Overview

AI-generated overview

Remote MCP server for CommsHarbor domain email: read the workspace, set up domains, mailboxes and aliases, and check DNS verification.

What you can do
Read account, organization and platform context, plus deployment health and tenant audit events, and revoke the current session with logout. Read the email workspace, DNS progress and recent jobs, and fetch a single durable job. Register domains, read DNS records and readiness, queue ownership/DNS/certificate checks, and request assisted DNS setup. Create, update, suspend and resume mailboxes, set mailbox passwords, and manage aliases and their destinations. Connect, resolve and disconnect Google metadata, associate PageAudit and HookPulse with a domain, activate the receive-only trial, and request included services. Run a free public DNS email security check (SPF, DKIM, DMARC, MX, MTA-STS,
When to use it
Use it when an assistant should help run domain email for an organization: checking a domain before purchase, walking through DNS verification, creating or adjusting mailboxes and aliases, or auditing a domain's SPF, DKIM and DMARC posture.
Requirements
A remote Streamable HTTP endpoint; no local program is needed. Public discovery and the DNS security check need no account. Workspace operations need organization access, an organization API key sent in the X-Api-Key header, and the organization_id requested by the tool. Google tools need the owner's account session.
Before you install
Workspace tools create, change, suspend and resume mailboxes and aliases, set mailbox passwords, and register domains, so writes affect real email. Keep the API key in the client's secret storage and never commit it to configuration. The documented connection disables payment transactions through the assistant, but plans and trials still involve the hosted service's terms and cost. Mailbox passwords and message content are not returned by workspace reads.

Installation

In SourceWeft

  1. Open Commsharbor in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.commsharbor%2Fcommsharbor/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

README

CommsHarbor MCP server

CommsHarbor provides email for your domain, with webmail, IMAP and SMTP. Its remote MCP server helps an assistant read the email workspace, prepare domain setup, check DNS verification, and manage authorized mailboxes and aliases. This repository contains the connection settings and a user skill. The hosted service runs at commsharbor.com.

Configure

The server uses Streamable HTTP. No local program is required. Add this to .vscode/mcp.json for GitHub Copilot in VS Code:

json
{  "servers": {    "commsharbor": {      "type": "http",      "url": "https://commsharbor.com/mcp?checkout=site"    }  }}

For Cursor, use the same entry under mcpServers in .cursor/mcp.json. For other clients, select an HTTP server and enter the URL above. The official registry entry is com.commsharbor/commsharbor.

Use

Start with: "Show the available CommsHarbor email plans."

  • commsharbor_email_plans reads the public plans and storage allowances.
  • commsharbor_email_workspace reads an authorized organization's workspace.
  • commsharbor_email_domain_setup checks a domain before purchase without creating a charge.
  • Other authorized tools create mailboxes and aliases, verify domains and read setup jobs.

Public discovery requires no account. Workspace operations require organization access. Use an organization API key through the client's secret storage and the X-Api-Key header. Supply the organization_id requested by the tool. Never commit a key to the client configuration. Read the API contract for each tool's required fields and permissions.

Access and cost

Create the account and select the email service on the website. The receive-only trial and sending plans have different permissions. The connection above disables payment transactions through the assistant. Mailbox passwords and message content are not returned by workspace reads. Campaigns and transactional sending APIs are not part of the current offer.

Documentation and support

Send support requests to [email protected] or open an issue here. The files in this repository use the MIT-0 license. The hosted service has separate terms. Its source code is not included.

Tools

commsharbor_health

Commsharbor health

Read deployment health and build. Smoke tests wait for their own commit to appear here instead of racing edge propagation.

Takes no parameters.

commsharbor_logout

Commsharbor logout

Revoke the current session. Bootstrap/CSRF must belong to this browser and session. Other product sessions remain active.

Takes no parameters.

commsharbor_me

Commsharbor me

Read the current account profile and platform role. `user.id` is the shared-account ID. Organizations are not listed here: they live in the shared account, which does not list them inside products yet — open a workspace by its ID with `GET /api/organizations/{organization_id}`.

Takes no parameters.

commsharbor_context

Commsharbor context

Resolve the active organization identity. Read this before a write when you are not certain which tenant is active. Guessing is how data lands in the wrong organization. An organization API key answers `kind: api_key` with its scopes.

Takes no parameters.

commsharbor_organization_get

Commsharbor organization get

Open an organization by id: name, your role and the CommsHarbor plan. This is how a workspace is opened. Name and role come from the shared account (null with an organization API key, which carries neither); the plan is the organization's global entitlement in CommsHarbor.

Parametersorganization_idrequired

commsharbor_audit

Commsharbor audit

List tenant audit events. Audit records are never rewritten and never carry recipient PII.

Parameterscursororganization_idrequired

commsharbor_platform_context

Commsharbor platform context

Confirm the caller's platform role. Tenant ownership grants nothing here: platform access is a separate, explicit grant.

Commsharbor email security check

Check whether someone can send email as a domain: SPF, DKIM in common selectors, DMARC, MX, MTA-STS and BIMI, with a 0-100 score and the fixes, most severe first. Public DNS only. Free, no account. The same domain is served from memory for 10 minutes. A network can run 30 new checks per day. DKIM is looked up in common selectors only; `dkim_not_found` does not prove that no key exists. `incomplete: true` means a DNS answer failed and the score can be lower than the real one; `unread` names those parts, and a failed query never becomes a missing finding.

Parametersdomainrequired

commsharbor_brazil_email_report

Commsharbor brazil email report

Read the monthly Brazil email security report: how many domains of city halls, state and federal government, banks and listed companies reject fake email (DMARC p=reject) and how they end SPF. Totals only, public DNS. Free, no account. Public DNS only, read once a month. The sample is built from Brazil's open company registry (Receita Federal, the email of each active head office) and the CVM register of listed companies. Only totals: no domain is listed. A share is `count / (com_mx - dmarc.nao_lido)`; domains without MX are left out. Only the DMARC policy classifies; SPF is counted but does not change the class. `percent` rounds each group to 100 by the largest remainder, the same rule as the page.

Takes no parameters.
