Available components
Dead
Every channel of this server has been unreachable for long enough to be marked dead. Its trust score is pinned to 0 and does not recover automatically: even once the server responds again it stays dead until it is manually reinstated.
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 connect, but we couldn't read the tool list to see what that exposes. 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 & Reachability0
- Transport check failed: declared streamable-http, but the endpoint returned HTTP 502. See how to fix → View diagnostics → Fail

Categories scored 0 because we could not verify them: authentication we do not have, an unreachable endpoint, or not enough scan history. We only credit what we can confirm.
How do I install the Email Verification MCP server?
Email Verification MCP is a hosted endpoint at https://email-verify-mcp-production.up.railway.app/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 →
batch_lead_score ~200
Score a batch of B2B leads in one call and get them back ranked best-first — the volume play for prioritizing a prospect list. Each lead is scored 0-100 (A-F) on email deliverability + domain credibility; returns a ranked result array plus a grade distribution and average score. Up to 100 leads per call. PAID: $0.01 USDC per lead, minimum $0.05, after the daily free allowance. On a 402, pay the returned Solana memo and re-call with the SAME args plus payment_tx=<signature>. An Authorization: Bearer fnet_ key bypasses payment.
| Name | Type | Req | Description |
|---|---|---|---|
| agent_id | – | – | stable id for your agent (scopes the free-tier counter). |
| leads | array | yes | list of email addresses (max 100; deduped). |
| payment_tx | – | – | Solana tx signature, when re-calling after a 402. |
Structured output declared, but exposes no named fields.
No examples provided.
batch_verify ~198
Verify an array of email addresses in one call — the volume play for list hygiene and bulk lead enrichment. Returns a per-email result array (same signals as verify_email) plus a deliverable/disposable summary. Up to 100 emails per call; domain-level facts are cached and deduped, so repeat domains are cheap. PAID: $0.003 USDC per email, minimum $0.05, after the daily free allowance. On a 402, pay the returned Solana memo and re-call with the SAME args plus payment_tx=<signature>. An Authorization: Bearer fnet_ key bypasses payment.

Structured output declared, but exposes no named fields.
No examples provided.
brief_summary ~169
Get the top 5 signals from today's brief as structured JSON — a cheap sample of the full daily_brief. Returns the day's highest-priority items (no prose) so an agent can decide whether to buy the full brief. PAID: $0.50 USDC (vs the full daily_brief price). Defaults to today (UTC). On a 402, pay the returned Solana memo and re-call with the SAME args plus payment_tx=<signature>. An Authorization: Bearer fnet_ key bypasses payment.
| Name | Type | Req | Description |
|---|---|---|---|
| agent_id | – | – | stable id for your agent (scopes the free-tier counter). |

Structured output declared, but exposes no named fields.
No examples provided.
daily_brief ~240
Get the curated daily email-verification brief — the day's verification activity in one package: volume, deliverability mix, disposable-domain hit rate, and the most-queried + most-flagged domains. Each brief carries a MINT provenance attestation so a buyer can verify it was produced by this server, unaltered. PAID: $5 USDC per brief. Defaults to today (UTC); a brief expires at the next midnight UTC. On a 402, pay the returned Solana memo and re-call with the SAME args plus payment_tx=<signature>. An fnet_ Bearer key bypasses payment.
| Name | Type | Req | Description |
|---|---|---|---|
| agent_id | – | – | stable id for your agent (scopes the free-tier counter). |
| date | – | – | brief date YYYY-MM-DD (default today, UTC). |
| payment_tx | – | – | Solana tx signature, when re-calling after a 402. |
| stripe_token | – | – | Stripe Checkout Session id (cs_…), when re-calling after paying the Stripe payment link (alternative to x402). Can also be supplied via the X-Stripe-Token header. |
Structured output declared, but exposes no named fields.
No examples provided.
lead_quality_score ~219
Score a B2B lead 0-100 (grade A-F) from email deliverability + domain credibility — decide whether a lead is worth your outreach time before you spend it. Combines deliverable/MX validity, disposable & role-account & free- provider detection, and domain age (cross-enriched from the FoundryNet brand- intel network) into a single score, with named signals and a recommendation. PAID: $0.01 USDC per lead after the daily free allowance (25/day). On a 402, pay the returned Solana memo and re-call with the SAME args plus payment_tx=<signature>. An Authorization: Bearer fnet_ key bypasses payment.
| Name | Type | Req | Description |
|---|---|---|---|
| agent_id | – | – | stable id for your agent (scopes the free-tier counter). |
| domain | – | – | optional company domain (defaults to the email's domain). |

| payment_tx | – | – | Solana tx signature, when re-calling after a 402. |
Structured output declared, but exposes no named fields.
No examples provided.
mint_info ~51

Input schema present but exposes no named parameters.
Structured output declared, but exposes no named fields.
No examples provided.
verify_email ~200
Verify a single email address — deliverability and quality signals for lead enrichment, signup gating, and list hygiene.

Domain-level facts are cached 7 days. PAID: $0.005 USDC per query after a daily free allowance (25/day). On a 402, pay the returned Solana memo and re-call with the SAME args plus payment_tx=<signature>. An Authorization: Bearer fnet_ key bypasses payment.
| Name | Type | Req | Description |
|---|---|---|---|
| agent_id | – | – | stable id for your agent (scopes the free-tier counter). |
| string | yes | the email address to verify. | |

Is the Email Verification MCP server safe to use?
Email Verification MCP scores 0 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the Email Verification MCP server expose?
Email Verification MCP exposes 7 tools: verify_email, batch_verify, lead_quality_score, batch_lead_score, daily_brief, and 2 more. Their descriptions and schemas cost roughly 1,277 tokens of context every time the server is loaded.
Does the Email Verification MCP server require authentication?
No. We connected to Email Verification MCP without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the Email Verification MCP server still maintained?
Email Verification MCP has been unreachable for long enough that we treat it as dead, and its score is pinned to zero. We last reached this channel on 29 July 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
