# Set a chat topic

> Label a chat with one of your chat topics, as an agent does in the About chat block. Input schema, a tools/call example and an example result.

Source: https://cotlet.dev/docs/mcp/jivochat/set_chat_topic

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)

Label a chat with one of your chat topics, as an agent does in the About chat block.

JivoChat MCP tools: https://cotlet.dev/docs/mcp/jivochat.md

MCP tool: `jivochat_write → set_chat_topic`

Access: write.

set_chat_topic sets the topic that the Statistics section counts in its chat topics tab. A topic that does not exist fails at once and the error lists the account's topics. The label reaches nobody outside your team and calling it again with another topic changes it, so it does not wait for your OK.

## Parameters

| Name | Type | Required | Description |
|---|---|---|---|
| `chat_id` | string | yes | Chat ID from list_chats. |
| `topic_id` | string | yes | Topic ID from list_chat_topics. |

## 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.
