We just shipped 3 things in 30 days at KalendMe (MCP, group meetings, bookable resources)
Hey IH,
Quick update from the KalendMe trenches. We've been heads down for the last month and just shipped three things I'm genuinely excited about. Wanted to share both the what and the why, since IndieHackers is one of the few places that cares about the second part.
1. MCP server
We published @kalendme/mcp-server on npm. If you're running an MCP compatible AI client (Claude Desktop, Cursor, etc), you can now talk to your calendar in natural language. "Find me 30 minutes with Ana next week." "Book the studio for Friday." "Show my next 5 meetings."
Honestly this was a 2 day hack that turned into the most "wow" reaction we've gotten in a while. If you're building anything in the AI assistant space, MCP is worth your weekend.
2. Group meetings + Round Robin
Single link, multiple hosts. Either everyone joins (kickoffs, demos) or KalendMe auto assigns each booking to one teammate (cyclic rotation or least load). This was the #1 customer ask for like a year. Building Round Robin properly turned out to be hilariously hard once you get into edge cases (cooldowns, lookaheads, fairness vs. utilization, races on concurrent bookings). Happy to nerd out on the design if anyone's curious.
3. Bookable resources
Rooms, chairs, equipment, vehicles, anything with a schedule. Each resource gets its own public page, ICS feed, granular access modes, and its own email so it can be added as a guest to any calendar invite and book itself via iTIP. Coworking spaces and salons in particular were begging for this.
The meta point
All three are also exposed via REST API and via MCP, so engineering teams can build on top of KalendMe instead of just using it. We're betting hard on "scheduling as a primitive that other products consume," not just "yet another booking page."
Free plan covers a lot of it. Premium is $4/seat/month. Resources count as one seat each, alongside team members (we just added that disclosure across the product, because of course we did).
Would love feedback. Especially if any of this maps to a problem you're hitting in your own tool. https://kalendme.com
Cheers,
Rai
