# Verifox MCP Server
[](https://smithery.ai/servers/verifox-ai/email-verifier)
MCP (Model Context Protocol) server that gives Claude and other AI assistants the **Verifox** API — **verify email deliverability** and **find business emails**, both single and in bulk.
## Quick start (published package)
Add to your Claude Desktop config (`~/Library/Application Support/Claude/claude_desktop_config.json`) or Claude Code MCP config — no install needed, `npx` fetches it:
```json
{
"mcpServers": {
"verifox": {
"command": "npx",
"args": ["-y", "verifox-mcp"],
"env": {
"VERIFOX_API_KEY": "foxkey_your_key_here"
}
}
}
}
```
Get a free API key (1,000 credits) at **https://verifox.ai/dashboard/api**. Restart Claude Desktop and ask it to "verify these emails".
## Tools
| Tool | Does | Credits |
| --------------- | --------------------------------------------------------------------------------------- | ------------ |
| `verify_email` | Verify ONE email — SMTP deliverability, catch-all, disposable, role, free + 0-100 score | 1 / email |
| `verify_emails` | Bulk-verify a LIST — submits, waits, returns one result per email | 1 / email |
| `find_email` | Find ONE business email from name + company domain (best match or not_found) | 10 / find |
| `find_emails` | Bulk-find emails for a LIST of contacts (name + domain each) | 10 / contact |
| `get_credits` | Check the account's remaining Fox Credit balance | free |
| `get_job` | Poll a long-running `verify_emails` / `find_email` / `find_emails` job for results | — |
Verify and find are async for large lists: the bulk tools wait ~55s inline, and hand back a `jobId` to finish via `get_job` if a job runs longer. Cached verifications cost 0 credits.
## Local development
Run straight from source with Bun (no build):
```bash
cd mcp
bun install
```
````json
{
"mcpServers": {
"verifox": {
"command": "bun",
"args": ["run", "/FULL/PATH/TO/Verifox-api/mcp/src/index.ts"],
"env": {
"VERIFOX_API_URL": "https://api.verifox.ai",
"VERIFOX_API_KEY": "foxkey_your_key_here"
```json
{
"mcpServers": {
"verifox": {
"command": "bun",
"args": ["run", "/FULL/PATH/TO/Verifox-api/mcp/src/index.ts"],
"env": {
"VERIFOX_API_URL": "https://api.verifox.ai",
"VERIFOX_API_KEY": "foxkey_your_key_here"
}
}
}
}
````
`VERIFOX_API_URL` defaults to `https://api.verifox.ai` when unset. For local
development against the API on port 8001, set it to `http://localhost:8001`.
### 3. Restart Claude Desktop
The tools will appear in Claude's tool list.
## Remote (HTTP) mode
The same server also runs as a **streamable-HTTP** MCP endpoint (for Smithery,
claude.ai connectors, and other remote MCP clients). Set `MCP_TRANSPORT=http`
(or a `PORT`) and it listens on `POST /mcp` with a `GET /health` check:
```bash
MCP_TRANSPORT=http PORT=8080 node dist/index.js
# or: docker build -t verifox-mcp . && docker run -p 8080:8080 verifox-mcp
```
In HTTP mode the Verifox API key is read **per request** from the
`Authorization: Bearer <foxkey>` header (also accepts `x-api-key` or `?api_key=`)
— so one hosted endpoint serves many users, each on their own credits.
## Usage Examples
In Claude Desktop, just ask:
- "Scan stripe.com for security issues"
- "Check if john@google.com is a valid email"
- "Score these emails: admin@stripe.com, test@mailinator.com, john.doe@microsoft.com"
- "Find the email for Patrick Collison at stripe.com"
- "Run OSINT on tesla.com — find subdomains and emails"
- "Test the email server for turnix.co"
- "Check DMARC policy for google.com"
## Environment Variables
| Variable | Default | Description |
| ----------------- | ------------------------ | -------------------------------------------------- |
| `VERIFOX_API_URL` | `https://api.verifox.ai` | Verifox API base URL |
| `VERIFOX_API_KEY` | (empty) | Per-user API key (`foxkey_*`), sent as `x-api-key` |
Generate a `foxkey_*` key from the Verifox dashboard (API Keys). The key
authenticates every tool call and is the account whose Fox Credits are charged
(verify and find cost 1 credit each; scoring and DNS scans are free).
