Microsoft Teams

Microsoft Teams Toolkit

The Microsoft Teams toolkit provides Arcade LLM tools for interacting with Microsoft Teams via the Microsoft Graph API, enabling agents to read and send messages, manage chats and channels, and look up users and teams.

Capabilities

Messaging — chats: Create chats, retrieve chat metadata and messages, send messages, and reply to messages in one-on-one or group chats; addressable by chat ID or user names/IDs.
Messaging — channels: Retrieve channel messages and their replies, send messages to channels, and reply to channel messages; addressable by channel ID or name.
Chat & channel discovery: List all chats the current user belongs to, list channels within a team (including shared incoming channels), and search for channels by name.
Team & member management: List teams the user belongs to, retrieve team metadata, list or search team members (up to 999 per Graph API limit), and list all tenant users.
User & people search: Search users within the signed-in user's tenant (SearchUsers), search people the user has previously interacted with across Microsoft 365 — including external tenants (SearchPeople), and retrieve the currently signed-in user's profile.
Cross-scope search: Search messages across chats and channels tenant-wide (note: Graph API search is not strongly consistent; very recent messages may be absent).

OAuth

This toolkit uses OAuth 2.0 via Microsoft (Entra ID / Azure AD). See the Arcade Microsoft auth provider docs for setup details, required permissions, and configuration.

	Tool name	Description	Secrets
	MicrosoftTeams.CreateChat	Creates a Microsoft Teams chat. If the chat already exists with the specified members, the MS Graph API will return the existing chat. Provide any combination of user_ids and/or user_names. When available, prefer providing user_ids for optimal performance.
	MicrosoftTeams.GetChannelMessageReplies	Retrieves the replies to a Microsoft Teams channel message.
	MicrosoftTeams.GetChannelMessages	Retrieves the messages in a Microsoft Teams channel. The Microsoft Graph API does not support pagination for this endpoint.
	MicrosoftTeams.GetChannelMetadata	Retrieves metadata about a Microsoft Teams channel and its members. Provide either a channel_id or channel_name, not both. When available, prefer providing a channel_id for optimal performance. The Microsoft Graph API returns only up to the first 999 members in the channel. This tool does not return messages exchanged in the channel. To retrieve channel messages, use the `Teams.GetChannelMessages` tool. It is not necessary to call `Teams.ListTeams` before calling this tool. If the user does not provide a team_id_or_name, the tool will try to find a unique team to use.
	MicrosoftTeams.GetChatMessageById	Retrieves a Microsoft Teams chat message.
	MicrosoftTeams.GetChatMessages	Retrieves messages from a Microsoft Teams chat (individual or group). Provide one of chat_id OR any combination of user_ids and/or user_names. When available, prefer providing a chat_id or user_ids for optimal performance. If the user provides user name(s), DO NOT CALL THE `Teams.SearchUsers` or `Teams.SearchPeople` tools first. Instead, provide the user name(s) directly to this tool through the `user_names` argument. It is not necessary to provide the currently signed in user's name/id, so do not call `Teams.GetSignedInUser` before calling this tool. Messages will be sorted in descending order by the messages' `created_datetime` field. The Microsoft Teams API does not support pagination for this tool.
	MicrosoftTeams.GetChatMetadata	Retrieves metadata about a Microsoft Teams chat. Provide exactly one of chat_id or user_ids/user_names. When available, prefer providing a chat_id or user_ids for optimal performance. If multiple roup chats exist with those exact members, returns the most recently updated one. Max 20 DIFFERENT users can be provided in user_ids/user_names. This tool DOES NOT return messages in a chat. Use the `Teams.GetChatMessages` tool to get chat messages.
	MicrosoftTeams.GetSignedInUser	Get the user currently signed in Microsoft Teams. This tool is not necessary to call before calling other tools.
	MicrosoftTeams.GetTeam	Retrieves metadata about a team in Microsoft Teams. Provide one of team_id OR team_name, never both. When available, prefer providing a team_id for optimal performance. If team_id nor team_name are provided: 1) if the user has a single team, the tool will retrieve it; 2) if the user has multiple teams, an error will be returned with a list of all teams to pick from.
	MicrosoftTeams.ListChannels	Lists channels in Microsoft Teams (including shared incoming channels). This tool does not return messages nor members in the channels. To retrieve channel messages, use the `Teams.GetChannelMessages` tool. To retrieve channel members, use the `Teams.ListChannelMembers` tool.
	MicrosoftTeams.ListChats	List the Microsoft Teams chats to which the current user is a member of.
	MicrosoftTeams.ListTeamMembers	Lists the members of a team in Microsoft Teams. Provide one of team_id OR team_name, never both. When available, prefer providing a team_id for optimal performance. If team_id nor team_name are provided: 1) if the user has a single team, the tool will use it; 2) if the user has multiple teams, an error will be returned with a list of all teams to pick from. The Microsoft Graph API returns only up to the first 999 members.
	MicrosoftTeams.ListTeams	Lists the teams the current user is associated with in Microsoft Teams.
	MicrosoftTeams.ListUsers	Lists the users in the Microsoft Teams tenant. The Microsoft Graph API returns only up to the first 999 users.
	MicrosoftTeams.ReplyToChannelMessage	Sends a reply to a Microsoft Teams channel message. When available, prefer providing a channel_id for optimal performance. It is not necessary to call `Teams.ListTeams` before calling this tool. If the user does not provide a team_id_or_name, the tool will try to find a unique team to use.
	MicrosoftTeams.ReplyToChatMessage	Sends a reply to a Microsoft Teams chat message. Provide exactly one of chat_id or user_ids/user_names. When available, prefer providing a chat_id or user_ids for optimal performance. If the user provides user name(s), DO NOT CALL THE `Teams.SearchUsers` or `Teams.SearchPeople` tools first. Instead, provide the user name(s) directly to this tool through the `user_names` argument. It is not necessary to provide the currently signed in user's name/id, so do not call `Teams.GetSignedInUser` before calling this tool either.
	MicrosoftTeams.SearchChannels	Searches for channels in a given Microsoft Teams team.
	MicrosoftTeams.SearchMessages	Searches for messages across Microsoft Teams chats and channels. Note: the Microsoft Graph API search is not strongly consistent. Recent messages may not be included in search results.
	MicrosoftTeams.SearchPeople	Searches for people the user has interacted with in Microsoft Teams and other 365 products. This tool only returns users that the currently signed in user has interacted with. It may also include people that are part of external tenants/organizations. If you need to retrieve users that may not have interacted with the current user and/or that are exclusively part of the same tenant, use the `Teams.SearchUsers` tool instead.
	MicrosoftTeams.SearchTeamMembers	Searches for members of a team in Microsoft Teams. Provide one of team_id OR team_name, never both. When available, prefer providing a team_id for optimal performance. If team_id nor team_name are provided: 1) if the user has a single team, the tool will use it; 2) if the user has multiple teams, an error will be raised with a list of available teams to pick from. The Microsoft Graph API returns only up to the first 999 members of a team.
	MicrosoftTeams.SearchTeams	Searches for teams available to the current user in Microsoft Teams.
	MicrosoftTeams.SearchUsers	Searches for users in the Microsoft Teams tenant. This tool only return users that are directly linked to the tenant the current signed in user is a member of. If you need to retrieve users that have interacted with the current user but are from external tenants/organizations, use `Teams.SearchPeople`, instead. The Microsoft Graph API returns only up to the first 999 users.
	MicrosoftTeams.SendMessageToChannel	Sends a message to a Microsoft Teams channel. When available, prefer providing a channel_id for optimal performance. It is not necessary to call `Teams.ListTeams` before calling this tool. If the user does not provide a team_id_or_name, the tool will try to find a unique team to use.
	MicrosoftTeams.SendMessageToChat	Sends a message to a Microsoft Teams chat. Provide exactly one of chat_id or user_ids/user_names. When available, prefer providing a chat_id or user_ids for optimal performance. If the user provides user name(s), DO NOT CALL THE `Teams.SearchUsers` or `Teams.SearchPeople` tools first. Instead, provide the user name(s) directly to this tool through the `user_names` argument. It is not necessary to provide the currently signed in user's name/id, so do not call `Teams.GetSignedInUser` before calling this tool either.
	MicrosoftTeams.WhoAmI	Get information about the current user and their Microsoft Teams environment.
