Microsoft Teams for your AI agent

Give Claude Code, Cursor, Codex or your own agent Microsoft Teams through one MCP URL and one key. Your team signs in to Microsoft Teams once and the agent never holds a token. Reads run at once; anything that changes Microsoft Teams waits for your approval.

Quickstart

Connect Microsoft Teams to your agent in two minutes

Create your account and connect Microsoft Teams with its normal sign-in page.
Open Developers and create an agent key (you can limit it to Microsoft Teams).
Add the server to your client:

Claude Code · Terminal

claude mcp add --transport http vellarin https://hub.vellarin.ai/api/hub/mcp --header "Authorization: Bearer <key>"

Cursor · ~/.cursor/mcp.json (or .cursor/mcp.json in a project)

{
  "mcpServers": {
    "vellarin": {
      "url": "https://hub.vellarin.ai/api/hub/mcp",
      "headers": {
        "Authorization": "Bearer ${env:VELLARIN_HUB_KEY}"
      }
    }
  }
}

Codex · ~/.codex/config.toml

[mcp_servers.vellarin]
url = "https://hub.vellarin.ai/api/hub/mcp"
bearer_token_env_var = "VELLARIN_HUB_KEY"

Questions

Microsoft Teams and AI agents

How do I connect Microsoft Teams to Claude Code, Cursor or Codex?

Create a free Vellarin account, connect Microsoft Teams with its normal sign-in, create an agent key on the Developers page and add the Vellarin Hub MCP server to your client with one line. Your agent then sees the Microsoft Teams actions as tools.

Can my agent change things in Microsoft Teams without asking me?

No. Read actions run at once. Any action that sends, creates, changes or deletes something in Microsoft Teams waits for the workspace owner's approval and then runs exactly once.

Does my agent get my Microsoft Teams password or token?

No. The sign-in lives on the server side. Your agent holds only a Vellarin Hub key, which you can scope to Microsoft Teams alone, cap per day and per month, and revoke at any moment.

What does it cost?

Hub Free includes 500 app calls a month and 1 agent key, with no card. Over the cap the answer is "upgrade or wait", never a charge.
