Outlook for your AI agent

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

Quickstart

Connect Outlook to your agent in two minutes

Create your account and connect Outlook with its normal sign-in page.
Open Developers and create an agent key (you can limit it to Outlook).
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

Outlook and AI agents

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

Create a free Vellarin account, connect Outlook 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 Outlook actions as tools.

Can my agent change things in Outlook without asking me?

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

Does my agent get my Outlook 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 Outlook 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.
