Destructive

Creates a draft reply to an email sender, letting you prepare and update a response before sending it.

Instructions

Create a draft to reply to the sender of a message in either JSON or MIME format. When using JSON format:

  • Specify either a comment or the body property of the message parameter. Specifying both will return an HTTP 400 Bad Request error.

  • If replyTo is specified in the original message, per Internet Message Format (RFC 2822), you should send the reply to the recipients in replyTo, and not the recipients in from.

  • You can update the draft later to add reply content to the body or change other message properties. When using MIME format:

  • Provide the applicable Internet message headers and the MIME content, all encoded in base64 format in the request body.

  • Add any attachments and S/MIME properties to the MIME content. Send the draft message in a subsequent operation. Alternatively, reply to a message in a single operation.

šŸ’” TIP: For HTML replies pass Message.body.contentType: 'html' with Message.body.content as HTML. Note: supplying Message.body replaces the whole draft body, so the original quoted history is not included. Specifying both 'comment' and Message.body returns 400. Signatures are added by the Outlook client only, not via Graph.

Input Schema

NameRequiredDescriptionDefault
bodyYes
confirmNoFor destructive operations when the confirm gate is enabled (MS365_MCP_REQUIRE_CONFIRM=true; off by default). Set to true only after the user has explicitly approved this action. When the gate is on, calls without confirm: true return { error: "confirmation_required" } without touching user data.
messageIdYesValue for the 'messageId' path segment. Pass it under the name 'messageId', not as 'id'. Use the 'id' field of the message object as returned by Microsoft Graph.
includeHeadersNoInclude response headers (including ETag) in the response metadata
excludeResponseNoExclude the full response body and only return success or failure indication

TDQS

A4.6/5.0
Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

The annotations declare this destructive and open-world, so the description goes beyond the minimum needed by adding rules that matter: it says that specifying both comment and Message.body returns HTTP 400, that supplying Message.body replaces the whole draft body and drops the quoted history, and that signatures are added by the Outlook client rather than by Graph. These are behavioral constraints an agent could not learn from the schema or annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is front-loaded with the core action and then uses parallel bullets for the two formats and a clearly marked tip. There is some redundancy, though: the comment-plus-body 400 error appears in the opening bullets and again in the tip, and the MIME paragraph mixes bulk fields with a how-to. That is slightly more text than a strict reading needs.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given a nested-object schema with 5 parameters, 80% description coverage, and no output schema, the description still covers what the agent needs: the two request shapes, the encoding requirements, the mutual-exclusion pitfall, reply routing, where the draft goes next ('send the draft message in a subsequent operation'), and the alternative single-call tool. No critical gap is left for a destructive, open-world write operation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 80%, so the baseline is 3, but the description still adds real meaning: the mutual exclusion of comment and body, how to set contentType html (with the warning that body replaces the quoted history), and the replyTo-vs-from RFC 2822 routing rule. The MIME/base64 guidance for the request body is also useful because the schema does not capture it. The description does not explain confirm, includeHeaders, or excludeResponse, so it falls short of 5.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description opens with a specific verb and resource ('Create a draft to reply to the sender of a message') and immediately bounds scope with 'in either JSON or MIME format'. Combined with the 'reply to the sender' phrasing, it clearly differentiates itself from siblings like create-reply-all-draft and create-forward-draft, and the replyTo paragraph in the body reinforces that.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It lays out two modes with concrete conditions for each: JSON when you want to set Comment or Message.body, MIME when you need headers, attachments, or S/MIME. It also points to the alternative single-operation path ('Alternatively, reply to a message in a single operation'), which maps to reply-mail-message. It never names the sibling tools explicitly, so an agent still has to infer the mapping from the natural-language pointer — hence 4, not 5.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
