Navan is a business travel and expense platform with APIs for travel, transactions, users, and audits. It helps companies centralize travel operations, spending data, and policy controls.

26 Tools

Introduction

Claude is Anthropic's AI assistant, available on the web, in the desktop app, and on mobile. Cowork is its agent for knowledge work, and it runs on all of those surfaces too. Connected to your apps, Claude can work with your files and services to accomplish complex tasks on your behalf.

This guide walks you through the easiest and most secure way to connect your Navan account to Claude via Composio Connect, enabling it to list recent business travel transactions, review unusual employee expense activity, show users with missing custom fields, and more such actions on your behalf without compromising your account security.

Setup is the same on Claude Web, Desktop, and Cowork, and you only need to do it once. The connector is tied to your account, so it's available in all three.

3. Connect your Navan account

Back in Claude, ask it to connect to Navan or give it any Navan-related task.

For example, ask Claude to:

  • "List recent business travel transactions"
  • "Review unusual employee expense activity"
  • "Show users with missing custom fields"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in Claude, and your Navan account is ready to use.

What is the Navan Claude Connector, 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.

Troubleshooting

1. Why does Claude not use the Composio connector for Navan?

The connector can show as connected, but Claude must use it in each Navan conversation.

  • Click + at the lower left of the chat, or type /.
  • Hover Connectors.
  • Turn on Composio.
  • Ask Claude to connect to Navan again.

2. Why does Claude show an MCP server error before Navan connects?

Claude can show Couldn't reach the MCP server or Authorization with the MCP server failed when you add the connector for Navan.

  • Check that the connector URL is https://connect.composio.dev/mcp.
  • Connectors run from Anthropic's cloud, so your device network is usually not the problem.
  • Add the connector again from Customize > Connectors, then ask Claude to connect Navan.
  • If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the Navan authorization link not work?

The Composio connector is one server. Your Navan account connects separately when Claude asks for it.

  • If the browser does not open, or the link expires, ask Claude to retry the Navan connection.
  • Composio creates a fresh Navan authorization link.
  • Open that link in your browser and finish the Navan sign-in.

4. Why do Navan actions fail after they worked before?

The Navan connection can expire or lose permission.

  • Ask Claude to inspect the Navan connection.
  • If the connection is unhealthy, disconnect it when Claude prompts you.
  • Reconnect the Navan account and retry the action.
  • If Claude shows a permission prompt, approve it before Claude changes data in Navan.
  • If the action still fails with a permission error, check that the connected account has that permission in Navan itself.

5. How do I switch to a different Navan account?

Claude can manage the Navan connection for you.

  • Ask Claude to disconnect or delete the current Navan account.
  • Ask Claude to connect Navan again.
  • Open the new Composio authorization link for Navan.
  • Sign in with the other Navan account in the browser.
  • After the account connects, ask Claude to retry the Navan task.

6. Why is my Navan connection missing in Claude Desktop or on a Team plan?

The connector belongs to your Claude account, so your Navan connection works in Claude Web, Desktop, and Cowork.

  • In Claude Desktop, open Customize > Connectors.
  • Next to Composio, click ⋮ and click Clear cache.
  • If Navan tools still do not appear, click ⋮, disconnect, remove the connector, and add it again.
  • On Team or Enterprise, an Owner or Primary Owner must enable the connector before you can connect Navan.

FAQ

Frequently asked questions

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.

Yes, you can. Claude Cowork 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.

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.

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.
