## Install

### How to install Nolizi Calendar in Claude Code

1. Add the server

```bash
claude mcp add --transport http calendar https://calendar.nolizi.com/mcp --header 'Authorization: Bearer <YOUR_TOKEN>'
```

2. Fill in your credentials

   Replace Bearer <YOUR_TOKEN> with your real value. Keep secrets out of any config file you commit.

3. Verify it's connected

```bash
claude mcp list
```

4. Sharing it with your team?

   Add `--scope project` to write it to .mcp.json in the repository root, which you can commit (with the secrets left as environment variables).

5. Use it in a session

   Ask Claude to use the tools this server exposes (e.g. list_event_types, list_available_slots, list_upcoming_bookings). It discovers them automatically.

### How to install Nolizi Calendar in Claude Desktop

1. Open your MCP config

   macOS: ~/Library/Application Support/Claude/claude_desktop_config.json · Windows: %APPDATA%\Claude\claude_desktop_config.json

2. Add this server

```json
{
  "mcpServers": {
    "calendar": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://calendar.nolizi.com/mcp",
        "--header",
        "Authorization:${AUTH_HEADER}"
      ],
      "env": {
        "AUTH_HEADER": "Bearer <YOUR_TOKEN>"
      }
    }
  }
}
```

3. Fill in your credentials

   Replace Bearer <YOUR_TOKEN> with your real value. Keep secrets out of any config file you commit.

4. Why the wrapper?

   This is a remote (HTTP) server and Claude Desktop only launches local processes, so mcp-remote proxies the connection. It will open a browser window if the server needs OAuth.

5. Restart Claude Desktop

   The tools appear under the 🔌 menu once the app reloads.

### How to install Nolizi Calendar in Cursor

1. Create / edit .cursor/mcp.json in your project

```json
{
  "mcpServers": {
    "calendar": {
      "url": "https://calendar.nolizi.com/mcp",
      "headers": {
        "Authorization": "Bearer <YOUR_TOKEN>"
      }
    }
  }
}
```

2. Fill in your credentials

   Replace Bearer <YOUR_TOKEN> with your real value. Keep secrets out of any config file you commit.

3. Enable it

   Cursor Settings → MCP → toggle the server on. Tools become available to the Composer/Agent.

### How to install Nolizi Calendar in Codex CLI

1. Add to ~/.codex/config.toml

```toml
[mcp_servers.calendar]
command = "npx"
args = ["-y", "mcp-remote", "https://calendar.nolizi.com/mcp", "--header", "Authorization:${AUTH_HEADER}"]
env = { AUTH_HEADER = "Bearer <YOUR_TOKEN>" }
```

2. Fill in your credentials

   Replace Bearer <YOUR_TOKEN> with your real value. Keep secrets out of any config file you commit.

3. Why the wrapper?

   Codex runs MCP servers as local processes, so mcp-remote bridges this HTTP endpoint to stdio.

4. Run Codex

   Codex loads MCP servers from config.toml on startup and exposes their tools to the agent.

```

2. Fill in your credentials

3. Start it

   VS Code shows a ▶ Start action above the server entry. Agent mode (Copilot Chat) can then use the tools.

## Tools

- `list_event_types` — List the bookable event types owned by the configured Nolizi Calendar account. Start here: the returned slug is what every other tool needs. Never guess a slug. Events with required custom questions or email verification cannot be booked through this API — send the person to the event’s public booking page instead.
- `list_available_slots` — Return the live available start/end pairs for one event type. These are real times on a real calendar: show them to the person and let them choose. Do not invent, extrapolate or round a time that is not in this response. Convert times for display only — pass the original values back to create_booking unchanged.
- `list_upcoming_bookings` — List up to 100 upcoming confirmed bookings. This is the only way to verify that a booking exists. Use it after every create or cancel, and use it first whenever a write returned an uncertain outcome.
- `create_booking` — Book a real meeting. This sends invitations and writes to connected calendars, and it cannot be undone except by cancelling. Ask the person to confirm the event, the exact time and the attendee details before calling it, and use their real name and email — never a placeholder. The start and end must be copied verbatim from a recent list_available_slots response; this server re-checks them against 
- `cancel_booking` — Cancel a confirmed booking. This notifies the attendee and removes the meeting from connected calendars, and it cannot be undone. Use an exact booking_id taken from list_upcoming_bookings — never a guessed or reconstructed one. Cancelling one occurrence of a grouped or recurring booking can affect several meetings, so confirm with the person which meetings they mean.
