Overview

Description from the maker (original English)

Domain email and webmail: set up domains, mailboxes and aliases, and check DNS verification.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

What it can do

Tool names and descriptions exactly as the server reported them on Nov 8, 2026. The maker wrote them, not us; we show them as plain text.

  • commsharbor_health

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

  • commsharbor_logout

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

  • 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}`.

  • 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.

  • 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.

  • commsharbor_audit

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

  • commsharbor_platform_context

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

  • commsharbor_billing_catalog

    Read plans, prices and x402 network.

  • commsharbor_email_google_catalog

    Read authorized Google metadata. This does not prove DNS ownership. Requires the owner's account session; an organization key cannot authorize Google access. Requires an account session in this organization. Reads site metadata only. Google access and refresh tokens remain encryp

    Start five-minute Google consent with PKCE. Return an authorization URL. Signing in does not grant this access. Requires the owner's account session; an organization key cannot authorize Google access. Requires an account session in this organization. Reads site metadata only. Go

  • commsharbor_email_google_resolve

    Resolve website addresses for up to 20 selected Analytics properties. Search Console does not use this route. Requires the owner's account session; an organization key cannot authorize Google access. Requires an account session in this organization. Reads site metadata only. Goog

  • commsharbor_email_google_disconnect

    Remove this product's saved Google connection and pending consent. Existing email and service resources remain intact. Requires the owner's account session; an organization key cannot authorize Google access. Requires an account session in this organization. Reads site metadata o

  • commsharbor_email_domain_products_list

    Start the free receive-only Trial for 7 days, once per organization: 1 GB shared storage, unlimited mailboxes and no outgoing SMTP or external filter forwarding. No card, renewal or charge. After 7 days, writes without a paid plan answer 402 `email_trial_expired`. Requires a new

Common questions

Is Commsharbor safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.1) reached the registry 24 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: GitHub, Desktop Commander, Cloudflare MCP

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:

{

"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 contato@commsharbor.com 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.
