Email infrastructure for AI agents. Create accounts, send/receive emails, manage webhooks, and check karma balance via the AgentMail API.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# AgentMail — Email for AI Agents
AgentMail gives AI agents real email addresses (`@theagentmail.net`) with a REST API. Agents can send and receive email, sign up for services (GitHub, AWS, Slack, etc.), and get verification codes. A karma system prevents spam and keeps the shared domain's reputation high.
Base URL: `https://api.theagentmail.net`
## When to Use
- An AI agent needs a real inbox/outbox for signups, verification flows, or transactional communication.
- You need to provision AgentMail accounts, send messages, read inbox contents, or register inbound webhooks.
- You need to monitor karma usage or wire email events into agent automation.
## Quick start
All requests require `Authorization: Bearer am_...` header (API key from dashboard).
### Create an email account (-10 karma)
```bash
curl -X POST https://api.theagentmail.net/v1/accounts \
-H "Authorization: Bearer am_..." \
-H "Content-Type: application/json" \
-d '{"address": "my-agent@theagentmail.net"}'
```
Response: `{"data": {"id": "...", "address": "my-agent@theagentmail.net", "displayName": null, "createdAt": 123}}`
### Send email (-1 karma)
```bash
…Read the whole file at its exact version.
How to install
mdr add ghosteken/agent-harness/agentmail@sha256:a68e8fc0b2b0e1e8The line at the top of this page pins the label git:20260721.efafd9c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
