Unreviewed submission. This plugin was generated from a third-party submission form and has not been reviewed by Cursor. Do not merge until it has been reviewed and tested.

Summary

Adds third_party/ppj-venture-labs/, a remote MCP plugin for Kalender Sync (Google Calendar, Outlook, iCloud, and CalDAV availability, events, invitations, and calendar syncs).

• mcp.json stores the hosted server URL exactly as submitted; .cursor-plugin/plugin.json references it with "mcpServers": "./mcp.json" (same pattern as Add PitchBook third-party MCP plugin #796 / PitchBook).
• plugin.json with category integrations and logo: assets/logo.png.
• README with install steps and the MCP JSON block, plus CHANGELOG and LICENSE.
• One row in the root README plugins table and one entry appended to .cursor-plugin/marketplace.json. .claude-plugin/marketplace.json is unchanged.

Submission

• Contact: Paul Koch, PPJ Venture Labs UG (haftungsbeschränkt), paul@ppj.ventures
• Publisher handle: ppj-venture-labs
• plugin_url: https://app.kalender-sync.de/mcp (remote MCP server, Streamable HTTP, OAuth)
• Website: https://kalender-sync.de/en/mcp/
• Listing targets: Grok, Grok Bot, Cursor

Testing instructions (as submitted)

Connect https://app.kalender-sync.de/mcp via OAuth. Use two test calendars with full details and write/manage/sync rights. List calendars; check availability; create, find, update and delete a test event. Preview/confirm a one-way busy-only sync; list, diagnose, pause/resume, preview/confirm deletion; verify cleanup. Grok Web passed this flow on 25 Oct 2026. Grok Bot/Cursor E2E, refresh, revocation, denied-access, RSVP and recurrence were not tested. Private reviewer access on request. Terms 3.1 question: are existing free/paid service tiers allowed with no extra plugin fee?

Note for reviewers: the submitter says Cursor end-to-end was not tested, and asks a terms question (section 3.1, existing free/paid tiers) that needs an answer from the partnerships side.

Logo

The submitted logo_url (https://kalender-sync.de/favicon.png) could not be downloaded: kalender-sync.de and app.kalender-sync.de are unreachable from the build environment. The committed assets/logo.png (216×216 PNG, calendar icon) is the avatar of the kalender-sync GitHub organization, whose profile lists https://kalender-sync.de/en/ as its website. Please confirm it matches the submitted favicon.

Validation

node scripts/validate-plugins.mjs → All plugins validated successfully. The MCP server itself was not exercised from this environment.

Note

Medium Risk
Unreviewed third-party listing that routes agents to a hosted OAuth MCP with calendar read/write and sync controls; Cursor E2E was not verified in the submission.

Overview
Adds the Kalender Sync (ppj-venture-labs) integration to the Cursor plugin marketplace: a new third_party/ppj-venture-labs/ package with manifest, docs, and an HTTP MCP config pointing at https://app.kalender-sync.de/mcp (OAuth; no local server).

Marketplace wiring: appends a ppj-venture-labs entry to .cursor-plugin/marketplace.json and a matching row in the root README.md plugins table. The listing describes availability checks, event CRUD/invitations, and calendar sync management across Google Calendar, Outlook, iCloud, and CalDAV.

Follows the same remote-MCP pattern as other third_party plugins (mcp.json + "mcpServers": "./mcp.json" in plugin.json).
