# Add appointment

> Adds an appointment to the agenda the way you do for a client who books by phone. Input schema, a tools/call example and an example result.

Source: https://cotlet.dev/docs/mcp/planity/create_appointment

Docs sections: [Get started](https://cotlet.dev/docs.md) · [REST API](https://cotlet.dev/docs/api.md) · [MCP](https://cotlet.dev/docs/mcp.md) · [SDKs & CLI](https://cotlet.dev/docs/sdks.md) · [Integrations](https://cotlet.dev/docs/integrations.md)

Adds an appointment to the agenda the way you do for a client who books by phone.

Planity MCP tools: https://cotlet.dev/docs/mcp/planity.md

MCP tool: `planity_write → create_appointment`

Access: write. Confirm: waits for the user's OK before it runs.

Returns the new appointment as the agenda shows it. The end time follows the duration of the service. The help article on adding an appointment does not say whether Planity notifies the client, so the agent reports what Planity shows after saving. By default you confirm each call; you can switch that off for this tool.

| `staff_id` | string | yes | Id from list_staff. |
| `start` | string | yes | Date and start time, ISO 8601, in the salon's local time. |
| `client_id` | string | no | Existing client from list_clients. Leave out to enter a new client with client_name. |
