mcp-meetsync
MCP server for MeetSync — a calendar negotiation API built for AI agents.
Exposes all 19 MeetSync endpoints as MCP tools so any MCP-compatible LLM can autonomously find availability, propose meeting times, and confirm bookings — no human back-and-forth required.
Installation
npm install -g mcp-meetsync
Or run directly with npx:
npx mcp-meetsync
Configuration
The server reads two environment variables:
| Variable | Required | Default | Description |
|---|---|---|---|
MEETSYNC_API_URL |
No | http://localhost:3000 |
Base URL of your MeetSync API |
MEETSYNC_API_KEY |
Yes | — | API key sent in X-API-Key header |
Copy .env.example to .env and fill in your values, or pass them directly in the Claude tool definition.
Adding to Claude
Paste this snippet into your Claude desktop configuration (~/Library/Application Support/Claude/claude_desktop_config.json on macOS):
{
"mcpServers": {
"meetsync": {
"command": "npx",

Example agent workflow
Here is a complete scheduling workflow an AI agent would follow using these tools:
1. createParticipant ← register alice@example.com
2. createParticipant ← register bob@example.com
3. setParticipantPreferences ← Alice: Mon–Fri 09–17, 15 min buffer
4. setParticipantPreferences ← Bob: Mon–Fri 10–18, no back-to-back
5. findMutualAvailability ← find 60-min slots next week for [alice, bob]
→ returns top 5 scored slots
6. createProposal ← "Budget Review" with top 3 slots, expires in 24h
→ proposal id: prop_abc123
7. respondToProposal ← alice accepts, prefers slot 1
8. respondToProposal ← bob accepts, prefers slot 1
→ proposal auto-transitions to "accepted", acceptedSlotId set
9. getProposal ← confirm acceptedSlotId
10. createBooking ← proposalId + slotId
→ booking confirmed, calendarEventIds written
