Inform Human

One tool that gives an AI agent a way to reach a person: send a human an email, right from the middle of whatever the agent is doing.

Why

Agents run on their own most of the time, but the right move is sometimes to tell a human: a decision that needs a person, a finished result worth flagging, or a question the agent can't answer itself. Inform Human is the smallest possible way to do that — no email provider to wire up, no SMTP, one tool call.

How to use it

1. Add the connector

The server speaks Streamable HTTP at:

https://mcp.informhuman.com/mcp

Add it to any MCP-capable client (Claude, Cursor, an Agents SDK app, your own code). Authentication is OAuth 2.1 via Descope — sign in with a passkey or one-time passcode: the client discovers the sign-in flow automatically (Protected Resource Metadata) — no tokens to copy or rotate.

2. Authorize who it may email

So the service can't be used to spam, it only emails recipients you've explicitly authorized. Sign in to the portal and add an inbox (the recipient confirms by clicking an email link) or a whole domain (prove ownership with a DNS TXT record).

3. Call the tool

One tool is exposed:

inform_human(
  subject:   "Deploy needs your sign-off",
  message:   "Staging is green. Reply in Slack to promote to prod.",
  recipient: "[email protected]",   // required; must be an authorized recipient
  urgency:   "high"               // optional; "high" prefixes [URGENT]
)

The email is sent from [email protected]. If the recipient isn't authorized, the call is refused with a link to authorize it. Delivery is one-way: the human reads it out of band and follows up however they like.

4. That's it

The agent gets back a confirmation with a delivery id. No inbox to poll, no webhook to host.

The short version

Inform Human — a hosted MCP tool that lets an AI agent email a human in one tool call. Sign in with OAuth, authorize who it may reach, and the agent can notify a person mid-task. Email arrives from the verified informhuman.com domain.
