## 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 870+ other Apps for cross-app workflows. It loads the tools you need, so GPTs aren't overwhelmed by tools you don't need.

## Connect Xero to Codex

### How to install Xero 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 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_GET_CONNECTIONS` | Get Connections | Tool to list active xero connections. use when you need to retrieve all current tenant connections for the authenticated user. |
| `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_QUOTES` | Get Quotes | Tool to retrieve a list of quotes. use when you need to list, filter, or page through sales quotes. use after obtaining the tenant id via connections. |
| `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. |

## Frequently Asked Questions

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

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 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 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.
