# Add a tag to a call

> Adds one of your call tags to a call. Input schema, a tools/call example and an example result.

Source: https://cotlet.dev/docs/mcp/ringover/add_call_tag

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 one of your call tags to a call.

Ringover MCP tools: https://cotlet.dev/docs/mcp/ringover.md

MCP tool: `ringover_write → add_call_tag`

Access: write.

Adds the tag to the call, as when you pick Add a tag in the call logs. The tag must exist in list_call_tags, and your Ringover user needs the Tag calls permission; without it the call fails and the agent reports that. It returns the tags the call has now. The tag reaches no one and remove_call_tag undoes it in one call, so it does not wait for your OK.

## Parameters

| Name | Type | Required | Description |
|---|---|---|---|
| `call_id` | string | yes | Call ID from list_calls. |
| `tag` | string | yes | Tag name from list_call_tags. |
