Integration

Add to Calendar PRO integration

Add to Calendar PRO hosts "add to calendar" buttons, event landing pages and RSVP forms. Create, read, update and delete events (single, multi-date or recurring) and the groups they belong to, plus the RSVP, call to action and landing page templates and the button styles events use; read RSVP answers, an event's ics file content, custom domains and email templates; read an event's tracked landing page views, calendar saves and RSVP attendance; and manage webhooks. The polling "latest" routes of groups, styles and templates (no documented answer) are not exposed. Authentication is an API key from the organization settings, sent as it is in the Authorization header (keys can be read-only or read and write).

Claude Code

claude mcp add --transport http livecontext https://livecontext.ai/mcp --header "X-API-Key: YOUR_API_KEY"

Codex (~/.codex/config.toml)

[mcp_servers.livecontext]
url = "https://livecontext.ai/mcp"

[mcp_servers.livecontext.http_headers]
"X-API-Key" = "YOUR_API_KEY"

Cursor, Claude Desktop and other JSON configs
