Get the full transcripts for given meeting IDs. 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.

Parameters (2 required)
Required
intentstring

The reason why this tool call is being done. This intent is likely to be either the user's original question or the reason to investigate further based on their question.

meetingIdsarray

Array of meeting IDs to get transcripts for (max 50).

Read Meetings

ReadMeetings
Full Description

Given up to 100 meeting IDs, fetch detailed information for each meeting. 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.

Parameters (2 required)
Required
intentstring

The reason why this tool call is being done. This intent is likely to be either the user's original question or the reason to investigate further based on their question.

meetingIdsarray

The meeting IDs to get more information about.

Search Calendar Events

SearchCalendarEvents
Full Description

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.

Parameters (2 required, 2 optional)
Required
intentstring

The reason why this tool call is being done. This intent is likely to be either the user's original question or the reason to investigate further based on their question.

pageIndexnumber

The page index to fetch. Always start with page 0.

Optional
endDatestring

Optional ISO date string (yyyy-MM-dd) for latest date to include results from.

startDatestring

Optional ISO date string (yyyy-MM-dd) for earliest date to include results from.

Search Emails

SearchEmails
Full Description

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 associated calendar ID (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.

Parameters (2 required, 1 optional)
Required
intentstring

The reason why this tool call is being done. This intent is likely to be either the user's original question or the reason to investigate further based on their question.

searchTermstring

A query string to find relevant email threads. Supports search terms and the following filters: - from:email (sender address) or from:me (will search for emails sent by the user) - to:email (recipient address) - participant:email (matches from OR to, prefer using participant for broader search) - before:date (latest date to include results from, in yyyy-MM-dd format) - after:date (earliest date to include results from, in yyyy-MM-dd format) Examples: "Meeting participant:ali@gmail.com", "Q4 report participant:team@company.com", "project update to:sarah@company.com after:2025-04-19", "participant:company.com"

Optional
pageIndexnumber

The page index to fetch. Always start with page 0.

Search Meetings

SearchMeetings
Full Description

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. 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. If 20 meetings are returned, call this function again with the next pageIndex to ensure you get all results.

SearchTranscripts
Full Description

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.
