## Introduction

### How to connect Coresignal 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 Coresignal account to ChatGPT Work via Composio Connect, so it can find engineers at fast growing startups, research employee counts for target accounts, source sales leaders in fintech companies 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 Coresignal 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 Coresignal 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 Coresignal 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 Coresignal 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 Coresignal MCP server, and what's possible with it?

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

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `CORESIGNAL_GET_REAL_TIME_EMPLOYEE_PROFILE` | Get Real-Time Employee Profile | Retrieve an employee profile, using cached data up to max_age hours old (24 by default); set max_age=0 to request current data. Requires the connected account's separate Real-time Employee API entitlement and may take up to 30 seconds. |
| `CORESIGNAL_SEARCH_FAST` | Fast Search | Turn a natural-language employee, company, or job search into an Elasticsearch query, or return matching preview records. Prefer this lower-cost search unless deeper reasoning or clarification is needed; each call consumes Coresignal credits. |
| `CORESIGNAL_SEARCH_WITH_REASONING` | Search With Reasoning | Run a higher-cost natural-language search that explains its interpretation and can request clarification. Use when fast search is ambiguous or reasoning is valuable; a query-mode call consumed 100 trial credits in testing, data-mode cost varies, clarification requests do not consume credits, and the endpoint is limited to 10 requests per hour. |

## Frequently Asked Questions

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

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

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

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