# Agent index

> The compact map of Reply for AI agents — what the platform is, core capabilities and workflows, key rules, interface entry points, and every machine-readable file.

**This index maps Reply for agents: a capability table answering can-Reply-do-it, core workflows and objects, behavior rules that surprise the unread, interfaces — REST API on docs.reply.io and the MCP server at mcp.reply.io — plus machine entry points: llms.txt, llms-full.txt, index.json, capabilities.json, search-index.json, sitemap.xml, and a markdown twin for every page.**

_Status: Reviewed — human-edited, facts not yet confirmed against the product._

**Reply is a sales engagement platform**: the Reply Data B2B database with live search and
enrichment, deduplicated contact management, multichannel sequences (email, LinkedIn,
calls, SMS, WhatsApp, tasks, Zapier and condition steps), a consolidated inbox with
AI-assigned reply categories, deliverability protection with MailToaster warm-up,
analytics, and an AI SDR (Jason AI) that runs the loop with drafts-for-review or automatic
sends. This page is the compact index; every claim links to its page.

## Behavior that will surprise you if unread

- A reply to a sequence email sets `Replied` and `Finished` and stops the contact's automation, unless Continue processing steps is enabled — [Reply detection](/behavior/reply-detection) · [Sequence stopping](/behavior/sequence-stopping)
- The contact identifier chosen at import (Email, Last Name, or Phone) is the dedup key — matching rows update or skip, never double — [Contact deduplication](/behavior/contact-deduplication)
- The email account's own daily limit always beats a higher sequence setting — [Mailbox selection](/behavior/mailbox-selection) · [Limits](/reference/limits)
- Follow-ups send from the same email account as the first email; schedules run on UTC and do not adjust for Daylight Saving Time — [When Reply sends](/behavior/sending-schedules)
- Out-of-office replies pause the contact rather than finishing them; automatic handling resumes sending after the number of days you set — [Reply detection](/behavior/reply-detection)

## Known limitations

- Pages labeled **Placeholder** are structural scaffolding — do not cite their detailed claims yet.
- Reply is not a CRM and not a transactional email service — [When to use Reply](/start/when-to-use-reply).
- Interface coverage differs per surface — check [agents.reply.io](https://agents.reply.io) before choosing one.
