AI Agents with Human Checkpoints

Agents that triage, draft and follow up within written limits — scope, budget, checkpoints and an audit log — with a person approving what matters.

In one sentence

WebGx Pro delivers AI Agents with Human Checkpoints for international clients — agents that triage, draft and follow up within written limits — scope, budget, checkpoints and an audit log — with a person approving what matters.

  • Typical engagement 3–8 weeks
  • Tools: Claude, OpenAI, LangGraph, n8n, MCP, your APIs
  • Remote delivery for the UK, Ireland, EU, US, Canada and Australia
  • Scope and price agreed in writing before work starts; a person approves anything that matters

What it solves

A workflow follows fixed steps; an agent is given a goal and works out the steps — reading, deciding, calling tools, checking its own result and asking a person when the risk is real. We build agents for specific jobs with strict scopes, budgets and audit logs, so they are useful on Monday and still trusted in a year.

Typical problems

  • Tasks that need judgement at every step, so no rule-based automation fits
  • A chat pilot that answers questions but cannot actually do anything
  • Agents that run up API bills or wander outside their brief
  • No record of what the AI did, or why
  • Vendors promising ‘autonomous’ when the work needs a person at two points

What changes

A task that needed judgement at every step — triage, research, follow-up, reconciliation — is done first-line by an agent within limits you wrote down, and a person approves anything irreversible. You can see every step it took, what it cost, and how it scored against the evaluation set before it touched real work.

Example workflows

Workflows we build regularly in this service. The “what changes” lines describe the process after the build, not measured results; measured results are published only in case studies, with permission.

Inbound lead research and first touch

Before

A rep spends 20 minutes per lead reading the website, LinkedIn and CRM notes before writing a first email.

After

The agent researches the company, drafts a first email in your voice with sources, and queues it for one-click approval; low-fit leads are tagged and parked.

What changes: research time removed; every lead touched the same day.

Supplier invoice reconciliation

Before

Finance matches invoices to purchase orders by hand and emails suppliers about mismatches.

After

The agent matches, explains discrepancies, drafts the supplier query and books the clean ones; anything ambiguous goes to a person with the evidence attached.

What changes: clean invoices booked without touch; exceptions handled in one queue.

Client onboarding coordinator

Before

A project manager chases documents, sets up folders and systems, and answers ‘what happens next’ emails.

After

The agent collects documents, sets up the accounts, answers status questions from the plan and escalates blockers — within a fixed budget per client.

What changes: consistent onboarding without a coordinator’s week.

What gets automated

  • Task-specific agents with tool access (CRM, email, docs, calendars, APIs)
  • Planning, retries and self-checks with hard limits on cost and scope
  • Human checkpoints for anything irreversible or customer-facing
  • Multi-agent hand-offs (researcher → writer → reviewer)
  • MCP / function-calling integrations with your systems
  • Evaluation sets, audit logs and cost dashboards

Systems we work in

Tools describe the systems we connect; they do not imply partnership or certification.

  • Anthropic Claude
  • OpenAI
  • LangGraph
  • n8n
  • Model Context Protocol (MCP)
  • HubSpot
  • Clio
  • Google Workspace
  • Slack

Human checkpoints and security

The rules that keep this service safe to run in a regulated firm. They are written into the scope, enforced in the build and described in more detail on the security and data page.

  • Written scope: what the agent may read, which tools it may call, and what it must never do
  • A budget per task and a hard stop when it is exceeded
  • Approval gates for anything irreversible, financial or client-facing
  • Evaluation set re-run before every prompt or model change; full audit log in your environment

What every build includes

The difference between an automation that works in a demo and one that still works in a year.

  • Automatic retries when a connected app is briefly unavailable, so nothing is silently lost
  • A run log for every execution — what came in, what was decided, what went out
  • Failure alerts to Slack or email after repeated errors, with a pause switch you control
  • Idempotent steps: running twice never creates duplicates
  • Written handover: a one-page map of the workflow, its owners and how to change it
  • Built in your own accounts — you keep every credential, licence and asset

Questions

What is the difference between an agent and an automation?

An automation runs the same steps every time. An agent is given a goal and chooses the steps, using tools and checking its work. We use automations wherever the steps are known and agents only where judgement is needed — and we tell you which is which.

How do you stop an agent doing something harmful or expensive?

Scope (which tools and records it may touch), budget (tokens, runs, spend per task), checkpoints (a person approves anything irreversible or customer-facing) and a full audit log. The agent can be paused from one switch.

Which models and frameworks?

Claude and OpenAI models behind an interface so they can be swapped; LangGraph, n8n or plain code depending on the job; MCP or function calling for your tools. Nothing runs on our infrastructure.

How do we know it works?

Every agent ships with an evaluation set: real examples with the expected outcome. Changes to prompts or tools are checked against it before they go live.

How does pricing work?

Most engagements start with a fixed-price Automation Reliability Review (from $900). You then get priced options in writing with one price and a delivery date each. Ongoing monitoring and improvements are a monthly retainer you can cancel any month. All prices are in USD.

How quickly can something be live?

A first workflow is usually live within two to three weeks of sign-off. Larger builds are staged so something useful ships early and the rest follows.

What happens when a workflow fails?

Every build ships with retries, a run log and alerts. Anything that does not run as scoped in the first 30 days is fixed at no charge; after that Automation Care covers fixes, or we quote a small fix and turn it around quickly.

Who owns the automations afterwards?

You do. Everything is built in your accounts and documented, and your team is walked through it at handover. You can maintain it yourself or keep us on retainer.
