# agentmail output preview
## PART A: Task fit
- Use case: Give the agent its own dedicated email inbox via AgentMail. Send, receive, and manage email autonomously using agent-owned email addresses (e.g. hermes-agent@agentmail.to)..
- Inputs: target material, constraints, expected output, and acceptance criteria.
- Evidence boundary: follow “Requirements / When to Use / Setup” and do not present inference as author intent.
## PART B: Execution result
- **01** The card summarizes the use case; runtime output centers on “Give the agent its own dedicated email inbox via AgentMail. Send, receive, and manage email autonomously using agent-owned email addresses (e.g. hermes-agent@agentmail.to).”.
- **02** When the source has headings, the agent prioritizes “Requirements / When to Use / Setup” so the result follows the author’s structure.
- **03** Typical output includes task judgment, concrete steps, required commands or file edits, validation, and follow-up options.
- **04** Risk context follows the fingerprint: read files, write/modify files, read environment variables; may access external network resources; requires Vendor-specific API keys.
## Running Rules
- read files, write/modify files, read environment variables; may access external network resources; requires Vendor-specific API keys.
- Validate with a small sample before expanding scope.
- Return the result, validation criteria, and next iteration options. The source does not require a stable slash command. After installation, invoke the skill by name and describe the task.
Name target files or source material, expected output, forbidden changes, and whether network or shell access is allowed. Permission fingerprint: read files, write/modify files, read environment variables.
Start with a small task and check whether the result follows “Requirements / When to Use / Setup”. Inspect diffs, logs, previews, or tests before expanding scope.
Confirm the final output includes a concrete result, evidence, and next action. If it stays generic, tighten inputs, boundaries, and acceptance criteria.

# agentmail
## When to use

- Use it when the task has clear inputs, repeatable steps, and validation criteria.
## What to provide
- Target material, scope, expected result, and forbidden changes.
- Whether network, commands, file writes, or external services are allowed.
## Execution rules
- Organize steps around “Requirements / When to Use / Setup” and keep inference separate from source facts.
- read files, write/modify files, read environment variables; may access external network resources; requires Vendor-specific API keys.
- Validate with a small sample before expanding the task.
## Output requirements
- Return the deliverable, key evidence, validation method, and next action.
- Mark missing information as unknown; do not invent commands, platforms, or dependencies. The author source anchors workflow facts; repository files anchor sources and commands; Fluxly only adds fit, limitations, and quality judgment.
skill "agentmail" {
input -> user goal + target files + boundaries + acceptance criteria
context -> Requirements / When to Use / Setup
rules -> SKILL.md triggers / order / output contract
runtime -> Node.js / Python | read files, write/modify files, read environment variables | may access external network resources
guardrails -> requires Vendor-specific API keys + small-sample validation + diff/log review
output -> copyable result + checklist + next iteration
} AgentMail — Agent-Owned Email Inboxes
Requirements
- AgentMail API key (required) — sign up at https://console.agentmail.to (free tier: 3 inboxes, 3,000 emails/month; paid plans from $20/mo)
- Node.js 18+ (for the MCP server)
When to Use
Use this skill when you need to:
- Give the agent its own dedicated email address
- Send emails autonomously on behalf of the agent
- Receive and read incoming emails
- Manage email threads and conversations
- Sign up for services or authenticate via email
- Communicate with other agents or humans via email
This is NOT for reading the user's personal email (use himalaya or Gmail for that). AgentMail gives the agent its own identity and inbox.
Setup
1. Get an API Key
- Go to https://console.agentmail.to
- Create an account and generate an API key (starts with
am_)
2. Configure MCP Server
Add to ~/.hermes/config.yaml (paste your actual key — MCP env vars are not expanded from .env):
mcp_servers:
agentmail:
command: "npx"
args: ["-y", "agentmail-mcp"]
env:
AGENTMAIL_API_KEY: "am_your_key_here"
3. Restart Hermes
hermes
All 11 AgentMail tools are now available automatically.
Available Tools (via MCP)
| Tool | Description |
|---|---|
list_inboxes |
List all agent inboxes |
get_inbox |
Get details of a specific inbox |
create_inbox |
Create a new inbox (gets a real email address) |
delete_inbox |
Delete an inbox |
list_threads |
List email threads in an inbox |
get_thread |
Get a specific email thread |
send_message |
Send a new email |
reply_to_message |
Reply to an existing email |
forward_message |
Forward an email |
update_message |
Update message labels/status |
get_attachment |

Procedure
Create an inbox and send an email
- Create a dedicated inbox:
- Use
create_inboxwith a username (e.g.hermes-agent) - The agent gets address:
hermes-agent@agentmail.to
- Use
- Send an email:
- Use
send_messagewithinbox_id,to,subject,text
- Use
- Check for replies:
- Use
list_threadsto see incoming conversations - Use
get_threadto read a specific thread
- Use
Check incoming email
- Use
list_inboxesto find your inbox ID - Use
list_threadswith the inbox ID to see conversations - Use
get_threadto read a thread and its messages
Reply to an email
- Get the thread with
get_thread - Use
reply_to_messagewith the message ID and your reply text
Example Workflows
Sign up for a service:
1. create_inbox (username: "signup-bot")
2. Use the inbox address to register on the service
3. list_threads to check for verification email
4. get_thread to read the verification code
Agent-to-human outreach:
1. create_inbox (username: "hermes-outreach")
2. send_message (to: user@example.com, subject: "Hello", text: "...")
3. list_threads to check for replies
Pitfalls
- Free tier limited to 3 inboxes and 3,000 emails/month
- Emails come from
@agentmail.todomain on free tier (custom domains on paid plans) - Node.js (18+) is required for the MCP server (
npx -y agentmail-mcp) - The
mcpPython package must be installed:pip install mcp - Real-time inbound email (webhooks) requires a public server — use
list_threadspolling via cronjob instead for personal use
Verification
After setup, test with:
hermes --toolsets mcp -q "Create an AgentMail inbox called test-agent and tell me its email address"
You should see the new inbox address returned.
