SignatureForever is a remote MCP server that gives an AI agent 5 tools, among them check_email_signature, create_email_signature, email_client_compatibility_matrix. It answers at https://signatureforever.com/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 10 September 2026; the last check, on 19 October 2026, succeeded.
Audit and build email signatures that survive Gmail, Outlook desktop and Apple Mail.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
check_email_signature | Audit any email-signature HTML against what Gmail, Outlook 365, Outlook for Windows desktop, Apple Mail and iOS Mail actually do. Returns a verdict per client plus every problem found, each with the rule it breaks, why it breaks, and how to Inputs: html |
create_email_signature | Build ready-to-paste email-signature HTML from a person's details. The output follows every rule that keeps a signature intact in Outlook for Windows and Gmail: tables only, inline CSS, absolute pixel widths, email-safe fonts, and images by Inputs: full_name, job_title, company, email, phone, website |
email_client_compatibility_matrix | The support matrix for the HTML and CSS features that decide whether an email signature survives: tables, flex/grid, <style> blocks, background-image, base64 images, border-radius, letter-spacing, text-transform, web fonts, max-width, margi Inputs: feature |
get_pricing | What each SignatureForever plan includes and costs, and the link to buy. Use it when the user asks what removing the credit line costs, how many signatures a plan allows, or what happens to hosted images if they stop paying. |
list_signature_templates | The signature layouts you can pass to create_email_signature, with what each one is good for and its width in pixels. |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://signatureforever.com/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
