> **Disclosure:** We make redphonr. PagerDuty details come from PagerDuty's own pricing and product pages as of October 2026.

Both tools wake people up. The difference is what happens next. **PagerDuty** is built so an engineer acknowledges and resolves an incident. **redphonr** is built so an AI agent can ask a person a question and continue with the answer. If you are choosing between them for an agent, that difference decides it.

## Where PagerDuty is stronger

PagerDuty has more than a decade of incident management behind it. Its schedules, escalation policies, analytics, status pages, service catalogue and integrations with monitoring tools are deep. If your agent's alert means "production is broken, an engineer must fix it", PagerDuty is the right home, and the Free plan covers small teams with up to five users and 100 SMS or phone notifications a month.

PagerDuty also ships its own AI agents for SRE work and an MCP integration so LLMs can query and manage incidents.

## Where redphonr is stronger

redphonr starts from a different question: the agent needs a person to decide something before it continues.

- **A real answer, not an acknowledgement.** `request_approval` returns `approved` or `denied` with an optional note. `ask_human` returns one of the options. `collect_input` returns form values. `verify_output` returns a decision on a draft. PagerDuty's model has no equivalent.
- **The agent waits safely.** The agent pauses on a tool call and resumes with the decision. If nobody answers, it gets your default, which should be `deny`.
- **People who are not on an engineering rota.** Approvers are often a finance lead, a founder or an account manager, reachable on WhatsApp or SMS without installing an incident app or taking a paid seat.
- **MCP-native setup.** One `claude mcp add` command, and any MCP agent can ask for approval with no glue code.
- **Pricing for small teams.** redphonr is free to start and does not charge per responder.

## Example: approving a refund

With redphonr, the agent asks and gets an answer:

```python
result = await session.call_tool("request_approval", {
    "message": "Refund $1,240 to order 88213? Customer reports a double charge; Stripe shows two captures.",
    "timeout_seconds": 1800,
    "default": "deny",
})
# {"decision": "approved", "note": "refund one capture only", "responded_via": "whatsapp"}
```

With PagerDuty, the agent would open an incident, a person would acknowledge it, and then you would need a separate way to send "approved" or "denied" back to the agent, such as a custom incident action calling your webhook, plus logic to wait for it.

## Which should you use?

- **Choose PagerDuty** if the alert is an operational incident for an engineering team that already uses it.
- **Choose redphonr** if the agent needs permission, a choice or information from a person, especially someone outside the engineering on-call rota.
- **Use both** if you have both kinds of events. They do not overlap much.

## Frequently asked questions

### Can I use PagerDuty for AI agent approvals?

You can open a PagerDuty incident from an agent and wait for it to be acknowledged or resolved, but PagerDuty has no approve or deny decision, no multiple-choice answer and no input form. You would need to build the decision and the return path yourself with webhooks or custom actions.

### How much does PagerDuty cost?

As of October 2026, PagerDuty's Incident Management has a Free plan for up to 5 users with 100 SMS or phone notifications a month, and a Professional plan at $21 per user per month billed annually or $25 monthly. Its Reliability Platform tiers start at $2,800 a year.

### Does PagerDuty have an MCP server?

Yes. PagerDuty offers MCP integration so LLMs and agents can work with PagerDuty data and incidents. That is for agents to manage incidents, which is a different job from an agent asking a person for permission.

### Can I use redphonr and PagerDuty together?

Yes. Many teams keep PagerDuty for production incidents and use redphonr for agent decisions such as approving a refund, a deploy or a bulk email. They solve different problems.
