Verifly MCP Server

Agent-native email verification over the Model Context Protocol. This server gives any MCP client — Cline, Claude Desktop, Claude Code, Cursor, Windsurf — a clean set of tools to verify email addresses, clean lists, run async bulk jobs, and manage a Verifly account, all without writing a single raw HTTP call.

It is built for autonomous workflows: an agent can self-register for an API key, verify a lead before sending, deduplicate and scrub an import list, kick off a bulk job and poll it to completion, and check its own credits and usage — end to end.

Tools

15 tools cover the full Verifly workflow:

Tool	What it does
`verify_email`	Verify a single address in real time (verdict, reason, flags, send/reject recommendation, credits)
`verify_batch`	Verify a list synchronously (per-address verdicts; best for up to a few hundred)
`clean_email_list`	Dedupe + drop invalid syntax, disposable, and role addresses from a list
`extract_emails`	Pull every email address out of free-form text (notes, signatures, pasted docs)
`check_domain_health`	MX / SPF / DMARC records + an overall health score for a domain
`get_credits`	Remaining verification credits + recent usage (free, no credits)
`submit_bulk`	Submit an async bulk verification job for large lists (returns a `job_id`; optional `webhook_url`)
`get_job_status`	Status + progress of a bulk job
`get_job_results`	Per-address results of a completed bulk job
`list_jobs`	List the account's bulk jobs (filter by status, paginate)
`get_usage`	Detailed usage statistics for a period (day / week / month)
`get_account`	Account profile: email, company, credits, plan, key count (free)
`get_packages`	List the credit packages available to purchase
`buy_credits`	Start a credit-package purchase and return a checkout link
`register_account`	Self-onboard a brand-new account; returns an `api_key` shown once

Authentication

Get an API key from https://verifly.email (or have an agent self-register with register_account). The server reads the key from the VERIFLY_API_KEY environment variable. Every Verifly request is authenticated with Authorization: Bearer <key>.

The hosted HTTP transport also accepts a per-request Authorization: Bearer <key> header (which overrides the env var), so each caller can supply their own key.

Install (local, stdio) — recommended for Cline

Terminal

npx -y verifly-mcp-server

or install it globally:

Terminal

npm install -g verifly-mcp-server
verifly-mcp-server

Client config

Add this to your MCP client config (Cline: cline_mcp_settings.json; Claude Desktop: claude_desktop_config.json):

config.json

{
  "mcpServers": {
    "verifly": {
      "command": "npx",
      "args": ["-y", "verifly-mcp-server"],
      "env": {
        "VERIFLY_API_KEY": "vf_your_api_key"
      }
    }
  }
}

That's the whole setup — no build step, no clone. See llms-install.md for an agent-followable install guide.

Hosted Streamable-HTTP transport

If you'd rather not run anything locally, Verifly hosts the same server as a remote Streamable-HTTP endpoint:

Code

https://verifly.email/mcp

Point any Streamable-HTTP-capable MCP client at that URL and pass your key as an Authorization: Bearer <key> header. Example raw call:

Terminal

curl -s -X POST https://verifly.email/mcp \
  -H "Content-Type: application/json" \
  -H "Accept: application/json, text/event-stream" \
  -H "Authorization: Bearer vf_your_api_key" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call",
       "params":{"name":"verify_email","arguments":{"email":"lead@example.com"}}}'

Self-hosting the HTTP transport

bash

PORT=8787 VERIFLY_API_KEY=vf_your_api_key node src/http.js
# or: PORT=8787 VERIFLY_API_KEY=vf_... npm run start:http

Var	Default	Purpose
`PORT`	`8787`	Listen port
`HOST`	`0.0.0.0`	Bind address
`MCP_PATH`	`/mcp`	Path the MCP endpoint is served on
`VERIFLY_API_KEY`	—	Fallback key when a request sends no `Authorization` header
`VERIFLY_BASE_URL`	`https://verifly.email`	API base override

MCP endpoint: POST {MCP_PATH} (stateless Streamable HTTP).
Health check: GET /healthz → {"ok":true}.

Test

bash

VERIFLY_API_KEY=vf_your_api_key npm run test:e2e

Drives the stdio server through the MCP protocol and performs a real verify_email + get_credits call against the live API.
