Nothing serious here today
Today is the operative word: we check Letterhead every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Read directly from the server with tools/list, grouped by what they act on.
If a tool disappears, we record the date.
doc
doc_create
Call this tool to write a real .docx file from structured sections. Returns the file path, the number of blocks written and the layout used. Free and unlimited.
doc_delete_upload
Delete one document uploaded for your token: name is the name it was uploaded under, without .docx. doc_files lists them. A name nothing is stored under is refused and nothing is deleted.
doc_files
List the documents uploaded for your token, with their sizes.
doc_fill_template
Call this tool to replace {{placeholders}} in a .docx and write a new file, reporting what was filled, unfilled or ignored. Call it with no values to list them. Free: templates up to 10 placeholders.
doc_from_markdown
Call this tool to turn markdown into a .docx, returning the file and a count of blocks by type. Headings, lists, GFM tables and code fences are honoured. Empty markdown is refused, and so is overwriting without the flag.
doc_read
Call this tool to extract the text of an existing .docx. Returns an outline of the headings and the full text in document order, or the block structure. Free and unlimited.
doc_to_html
Call this tool to convert a .docx to semantic HTML you can open in a browser and print to PDF. Returns the path of the .html file. This is the supported PDF route; no PDF is rendered here. Free and unlimited.
doc_upload
Send an existing Word document to this hosted endpoint. There is no filesystem here, so instead of a path you upload the file once with doc_upload and then pass its name as `path` to doc_read, doc_to_html and doc_fill_template. Give exactly one of docx_base64 or url. url: fetch a public file instead of pasting base64 (recommended above about 10 KB): a 13 KB base64 paste can take minutes to write out, while a url costs one line and the fetch happens here (10 second timeout, at most 3 redirects, public http(s) hosts only, 2 MB cap). Uploads are kept for your token between calls; doc_read and doc_fill_template also take docx_base64 directly; that file is stored under the name you give (default 'inline' / 'template') and can be removed with doc_delete_upload. Documents this server writes come back as a download link valid for one hour.
license
license_activate
Turn Pro on for this connection with key, an MCPL1.<payload>.<signature> issued at checkout for this server or the bundle. Data under your token stays; a wrong or expired key changes nothing. license_status confirms it.
license_status
Report this endpoint's licence state for your token as JSON: the product, the tier free or pro, why it is not Pro, and the checkout URL. Call it to explain a free-tier refusal. No arguments, nothing changes.
proposal
proposal_create
Call this tool to produce a client-ready .docx proposal from summary, scope, deliverables, timeline, price and terms. Returns the reference, the total and the file path. Free tier: 3 proposals or contracts per month.
proposal_update
Rewrite an existing proposal in place from its reference. Only the fields you pass change; the rest comes from the data stored at creation. Returns the fields that changed and the file path.
business
business_set
Store the sender details printed on every proposal, contract and letter, plus the currency, VAT, terms and prefix defaults. It writes the SAME shared profile as the invoice server's business_set.
contract
contract_create
Call this tool to produce a freelance service agreement .docx. Returns the reference, the fee and the file path. It is a template skeleton for a lawyer to review, not legal advice. Free tier: 3 agreements per month.

Letterhead — questions
Answers built from our own checks of this server.
What can Letterhead do?
It exposes 14 tools, read directly from the server on our last check. Among them: business_set, contract_create, doc_create, doc_delete_upload, doc_files, doc_fill_template and 8 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 →
What is Letterhead mostly used for?
Its tools cluster around doc, license and proposal. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.
Is Letterhead working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 87 of 87 checks got a reply (100.0%), average response time 256 ms. The bar chart above shows every period we have measured.
How do I connect Letterhead?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Letterhead need an API key?
No. Letterhead completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 14 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Letterhead?
It answers our handshake in 256 ms on average, which is faster than 58% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is Letterhead open source?
The code is open source: it is published under the MIT licence, written in JavaScript and 2 stars on GitHub. The licence covers the code in the repository, not the hosted service at mcp.zovo.one, which runs on its operator's own terms.
