Why now: support is where AI agents are going live first

In the past few weeks and months, customer support agents have moved from demos to production. Salesforce unveiled Agentforce 360, positioning fully‑featured enterprise agents across channels. Startups are scaling fast—Wonderful raised a $100M Series A to put AI agents on the front lines of support. And real‑world impact is showing up in metrics: Lyft reported an 87% reduction in average resolution time after deploying Anthropic via Bedrock. Gartner projects that by 2029, agentic AI will autonomously resolve 80% of common support issues. Source.

Meanwhile, developer tooling matured: OpenAI launched AgentKit; Google published the Agent Payments Protocol (AP2) for agent‑initiated purchases; and major labs rolled out browser‑capable agents like Google’s Project Mariner, OpenAI’s Operator, and Amazon’s Nova Act.

Who this guide is for

Support leaders at startups and e‑commerce brands, product and ops teams owning helpdesk/CRM, and founders planning to reduce cost‑per‑resolution while improving CSAT.

Quick definitions

• Customer support AI agent: An autonomous assistant that reads context (tickets, orders, policies), takes actions (refunds, cancellations, status updates), and escalates with human‑in‑the‑loop controls.
• AgentOps: The operational discipline to run agents safely (SLOs, evals, incident playbooks, observability).
• MCP: Model Context Protocol—standard for agent‑tool connections; widely adopted across platforms; also a new security surface you must harden.
• AP2: Agent Payments Protocol—traceable, interoperable agent‑initiated purchases and refunds across platforms.

Buyer’s checklist: capabilities you actually need

1. Channels: Email, chat, voice, SMS, WhatsApp/Instagram DMs. Voice should support low‑latency ASR/TTS and barge‑in.
2. End‑to‑end actions: The agent must do more than answer—e.g., create/modify orders, process returns, issue refunds, update shipping, reset passwords.
3. Knowledge grounding: RAG over help center, policy, and product data with up‑to‑date indexing and per‑brand tone.
4. Helpdesk & CRM integrations: Native connectors for Zendesk, Intercom, Salesforce, Shopify/WooCommerce, and order/inventory systems.
5. Human‑in‑the‑loop: Clear policies for approvals, handoff, and escalation paths; agent transcripts attached to tickets.
6. Security & compliance: Permissioned tools via MCP, OAuth‑based auth, AP2 for payments/refunds, audit logs, PII redaction.
7. Observability: Step‑level traces, structured events, failure taxonomies, and red‑team tools; OpenTelemetry support preferred.
8. Evals & SLOs: Test suites for policy adherence, refund correctness, hallucination, and tone; target CSAT/FCR/containment SLOs.
9. Cost control: Token and latency budgets by policy; caching; model routing; and clear per‑resolution costing.

Enterprise suites (e.g., Salesforce Agentforce 360) bundle many of these; specialist startups may deliver faster iteration and better channel depth. Validate both in a pilot.

KPIs that predict ROI

• Containment rate (no human needed): target an initial 30–50% for L1 workflows; raise with better grounding and tools.
• First‑contact resolution (FCR): percent resolved on first interaction.
• CSAT / Quality: post‑interaction score and calibrated QA rubric.
• Average handle time (AHT) and time to first response.
• Cost per resolution vs baseline human cost.
• Refund/adjustment accuracy and policy compliance.

For examples of SLOs and incident response, see our AgentOps in 2025 playbook.

Security guardrails you should not skip

Agents expand your attack surface—especially via MCP tool catalogs and browser‑control agents. Microsoft has brought MCP support into Windows with extra consent and a controlled registry, a sign that this is powerful and sensitive. Source. Academic work has highlighted MCP‑specific attacks (tool poisoning, preference manipulation, name collisions) that can exfiltrate data or escalate privileges. Study 1, Study 2.

• Identity & attribution: Enforce signed agent identities and mandates; log every action with user, scope, and tool. For commerce actions, prefer AP2‑compatible flows. AP2.
• Least privilege: Narrow tool scopes; separate read vs write servers; revoke unused tools automatically.
• Hardening: Sanitize tool metadata; block prompt‑injection in descriptions; require OAuth instead of raw API keys.
• Observability: Emit step‑level traces to your SIEM; alert on anomalous actions and spoofed identities. Our anti‑spoofing playbook has a ready‑to‑use checklist.

Platform landscape (fast take)

• Salesforce Agentforce 360: Deep CRM/helpdesk integration, enterprise policy controls, Slack surface. TechCrunch.
• Specialist support agents: New entrants like Wonderful focus on multilingual, multi‑channel support at scale. TechCrunch.
• Build with kits: Engineering teams can assemble bespoke agents with OpenAI AgentKit plus browser agents like Mariner and Nova Act for complex workflows.

A 21‑day pilot plan (repeatable, measurable)

Days 1–3: Define scope and data

• Pick 3–5 high‑volume L1 intents (order status, refunds under $X, cancellations, address changes).
• Export 500 recent tickets and policies; build a gold‑set for evals; define pass/fail criteria.
• Success metrics: containment ≥35%, CSAT within −2 pts of baseline, refund accuracy ≥99.5%.

Days 4–7: Integrate and harden

• Connect helpdesk (Zendesk/Intercom/Salesforce) and commerce backends; enforce OAuth scopes.
• Stand up MCP servers with least‑privilege tools; sanitize tool metadata; enable step tracing.
• Route refunds through AP2‑like flows where available; require human approval >$X.

Days 8–14: Evals and supervised launch

• Run offline evals on your gold‑set; fix policy misses. Enable supervised mode (human approves actions).
• Measure AHT, FCR, CSAT, containment; tag failure modes: grounding, tool, policy, language.

Days 15–21: Scale and handoff

• Lift guardrails gradually (auto‑approve low‑risk actions). Add weekend/night coverage first.
• Publish an AgentOps runbook with SLOs, rollback steps, and on‑call rotation. Reference: AgentOps in 2025.
• Archive pilot data, compute ROI, and present a go/no‑go deck to leadership.

Governance and scale

As agent count and complexity grow, you’ll need a place to track identities, permissions, and performance across teams and vendors. See our guide to an Agent System of Record to avoid agent sprawl.

Bottom line

Agents in support are no longer experimental. With proven impact stories (e.g., Lyft’s resolution‑time gains) and maturing vendor options, the winners will be the teams that pilot quickly, measure rigorously, and harden security from day one.
