The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
evite_add_guest ~222
Add guests to an event's draft (un-sent) guest list. Nothing is emailed until you evite_send. Asks the user to confirm first: a confirmation prompt where the client supports one; otherwise the first call returns a preview and a confirmToken, and only a repeat call with that token proceeds (see MCP_CONFIRM_MODE). NB: guests only persist on a finalized (sent/sending) event, not a bare new draft.
| Name | Type | Req | Description |
|---|---|---|---|
| confirmToken | string | – | ONLY for the two-step confirmation fallback (a client without MCP elicitation). The confirmToken from this same tool's phase-1 "confirmation-required" response, passed back ONLY after the user has se… |
| event_id | string | yes | Evite event id (event_id from evite_list_events). |
| guests | array | yes | Guests to add to the draft (un-sent) list. |
No output schema declared.
No examples provided.
evite_broadcast ~273
Broadcast a message to whole RSVP segments of an Evite event at once (e.g. everyone who replied yes/maybe). This really emails every guest in those segments. If a call fails or times out it may still have gone out — check evite_list_messages before calling again. Asks the user to confirm first: a confirmation prompt where the client supports one; otherwise the first call returns a preview and a confirmToken, and only a repeat call with that token proceeds (see MCP_CONFIRM_MODE).
| Name | Type | Req | Description |
|---|---|---|---|
| confirmToken | string | – | ONLY for the two-step confirmation fallback (a client without MCP elicitation). The confirmToken from this same tool's phase-1 "confirmation-required" response, passed back ONLY after the user has se… |
| event_id | string | yes | Evite event id (event_id from evite_list_events). |
| groups | array | yes | RSVP segments to send to, e.g. ['yes','no','maybe']. |
| message | string | yes | Message text to broadcast to the selected RSVP segments. |
| participant_count | integer | – | Optional recipient count the web UI sends along (informational). |
No output schema declared.
No examples provided.
evite_cancel_event ~192
Cancel an Evite event (also used to delete a draft). DESTRUCTIVE — may send a cancellation notice to guests; reversible with evite_reinstate_event. Asks the user to confirm first: a confirmation prompt where the client supports one; otherwise the first call returns a preview and a confirmToken, and only a repeat call with that token proceeds (see MCP_CONFIRM_MODE).
| Name | Type | Req | Description |
|---|---|---|---|
| confirmToken | string | – | ONLY for the two-step confirmation fallback (a client without MCP elicitation). The confirmToken from this same tool's phase-1 "confirmation-required" response, passed back ONLY after the user has se… |
| event_id | string | yes | Evite event id (event_id from evite_list_events). |
No output schema declared.
No examples provided.
evite_create_event ~301
Create an Evite event (as a draft). Requires title, start_datetime, and template_name. Asks the user to confirm first: a confirmation prompt where the client supports one; otherwise the first call returns a preview and a confirmToken, and only a repeat call with that token proceeds (see MCP_CONFIRM_MODE). Evite answers a create with a 500 even when the draft IS created; this tool handles that by re-listing your drafts, and returns created:true with the eventId, or created:"unknown" when it cannot confirm — never call it again for the same event; check the drafts instead.
| Name | Type | Req | Description |
|---|---|---|---|
| confirmToken | string | – | ONLY for the two-step confirmation fallback (a client without MCP elicitation). The confirmToken from this same tool's phase-1 "confirmation-required" response, passed back ONLY after the user has se… |
| end_datetime | string | – | End datetime (ISO 8601, event-local). |
| message | string | – | Event message / description. |
| start_datetime | string | yes | Start datetime (ISO 8601, event-local). Required. |
| template_name | string | yes | Invitation template name (required by the create API; e.g. a gallery design id). |
| title | string | yes | Event title. |
No output schema declared.
No examples provided.
evite_duplicate_event ~182
Duplicate an Evite event into a fresh draft (the "Duplicate event" action). Returns the new draft event id. Asks the user to confirm first: a confirmation prompt where the client supports one; otherwise the first call returns a preview and a confirmToken, and only a repeat call with that token proceeds (see MCP_CONFIRM_MODE).
| Name | Type | Req | Description |
|---|---|---|---|
| confirmToken | string | – | ONLY for the two-step confirmation fallback (a client without MCP elicitation). The confirmToken from this same tool's phase-1 "confirmation-required" response, passed back ONLY after the user has se… |

Set free_only:true to list only free templates. Returns each template’s slug (= template_name) and a readable display name.
