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.

    Verify this mcp-narrow connection, authenticated workspace principal, environment, granted scopes and available tool permissions. Anonymous checks reveal no private workspace data. No charge, mailing, funding or credential disclosure.

    No charge. Read stored job status and tracking by id with OAuth or a key for the owning workspace. Does not itself refresh mailing status. Inspect the body for not_found.

  • list_jobs

    No charge. List recent jobs in the authenticated workspace; default 20, maximum 100. Pass the last returned job id as before to continue. MCP structuredContent returns {jobs:[...]}; the text content retains the JSON array for existing clients.

    Calculate a public USD physical-mail quote from mail class, page count, recipient count, print options and optional coupon. No account or charge required; an authenticated request also reports the existing workspace balance. A quote does not send mail, initiate checkout or fund a

  • preview_product_quote

    Download a saved quote's exact artwork PDF. All small and double-sided postcards include the selected recipient's illustrative address side; postage placement may vary. Other products return stored print artwork. Review before send_product_quote; reading never changes the quote o

  • list_cover_sheets

    List reusable workspace cover-sheet designs and versions, plus defaultDesign matching the website's Reset defaults button. To reset a local draft, replace its design with defaultDesign; this read never changes saved presets. Render to preview, then save_cover_sheet only if the us

  • get_letter_quote

    Read a saved standard-mail quote, its exact PDF and send outcome. No charge or submission. Use after interruption; completed quotes cannot be sent again. Quote access is bound to the account, endpoint and environment. Guest IDs are private bearer capabilities.

Common questions

Is DirectMailAmerica — Narrow safe?

It passed 2 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 (2.4.0) reached the registry 2 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?
