> Add a customer, supplier or lead to Holded. Input schema, a tools/call example and an example result.

Source: https://cotlet.dev/docs/mcp/holded/create_contact

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)

Add a customer, supplier or lead to Holded.

Holded MCP tools: https://cotlet.dev/docs/mcp/holded.md

MCP tool: `holded_write → create_contact`

Access: write.

Creates one contact. Type is the contact type Holded uses: customer, supplier, lead, debtor or creditor. The contact reaches no one and you can change it with update_contact, so it runs without asking first. Search with list_contacts first: this call does not check for a duplicate.

## Parameters

| Name | Type | Required | Description |
|---|---|---|---|
| `name` | string | yes | Contact name as it should appear on documents. |
| `type` | enum | no | customer, supplier, lead, debtor or creditor. |
| `email` | string | no | Email address used for sending documents. |
| `tax_id` | string | no | Tax ID as it should appear on documents. |

## For AI agents: sign your user up

Is your user asking you to sign them up for Cotlet? You can do it for them, no account or key needed.

1. Read the fields and their allowed values: GET https://cotlet.dev/api/v1/access-requests
2. Ask the user for each value: email, apps, what you will do with them. If they leave the password to you, generate a strong one and show it to them.
3. Show the user what you will send, then POST it as JSON to https://cotlet.dev/api/v1/access-requests.

One call creates the account and sends the access request; we email the user when access is granted.
