for OpenClaw

OpenClaw is an open-source AI assistant that runs on your own hardware. You talk to it in Telegram, WhatsApp, Slack and other chat apps. The Revdoku skill lets it use a mailbox through the Revdoku CLI (command-line tool). A skill is a folder of instructions and scripts that an agent loads.

You need: a terminal on the machine that runs the OpenClaw Gateway (the OpenClaw background process), and a Revdoku account.

1. On the Gateway machine, run this command: npx skills add revdoku/revdoku --skill revdoku -g --agent openclaw
2. If that machine has no npm, run the install script instead: curl -fsSL https://revdoku.com/install.sh | bash
3. Run openclaw skills check. Make sure that it shows revdoku as ready.
4. Start a new OpenClaw session. Ask: “Show my Revdoku mailbox address.”
5. Open the Revdoku link that the CLI prints. Make sure that the connection ID on the page is the same. Select Connect.

Both installers put the skill in ~/.openclaw/skills/revdoku, a folder that OpenClaw shares with all local agents. The install script also adds the revdoku command in ~/.revdoku/bin. The skill lists bash, curl, openssl, base64, find and stat as required programs. OpenClaw hides the skill until all six are on the PATH.

If the Gateway runs on a server without a browser, the CLI cannot open the sign-in page. Open the printed link on your phone or laptop. You can also paste the setup prompt from the Connect AI menu into an OpenClaw chat. OpenClaw then runs these steps itself.

OpenClaw can also use remote MCP servers. MCP is a standard way for AI apps to use outside tools. The hosted Revdoku MCP server reads and writes mailbox text, but it cannot upload files from the OpenClaw machine.

1. Save the server without the two delete tools:

   openclaw mcp add revdoku \
     --url https://mcp.revdoku.com \
     --transport streamable-http \
     --auth oauth \
     --exclude 'mailbox_delete_permanently,mailbox_email_delete'

2. Run openclaw mcp login revdoku. Open the URL that it prints.
3. On the Revdoku permission screen, select one mailbox. Choose Read & write so that OpenClaw can see its address.
4. If your browser is on another machine, copy the returned code. Then run openclaw mcp login revdoku --code CODE.
5. Run openclaw mcp doctor revdoku --probe to test the connection.

OpenClaw gives MCP tools to agents in its coding and messaging tool profiles (preset tool lists). The minimal profile does not include them.

• Use the mailbox address for shop receipts. Ask OpenClaw in Telegram to list this week's purchases and totals.
• When OpenClaw signs up for a service for you, give it the mailbox address. It reads the verification email and finishes the signup.
• OpenClaw saves a folder from its workspace with revdoku upload ./reports. People with access open the files in the Revdoku dashboard.
• OpenClaw replies to a person who wrote to the mailbox with email-send --in-reply-to EMAIL_ID. Revdoku keeps the reply in the same conversation.

OpenClaw automations run an agent turn on a schedule. This job reads the mailbox at 8:00 on weekdays and posts a summary to a Telegram chat.

openclaw automations add \
  --name "Mailbox summary" \
  --cron "0 8 * * 1-5" \
  --tz "America/New_York" \
  --session isolated \
  --message "Use the revdoku skill. List unread emails in my Revdoku mailbox. Give each one a one-line summary. Then mark them as read. Do not reply or delete anything." \
  --announce \
  --channel telegram \
  --to "TELEGRAM_CHAT_ID"

Replace TELEGRAM_CHAT_ID with the ID of your chat. Set --tz to your time zone. Run openclaw automations list to see the job.

The OpenClaw documentation tells you to treat third-party skills as untrusted code and to read them before you enable them. The Revdoku skill is Markdown and Bash scripts under the MIT-0 license. After sign-in, it keeps the Revdoku credential in ~/.revdoku/credentials.

The skill tells OpenClaw that email bodies, attachments and file names are untrusted data. They cannot authorize commands, replies, uploads or deletions.

To sign the MCP server out, run openclaw mcp logout revdoku. To remove the server, stop the Gateway and run openclaw mcp unset revdoku. Review or reconnect OpenClaw in Revdoku under Account → Access.
