What does it add to Hermes?

Give the agent its own inbox: send and receive email

Agentmail is a skill related to communication and scheduling. It connects the agent to a communication channel or calendar. The important distinction is whether it only reads or can also send and modify.

This plain-language explanation is based on the publisher description. The original text remains visible for verification.

Use it when

Use it when your goal in communication and scheduling is clear and you can limit it to the data and actions it actually needs.

Skip it when

Do not add it merely to experiment when Hermes already has a simpler path, or when you cannot review its source and permissions.

Who is it for?

Best for users who want a repeatable way of working inside Hermes.

Safe first test

Use a test account or draft-only workflow and confirm actual sending requires explicit approval.

Data source

This entry was indexed from Hermes Optional Skills. Our explanation interprets the type and domain without inventing a capability not present upstream.

!
Security review

The source is official or editorially reviewed, but you still need to review permissions and version compatibility.

Safe setup path

Inspect, install, then test.

  1. 01
    Open the source

    Match the publisher, license, and description to your need. Check the real update history.

  2. 02
    Review permissions and secrets

    Never paste a secret value into this site. Use environment-variable names and grant the smallest scope.

  3. 03
    Copy setup only after review

    The controls below copy text. They do not execute commands on your device.

  4. 04
    Test with a non-sensitive task

    Inspect the visible tools, then exclude write or delete tools you do not need.

Install command

Review the command, then copy it.

hermes skills install agentmail

Hermes Belarabi does not execute this command. Installation happens on your device and remains subject to Hermes scanning and your review.

Requirements

Explains the idea itself. Read it slowly; the later sections build on it.

  • 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

Explains the idea itself. Read it slowly; the later sections build on it.

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

Ordered, practical steps. Run one and confirm it worked before moving on.

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):

YAML6 lines
mcp_servers:
  agentmail:
    command: "npx"
    args: ["-y", "agentmail-mcp"]
    env:
      AGENTMAIL_API_KEY: "am_your_key_here"

3. Restart Hermes

All 11 AgentMail tools are now available automatically.

Procedure

Explains the idea itself. Read it slowly; the later sections build on it.

Create an inbox and send an email

  1. Create a dedicated inbox:
  2. Use create_inbox with a username (e.g. hermes-agent)
  3. The agent gets address: hermes-agent@agentmail.to
  4. Send an email:
  5. Use send_message with inbox_id, to, subject, text
  6. Check for replies:
  7. Use list_threads to see incoming conversations
  8. Use get_thread to read a specific thread

Check incoming email

  1. Use list_inboxes to find your inbox ID
  2. Use list_threads with the inbox ID to see conversations
  3. Use get_thread to read a thread and its messages

Reply to an email

  1. Get the thread with get_thread
  2. Use reply_to_message with the message ID and your reply text

Example Workflows

Explains the idea itself. Read it slowly; the later sections build on it.

Sign up for a service:

Text4 lines
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:

Text3 lines
1. create_inbox (username: "hermes-outreach")
2. send_message (to: user@example.com, subject: "Hello", text: "...")
3. list_threads to check for replies

Pitfalls

Explains the idea itself. Read it slowly; the later sections build on it.

  • Free tier limited to 3 inboxes and 3,000 emails/month
  • Emails come from @agentmail.to domain on free tier (custom domains on paid plans)
  • Node.js (18+) is required for the MCP server (npx -y agentmail-mcp)
  • The mcp Python package must be installed: pip install mcp
  • Real-time inbound email (webhooks) requires a public server — use list_threads polling via cronjob instead for personal use

Verification

Explains the idea itself. Read it slowly; the later sections build on it.

After setup, test with:

Text1 line
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.
