What this MCP does

Finds business email addresses and verifies email deliverability for individual or bulk contact lists.

find_email
Find ONE person's business email from their name and company domain. Generates ~50 permutations and SMTP-verifies each, waits for the result, and returns the best match (or not_found). Charges 10 Fox Credits per find.
Input schema
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['first_name', 'last_name', 'domain'], 'properties': {'domain': {'type': 'string', 'description': 'Company domain, e.g. stripe.com'}, 'last_name': {'type': 'string', 'description': "Person's last name"}, 'first_name': {'type': 'string', 'description': "Person's first name"}, 'middle_name': {'type': 'string', 'description': 'Optional middle name for more permutations'}}, 'additionalProperties': False}
find_emails
Bulk-find business emails for a LIST of contacts (name + company domain each). Submits the list, waits for completion, and returns the found email per contact. Up to 1000 contacts. Charges 10 Fox Credits per contact. Large lists that don't finish quickly return a jobId to poll with get_job.
Input schema
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['contacts'], 'properties': {'wait': {'type': 'boolean', 'description': 'Wait for results in this call (default true)'}, 'contacts': {'type': 'array', 'items': {'type': 'object', 'required': ['domain'], 'properties': {'name': {'type': 'string', 'description': 'Full name (alternative to first_name/last_name)'}, 'domain': {'type': 'string', 'description': 'Company domain'}, 'last_name': {'type': 'string'}, 'first_name': {'type': 'string'}, 'middle_name': {'type': 'string'}}, 'additionalProperties': False}, 'maxItems': 1000, 'minItems': 1, 'description': 'Contacts to find emails for'}}, 'additionalProperties': False}
get_credits
Get the current Fox Credit balance for the Verifox account tied to the API key. Free — no credits charged. Use it to check remaining balance before a big verify/find run (verify = 1 credit/email, find = 10 credits/contact).
Input schema
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'properties': {}}
get_job
Check an async job started by verify_emails, find_email, or find_emails. Returns results if finished, otherwise the current status. Use the type shown in the submitting tool's response.
Input schema
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['job_id', 'type'], 'properties': {'type': {'enum': ['verify_bulk', 'find_single', 'find_bulk'], 'type': 'string', 'description': 'Job type: verify_bulk, find_single, or find_bulk'}, 'job_id': {'type': 'string', 'description': 'Job ID from verify_emails / find_email / find_emails'}}, 'additionalProperties': False}
verify_email
Verify whether ONE email address is deliverable. Checks syntax, MX, SMTP, catch-all, disposable, free-provider and role detection, and returns a 0-100 quality score. Charges 1 Fox Credit per uncached email.
Input schema
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['email'], 'properties': {'email': {'type': 'string', 'format': 'email', 'description': 'Email address to verify'}, 'proxy': {'type': 'boolean', 'description': 'Use a SOCKS5 proxy for the SMTP check'}}, 'additionalProperties': False}
verify_emails
Bulk-verify a LIST of email addresses. Submits the whole list, waits for completion, and returns one result per email (same fields as verify_email). Best for cleaning lead lists. Charges 1 Fox Credit per email. Large lists that don't finish quickly return a jobId to poll with get_job.
Input schema
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['emails'], 'properties': {'wait': {'type': 'boolean', 'description': 'Wait for results in this call (default true). Set false to just get a jobId.'}, 'emails': {'type': 'array', 'items': {'type': 'string', 'format': 'email'}, 'maxItems': 100000, 'minItems': 1, 'description': 'Email addresses to verify'}}, 'additionalProperties': False}
