## Introduction

### How to connect Navan MCP with ChatGPT
[ChatGPT](https://chatgpt.com/) can take action across your apps and files, stay with a project for hours, and turn a goal into finished materials like sheets, slides, and docs, not just answers.
In this guide, I will explain the easiest and most secure way to connect your Navan account to ChatGPT via Composio Connect, so it can review business travel, query transactions, manage users, inspect audits, and use custom fields through natural language commands without ever putting your account credentials at risk.

## Also integrate Navan with

- [Claude Cowork](https://composio.dev/toolkits/navan/framework/claude-cowork)
- [Hermes](https://composio.dev/toolkits/navan/framework/hermes-agent)
- [Atomic Agent](https://composio.dev/toolkits/navan/framework/atomic-agent)

## TL;DR

### Why use Composio over default connectors?
- Apps with read and write access. Default connectors mostly can read your data. Composio's Navan integration lets ChatGPT take actions like creating drafts, sending updates, labeling records, and more.
- 1,700+ SaaS toolkits out of the box. Composio gives you instant access to a vast catalog of pre-built connectors, from Gmail and Slack to Notion, Linear, and Salesforce.
- One MCP server for every app. Connect any of your applications on demand through a single endpoint, rather than juggling a separate server for each app.
- Smart, context-aware tool loading. Unlike traditional MCP servers that dump every available tool into the LLM context window, Composio searches for and loads only the tools relevant to the task at hand.
- Cross-app automation. Chain actions across multiple apps in a single run - fetch a thread, summarize it in Notion, and post highlights to Slack without leaving the conversation.

## Connect Navan to ChatGPT

### Prerequisites
- A ChatGPT account. We will use the [ChatGPT desktop app](https://openai.com/chatgpt/download/), and the steps are the same on the web.
- Access to the Navan workspace you want to connect.
- [Composio plugin](https://dashboard.composio.dev/login?cta_placement=toolkit-framework-chatgpt-composio-connect&next=%2F~%2Forg%2Fconnect%2Fclients%2Fchatgpt).
Note: Composio connects through OAuth. You will be asked to sign in and approve specific permissions. Review the permission screen carefully if you are using a work account.
### Step-by-step: Connect Navan to ChatGPT
### 1. Install the Composio plugin
Click the button. ChatGPT opens the Composio plugin page. Click Install plugin.
[Install in ChatGPT](https://chatgpt.com/plugins/plugin_asdk_app_6a58503580c08191b78cc5bdaf4eba6e)
You can also find it inside ChatGPT: go to Settings, open Plugins, search the marketplace for Composio, and click Install plugin.
### 2. Authenticate
After you install, ChatGPT asks you to authenticate with Composio. Log in and click Allow access to authorize ChatGPT to use your Composio account.
### 3. Start using Composio
That is it. Composio tools are now available in ChatGPT. Type @Composio followed by your request, for example @Composio find unread Navan messages and summarize them, and it will run the actions you authorize. On first use it asks you to authorize Navan.
### Option 2: Add Composio as an MCP server
If you cannot use the plugin marketplace, add Composio as a custom MCP server instead.
### 1. Open the MCP settings
In ChatGPT, go to Settings and open the Plugins section. Inside the Plugins page, click the MCP tab.
### 2. Add the server
Click Add server. In the Name field enter Composio, for Type select Streamable HTTP, and in the URL field paste the Composio MCP server URL:

```bash
https://connect.composio.dev/mcp
```

## What is the Navan MCP server, and what's possible with it?

The Navan MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Navan account. It provides structured and secure access to business travel, booking, expense, transaction, user, receipt, audit, and custom-field data, so your agent can review travel and expenses, retrieve receipts, update transactions, import trips, and inspect company activity on your behalf.
- Travel and booking management: Have your agent review company bookings with trip, status, type, and time filters, or import an external trip with its flight, hotel, rail, car, or black-car bookings.
- Expense and transaction tracking: Let the agent find card, manual, connect, repayment, adjustment, fee, rebate, dispute, and statement payment records, then update supported accounting, HR, and custom-field values.
- Receipt retrieval: Direct your agent to find transaction receipts and retrieve receipt, electronic-receipt, or missing-receipt affidavit links for expense records.
- Employee and company data: Instruct your agent to look up Expense users and TMC users, review custom-field definitions, and check the status of custom-field option changes.
- Audit and transaction activity: Have your agent review company audit events and inspect the activity history for individual transactions.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `NAVAN_DOWNLOAD_TRANSACTION_RECEIPT` | Download Transaction Receipt | Download a transaction receipt, electronic receipt, or missing-receipt affidavit. Navan redirects to a five-minute presigned URL; the redirect is followed immediately and the final PDF, JPEG, or PNG is returned as a file. |
| `NAVAN_GET_CUSTOM_FIELD` | Get Custom Field | Get one company Navan Expense custom-field definition by its provider field name. Use the custom-field name, such as customField1 or projects, rather than the field's display label. |
| `NAVAN_GET_CUSTOM_FIELD_JOB` | Get Custom Field Job | Get the current status, operation counts, timestamps, and up to 50 errors for an asynchronous Navan custom-field option job. |
| `NAVAN_GET_EXPENSE_USER` | Get Expense User | Get one eligible-company Navan Expense user by ID. Site-admin users are not returned and produce a not-found response. |
| `NAVAN_GET_TRANSACTION` | Get Transaction | Get one Navan Expense transaction by its ID for an ad-hoc lookup. The response preserves the concrete _type discriminator and provider-specific fields. Use the generic bulk-by-ID transaction action instead of repeatedly calling this action for a list of IDs. |
| `NAVAN_GET_TRANSACTION_RECEIPT_LINKS` | Get Transaction Receipt Links | Return seven-day presigned receipt, electronic-receipt, and affidavit URLs for one Navan Expense transaction. This endpoint returns JSON links and does not follow the separate receipt-download redirect. |
| `NAVAN_IMPORT_TRIP` | Import Trip | Import an external trip and any supplied flight, hotel, rail, car, or black-car bookings into Navan. |
| `NAVAN_LIST_ADJUSTMENTS` | List Adjustments | Return one cursor page of credit and debit adjustments for a documented date search and optional filters. Navan documents at least one single-date filter or matching date range for normal search. Dates are YYYY-MM-DD UTC, cannot precede the first day of the month two months before the current month, and ranges may not exceed 93 days. |
| `NAVAN_LIST_AUDIT_LOGS` | List Audit Logs | Return one cursor page of ERP and accounting-settings audit events for eligible companies within a required RFC3339 window of at most 31 days. |
| `NAVAN_LIST_BOOKINGS` | List Bookings | Return one page of company booking rows filtered by booking, trip, status, type, or epoch-second time ranges, optionally including transactions. |
| `NAVAN_LIST_CARD_TRANSACTIONS` | List Card Transactions | Return one cursor page of Navan card transactions for a documented date search and optional transaction filters. At least one date filter is required; dates use YYYY-MM-DD UTC, the earliest allowed date is the first day of the month two months before the current month, and ranges may span at most 93 days. |
| `NAVAN_LIST_CONNECT_TRANSACTIONS` | List Connect Transactions | Return one cursor page of external card-integration transactions. At least one single-date or date-range filter is required; dates use YYYY-MM-DD UTC, must be within Navan's documented lookback, and ranges cannot exceed 93 days. |
| `NAVAN_LIST_CUSTOM_FIELDS` | List Custom Fields | List all Navan Expense custom-field definitions for the company. |
| `NAVAN_LIST_DAILY_REBATES` | List Daily Rebates | Return one cursor page of daily rebates for a required documented date search and optional transaction filters. |
| `NAVAN_LIST_DISPUTES` | List Disputes | Return one cursor page of Navan disputes, including provisional credits and reversals for EUR and GBP, for a required documented date search and optional transaction filters. |
| `NAVAN_LIST_EXPENSE_USERS` | List Expense Users | Return one cursor page of company Expense users filtered by text, enabled state, guest state, or administrator role. This endpoint is available only to eligible companies and excludes site-admin users. |
| `NAVAN_LIST_FEES` | List Fees | Return one cursor page of direct-reimbursement, foreign-exchange, and platform fees. Navan requires at least one single-date filter or date-range bound; dates are UTC YYYY-MM-DD, cannot precede the first day of the month two months before the current month, and complete ranges may not exceed 93 days. |
| `NAVAN_LIST_MANUAL_TRANSACTIONS` | List Manual Transactions | Return one cursor page of manual expenses, reimbursements, and payroll transactions. Navan requires at least one single-date filter or matching date range for normal search; dates are UTC YYYY-MM-DD, cannot precede the first day of the month two months before the current month, and ranges may not exceed 93 days. Parameter combinations remain permissive so Navan can apply its documented contract. |
| `NAVAN_LIST_REPAYMENTS` | List Repayments | Return one cursor page of user repayments for a required documented date search and optional transaction filters. |
| `NAVAN_LIST_STATEMENT_PAYMENTS` | List Statement Payments | Return one cursor page of statement payments and statement payment refunds for a required documented date search. Use activity_type to distinguish Statement Payment from Statement Payment Refund records. |
| `NAVAN_LIST_TMC_USERS` | List TMC Users | Return one documented page of TMC company users. |
| `NAVAN_LIST_TRANSACTION_ACTIVITIES` | List Transaction Activities | Return one cursor page of activity history for a single Navan Expense transaction, newest first. The transaction must belong to the connected company; optionally filter to public or administrator-private activity. This endpoint is available only to eligible companies. |
| `NAVAN_LIST_TRANSACTION_RECEIPTS` | List Transaction Receipts | Return one cursor page of receipt links for selected Navan transaction families and a documented date search. Transactions without receipts are included with null links; returned presigned URLs should not be cached. |
| `NAVAN_LIST_TRANSACTIONS` | List Transactions | Return one cursor page across selected Navan transaction families, or fetch a batch using repeated transaction IDs. Normal search requires transaction types and at least one documented date filter. Bulk-ID mode does not require type or date; Navan does not specify that they must be absent, so combinations are passed through. |
| `NAVAN_SUBMIT_CUSTOM_FIELD_OPTION_OPERATIONS` | Submit Custom Field Option Operations | Submit 1 to 5,000 CREATE, UPDATE, UPSERT, or DELETE operations for one Navan custom field as an asynchronous job. This action can delete options; poll the returned job ID to determine completion. |
| `NAVAN_UPDATE_TRANSACTIONS` | Update Transactions | Update supported ERP, accounting, HR, and custom-field values for 1 to 100 Navan transactions. Navan processes each item independently, so a successful HTTP response can contain both successful and failed item outcomes. Updated transaction data may take up to four hours to appear in GET results. |

## Frequently Asked Questions

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

With a standalone Navan MCP server, the agents and LLMs can only access a fixed set of Navan tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Navan and many other apps based on the task at hand, all through a single MCP endpoint.

### Can I use Tool Router MCP with ChatGPT?

Yes, you can. ChatGPT 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 Navan tools.

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

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