api record

SignatureForever builds email signatures that survive real email clients, and audits ones you already have. Start with check_email_signature when the user already has a signature and something looks broken: it names the exact rule, the clients it breaks in, and the fix. Use email_client_compatibility_matrix when you need to answer what a given email client supports. Use create_email_signature to produce ready-to-paste HTML. Free signatures carry one small credit line at the bottom; get_pricing explains how to remove it and what else the paid tiers include.

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

    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.

    {
      "type": "object",
      "properties": {}
    }
    arguments 4 lines
  • email_client_compatibility_matrix unknown never probed

    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, margins and image sizing. Each row says yes/no/partial for seven real clients and explains what goes wrong. Use it to answer questions about email HTML support.

    mcp-tool

    {
      "type": "object",
      "properties": {
        "feature": {
          "type": "string",
          "description": "Optional. Filter to rows whose feature name contains this text, e.g. 'base64' or 'font'."
        }
      }
    }
    arguments 9 lines
  • list_signature_templates unknown never probed

    The signature layouts you can pass to create_email_signature, with what each one is good for and its width in pixels.

    mcp-tool

    {
      "type": "object",
      "properties": {}
    }
    arguments 4 lines
  • check_email_signature unknown never probed

    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 fix it. Use this when a signature renders wrong, images do not show, layout collapses in Outlook, or before sending a signature to a client. Free, no account needed.

    mcp-tool

    {
      "type": "object",
      "required": [
        "html"
      ],
      "properties": {
        "html": {
          "type": "string",
          "description": "The full HTML of the email signature to audit."
        }
      }
    }
    arguments 12 lines
  • create_email_signature unknown never probed

    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 absolute URL (never base64, which Gmail refuses to render). The free result carries one small credit line at the bottom; get_pricing explains how to remove it.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we know
card completeness
90%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
