@deliveriq/mcp

Official MCP (Model Context Protocol) server for the DeliverIQ email verification API by MiN8T. Provides 12 tools for AI agents in Claude Desktop, Claude Code, Cursor, and any other MCP-compatible client.

Installation

No separate install step needed — npx -y @deliveriq/mcp will fetch and run the server on demand.

Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "deliveriq": {
      "command": "npx",
      "args": ["-y", "@deliveriq/mcp"],
      "env": {
        "DELIVERIQ_API_KEY": "lc_your_api_key"
      }
    }
  }
}

Restart Claude Desktop. You should see the 12 DeliverIQ tools available.

Claude Code
claude mcp add deliveriq npx -y @deliveriq/mcp \
  -e DELIVERIQ_API_KEY=lc_your_api_key
Cursor

Add to .cursor/mcp.json:

{
  "mcpServers": {
    "deliveriq": {
      "command": "npx",
      "args": ["-y", "@deliveriq/mcp"],
      "env": {

Why MCP?

Email deliverability is one of those problems where the right answer needs 6–8 API calls (verify → reputation → DMARC → blocklist → infrastructure → ...). Letting Claude orchestrate these as tools is ~10× more useful than shipping another dashboard — the model can plan, branch on results, and explain the verdict in plain English.
