# Tag a conversation

Adds one or more existing tags to a conversation.

Note: Takes tag IDs (`tag_...`), not names: find them with `list_tags` on the MCP server or `GET /tags` on the API.

## Set up

Use the first option your agent supports.

### MCP (official, remote)

Add this server to your agent's MCP settings, then sign in when asked.

```json
{ "mcpServers": { "front": { "url": "https://mcp.frontapp.com/mcp" } } }
```

Call the MCP tool `tag_conversation`.

Server URL: https://mcp.frontapp.com/mcp

Note: Connect with the client ID and secret of a Front developer app that has MCP Server access: Front has no dynamic client registration.

### API (official)

- Base URL: https://api2.frontapp.com
- Endpoint: `POST /conversations/{conversation_id}/tags`
- Auth: send the header `Authorization: Bearer $FRONT_API_KEY`
- Get a key: https://dev.frontapp.com/docs/create-and-revoke-api-tokens
- Docs: https://dev.frontapp.com/reference/introduction

Before anything else, confirm access with the cheapest read-only call, like a list or a search. Never send or change anything to test access.

## Rules

- Ask the user before anything that sends messages, costs money, or changes data, and say how many records it touches. One approval covers a batch the user has seen.
- Never print API keys.
