Gmail Multi MCP

blackwings-dev · MCP server(filed by default)

Gmail Multi MCP makes the Google account a parameter, so your AI assistant can work across work, billing and personal accounts in one request. Leave the account out and it searches every connected mailbox, Drive, calendar and address book. It can read, draft, send and label mail, search and share Drive files, manage events and find a time free on all calendars. You create your own Google Cloud project and OAuth client, and while that app is in testing each account must be reconnected every seven days.

Written by ooruby from the README of @blackwings-dev/gmail-multi-mcp 0.3.0.

Not claimed by its maker. Is this yours? Prove it and answer the findings

Why it's useful

One assistant can see all your Google accounts together, so questions that span a work and a personal account no longer need switching between connectors.

What you could do with it

  1. 1Ask for unread invoices this week across your work, billing and personal mailboxes in one question.
  2. 2Find a free hour that is open on all of your calendars, then plan around it.
  3. 3Search every Drive you have connected, including shared drives, for a file by name.

Written from its documentation: what it says it can do, not what our checks found.

Maintenance

Not measured

No release date is on record for this package yet. The nightly publisher check records one as it reaches each npm package, about once every ten nights.

Release activity only: it says nothing about quality or safety, and a finished small package can be fine without releases. How it is measured

How far this has been checked

Static scanned

What it establishes
Its published package, or for a hosted server its source repository at a recorded commit, was read file by file, without running it, by every check in our current scan.
What it does not
How it behaves when it runs, or anything the scan does not read yet: several rubric checks, the repository's history, and compiled code in folders named dist or build. For a hosted server, that the endpoint runs the code that was read. The ooruby Index sets out exactly what was read.
Exactly what was read
Version 0.3.0, the file with digest sha512-re9Gra8FclHixbciH4AFZUAiN7v79WjWD4+MpcvTc3m5b4GlgDHIvsyxo0gUmh22Httu846Gw7v5+EWBWaCEdg==, as the registry publishes it. A published version cannot be replaced, so this names the same bytes for anyone who checks.
Authentication
Runs locally. No hosted endpoint is listed for this package. You run it on your own machine, so there is no endpoint of ours to authenticate against.
How the rungs work

Adding it

Paste this into your client's MCP configuration.

{
  "mcpServers": {
    "gmail-multi-mcp": {
      "command": "npx",

        "-y",
        "@blackwings-dev/gmail-multi-mcp@0.3.0"
      ]
    }
  }
}

Or run it directly.

npx -y @blackwings-dev/gmail-multi-mcp@0.3.0

Pinned to 0.3.0, which is the version the findings above were found in. Drop the version to take whatever is newest, and the report on this page stops describing what you installed.

The badge, if this is your listing

It renders the current rung (static scanned) and links back here, where what that does and does not establish is one click away. It updates itself as the evidence deepens.
