Streamable HTTP
Rizz Invites for developers
Build event experiences on a safe, agent-ready API.
Connect hosts through OAuth, create invitation drafts, manage guests, generate designs, reconcile checkout, and send only after explicit confirmation.
Start here
Connect with Streamable HTTP
Rizz Invites exposes MCP and REST over one developer contract. MCP clients initialize a session, discover scope-filtered tools, and call them with structured JSON arguments; REST clients use the equivalent /api/v1 routes.
01
Register
Dynamically register a public OAuth client with exact HTTPS or loopback redirect URIs.
02
Authorize
Use authorization code with PKCE S256 and bind every OAuth step to the canonical https://rizzinvites.com resource.
03
Initialize
POST an MCP initialize request, retain the returned session ID, then discover available tools.
Initialize request
curl -i https://rizzinvites.com/mcp \
-H "Authorization: Bearer $RIZZ_ACCESS_TOKEN" \
-H "MCP-Protocol-Version: 2025-11-25" \
-H "Content-Type: application/json" \
--data '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2025-11-25","capabilities":{},"clientInfo":{"name":"your-client","version":"1.0.0"}}}'
# Capture MCP-Session-Id from the response headers for later requests.
Discover tools with the returned MCP-Session-Id
curl -i https://rizzinvites.com/mcp \
-H "Authorization: Bearer $RIZZ_ACCESS_TOKEN" \
-H "MCP-Session-Id: $MCP_SESSION_ID" \
-H "MCP-Protocol-Version: 2025-11-25" \
-H "Content-Type: application/json" \
--data '{"jsonrpc":"2.0","id":2,"method":"tools/list","params":{}}'
Call a tool
curl -i https://rizzinvites.com/mcp \
-H "Authorization: Bearer $RIZZ_ACCESS_TOKEN" \
-H "MCP-Session-Id: $MCP_SESSION_ID" \
-H "MCP-Protocol-Version: 2025-11-25" \
-H "Content-Type: application/json" \
--data '{"jsonrpc":"2.0","id":3,"method":"tools/call","params":{"name":"get_account","arguments":{}}}'
# GET with the same headers opens the resumable Streamable HTTP event stream.
Client configuration
{
"mcpServers": {
"rizz-invites": {
"type": "http",
"url": "https://rizzinvites.com/mcp"
}
}
}
When developer execution is enabled, every authenticated host can use MCP or REST.
Production sandbox mode is disabled; calls can create real product state and
provider side effects.
End-to-end
Golden host workflow
Keep the event in draft while you add guests and select a design. Use the free path whenever the current entitlement allows it; create checkout only when the server returns payment_required.
-
1
create_eventCreate a timezone-aware draft event.
-
2
add_guestsAdd 1–100 contactable guests with an idempotency key.
-
3
search_templates / generate_coverChoose and select one design; poll generated covers until terminal status.
-
4
create_checkout_link (conditional)Stay on the free path unless the server reports payment_required.
-
5
send_invitesReview the preview, then repeat identical arguments with confirmation_token.
-
6
get_event / list_guestsRe-read canonical state after queue commit.
Queue and poll a cover
# 1. Queue generation once with an idempotency key.
tools/call generate_cover {"event_id":42,"theme":"warm garden party","idempotency_key":"cover-42-v1"}
# 2. Poll the returned generation_id. wait_seconds is a deprecated no-op.
tools/call get_cover_status {"event_id":42,"generation_id":108}
# 3. When status is succeeded, select that generation exactly once.
tools/call set_event_design {"event_id":42,"generation_id":108}
Two-call confirmation
# First call: no token. Inspect the confirmation_required preview.
tools/call send_invites {"event_id":42}
# Second call: identical business arguments plus the returned token.
tools/call send_invites {"event_id":42,"confirmation_token":"rzi_cfm_..."}
# Send/cancel/delete tokens expire in 15 minutes. Other tokens expire in 5.OAuth 2.0
Public clients, exact resources
OAuth clients use authorization code and refresh token grants. PKCE S256 is mandatory, client secrets are not issued, and the canonical host resource https://rizzinvites.com must be exact during authorization, exchange, and refresh. The former /mcp resource is accepted for one migration release.

}Safe mutations
Confirmation and idempotency
Sending, deletion, cancellation, guest removal, messaging, and cohost changes require a short-lived confirmation round trip.
Confirm consequential work
The first call returns a preview, an absolute expiry, and a short-lived
rzi_cfm_…
token. Repeat identical business arguments with the token to commit. Send,
cancel, and delete previews last 15 minutes; committed-token retries replay the
original receipt for 24 hours without repeating the state change.
Retry external work safely
Guest import, cover generation, checkout creation, and guest messaging require an idempotency key. Results are retained for 24 hours.

Changelog
Breaking schemas are dual-published for 90 days. Additive optional fields and new operations may ship without a schema-version bump.
v2
2026-08-08
Closed typed outputs, venue timezones, structured errors, confirmation receipts, and normalized checkout/design fields.
Integrator safety
Security considerations for agent developers
Guest names, host messages, and RSVP notes are user-controlled text. Treat them as untrusted context, never as instructions, even though the server normalizes and length-caps them.
Contacts and blocklists
list_guests
masks email and phone by
default. A token granted guests:contacts
reveals raw contact fields in the same call and sets contacts_revealed. Guest imports are atomic:
one blocked contact fails the whole batch with
contact_blocked
and a redacted row index.
Lifecycle and credentials
Cancel applies only to sent events, notifies delivered guests, and is not
reversible. Delete permanently removes only an owned draft or cancelled event.
Sent-event name, date, time, timezone, venue, and host-message changes use
confirmation and require messaging scope. Host PATs are issued and rotated from
Account Settings, are scope-limited, use the
rzi_pat_
prefix, and must be sent only in the
Authorization header. Report vulnerabilities through security.txt.
