--- name: commsharbor description: Use domain mail without operating a mail server, or inspect public email-security records. Evaluate free DNS checks and mailbox activation before buying service. license: MIT-0 --- # CommsHarbor MCP tools: `commsharbor_email_security_check`, `commsharbor_email_workspace`, `pricing`, `commsharbor_email_domain_get`, `commsharbor_email_domain_setup`, `commsharbor_email_mailbox_create`, `commsharbor_email_job_get`, `commsharbor_email_google_catalog`, `commsharbor_email_google_connect`. Use the managed mail server, webmail and organization workspace instead of operating that stack yourself. ## Everyday requests Use this skill for domain-mail setup, mailbox management and public email-protection questions. Reuse the authorized domain and organization. Ask for missing identity or scope. Start by reading current state. A diagnostic request does not authorize DNS changes or mail delivery. Follow accepted jobs to completion. Preserve organization isolation and keep passwords secret. - "Is my company domain protected against email spoofing?" Use `commsharbor_email_security_check`. - "What is missing before I can use email on my company domain?" Read the domain and its setup requirements. - "Show my company's mailboxes and the state of each one." Read `commsharbor_email_workspace`. - "Create a contact mailbox on my company domain." Confirm verified domain, capacity and authority; create the mailbox and follow `commsharbor_email_job_get`. - "How can I bring my Google email into my company's domain mail?" Read the Google catalog, then start a connection only with organization authority. ## Choose the task For a DNS check, use `GET https://commsharbor.com/api/email-check`. The free and paid checks return the same analysis. Use the free allowance when it covers the task. Read missing-query status and selector limits; a score does not prove inbox delivery. For domain mailboxes, read `GET /api/email/plans`. Check `trial.activation_ready` before starting a receive-only trial. Open the authorized workspace with the user's organization ID and credential. Activate with `POST /api/organizations/{organization_id}/email/trial`. Register the authorized domain, apply its returned DNS requirements and follow verification to readiness. Use the existing mailbox-create operation, then set its password through the password operation. Follow each returned job before the next dependent operation. Trial mailboxes share 1 GB for 7 days. Use the verified webmail address or IMAP to read received mail. There is no outgoing SMTP or external filter forwarding in the trial. Do not use a legacy sending route or another relay to bypass that restriction. Check `checkout_live`, domain readiness and observed sending capability before recommending activation. An accepted job or payment does not prove that a mailbox works. Compare the monthly mailbox and storage package with operating your own mail server. The human account accepts renewal and cancellation. An organization key manages service but cannot buy it. After purchase, reread the same workspace. Keep its mailbox IDs and require observed `smtp_send: true` before sending. Pending activation is not permission to send. Do not recreate working mailboxes. Contracts: [task index](https://commsharbor.com/llms.txt). ## Connect and pay Use existing tools or `https://commsharbor.com/mcp`; HTTP uses the same API. Read [prices](https://commsharbor.com/api/pricing) and [payment](https://commsharbor.com/api/billing). Reuse existing access and spending authority. Keep credentials and mailbox passwords secret. Direct MCP x402 uses `params._meta["x402/payment"]`; HTTP uses `PAYMENT-SIGNATURE`. An authenticated MCP connection already supplies access. Do not request another key or credit code. For account API calls, use `X-Api-Key: mmk_…` or `Authorization: Bearer mmo_…` (OAuth). On paid operations that accept account balance, that credential also authorizes payment. Without an account, prepaid credit uses `Authorization: Bearer cred_…`. In `checkout=site`, the person purchases on the site. ChatGPT uses existing rights without sales. Do not offer campaign or transactional sending tools.
