# Your Teams chats. In your agent. Source: https://corespeed.io/integrations/microsoft-teams Connect Microsoft Teams to Claude Code, Codex, Cursor or any MCP agent through CoreSpeed. Your agent reads your own 1:1 and group chats, finds your teams and their channels, and posts a message to a chat or a channel, using your own Microsoft account. It does not read channel history, and approvals can hold any post. ## Set up an agent Give your agent this line: `set up https://corespeed.io/SKILL.md (read it raw, e.g. with curl)` It fetches the skill at https://corespeed.io/SKILL.md, adds the CoreSpeed MCP server, signs you in (or up), and keeps the skill for next time. Connect Microsoft Teams after setup. Access follows the connected account and its permissions. Create an account: https://app.corespeed.io/sign-up ## Know what was asked. Answer in one place Let your agent read the chat, pull out what is asked of you, and prepare the update before anything is posted. You ask your agent: "Read my Teams chat with Stewart from today. List what Stewart needs from me and by when, and draft a short update for the Releases channel. Do not post it." It calls CoreSpeed: - `teams-chat__list_chats`: ok, 361 ms - `teams-chat__list_chat_messages`: ok, 474 ms It reads from: Microsoft Teams. ### Chat brief: Two asks, one update. Stewart needs the release notes by 3:00 and wants to know if the export fix shipped. **What Stewart needs** - The release notes, by 3:00. - A yes or no on the export fix. **Draft for Releases** - Release 4.2 is out. The export fix is included; notes are in the thread. _Illustrative chat and draft · Fictional data · Nothing posted_ All connectors: https://corespeed.io/docs/connectors ## Catch up on the chat. Post the update Requests you can make once Microsoft Teams is connected. The data is fictional. ### Catch up on a chat Chat with Stewart · Teams chat - Asks for: The release notes by 3:00 - Still open: Is the export fix in? - Your own chats ### Find the channel Product team · Your teams and channels - Team: Product - Channel: Releases - Teams you belong to ### Post under your rules A post that waits · Approval request - Tool: Post to a channel - Policy: Ask before posting to a channel - Waits for a person Full example: https://corespeed.io/solutions/agent-approvals (Markdown: https://corespeed.io/solutions/agent-approvals.md) ## Keep your agent.

Two. Teams covers your teams and posting to their channels; Teams Chat covers your 1:1 and group chats. Connect the ones you need. ### Can my agent read channel messages? No. It lists your teams and channels and can post to a channel, but it reads only your own chats, not channel history. ### Does it work with a personal Microsoft account? No. Microsoft supports these Teams features for work or school accounts only. ### Will it post without asking? Only if you let it. Posting is a separate tool call, and approvals can hold it for a person. How approvals work: https://corespeed.io/solutions/agent-approvals ### Do I have to switch agents? No. CoreSpeed adds tools to the agent you already use: Claude Code, Codex, Cursor, or another MCP client. Each one signs in once. ### Can my agent access every account in our organization? No. Access follows your CoreSpeed identity, each connection's visibility, and the app's own permissions. Personal connections stay private. ### Does this work without connecting an account? No. Connect the app's account first; your CoreSpeed workspace shows what each app needs. The examples on this page use fictional data.
