VerifiedSTDIODesktop only

Overview

Mailport's local MCP server; no sign-in required; STDIO.

No AI overview yet: these facts come from the registry entry and the server itself.

Installation

In SourceWeft

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

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

README

mailport

Gmail messages, threads and labels as MCP tools, talking to the Gmail API. mailport is a clean-room rebuild of the core surface of the Gmail reference MCP server, under a new name: fresh code written from the public Gmail API documentation, no copied branding.

Tools (core subset, 10)

list_messages, get_message, list_threads, get_thread, list_labels, send_message, create_draft, modify_message, trash_message, create_label.

Label update/delete, draft get/update/delete/send, message delete and batchModify, history, profile/settings/watch, and attachment downloads from the wider Gmail surface are not in this subset.

Setup

Set a Google OAuth access token:

bash
export GOOGLE_ACCESS_TOKEN=ya29....

Optionally override the API base with GMAIL_API_URL (default https://gmail.googleapis.com/gmail/v1). Without the token, every tool call fails with an error naming the missing variable.

CLI

bash
npx @reneturcios/mailport list_messages '{"query":"in:inbox","max_results":5}'npx @reneturcios/mailport mcp        # stdio MCP server

Each tool name is a subcommand taking one JSON object argument.

Score

50% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.

  • Tools listed15 pts

    Answer tools/list without a credential, or ship a package that starts in a sandbox without one.
