Commsharbor tools (32, 25 write)

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

Events contain only an opaque change ID. DNS checks run in the private backend, with a 24-hour deadline and a visible resume action after pause.
commsharbor_healthFree
Read deployment health and build. Smoke tests wait for their own commit to appear here instead of racing edge propagation.
commsharbor_logoutFree
Revoke the current session. Bootstrap/CSRF must belong to this browser and session. Other product sessions remain active.
commsharbor_meFree
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_organization_getFree
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_platform_contextFree
Confirm the caller's platform role. Tenant ownership grants nothing here: platform access is a separate, explicit grant.

What the publisher says

From the Commsharbor repository's README, as published. We do not edit it. Read it on GitHub

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."

commsharboremailplans reads the public plans and storage allowances.
commsharboremailworkspace reads an authorized organization's workspace.
commsharboremaildomain_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.
