Available tools 7

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

signature

create_signature

Builds the email-safe HTML signature (table + inline styles, the same bytes as prosignature.co/email-signature-generator) for one person. Returns html, a plain-text version, an edit_url that opens the generator prefilled, and install steps for Gmail, Outlook and Apple Mail. The output is the free plan: four layouts, six accent colours, no logo or photo, and a small clickable "Created with ProSignature" credit line under the signature (Pro removes it). Nothing is installed or stored.

get_signature_playbook

The rules professional signatures follow, what each of the 13 templates looks like, the recommended templates / fields / CTA / banners for 8 departments and 18 sectors, and the Gmail / Outlook / Apple Mail pitfalls that break signatures — with what ProSignature already handles and what no tool can automate. Pass department and/or sector for one profile.

design

design_signatures

Start here when a user asks for an email signature. From what you already know about them (person, company, brand colour, logo URL, website, socials, department, sector, team size) it builds 3–4 professional designs with the app's 13 templates (each a different angle: clean, call-to-action, campaign banner, sign-off), chosen by the playbook for that role and sector. Returns ONE preview_url that renders all of them side by side in the user's browser (data in the URL fragment, nothing stored), a claim_url per design (opens the ProSignature app with that design loaded; the human signs up free and upgrades there), the free do-it-yourself version as paste-ready HTML, the three ways to install with prices from pricing.json, and present_to_user: a short message you can adapt. Nothing is fetched from logo_url server-side.

facts

get_facts

What ProSignature is, the free plan and its credit line, Pro and Teams prices (verified 2026-10-18), how Gmail and Google Workspace installs work per person, personal links for employees, what the product is NOT (no mail-flow enforcement, no Microsoft 365 sync, no analytics), and where the docs, OpenAPI and pricing.json are.

install

get_install_steps

How a signature from create_signature gets into a mail client, honestly: Gmail web (paste, or the sendAs PATCH with gmail.settings.basic — new mail only), Gmail mobile, Outlook (copy-paste only, no directory sync), Apple Mail, iPhone. The free Chrome extension (auto-updates, covers replies) needs the human to sign up first.

layouts

list_layouts

The four signature layouts (id, name, what it looks like) and the six accent colours the generator offers.

quote

quote_price

List price for Pro (one person) or Teams (per person, 5-person minimum, no platform fee) for a number of people, billed yearly or monthly, computed from the rules in https://prosignature.co/pricing.json (verified 2026-10-18). The admin counts as one of the people. Free plan: $0, credit line. This is a quote, not a checkout: the human pays in the app after signing up.

ProSignature email signatures — questions

Answers built from our own checks of this server.

What can ProSignature email signatures do?

It exposes 7 tools, read directly from the server on our last check. Among them: create_signature, design_signatures, get_facts, get_install_steps, get_signature_playbook, list_layouts and 1 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 ProSignature email signatures working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 702 ms. The bar chart above shows every period we have measured.

How do I connect ProSignature email signatures?

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 ProSignature email signatures need an API key?

No. ProSignature email signatures completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 7 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is ProSignature email signatures?

It answers our handshake in 702 ms on average, which is faster than 14% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
