## Introduction

### How to connect Circleback 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 Circleback account to ChatGPT Work via Composio Connect, so it can search meetings, fetch transcripts, extract action items, surface related people, and pull support docs through natural language commands without ever putting your account credentials at risk.

- [Hermes](https://composio.dev/toolkits/circleback_mcp/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 Circleback 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 Circleback 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 Circleback 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 Circleback 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

```

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

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

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `CIRCLEBACK_MCP_FIND_COMPANIES` | Findcompanies | Find companies matching the given search terms. Searches match company names and company domains. The data returned will be an array of objects with each company's domain and name when available. |
| `CIRCLEBACK_MCP_FIND_PROFILES` | Findprofiles | Find profiles matching the given names. The data returned will be an array of objects representing each of the matching profiles. |
| `CIRCLEBACK_MCP_GET_TRANSCRIPTS_FOR_MEETINGS` | Gettranscriptsformeetings | Get the full transcripts for given meeting IDs. Use string IDs like Vd6Pz_kWqLm3xY-c8RhTn. The data returned will be an array of objects, each representing a full transcript for a meeting. Each transcript object will contain the meetingId, meetingName, and an array of transcript segments. Each segment is formatted with timestamps like: {startTimestamp: 123.45, endTimestamp: 128.00, speaker: 'John Doe', words: 'This is a test.'} This should be used to get detailed transcript information for one or many meetings at once. |
| `CIRCLEBACK_MCP_LIST_TAGS` | Listtags | List all tags available in the user's workspace. Returns an array of tag objects with their IDs and names. Use this to discover available tags before filtering meetings, transcripts, or action items by tag. |
| `CIRCLEBACK_MCP_READ_MEETINGS` | Readmeetings | Given up to 50 meeting IDs, fetch detailed information for each meeting. Use string IDs like Vd6Pz_kWqLm3xY-c8RhTn. The data returned will be an array of objects, with each containing the meeting ID, name, notes, attendees, action items, AI-generated insights, creator, tags, status, duration, and creation date. |
| `CIRCLEBACK_MCP_SEARCH_ACTION_ITEMS` | Searchactionitems | Find action items that match a given search term or filter. Returns action items with their title, description, status, assignee, and related meeting details. By default, only action items assigned to the user are returned. To find action items assigned to someone else, use FindProfiles to resolve their name to a profile ID and pass it as assigneeProfileId. Action items can be filtered by search terms, status (PENDING or DONE), tags, and meeting date range (startDate/endDate). Only 25 action items are returned per page, so this function may need to be called multiple times if there are more than that many results. If 25 action items are returned, call this function again with the next pageIndex to ensure you get all results. |
| `CIRCLEBACK_MCP_SEARCH_CALENDAR_EVENTS` | Searchcalendarevents | Get calendar events from the user's connected calendars. When searching for calendar events, the tool will extract relevant excerpts based on the intent instead of returning the entire data. Each calendar event excerpt includes comprehensive details: event title, date (in the user's timezone), organizer email, attendees (with names, emails, and status), calendar description (if present), meeting platform (Zoom, Google Meet, Microsoft Teams, etc.), meeting platform link, whether it's a recurring event, Circleback join status, and any associated meeting data from the Circleback (meeting ID, status, tag IDs, user notes). You can filter events by providing a date range using startDate and endDate parameters. This is useful for finding upcoming meetings, scheduled calls, or calendar events that the user has. Note: This should be primarily used for searching calendar events happening in the future. Past calendar events have a meeting record if they were captured with Circleback. The only reason to use this to search past calendar events is if searching for the meeting with SearchMeetings yielded no relevant results. Only 50 calendar events are returned per page, so this function may need to be called multiple times if there are more than that many results. If 50 events are returned, call this function again with the next pageIndex to ensure you get all results. |
| `CIRCLEBACK_MCP_SEARCH_EMAILS` | Searchemails | Search the user's connected email accounts for email threads matching a query. This should be used when the user asks questions about their emails or needs to find specific email conversations. This function queries across all connected email services and retrieves up to 20 matching email threads per service per page. The data returned will be an array of objects, with each containing the email thread ID, subject line, and relevant excerpts. Each email thread object includes metadata such as the sender email, received date, and the fromEmailAddress of the connected account the thread belongs to (if available). Only 20 email threads are returned per page, so this function may need to be called multiple times if there are more than that many results. |
| `CIRCLEBACK_MCP_SEARCH_MEETINGS` | Searchmeetings | Find meetings that match a given search term or filter. Searches can be done by direct match on the meeting name or notes. Search term is a direct match ignoring case, prefer to search for a single word or phrase if provided. Searches can also be performed for tags or related profiles (attendees of the meetings). When searching for a meeting, the tool will find the appropriate meeting and extract the relevant source excerpt based on the intent instead of returning the entire data. NOTE: A search term is not explicitly required, for example if you want to find all meetings with a specific tag in a date range, only include those and don't pass a searchTerm. To restrict the search further, you can provide a start and end date. This will significantly improve performance. The data returned will be an an array of objects, with each containing meeting data. Only 20 meetings are returned per page, so this function may need to be called multiple times if there are more than that many results. If 20 meetings are returned, call this function again with the next pageIndex to ensure you get all results. IMPORTANT: The pageIndex is only valid for the exact same search parameters (aside from pageIndex). For example, if you provide a start / end date to fetch page 0, then you must provide the EXACT SAME start / end dates to fetch page 1. |
| `CIRCLEBACK_MCP_SEARCH_SUPPORT_ARTICLES` | Searchsupportarticles | Search for support articles about Circleback to find relevant documentation and help content. |
| `CIRCLEBACK_MCP_SEARCH_TRANSCRIPTS` | Searchtranscripts | Search meeting transcripts to find transcript chunks that match a given search term. If the user's question requires searching for multiple distinct search terms, you should call this function multiple times. The data returned will be an an array of objects, with each containing the meeting ID, name, creator user ID, when it was created, the chunk matching the search term, and the start and end timestamps of the matching chunk. Search results can be further filtered by including tags, profiles (attendees), or domains. This function is useful to find relevant meetings where a search term was mentioned. We can find more details about those meetings using the ReadMeetings tool. |

## Frequently Asked Questions

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

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

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

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