Microsoft Teams for AI agents

Microsoft Teams combines chat, video meetings, and file sharing inside Microsoft 365 for distributed team collaboration and company-wide communication across departments. Connect it once through Arc0, and your agent, or Claude, ChatGPT and Cursor, can use it through one MCP endpoint, limited to what each user approved.

Microsoft Teams in three steps.

  1. 01Your users connect Microsoft TeamsThey sign in to Microsoft Teams on Arc0 Connect, under your brand, and approve the access you ask for.
  2. 02You set the rulesReads run, writes like “create Team” can wait for the user, and “delete channel tab” can be denied outright.
  3. 03Any agent can actYour agent calls Microsoft Teams through the Arc0 SDK or MCP, and so can Claude, ChatGPT and Cursor. Every call lands on the audit log.
POLICY.TS
await arc0.policies.set('microsoft_teams', {
  read: 'allow',
  write: 'ask',        // create_team

04 · AUTH AND DATA

How Microsoft Teams connects.

Users sign in to Microsoft Teams on Arc0 Connect and approve the scopes you request. Build with Arc0’s Microsoft Teams OAuth app, or bring your own so the Microsoft Teams consent screen names you. Tokens refresh automatically, and you can export them whenever you want.

The same Microsoft Teams connection serves your agent over MCP and your own backend over REST and the proxy, so a user connects once. How Arc0 handles credentials →

07 · FAQ

Microsoft Teams and Arc0, answered.

Q01

Can I use Microsoft Teams with Claude, ChatGPT or Cursor?

Yes. Connect Microsoft Teams to Arc0 once, then add your Arc0 MCP URL to Claude, ChatGPT, Cursor, Claude Code or any other remote-MCP client. Each assistant only gets the Microsoft Teams actions you allow.

Q02

How do users connect Microsoft Teams?

Users sign in to Microsoft Teams on Arc0 Connect and approve the scopes you request. Build with Arc0’s Microsoft Teams OAuth app, or bring your own so the Microsoft Teams consent screen names you. Tokens refresh automatically, and you can export them whenever you want.

Q03

Which Microsoft Teams actions can my agent take?

174 in total: 72 read, 76 write and 26 destructive, such as “create Team”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in Microsoft Teams?

Yes. Actions like “delete channel tab” are graded destructive. Set destructive actions to deny, or to ask so the user approves each one, and blocked calls still show up on the audit log.

Q05

Can my own backend call Microsoft Teams too?

Yes. The same Microsoft Teams connection is available over REST and through the Arc0 proxy, so your product and your agent share one connection per user.
