## Introduction

### How to connect ContactOut 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 ContactOut account to ChatGPT Work via Composio Connect, so it can discover contacts, enrich profiles, verify emails, manage outreach campaigns, and generate usage reports through natural language commands without ever putting your account credentials at risk.

## Also integrate ContactOut with

- [Hermes](https://composio.dev/toolkits/contactout/framework/hermes-agent)

## TL;DR

### Why use Composio over default connectors?
- Apps with read and write access. Default connectors mostly can read your data. Composio's ContactOut integration lets ChatGPT Work take actions like creating drafts, sending updates, labeling records, and more.
- 1,500+ 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 ContactOut 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 ContactOut 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 ContactOut 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:

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

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

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

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `CONTACTOUT_ADD_CAMPAIGN_RECIPIENTS` | Add Campaign Recipients | Add 1-100 recipients to an existing campaign. This consequential write immediately changes the campaign's recipient set and may lead to outreach when the campaign is active. A successful request can still contain failed recipients, so inspect every result and both counts. Production Campaigns entitlement and mutation behavior are not live-verified. |
| `CONTACTOUT_CHECK_LINKEDIN_CONTACT_AVAILABILITY` | Check LinkedIn Contact Availability | Check whether a LinkedIn profile has a personal email, work email, or phone without revealing it or consuming credits. Requires a paid ContactOut production entitlement. |
| `CONTACTOUT_COUNT_PEOPLE` | Count People | Estimate matching people and available personal emails, work emails, and phones from substantive People Search filters without consuming credits. This endpoint requires a paid ContactOut production entitlement; sandbox sample access does not confirm production access. |
| `CONTACTOUT_CREATE_BULK_EMAIL_VERIFICATION_JOB` | Create Bulk Email Verification Job | Queue asynchronous deliverability verification for 1-100 email addresses, optionally delivering results to an HTTP or HTTPS callback URL; may consume verifier credits. |
| `CONTACTOUT_CREATE_LINKEDIN_CONTACT_INFO_BATCH_JOB` | Create LinkedIn Contact Info Batch Job | Queue asynchronous contact discovery for 1-1000 LinkedIn profiles, optionally delivering results to a callback URL; may consume credits per profile. |
| `CONTACTOUT_ENRICH_COMPANIES_BY_DOMAIN` | Enrich Companies by Domain | Return company profiles for 1-30 domains; each found company consumes a search credit. |
| `CONTACTOUT_ENRICH_LINKEDIN_PROFILE` | Enrich LinkedIn Profile | Return a professional profile for a regular LinkedIn profile URL, optionally including contact data; may consume search, email, and phone credits. |
| `CONTACTOUT_ENRICH_PERSON` | Enrich Person | Find and enrich one person using a LinkedIn URL, email, or phone; alternatively, provide a name plus employer, education, location, or job-title evidence. May consume search and requested contact-data credits. |
| `CONTACTOUT_ENRICH_PERSON_BY_EMAIL` | Enrich Person by Email | Return a professional profile matched from an email address, optionally requesting real-time work-email verification. A successful match may consume email and phone credits. |
| `CONTACTOUT_FIND_LINKEDIN_PROFILE_BY_EMAIL` | Find LinkedIn Profile by Email | Resolve an email address to its matching LinkedIn profile URL. A successful match consumes one email credit. |
| `CONTACTOUT_GET_API_USAGE_STATS` | Get API Usage Stats | Return ContactOut API credit usage and quotas for a billing month. Remaining and over-quota fields are available for postpaid accounts, while prepaid accounts report remaining balances in quota fields. ContactOut sandbox responses contain fixed illustrative samples; never present those values as the connected account's real balances. |
| `CONTACTOUT_GET_BULK_EMAIL_VERIFICATION_JOB` | Get Bulk Email Verification Job | Get the status and available per-email results of an asynchronous bulk email-verification job. |
| `CONTACTOUT_GET_CAMPAIGN` | Get Campaign | Return one campaign's sequence steps and optionally its performance statistics. Production Campaigns entitlement depends on the connected ContactOut account. |
| `CONTACTOUT_GET_HASHED_EMAIL_IDENTIFIERS` | Get Hashed Email Identifiers | Return unordered SHA-256 hashes of normalized personal emails found for 5-100 distinct LinkedIn profiles. Hashes are not mapped back to profiles and may consume email credits. |
| `CONTACTOUT_GET_LINKEDIN_CONTACT_INFO` | Get LinkedIn Contact Info | Reveal email and optionally phone contact information for one regular LinkedIn profile URL; consumes credits when data is found. |
| `CONTACTOUT_GET_LINKEDIN_CONTACT_INFO_BATCH` | Get LinkedIn Contact Info Batch | Synchronously reveal contact information for 1-100 LinkedIn profiles; may consume email and phone credits per profile. |
| `CONTACTOUT_GET_LINKEDIN_CONTACT_INFO_BATCH_JOB` | Get LinkedIn Contact Info Batch Job | Get the status and available results of an asynchronous LinkedIn contact-info batch job. |
| `CONTACTOUT_LIST_CAMPAIGNS` | List Campaigns | Return one page of email campaigns and their lifecycle statuses. Production Campaigns entitlement is unverified; the connected API token may require additional ContactOut plan access. |
| `CONTACTOUT_LIST_DECISION_MAKERS` | List Decision Makers | Return one page of key decision makers for the best-matching company. For the first page, provide a company LinkedIn URL, domain, or name. Returned profiles consume search credits; reveal_info may also consume email and phone credits. |
| `CONTACTOUT_REMOVE_CAMPAIGN_RECIPIENTS` | Remove Campaign Recipients | Destructively remove 1-100 recipients from an existing campaign by email. The request can partially succeed, so inspect every result and both counts. Production Campaigns entitlement and this mutation remain unverified without an isolated campaign fixture. |
| `CONTACTOUT_SEARCH_COMPANIES` | Search Companies | Return one page of companies matching identity, size, location, industry, technology, revenue, or founding-year filters. Each returned company consumes a search credit. |
| `CONTACTOUT_SEARCH_PEOPLE` | Search People | Return one page of professional profiles matching person, role, employer, education, location, and contact-availability filters. Returned profiles consume search credits; reveal_info may also consume email and phone credits. |
| `CONTACTOUT_START_CAMPAIGN` | Start Campaign | Start a draft ContactOut campaign or resume a stopped campaign. This can immediately begin sending real outreach to the campaign's recipients and is an irreversible external side effect; confirm the campaign ID and intent before calling. Calling it for an already-active campaign is an idempotent success. Production Campaigns entitlement depends on the connected account. |
| `CONTACTOUT_STOP_CAMPAIGN` | Stop Campaign | Stop a running ContactOut campaign, interrupting its outreach. This is a consequential lifecycle change; use only with an explicitly selected active campaign. Repeating the request for an already-stopped campaign is treated as an idempotent success when ContactOut returns success. |
| `CONTACTOUT_VERIFY_EMAIL` | Verify Email | Check one email address for valid, invalid, accept-all, disposable, or unknown deliverability. A valid, invalid, or accept-all result may consume one verifier credit. |

## Frequently Asked Questions

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

With a standalone ContactOut MCP server, the agents and LLMs can only access a fixed set of ContactOut tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from ContactOut 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 ContactOut tools.

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

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