WHAT IT DOES

What outlook_send_message does on Sage MCP

AI agents use outlook_send_message to create or update resources in Sage MCP, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Sage MCP environment.

RISK

Why outlook_send_message is rated Medium

Sending an email is a write operation that creates a new message in the recipient's mailbox. While reversible in some email systems (can be recalled/deleted in limited cases), the primary effect is creation of new data/communication that has been delivered. The ability to send to CC/BCC recipients and use HTML content increases the potential for misuse (phishing, spam, social engineering).

From the tool's definition Tool description states 'Send a new email message' with support for 'HTML and text body content, with CC and BCC recipients.' This creates new email records irreversibly.

outlook_send_message Rate-limited

outlook_send_message stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
