# Add prospects to a sequence

Enrolls one or more prospects in an Outreach sequence, sending from the mailbox you choose, and returns the status of the batch.

Note: Enrolling starts the sequence's automation, so confirm the sequence, mailbox and prospects first. Find the sequence with `sequence_search` or `GET /sequences`, and check the result with `sequence_state_search`.

## 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": { "outreach": { "url": "https://api.outreach.io/mcp" } } }
```

Call the MCP tool `sequence_add_prospects`.

Server URL: https://api.outreach.io/mcp

### API (official)

- Base URL: https://api.outreach.io/api/v2
- Endpoint: `POST /batches/actions/prospectsAddToSequence`
- Auth: an OAuth access token, sent as `Authorization: Bearer <token>`
- Docs: https://developers.outreach.io/api/getting-started

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.
