Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Send documents for e-signature, track who signed and save sealed PDFs with PenlyDoc.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 1 of 1 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.
You need to fill in: PENLY_API_KEY
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Let an AI assistant send documents for e-signature with PenlyDoc and follow them: "Send the lease to Mia Novak from the Residential lease template, rent 950 EUR", "Who still has to sign order 42?", "Save the signed contract to ./signed".
It is a Model Context Protocol server that runs on your computer (stdio) and talks to the PenlyDoc REST API with your organisation's API key. Works with any MCP client.

"mcpServers": { "penlydoc": { "command": "npx", "args": ["-y", "penlydoc-mcp"], "env": { "PENLY_API_KEY": "sk_…" } } } }
Node.js 18.17 or newer is needed. PENLY_URL points the server at another PenlyDoc instance (default https://penlydoc.com).
Treat the API key like a password: it can send documents in your organisation's name. Give the assistant a key of its own, so you can revoke it in the console without touching your other integrations.
| Tool | What it does | Side effects |
|---|---|---|
get_organisation | Which organisation the key belongs to, sending limit | none |
list_templates | Templates with their roles and data keys | none |
send_from_template | Create a document from a template; send: true e-mails the people | e-mails real people |
send_document | Upload local PDFs or photos and create a document; boxes from {{sig:1}} tags or coordinates | e-mails real people when send: true |
list_documents | Documents with status and who has signed; filter by status or your reference | none |
get_document | One document: each person, opened, signed or declined, and when | none |
get_history | Hash-chained history with times and IP addresses | none |
send_draft | Send a draft | e-mails real people |
send_reminder | Remind everyone whose turn it is | e-mails real people |
cancel_document | Void a document that is still being signed | cannot be undone |
create_signing_link | One-hour link for an embedded signer | the link signs as that person |
download_signed_pdf | Save the sealed PDF of a completed document to a file | writes a local file (never overwrites) |
verify_pdf | Check a signed PDF: seal intact, who signed | none, no key needed |
The server tells the assistant to confirm people, e-mail addresses and documents with you before anything is sent. Most MCP clients also ask you before each tool call; keep that on for the tools that e-mail people.
