About Disify
Disify is an MCP server for email and domain risk checks, intended for applications that need to screen addresses. It validates address syntax, DNS records, and disposable-email signals, and can use an optional Disify key.
Key features
- 01Validate email format and DNS
- 02Detect disposable email and aliases
- 03Assess disposable-domain risk
- 04Return confidence scores and signals
Use cases
- 01Screen sign-up email addresses
- 02Check domains for temporary email use
MCP support
Exposes `validate_email` and `check_domain` as MCP tools. It can run locally over stdio or connect through the Pipeworx gateway; gateway endpoints also include shared Pipeworx meta-tools.
Configuration
Remote servers need no local install. Pick your client, then copy the config or install in one click.

Servers that need sign-in will prompt on first connect.

Disify MCP — wraps the Disify API (anonymous tier + BYO key)
Part of Pipeworx — an MCP gateway connecting AI agents to 1878+ live data sources. This is an independent, unofficial integration — not affiliated with, endorsed by, or published by the upstream provider.
Tools
| Tool | Description |
|---|---|
validate_email | Verify an email address is properly formatted, has valid DNS records, and isn't disposable or an alias. Returns validation status, a 0-100 confidence score and the signals behind it. Pass your own Disify key as _apiKey — the keyless anonymous quota is shared and usually spent. |
check_domain | Check if a domain is associated with disposable or temporary email services. Returns risk assessment, a 0-100 confidence score and the signals behind it. Pass your own Disify key as _apiKey — the keyless anonymous quota is shared and usually spent. |
Quick Start
Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):
{
"mcpServers": {
"disify": {
"url": "https://gateway.pipeworx.io/disify/mcp"
}
}
}
What this endpoint actually serves
tools/list at https://gateway.pipeworx.io/disify/mcp returns the tools in the table
above plus the shared Pipeworx meta-tools — ask_pipeworx,
discover_tools, search_within, remember/recall and the rest of the
gateway-wide set. So the tool count you see is larger than this table: a
single-pack endpoint currently lists roughly 30 shared tools alongside the
pack's own. The connection's initialize response states its exact scope, and
is the authoritative answer for a given day.
This is deliberate, not multiplexing by accident. The meta-tools are what let a
scoped connection answer a question this pack does not cover — via
ask_pipeworx, which routes across the whole catalog — without you adding a
second MCP server. There is currently no way to mount a pack endpoint without
them; if the extra schemas cost you more context than the routing is worth,
connect to the full gateway once rather than to several pack endpoints.
Or connect to the full Pipeworx gateway to get every pack's tools listed directly, instead of just this one's:
{
"mcpServers": {
"pipeworx": {
"url": "https://gateway.pipeworx.io/mcp"
}
}
}
Both URLs reach the same gateway and the same 1878+ data sources. The
only difference is which pack's tools are listed directly; ask_pipeworx
reaches all of them from either one.
No MCP client? Call it over HTTP
curl -X POST https://gateway.pipeworx.io/v1/tools/validate_email \
-H 'Content-Type: application/json' \
-d '{"email":"[email protected]"}'
No account needed for the first calls. Inspect any tool: GET https://gateway.pipeworx.io/v1/tools/validate_email. Find one: POST https://gateway.pipeworx.io/v1/tools/search_packs with {"query":"..."}.
Standalone (no gateway account)
This package also runs as a local stdio MCP server — no Pipeworx account, no gateway round-trip:
{
"mcpServers": {
"disify": {
"command": "npx",
"args": ["-y", "@pipeworx/mcp-disify"]
}
}
}
Or run it directly to confirm it starts:
npx -y @pipeworx/mcp-disify
It speaks MCP over stdin/stdout and answers initialize/tools/list/tools/call
for only this pack's tools — none of the shared meta-tools the gateway
connection above adds. Same source, same tools, no ask_pipeworx routing.
Using with ask_pipeworx
Instead of calling tools directly, you can ask questions in plain English — this works on the pack endpoint above as well as on the full gateway:
ask_pipeworx({ question: "your question about Disify data" })
The gateway picks the right tool and fills the arguments automatically.

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
