Access the Cal.com API via CLI with a 1Password API key: bookings, event types, schedules and availability. TRIGGERS - calcom, cal.com, list bookings, event types, create booking page.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Cal.com Access
Manage Cal.com bookings and event types programmatically via Claude Code.
> **Self-Evolving Skill**: This skill improves through use. If instructions are wrong, parameters drifted, or a workaround was needed — fix this file immediately, don't defer. Only update for real, reproducible issues.
## MANDATORY PREFLIGHT (Execute Before Any Cal.com Operation)
**CRITICAL**: You MUST complete this preflight checklist before running any Cal.com commands. Do NOT skip steps.
### Step 1: Check CLI Binary Exists
```bash
ls -la "$HOME/.claude/plugins/marketplaces/cc-skills/plugins/calcom-commander/scripts/calcom-cli/calcom" 2>/dev/null || echo "BINARY_NOT_FOUND"
```
**If BINARY_NOT_FOUND**: Build it first:
```bash
cd ~/.claude/plugins/marketplaces/cc-skills/plugins/calcom-commander/scripts/calcom-cli && bun install && bun run build
```
### Step 2: Check CALCOM_OP_UUID Environment Variable
```bash
echo "CALCOM_OP_UUID: ${CALCOM_OP_UUID:-NOT_SET}"
```
**If NOT_SET**: You MUST run the Setup Flow below. Do NOT proceed to Cal.com commands.
### Step 3: Verify 1Password Authentication
```bash
op account list 2>&1 | head -3
```
…Read the whole file at its exact version.
How to install
mdr add terrylica/cc-skills/calcom-access@sha256:58ab644c7cc15bf1The line at the top of this page pins the label git:20261008.a4154ac, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
