Available components
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security57
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 6 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability80
- AI-judged instruction clarity (excellent).Pass
- Tool/resource definitions use about 544 tokens (~90/item across 6 items; 6 tools + 0 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 6 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 6 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
How do I install the ai.verifox/email-verifier MCP server?
ai.verifox/email-verifier is a hosted endpoint at https://mcp.verifox.ai/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
find_email ~106
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.
| Name | Type | Req | Description |
|---|---|---|---|
| domain | string | yes | Company domain, e.g. stripe.com |
| first_name | string | yes | Person's first name |
| last_name | string | yes | Person's last name |
| middle_name | string | – | Optional middle name for more permutations |
No output schema declared.
No examples provided.
find_emails ~101
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.
| Name | Type | Req | Description |
|---|---|---|---|
| contacts | array | yes | Contacts to find emails for |
| wait | boolean | – | Wait for results in this call (default true) |
No output schema declared.
No examples provided.
get_credits ~60
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 present but exposes no named parameters.
No output schema declared.
No examples provided.
get_job ~87
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.
| Name | Type | Req | Description |
|---|---|---|---|
| job_id | string | yes | Job ID from verify_emails / find_email / find_emails |
| type | string | yes | Job type: verify_bulk, find_single, or find_bulk |
No output schema declared.
No examples provided.
verify_email ~83
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.
| Name | Type | Req | Description |
|---|---|---|---|
| string | yes | Email address to verify | |
| proxy | boolean | – | Use a SOCKS5 proxy for the SMTP check |
No output schema declared.
No examples provided.
verify_emails ~107
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.
| Name | Type | Req | Description |
|---|---|---|---|
| emails | array | yes | Email addresses to verify |
| wait | boolean | – | Wait for results in this call (default true). Set false to just get a jobId. |
