Available tools 8

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

order

create_order

Create and pay for a Premier Letters order — a real, handwritten letter mailed via USPS. Requires a Premier Letters API key. Use get_pricing or preview_letter first to confirm the price. For payment, either "card_on_file" charges the caller's saved card immediately, or "checkout_session" returns a checkout_url for the human to complete payment in a browser.

get_order_status

Get an order's status, delivery/tracking summary, and per-recipient mail status.

handwriting

list_handwriting_styles

List available handwriting styles (fonts) for a letter order. Use the returned "id" as options.handwriting_style / handwriting_style when creating an order or previewing.

orders

list_orders

List the authenticated user's recent orders.

preview

preview_letter

Render a preview of a handwritten letter (as an SVG image) and get its price, before creating an order. Does not save anything.

pricing

get_pricing

Get a live price quote for a Premier Letters order. Pass char_count (or letter_count for a rough estimate) plus optional mailing_option and paper_type to get a per-piece and total price, in cents. No account needed.

templates

list_templates

List the authenticated user's saved letter templates.

verify

verify_address

Verify and standardize a US mailing address via USPS. Use before create_order to catch typos and get the USPS-standardized form.

Premier Letters — questions

Answers built from our own checks of this server.

What can Premier Letters do?

It exposes 8 tools, read directly from the server on our last check. Among them: create_order, get_order_status, get_pricing, list_handwriting_styles, list_orders, list_templates and 2 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Premier Letters working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 28 of 54 checks got a reply (51.9%), average response time 438 ms. The bar chart above shows every period we have measured.

The registry lists Premier Letters as active — why does it not respond?

The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.

How do I connect Premier Letters?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Premier Letters need an API key?

No. Premier Letters completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 8 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Premier Letters?

It answers our handshake in 438 ms on average, which is faster than 36% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
