Elicit result

Version Support

• MCP 2025-11-25: action, content (form mode), _meta
• MCP 2025-11-25 draft (SEP-1330): Clarified content field behavior

Content Field Behavior (SEP-1330 Clarification)

The content field is only present when:

1. action is "accept" (user submitted the form), AND
2. Mode was "form" (in-band structured data collection)

The content field is omitted when:

• Action is "decline" or "cancel"
• Mode was "url" (out-of-band, data doesn’t transit through MCP)

Example

Form mode with accept:

{
  "action": "accept",
  "content": {
    "name": "Alice",
    "email": "alice@example.com"
  }
}

URL mode with accept:

{
  "action": "accept"
}

Note: No content field - data was collected out-of-band

Fields

action: ElicitationAction

The user action in response to the elicitation

• accept: User submitted the form/confirmed the action
• decline: User explicitly declined the action
• cancel: User dismissed without making an explicit choice

content: Option<HashMap<String, Value>>

The submitted form data, only present when action is “accept” and mode was “form”.

Contains values matching the requested schema. Omitted for:

• action is "decline" or "cancel"
• URL mode responses (out-of-band data collection)

Per MCP 2025-11-25 draft (SEP-1330), this clarification ensures clients understand when to expect form data vs. out-of-band completion.

_meta: Option<Value>

Optional metadata per MCP 2025-11-25 specification
