## Introduction

### How to integrate Viator MCP with ChatGPT Work
[ChatGPT Work](https://openai.com/chatgpt-work/) is an agent inside ChatGPT built for your most ambitious work. It takes action across your apps and files, stays with a project for hours, and turns 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 Viator account to ChatGPT Work via Composio Connect, so it can find paris food tours this weekend, compare rome colosseum skip-the-line experiences, book snorkeling activities in cancun through natural language commands without ever putting your account credentials at risk.

## TL;DR

### Why use Composio over default connectors?
- Apps with read and write access. Default connectors mostly can read your data. Composio's Viator integration lets ChatGPT Work take actions like creating drafts, sending updates, labeling records, and more.
- 1,000+ 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 Viator MCP to ChatGPT Work

### Prerequisites
- A ChatGPT account with access to ChatGPT Work (rolling out across Pro, Enterprise, Edu, Plus, and Business plans). We will use the [ChatGPT desktop app](https://openai.com/chatgpt/download/), which is available on every plan.
- Access to the Viator workspace you want to connect.
- [Composio MCP](https://dashboard.composio.dev/login?utm_source=toolkits&utm_medium=framework_template&utm_campaign=chatgpt&utm_content=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 Viator to ChatGPT Work
### 1. Open the MCP settings
In ChatGPT Work, 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:

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

The Viator MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Viator account. It provides structured and secure access so your agent can perform Viator operations on your behalf.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `VIATOR_MCP_GET_EXPERIENCE_DETAILS` | Get experience details | Retrieves enriched information for a specific Viator experience, including detailed descriptions, highlights, imagery, pricing, duration, key features, and the click-out URL.The model should call this tool only when the user clearly refers to a specific experience—either by selecting it in the UI or by asking follow-up questions such as “Tell me more about…”;if multiple experiences were shown, the model must resolve ambiguity by asking which one the user means. This tool is intended for deepening experience understanding rather than search, and should only be invoked with a code previously returned by search_experiences. |
| `VIATOR_MCP_SEARCH_EXPERIENCES` | Search experiences | Retrieves a curated list of Viator experiences based on a free-text search of what the user wants (destination, activity type, and preferences), plus trip dates and optional refiners (budget, duration, etc.). The model must supply a non-blank searchTerm as natural language describing where and what the user is looking for (e.g. "walking tours in Paris, France", "kid friendly food experiences in Rome"). Dates, prices, duration limits, and currency belong in their dedicated parameters—not inside searchTerm. The model must provide searchTerm and dates before calling this tool. The model may re-issue a refined searchExperiences call whenever the user adds, removes, or adjusts refinement criteria (e.g., kid-friendly, price range, shorter duration) to narrow or improve the results. If the tool returns zero results, the model must proactively guide the user toward a successful refinement. It should review the parameters used in the failed request and recommend the most appropriate based on the proposed logic:" If > 1 categories applied, suggest removing some categories. Eg: “It looks like those categories combined are too restrictive. Would you like to narrow it down?” If the query requests a specific feature (eg private tour), suggest removing this constraint. Eg: “Private tours may be limited in this area, would you like to consider group options too?” If duration (avg from/to) > XX, suggest trying a shorter duration. If duration (avg from/to) < XX, suggest trying a longer duration. If price constraint was applied, suggest widening (or removing) price limits. Else, suggest broaden location search. Eg: “Nothing matches in central Siena, should we try Tuscany or nearby towns?” |

## Frequently Asked Questions

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

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

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

Yes, you can. ChatGPT Work 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 Viator tools.

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

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