax codes and rates for the organization. Use returned tax codes as valid `TaxType` values in other tools — invalid values cause ValidationException errors. | | `XERO_LIST_TRACKING_CATEGORIES` | List Tracking Categories | Retrieve tracking categories from Xero. Tracking categories are used to segment data for reporting (e.g., departments, regions). | | `XERO_POST_INVOICE_UPDATE` | Update Invoice | Tool to update an existing invoice. Use when you need to modify the details of an invoice after it's been created. | | `XERO_UPDATE_CONTACT` | Update Contact | Update an existing contact in Xero. Only provided fields will be updated. | | `XERO_UPLOAD_ATTACHMENT` | Upload Attachment | Upload a file attachment to a Xero entity (invoice, contact, etc.). Supports PDF, images, and documents. | ## Supported Triggers None listed. ## Creating MCP Server - Stand-alone vs Composio SDK The Xero MCP server is an implementation of the Model Context Protocol that connects your AI agent to Xero. It provides structured and secure access so your agent can perform Xero 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 Xero 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 Xero What's happening: - create spins up a short-lived MCP HTTP endpoint for this user - The toolkits array contains "xero" for Xero 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: ["xero"], }, ); const composioMCPUrl = session.mcp.url; console.log("Xero 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 Xero 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: "xero-mastra-agent", instructions: "You are an AI agent with Xero 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 Xero 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: { xero: 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: ["xero"], }); const composioMCPUrl = session.mcp.url; const mcpClient = new MCPClient({ id: composioUserID as string, servers: { xero: { url: new URL(composioMCPUrl), requestInit: { headers: session.mcp.headers, }, }, }, timeout: 30_000, }); const composioTools = await mcpClient.getTools(); const agent = new Agent({ name: "xero-mastra-agent", instructions: "You are an AI agent with Xero 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: { xero: 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 Xero 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 Xero MCP Agent with another framework - [Claude Code](https://composio.dev/toolkits/xero/framework/claude-code) - [Cursor](https://composio.dev/toolkits/xero/framework/cursor) - [ChatGPT](https://composio.dev/toolkits/xero/framework/chatgpt) - [Claude Cowork](https://composio.dev/toolkits/xero/framework/claude-cowork) - [Antigravity](https://composio.dev/toolkits/xero/framework/antigravity) - [OpenAI Agents SDK](https://composio.dev/toolkits/xero/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/xero/framework/claude-agents-sdk) - [Codex](https://composio.dev/toolkits/xero/framework/codex) - [Kimi Code](https://composio.dev/toolkits/xero/framework/kimi) - [Grok Build](https://composio.dev/toolkits/xero/framework/grok-build) - [VS Code](https://composio.dev/toolkits/xero/framework/vscode) - [OpenCode](https://composio.dev/toolkits/xero/framework/opencode) - [OpenClaw](https://composio.dev/toolkits/xero/framework/openclaw) - [Hermes](https://composio.dev/toolkits/xero/framework/hermes-agent) - [Atomic Agent](https://composio.dev/toolkits/xero/framework/atomic-agent) - [CLI](https://composio.dev/toolkits/xero/framework/cli) - [Google ADK](https://composio.dev/toolkits/xero/framework/google-adk) - [LangChain](https://composio.dev/toolkits/xero/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/xero/framework/ai-sdk) - [LlamaIndex](https://composio.dev/toolkits/xero/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/xero/framework/crew-ai) - [Pydantic AI](https://composio.dev/toolkits/xero/framework/pydantic-ai) - [AutoGen](https://composio.dev/toolkits/xero/framework/autogen) ## Related Toolkits - [Stripe](https://composio.dev/toolkits/stripe) - Stripe is a global online payments platform offering APIs for managing payments, customers, and subscriptions.

With a standalone Xero MCP server, the agents and LLMs can only access a fixed set of Xero tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Xero 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 Xero tools. ### Can I manage the permissions and scopes for Xero while using Tool Router? Yes, absolutely. You can configure which Xero 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 Xero data and credentials are handled as safely as possible. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
